Wiring Diagrams (Fig. 3 and 4)
Conventional Thermostats
Conventional (RWYG) thermostats can be used to control conventional, multi-stage, and heat pump equipment. If the thermostat has a common terminal, it is wired to C on the panel, see Fig. 3. A multi-stage thermostat is wired with the second and third stage of heat to W2 and W3 on the panel thermostat connections, and with the second stage of cooling to Y2. Leave the zone O/B thermostat jumper on the TZ-4 disconnected. See Single and Multi-Stage Operation in the Operation section for instructions on staging the TZ-4.
The PC8900 with the W8900A or W8900C can be used as a zone thermostat. See Fig. 4 for hookup. This thermostat can be used to control up to 2 heat and 2 cool stages of conventional equipment. When used to control heat pump equipment, the W8900A is recommended.
Connect a jumper on the W8900 from Rc to Rh as shown in Fig. 4. Wire terminals R and C to a transformer. If the system current draw is within specifications, the R and C on the W8900 could alternately be connected to R and C on the TZ-4. The PC8900/W8900 draws 5 VA.

Wire the equipment, as applicable, to the TZ-4 as shown in Fig. 17-19. Refer to manufacturer instructions for additional wiring instructions and substitute the TZ-4 equipment terminals for the thermostat terminals shown. -- Wire first stage compressor to Y1, second stage
compressor to Y2. -- Connect auxiliary heat to W3/AUX and emergency heat to
W1/E. -- If auxiliary heat and emergency heat are the same, wire a
jumper from W1/E to W3/AUX. -- Connect changeover relay to O/B equipment terminal. -- Set DIP switch 5-7 to on for O (cool) changeover, or to off
for B (heat) changeover. -- Set DIP switch 5-1 to off for heat pump equipment.

After the installation is complete, verify correct operation: 1. Place the Em Heat switch in the Off (down) position. 2. Place the Zone-A-Lone switch in the Occup/Remote (up) position. 3. Verify that DIP switches are set correctly. See Sequence of Operation section and Table 8 for correct configuration. 4. Power up the TZ-4 and set the thermostats so no zones are calling. The board then enters the Purge mode where all dampers open and the fan operates for two or three and one-half minutes (configurable). (If there is no Discharge Air Temperature Sensor connected to the panel, the purge LED flashes in all modes other than purge.) The damper LEDs are green to indicate the dampers are open. Press Purge Override button on panel to exit Purge mode. 5. Set zone one thermostat to heat and raise the setpoint to call for heat. Verify that the heat LED is red and zone one damper remains green while the other damper LEDs turn off. 6. Raise zone two setpoint to call for heat. Lower zone one setpoint to stop the call for heat to that zone. Verify that zone one LED turns off and zone two LED turns green. 7. Repeat for zones three and four. 8. Alternately, lower the setpoint to call for cooling. Verify that the green cool LED illuminates.
OPERATION
Identifying DIP Switches
This panel has two banks of DIP switches, DIP switch 4 (S4) and DIP switch 5 (S5). Each bank has eight individual switches that are identified by two numbers; the first number is the bank number (4 or 5) and the second number identifies the individual switch. For example, DIP 5-1 is bank 5, switch 1.
Sequence of Operation
· When there is no call for heat, cool or fan, the board is in idle mode, no system LEDs are illuminated and the green damper LEDs indicate open.
· On a call for heat, cool, or fan, the calling zone damper stays open, and other zone dampers close: -- TZ-4 panel energizes the HVAC equipment and conditioned air is delivered to the calling zone. -- Heat LED (red), cool LED (green), or fan LED (green) illuminates to indicate equipment operation. -- Fan LED illuminates only on a call for circulation; it does not illuminate during a call for heat or cool. -- When the call is satisfied, the system enters the Purge mode. After purge, all dampers return to the Open position, depending on the setting of DIP switch S5-5.
· Any zone thermostat can call for heating or cooling. If there are co-existing calls for heat and cool, the panel accepts the first call.
· Once that call is satisfied, or a maximum of 20 minutes has elapsed, the panel switches to allow the opposite call after completing Purge mode.

Purge Mode
At the end of every call for heat or cool, the panel enters a Purge mode that holds open the calling zone damper for two (default) or three and one-half minutes.
During this time, the panel or the HVAC equipment can be configured to operate the fan. The Purge LED lights to signal that the system is in the Purge mode. Pressing the purge override button overrides the Purge mode.
Unless there is a new call for heat or cool during the Purge mode, all dampers are moved to the Open position at the end of purge.
The panel can be configured to open all dampers during the purge mode.

Individual Zone Fan Control
When all zones are satisfied, the fan switch of each thermostat controls the fan operation for that zone. -- When the fan switch is in the On position, the fan is
energized, and dampers close to zones where fan switch is in Auto position. -- During a call for heat or cool at this time, the circulation mode ceases, and the heat or cool call is honored. -- When the zone calling is satisfied, the circulation call resumes.

Single and Multi-Stage Operation
The panel can control up to three stages of heating and two stages of cooling: -- First stage is energized by the thermostat. -- Second stage of heating or cooling and third stage of
heating can be energized by the thermostat, timer, or the percentage of zones calling. (For instance, first and second stage of heat and cool can be thermostat energized and third stage heat can be configured for timer energizing.) -- See Tables 5 and 6 for second and third stage configuration. Note that second and third stage can be controlled differently. Set stages not used to Off.

DIP Switch bank 4, switches 1-4, are used to configure the staging method: -- Switches 1 and 2 configure second stage control. See
Table 4. -- Switches 3 and 4 configure third stage control. See Table.
5. -- When stage two or three is not used, disable that stage by
turning off the corresponding switches.

TZ-4 TOTALZONE® ZONE CONTROL PANEL

HEAT PUMP OPERATION The panel can control single- or two-stage heat pumps with or without auxiliary heat. Set DIP switch 5-1 to Off for heat pump control. This energizes equipment terminal Y1 on a call for first stage heat or cool. If second stage is configured to operate with DIP switch 4-1 and 4-2, Y2 energizes to call for second stage compressor. When in heat pump mode, the panel energizes the fan with a call for heat and a call for cool. Configure DIP switch 5-7 for correct changeover valve control. See Table 7.
DUAL FUEL OPERATION The panel can control a heat pump and a fossil fuel furnace in a dual-fuel application. A C7089B1000 Outdoor Temperature Sensor is wired to the OT and OT terminals on the TZ-4 to switch the panel from heat pump to fossil fuel operation. DIP switch 5-8 is set to Off to enable dual-fuel operation.
The dual-fuel OT setting (see Fig. 16 for location) is set to the outdoor temperature that locks out the heat pump and uses the fossil fuel mode. The fan is energized by the panel for two minutes after the changeover and the Em Ht LED illuminates when in the fossil fuel mode.
IMPORTANT A C7089B1000 Outdoor Temperature Sensor and a C7735A1000 Discharge Air Temperature Sensor are required for dual fuel operation.

TZ-4 TOTALZONE® ZONE CONTROL PANEL

Thermostat Operation
Conventional Thermostats
Conventional (R,W,Y,G) heat/cool thermostats can be used with the TZ-4 to control single or multi-stage gas, electric or oil systems and heat pumps with auxiliary heat.
The panel can be configured to control second stage heat and cool and third stage heat using a 5-60 minute timer, or staging can be controlled by the percentage of zones calling.
When using conventional thermostats on heat pump applications, set DIP switch 5-1 to Off for heat pump equipment. Set DIP switch 5-7 for correct reversing valve operation. See Table 7.
Heat Pump Thermostats
HEAT PUMP THERMOSTATS WITH SINGLE Y OUTPUT Thermostats that have a single Y terminal for first stage heat and cool and those with separate Y1 and W1 can be used. Thermostats of either wiring type can be used on any zone.
For thermostats with a single Y, the reversing valve wire must be connected to O/B: -- Connect the thermostat Y terminal to Y1 on the panel. -- If the thermostat energizes O on a call for cool, connect the
O/B jumper located near the thermostat wiring terminals. -- If the thermostat energizes B on a call for heat, leave the
O/B jumper disconnected.
HEAT PUMP THERMOSTATS WITH SEPARATE Y1 AND W1 TERMINALS Heat pump thermostats with separate Y1 and W1 terminals for first stage heat and cool are wired to Y1 and W1/E. Leave the O/B jumper, located near the thermostat wiring terminals, disconnected.
Emergency Heat Control
Emergency heat is defined as using an auxiliary heat source without using the heat pump. When the Em Heat switch is in the emergency heat position, the heat pump is locked out and calls for heat are sent to the W1/E equipment terminal for fixed stage emergency heat. Second stage emergency heat energizes equipment terminals W3/Aux. Second stage emergency heat is configured with DIP switch S41 and 2. When the panel is in the heat pump mode, W1/E is energized only in emergency heat.
A recommended heat pump thermostat can also control emergency heat from the thermostat system switch. See Table 1.

Multi-Stage Thermostats
Use multi-stage thermostats to control up to three stages of heat and two stages cool with the W1/E,W2, W3/AUX, Y1, and Y2 thermostat terminals.
Manual and Automatic Changeover Thermostats
Manual or automatic changeover thermostats can be used. The panel determines the call for heat or cool based on which was called for first. Subsequent calls for heat or cool are honored when the initial call is satisfied, or 20 minutes has elapsed.
Rebooting Microprocessor
To reset the panel, press and release the Boot button.The system reboots and enters the Purge mode.
Discharge Air Temperature Sensor
The C7735A1000 Discharge Air Temperature Sensor (not included) is a supply-duct-mounted temperature probe used to control capacity and prevent high limit or coil-icing. The sensor attaches to the two DATS terminals on the panel. When a high or low limit is reached, the panel shuts off the equipment and keeps the fan operating for 2-1/2 minutes. After this time, it re-energizes the equipment after the discharge air recovers by 10 degrees. When the DATS exceeds the high or low limit, the Heat (red) or Cool (green) LED flashes.
Set the temperature from 110°F to 160°F. See Fig. 23. The recommended setting for fossil fuel/ electric systems is 160°F (default factory setting). For heat pump systems, the recommended setting is 120°F. When using a heat pump with dual fuel activated (DIP 5-8), the high limit will automatically be set for 120 degrees when the outputs call for compressor only operation. When the outputs call for nonheat pump operation, the high limit will be set to the adjustable 110° to160°F setting.
The cooling temperature limit can be set at 40°F or 48°F.

Zone-A-Lone Switch
When the Zone-A-Lone switch is in the occupied (up) position and the OC/OC terminals are not used, the system functions as a zone control system.
When switched to the unoccupied (down) position, all dampers are opened and all requests for heat, cool, or fan, except from zone one, are not honored.
The zone one thermostat becomes the controlling thermostat for the entire system. During long unoccupied periods, one thermostat can be set back instead of adjusting each zone thermostat in the building.
The T8601D2027 and T8611G2051 include two OC terminals. When wired to the TZ-4 OC terminals, and with the Zone-ALone switch in the occupied (up) position, the board enters the unoccupied mode during the Leave and Sleep programs. This feature requires two extra wires to the Zone 1 thermostat.
Circuit Breaker Protection
A built-in thermal circuit breaker protects the TotalZone panel. This circuit breaker protects the panel against shorts in the thermostat and damper wiring. It does not protect against shorts in the wiring of the HVAC equipment into the panel.

When the circuit breaker is tripped, none of the LEDs illuminate and the yellow rectangular component located left of the R and C terminals is hot to touch. Remove power to the panel for at least five minutes to allow the circuit breaker to cool off and reset. To eliminate the short, verify the dampers and thermostat wiring.
Fan On In Heat
The system blower can be set to come on with a call for heat as required for hydro-air or electric heat systems. Set the blower function using DIP switch 5-6.
When DIP switch 5-1 is set to Off for heat pump control, the panel brings the fan on with a call for heat and a call for cool.

TotalZone Add-A-Zone Panels
Using TotalZone Add-A-Zone Panels, the system can be expanded to up to 32 zones using TAZ-4 Add-A-Zone panels. Two wires connect the AZ1 and AZ2 terminals on the TZ-4 to the matching terminals on the TAZ board(s).
See Fig. 15 and the TAZ installation instructions for more information.
