INSTALLATION
Ensure electric power to the system is disconnected at the main fuse or circuit breaker box before installation or service to prevent electrical shock and/or equipment damage.
Install additional alarms or limit controls if the failure of this control could result in personal injury and/or property damage.
This control functions as a temperature control, not a temperature limit control.
Fig. 1 Control Front View and Description
The control features a digital display showing SENSOR and SETTING temperatures, a STATUS indicator LED, a MENU button, and UP (+) and DOWN (-) buttons. The Green Status Indicator LED and display backlight may briefly turn off during a call for heating or cooling, indicating a normal self-check lasting up to 15 seconds. Load power is maintained during this period.
The user can select whether the setpoint represents the Cut In or Cut Out temperature. Careful understanding of this selection is crucial for correct operation, especially when setting the differential, to avoid unintended operating ranges.
Switch Settings
Switch SW1 must be set according to the system mode:
| System Mode | SW1 Setting |
|---|---|
| Refrigeration | Cool |
| Heating | Heat |

Wiring Instruction Notes
Switch Settings (SW2)
Switch SW2 must be set for the application:
| Application | SW2 Setting |
|---|---|
| Line Voltage (Power Stealing) | PS |
| Line Voltage (Non-Power Stealing) | Non PS |
| 24 VAC (Non-Power Stealing) | Non PS |
Power Stealing
Power Stealing is a feature that allows the control to be powered by the system it controls, eliminating the need for a separate neutral wire connection. This can save installation time and cost. However, there are compatibility limitations:
| Application | Power Stealing | Non-Power Stealing |
|---|---|---|
| Line Voltage, replacing existing control with a common wire | Yes | Yes |
| Line Voltage, load > 2.5 amps, without Defrost timer or other power interruption circuit, with or without alarm | Yes | Yes |
| Line Voltage, load > 2.5 amps, with Defrost timer or other power interruption circuit, no alarm | See Note 1 | Yes |
| Line Voltage, load > 2.5 amps, with Defrost timer or other power interruption circuit, with alarm | No | Yes |
| Line Voltage, load < 2.5 amps | No | Yes |
| 24 VAC Application | No | Yes |
NOTE 1: During defrost or when the load circuit is broken, the display will be blank as power is interrupted. All settings are restored when power returns.
Note: Only one sensor (PTC or NTC) may be connected. The sensor must meet specific temperature vs. resistance specifications.
Wiring Diagrams
The document includes wiring diagrams for Line Voltage Applications (Power Stealing and Non-Power Stealing) and 24 VAC Applications (Non-Power Stealing).
USER MENU OPERATION
The control has user-configurable menu settings that determine its operation. Factory default settings are applied upon shipment. To reset all settings to factory defaults, press and hold the MENU, DOWN, and UP buttons simultaneously for approximately 5 seconds.
To view menu items, press and hold MENU for 5 seconds. The display will show the first menu item on the left and its setting on the right. Use the UP or DOWN keys to change the setting. A momentary press of the MENU key advances to the next menu item. Pressing MENU after the last item (aL) returns the control to operating mode.
If you pass a desired menu item, you must cycle back through the menu or exit and re-enter menu mode. Changes are stored only when exiting the menu by pressing MENU at the last item. If no buttons are pressed for ten minutes in the menu, changes are lost, and the control returns to operating mode.
Note: The Heat/Cool switch (SW1) must be set correctly before configuring menu options.
User Menu Items:
| Menu Item | Description | Factory Default | Options | Comments |
|---|---|---|---|---|
| CF | Temperature Scale | F | C or F | Selects temperature display in Fahrenheit or Celsius. |
| dFF | Differential | 5 | 1 to 30 | Selects the range between Cut In and Cut Out. |
| SP | Set Point Mode Cool/Heat | Cl / CO | CO or Cl / Cl or CO | Selects how the setpoint temperature operates the load terminal. Cl = Cut In, CO = Cut Out. |
| SOF | Sensor Operation Failure Cool/Heat | 1 / 0 | 0 or 1 / None | Defines load relay operation during sensor failure. Cool mode: 1 (default) closes contacts, 0 opens contacts. Heating mode: contacts open on failure. |
| dL | Display Light | Off | On or Off | Controls the LCD display backlight. Off: illuminates on button press, then off after 10 seconds. On: remains continuously lit. |
| ASd | Anti Short-Cycle Delay | Cool: 1 / Heat: 0 | 0 to 12 | Minimum time (in minutes) load contacts remain open after a cycle. Prevents compressor damage. A blinking icon indicates delay is active. Setting 0 disables the feature. |
| LP | Lock Front Panel Keypad | Off | On or Off | Locks keypad to prevent unauthorized access. To unlock, press and hold MENU for 5 seconds. |
| OFS | Ambient Temperature Offset | 0 | -4 to +4 | Adjusts displayed temperature to compensate for installation variations. |
| bln | Binary Input | Off | On or Off | Enables an external input (switch/relay) to initiate a temperature set back. |
| Sb | Set Back | 0 | 0 to 50 | Determines the degree change in setpoint when the binary input is active. |
| AL | Alarm | 0 | 0 to 99 | Sets the time delay (in minutes) before a Temperature Out of Range alarm is triggered. Setting 0 disables the alarm relay. |
OPERATION
This control is a temperature control, not a temperature limit control. Do not use for heating water for bathing, washing, hot tubs, or similar applications to prevent scald injury.
The factory default setpoint is 45°F (7°C) for Cool and 120°F (49°C) for Heat. Setpoints can be adjusted using the UP/DOWN keys. Settings are retained during power loss.
The operating temperature range is determined by the Set Point (SP) mode (Cut Out or Cut In) and the Differential (dFF) setting.
Note: SW1 must be set to the correct mode (Cool or Heat) before setting options.
COOL/REFRIGERATION
Set SW1 to Cool. The snowflake (❄️) icon will display.
- Setpoint as Cut In: Temperature Range = Setpoint - Differential. Example: Setpoint 40°F, Differential 5°F = 35°F to 40°F range.
- Setpoint as Cut Out: Temperature Range = Setpoint + Differential. Example: Setpoint 40°F, Differential 5°F = 40°F to 45°F range.
HEAT
Set SW1 to Heat. The flame (?) icon will display.
- Setpoint as Cut Out: Temperature Range = Setpoint - Differential. Example: Setpoint 100°F, Differential 5°F = 95°F to 100°F range.
- Setpoint as Cut In: Temperature Range = Setpoint + Differential. Example: Setpoint 100°F, Differential 5°F = 100°F to 105°F range.
Lock Panel (LP)
To lock the keypad, set the LP menu item to 'On'. To unlock, press and hold the MENU key for 5 seconds, then press UP/DOWN to change to 'Off', and press MENU again.
Binary Input (bln) and Set Back (Sb)
When 'bln' is set to 'On', an external switch connected to BIN and GND terminals can initiate a temperature set back. 'Sb' determines the degree change. In Heat mode, the setpoint decreases; in Cool mode, it increases. 'bln' appears on the display when active. Ensure the Alarm delay time (AL) is sufficient to avoid false alarms during set back adjustments.
Alarm (AL)
The control has an alarm relay for malfunctions. If AL is set to 0, the alarm is disabled. If AL > 0, the alarm indicates three error conditions: Temperature Out of Range, Power Loss, and Sensor Operation Failure. The value set for AL is the time delay (in minutes) for a Temperature Out of Range alarm.
- Temperature Out of Range: Alarm triggers if temperature deviates more than 5°F from the setpoint for the duration set in AL. Consider factors like defrost cycles or door openings when setting AL.
- Power Loss: If power fails, the alarm relay closes before total power loss. The load relay state depends on the SOF setting. Upon power restoration, alarm contacts open, and the load relay is subject to the ASd delay.
- Sensor Operation Failure (SOF): If the sensor wiring opens or shorts, 'SOF' (with 'SH' or 'SO') blinks. After a 1-minute delay (which resets if normal operation resumes), the alarm relay closes, and the load relay operates per the SOF setting.
Important Note on Power Stealing and Alarms: If using power stealing mode with the alarm feature, ensure no device (like a defrost timer) interrupts power to the control. If power interruptions occur, use a neutral wire connection and the non-power stealing mode to ensure continuous power for alarm functions.

Troubleshooting
- LCD display, backlight, and status LED turn off in Power Stealing mode: This is normal when power is interrupted by devices like defrost timers. Settings are retained. For alarm functions during power interruptions, use non-power stealing mode with a neutral wire connection.
- Display indicates "CaL" on power up: Control was not calibrated. Return for replacement.
- Unit does not turn on (LCD blank): Check wiring, power supply, terminal connections, and switch settings. If using Power Stealing, ensure the load draws at least 2.5A AC or wire for Non-Power Stealing. Avoid devices that interrupt the load line if the alarm feature is enabled.
- Temperature differential wider than set: The Anti-Short-Cycle delay may be overriding the call for heat/cool. Lower the Anti-Short-Cycle delay setting.
- False alarm sounds on installation/power up before setpoint is reached: Disable alarm (AL=0) until the setpoint is reached, then set the alarm delay time.
- False alarm sounds after customer changes setpoint: Disable alarm (AL=0) while the unit adjusts to the new temperature, then reset the alarm delay time.
- False alarm with Bin/Set Back: Ensure the alarm delay time (AL) is sufficient for the Set Back temperature to be reached. If not, reduce the Set Back value or consider not using the alarm feature.
- Alarm sounds for unknown reason: Ensure the AL delay time is sufficient to cover conditions where temperature may fluctuate (e.g., loading/unloading stock, door openings). If power is lost due to a defrost timer or other device, wire the control in Non-Power Stealing mode with a neutral line connection.
