EcoNet Enabled Unit Coolers are intelligent, electronically operated evaporators for walk-in coolers and freezers designed for easier installation and energy savings. Developed in conjunction with Rheem Manufacturing, it builds on the success, reliability, and efficiency of the EcoNet technology and brings it to commercial refrigeration.

EcoNet Enabled Unit Coolers save energy in refrigeration systems through precise superheat and space temperature control, fan cycling, and controlling how often the system goes into defrost based on compressor runtime.

It eliminates unnecessary defrosts, maximizes energy efficiency with less compressor runtime, reduces liability by eliminating icing issues, reduces fan speed to 50% during off cycle to save energy, and reduces temperature fluctuations by regulating defrosts for improved product quality. EcoNet Enabled Unit Coolers can be configured to work on a single or dual evaporator coil and can be used with a condensing unit in single and multiple evaporator installations as a group.

OPERATIONAL OVERVIEW
REFRIGERATION MODE
When the controller is powered up it will go through an initial startup procedure driving the EXV closed to ensure the valve is properly sealed. After 1 minute, if the space temperature is higher than the Space Temp Setpoint, the controller will start a cooling cycle and open the EXV in an attempt to cool the space.
During normal refrigeration mode, the EXV will continuously modulate to maintain superheat setpoint. The evaporator fans will turn on when Evap Temp drops below the Fan Delay Temp setting. To prevent compressor short cycling, the active refrigeration mode will run for a minimum of 5 minutes (adjustable via Cmp. Min Run Time; see pages 12-13 for Basic Settings).
When the space temperature drops below the Space Temp Setpoint, the EXV will close forcing a pump down, and the fans will cycle to half speed. To prevent compressor short cycling, this inactive mode will run for a minimum of 2 minutes.
When the space temperature rises 2 degrees above the Setpoint (can be adjusted via Setpoint Control parameter, see pages 12-13 for Basic Settings), the EXV will open again and then fans will cycle back to full speed.

UNIT COOLERS // ECONET ENABLED

PAGE 23

DEFROST MODE
TIMED DEFROST (DEFAULT SETTING) With the controller set to Timed defrost, the defrost start time will vary depending on compressor run time. The controller will automatically start defrost when the Def. Comp. Run Time has elapsed (default 360 minutes), or manually when set by the user on the display ServiceDefrost ControlStart Defrosting.
NOTE: When the unit is actively cooling the space (EXV is metering, fans running at full speed) the controller is counting runtime towards the next defrost. When the space temperature setpoint is satisfied (EXV closes for pumpdown, fans running at half speed) the controller does not count this as runtime towards the next defrost.
ADAPTIVE DEFROST (OPTIONAL SETTING) With Adaptive defrost selected, the controller continuously monitors coil operation as indicated by EXV position over time and by temperatures. When both EXV and temperature conditions degrade past a certain point, the controller will automatically start a defrost cycle. Otherwise, a defrost will be started anyway after the Def. Adpt. Run Time (default 720 minutes) has expired. Alternatively, a defrost can be manually started by the user via the display by navigating to ServiceDefrost ControlStart Defrosting.
NOTE: Adaptive defrost is only available when the controller is set to Freezer. If the controller is set to Cooler, Timed defrost will always remain as the functional setting.
When a defrost cycle starts, the EXV will close for pumpdown.
If unit is set as “Freezer”, the electric heaters will be energized via the defrost relays after a short delay (if Defrost Pump Down Delay is configured), and the fans will cycle off. Defrost will end when evaporator coil reaches termination temperature or when Max. Defrost Run Time has elapsed (whichever comes first). The unit will then begin a 5-minute drain time. After the drain time has finished, the unit will resume normal refrigeration operation: EXV opens, and fans turn on when Evap Temp drops below Fan Delay Temp setting.
If unit is set as “Cooler” the fans will remain on after the EXV has closed. Defrost will end when evaporator coil reaches termination temperature or when Max. Defrost Run Time has elapsed (whichever comes first). After the defrost cycle ends, the unit will resume normal refrigeration operation: EXV opens and fans will run when Evap Temp drops below the Fan Delay Temp setting.
NOTE: If there is a power loss while the unit is in the middle of an automatic defrost cycle, the controller will keep the EXV closed. When power is restored, the controller will go through its initial startup before resuming the defrost cycle. When the defrost cycle ends, the controller will resume refrigeration functions.

RECOMMENDED FREEZER DEFROST PARAMETER SETTINGS · Low Profile Evaporators: Set Defrost Termination Temperature between 55°F and 65°F. · Center Mount Evaporators: Set Defrost Termination Temperature between 35°F and 40°F (adjust as
necessary if defrost cycle is too long and steaming occurs); Coil Type should be set to Dual. · If defrost cycle is too long, keep in mind that the Max Defrost Time can also be adjusted down to
terminate defrost before steaming occurs. Default is 60 minutes. · If more defrost cycles are desired, the Runtime Until Defrost can be adjusted down so the unit will
defrost more often throughout the day. Default is 360 minutes (6 hours of runtime).

GROUP OPERATION

The EcoNet application supports multiple evaporator controllers to be connected together and work under a Leader/Follower setup as shown below. A maximum of 6 evaporators (1 Leader plus 5 Followers) can be configured onto a single group, and a maximum of 4 groups can be connected onto the same communication bus (see Figure 8). When multiple controllers are addressed and connected to work as a group, the Leader of each group will command its followers when to cool the space, when to pump down, and when to start a defrost.
Each group will work from a calculated average space temperature to determine if the space needs cooling. When a group is in active cooling mode, each evaporator in the group will meter its own EXV based on its individual superheat calculation.

The Leader will keep track of the system runtime and command the Followers in its group to start a defrost cycle as necessary. When a defrost cycle ends, the Leader will command the Followers in its group to start cooling the space simultaneously after every member of the group has finished defrosting.
Each controller to be connected on the communication bus should be powered up and addressed individually before being connected to the other controllers in the daisy chain.
To address each individual controller via the display select SettingsGroup Member Cfg. To “daisy chain” the units on the network, each unit should be connected to the EcoNet communication terminals (E1, E2, RT) as shown below. Use minimum 18 to 22 AWG shielded cable with shunt capacitance of 16 pF per foot and 100 ohm impedance.

DOOR SWITCH
The EcoNet evaporator controller can be paired with a door switch to pump down the system and turn off the fans. Please follow the steps below to wire and configure a door switch. 1. Wiring the Door Switch
Wire door switch or toggle switch to Digital Input #1 (terminals 1A and 1B) using 18-20 AWG wire. Input is a dry contact; no external voltage source needed.
2. Configuring the Door Switch Under Equipment, navigate to Door Sw. Config. Press SEL button, default setting (Off) will start flashing. Default setting is “Off”; can be configured as Normally Open (N.O.), or Normally Closed (N.C.).

Digital Input #1 (Door Switch Input) displayed on Status screen as ON

CONFIGURING DOOR SWITCH DELAY
Under Equipment, navigate to Door Sw.Time. Default 0 second delay: system will pump down and fans turn off immediately when Door Open Alert is generated. Delay can be configured for 30 seconds, 1 minute, 2 minutes, 3 minutes, 4 minutes or 5 minutes. With Door Switch configured as N.O. or N.C., contact has to be in its inactive state continuously for the configured Delay time before Door Open Alert is generated, system pumps down and fans turn off.
DOOR SWITCH SEQUENCE OF OPERATIONS With Door Switch configured, T003 Door Open Alert will cause system to pump down and fans to turn off immediately when Digital Input is in its inactive state (open contact for N.O. or closed contact for N.C.). Once system pumps down and fans turn off, a 2-minute minimum off time is observed where the EXV will remain closed regardless of Door Switch Input status. After Digital Input changes back to its active state and remains there for 5 seconds, the T003 Door Open Alert will clear, and system will be allowed to run again. If input changes back to its active state before the 2-minute minimum, fans will run at 50% speed. After the 2-minute minimum, cooling mode resumes (EXV opens, fans cycle to 100% speed). If Door Open Alert is generated during a defrost cycle (Air or Electric), defrost cycle continues unaffected. There is a mandatory 5-minute minimum cooling period following the defrost cycle, regardless of Door Switch input status. NOTE: The Door Open Alert does not reset the Space Temperature Alarm delay timer (set by Cmp. Run Time Alert under Settings), nor does it clear the “A108 Cooler/ Freezer not Satisfying Setpnt. Alert” once it has been generated. See Cmp. Run Time Alert setting on page 13.

PAGE 31

DOOR SWITCH SEQUENCE IN A GROUP
Only the group Leader needs the Door Switch wired and configured.
T003 Door Open Alert is generated at Leader when input is in inactive state for the configured Delay. Follower evaporators will receive pump down command from Leader and their fans will turn off.
Minimum 2 minute off time applies to entire Group. If Digital Input at Leader changes back to its active state before the 2 minutes are up, Leader and Followers will turn their fans to 50% after the Door Open Alert is cleared. After the 2 minutes have elapsed, Group resumes cooling as soon as the Door Open Alert has cleared.
If Door Open Alert is generated during a defrost cycle (Air or Electric), defrost cycle continues unaffected for the entire Group. There is a mandatory 5 minute minimum cooling period following the defrost cycle, regardless of Door Switch input status. Door Open Alert does not clear “A108 Cooler/Freezer not Satisfying Setpnt. Alert” or reset its timer count.

COMPRESSOR CONTROL
PACKAGED REFRIGERATION UNITS
The EcoNet Evaporator Controller can be set to cycle the compressor ON or OFF via Aux Relay 2 by configuring the Aux Relay Config. setting to Comp-Fan Control. The controller will use the Suction Pressure transducer reading to determine if the compressor needs to run. This setting is required for Packaged Refrigeration Units.

CONFIGURATION Aux Relay Config. Cut-Out Setpoint
Cut-In Offset

ADJUSTMENT RANGE Comp-Fan Control;Fan Control
-2 PSIG to 60 PSIG 10 PSIG to 50 PSIG

DEFAULT SETTING
“Comp-Fan Control” “0 PSIG” for Freezer units;”20 PSIG” for
Cooler units “20 PSIG”

1. Aux Relay Config.
a. Fan Control: Controller will use Auxiliary Relays 1 and 2 for Evaporator Fan ON/OFF control and fan speed control. This setting is applicable for all other evaporator unit models. Not applicable for Packaged Refrigeration Units!

b. Comp-Fan Control: Controller will use Auxiliary Relay 1 for Evaporator Fan ON/OFF control and Auxiliary Relay 2 for Compressor ON/OFF control based on Suction Pressure transducer reading.
NOTE: This setting only applies to Packaged Refrigeration Units. Packaged Refrigeration Units MUST be set to Comp Fan Control or damage to equipment could result!

UNIT COOLERS // ECONET ENABLED

PAGE 33

2. Cut-Out Setpoint: Pressure setpoint at which the compressor will turn off when Aux Relay Config. is set to Comp-Fan Control.

3. Cut-In Offset: Pressure differential for compressor to turn on when Aux Relay Config. is set to Comp-Fan Control.

COMPRESSOR OPERATION When a cooling cycle starts, the controller will open the Electronic Expansion Valve (EEV) which will cause the Suction Pressure to increase.
The compressor will turn ON when: Suction Pressure (PSIG) is greater than Cut-Out Setpoint + Cut-In Offset. The controller will keep the compressor on for a minimum amount of time while the EEV is open, even if the Suction Pressure briefly gets below the Cut-Out Setpoint to prevent compressor from short cycling.
Example 1 (Low Temperature Unit): Cut-Out Setpoint = 0 PSIG | Cut-In Offset= 20 PSIG Compressor will turn ON when Suction Pressure is greater than 20 PSIG. Compressor will turn OFF when Suction Pressure is less than 0 PSIG.
Example 2 (Medium Temperature Unit): Cut-Out Setpoint = 20 PSIG | Cut-In Offset= 20 PSIG Compressor will turn ON when Suction Pressure is greater than 40 PSIG. Compressor will turn OFF when Suction Pressure is less than 20 PSIG.
When a cooling cycle ends (setpoint is satisfied, defrost starts, etc.) the controller will close the EEV and the compressor will turn OFF.

LEAK DETECTION
The EcoNet evaporator controller can be paired with a leak detection device to assist with mitigation procedures in case of a refrigerant leak.
NOTE: THIS FEATURE IS INTENDED FOR USE WITH A2L REFRIGERANTS (R454A,R454C, R455A,R454B,R32). REQUIRES INSTALLATION OF A LIQUID LINE SOLENOID VALVE UPSTREAM, AND A SUCTION LINE CHECK VALVE DOWNSTREAM OF THE EVAPORATOR TO INTERRUPT REFRIGERANT FLOW WHEN A LEAK IS DETECTED.
WIRING THE LEAK DETECTOR DEVICE TO THE ECONET CONTROLLER
Wire the leak detector device to Digital Input #2 (terminals 2A and 2B) using 18-20 AWG wire.
Input is a dry contact; no external voltage source needed.
CONFIGURING THE LEAK DETECTOR INPUT Under Equipment, navigate to Leak Sw. Config. Press SEL button, setting will start flashing. Use UP or DOWN buttons to adjust to desired leak detector input operation. Press SEL button again to confirm change. It can be configured as Normally Open (N.O.), Normally Closed (N.C.), or Off to disable leak detector input.
Note: A2L evaporator models will come with a leak detector installed and this setting configured from the factory.

PAGE 39

NOTE: The leak alarm condition will also override the Door Switch and System Enable functions.
When Digital Input #2 becomes inactive, the controller will wait 10 seconds before resuming normal operation.
On group operation, each group member will generate a leak alarm only when their own individual leak detector input (Digital Input #2) becomes active.
When a group member generates a leak alarm, that group member will follow the steps described above. Other group members will also display “Leak Alarm Active” on their display screens but may continue their refrigeration functions if their respective leak detector inputs are not active.

LEAD/LAG
Lead/Lag will allow the linking of two redundant systems for backup cooling and ability to equalize compressor runtime between the two systems. This will be accomplished by designating one of the two evaporators to be the Manager, and the other evaporator to be the Partner. The controller designated to be the Manager will constantly communicate via the EcoNet communication port to the Partner controller. The Manager controller will monitor its own status as well as the Partner status and coordinate cooling operations between the two systems.
LEAD/LAG MANAGER SETUP To configure two controllers to work under Lead/Lag operation:
1. At the designated Partner controller, set the Instance number address. See Network Instance setting on Page 10.
2. Connect 18-22 AWG shielded wire between the two controllers at the EcoNet communication port.
3. At the designated Manager controller: a. Set the Instance number address. See Network Instance setting on Page 10 (must be different number from Partner). b. Set Lead/Lag Select to “Manager” c. Select Partner Instance number (same number configured on step #1; this is the address that the Manager will communicate with).
d. Set the Compressor Run Limit Hours to the desired switching time interval.

UNIT COOLERS // ECONET ENABLED

PAGE 41

e. Set the desired temperature Setpoint (Manager will sync Partner to the same Setpoint)
f. Set the desired Compressor Run Time Alert (Manager will sync Partner to the same run time alert setting)
NOTE: Manager will also sync Partner to the same Cooler/Freezer setting. LEAD/LAG SEQUENCE OF OPERATIONS Once both controllers are set up and communicating, the Manager controller will keep track of compressor runtime and coordinate operational turns between the Manager and Partner controllers. After the initial setup and synchronization the Manager controller will start first, and the Partner controller will remain disabled (EXV closed, fans off). When the Manager controller reaches its configured Compressor Run Limit Hours it will disable (EXV closed, fans off), and the Partner controller will continue cooling operation. The Manager will receive periodic updates on the Partner run time hours, and when the Compressor Run Limit Hours are reached the Partner will be disabled and the Manager will resume cooling operations. When the active controller (Manager or Partner) starts a defrost cycle, the inactive controller will remain disabled. When the next cooling cycle starts, the controller that underwent the defrost cycle will resume cooling operation until the Compressor Run Limit Hours are reached.

PAGE 42

INSTALLATION · MAINTENANCE · OPERATION
HTPG0425_IOM

If the active system (Manager or Partner) is unable to reach setpoint within the configured Compressor Run Time Alert setting:
1. The active controller will flag the “A108 Cooler/Freezer Not Satisfying Setpoint Alert” 2. The inactive system will be enabled to assist cooling operation 3. Both Manager and Parter will remain active until each satisfies its own Setpoint 4. When the next cooling cycle starts, the controller that did not flag the alarm on the previous
cycle will take first turn and continue cooling operation until the Compressor Run Limit Hours are reached. The controller that flagged the alarm on the previous cycle will remain disabled.
If at any time the communication between Manager and Partner is interrupted, each controller will individually resume cooling operations as needed, and each controller will flag “A005 Lead/Lag Communication Failure” alarm.
NOTE: To use the door switch function with two redundant systems linked for lead-lag operation, each system will need its own door switch with a single pole-single throw (SPST) contact, or one door switch with a double pole-single throw (DPST) contact. The Digital Input #1 on BOTH controllers must be inactive simultaneously for both systems to remain off with “Door Open Alert”. Otherwise, when one system is off due to “Door Open Alert”, the lead-lag operation will cause the other system to run. See Door Switch Operation on page 29 for more details.
