Installation and Wiring

Warning Disconnect power before beginning installation.

Thermostat Location
Install the thermostat approximately 5 feet (1.5m) above the floor in an area that has a good amount of air circulation and maintains an average room temperature.
Avoid installation in locations where the thermostat can be affected by drafts, dead air spots, hot or cold air ducts, sunlight, appliances, concealed pipes, chimneys and outside walls.

Install your new PROSTAT thermostat in 4 basic steps:

1. Install the sub-base
2. Connect your wires
3. Provide Power
4. Attach the thermostat to the sub-base

Install the Sub-Base:

• Remove the sub-base from the body of the thermostat.
• Mount the sub-base as shown below:

Provide Power

• For 24 Volt AC power, you must connect the common side of the transformer to the C terminal on the thermostat sub-base. In dual transformer installations, the transformer common must come from the cooling transformer.
• For battery power, insert the 2 supplied “AA-type alkaline batteries into the battery compartment located in the rear housing of the thermostat. Make sure to position the Positive (+) and Negative (-) sides of the batteries correctly with the +/- symbols in the battery compartment.
• If connecting this thermostat to a Wi-Fi network, a 24 VAC common (C wire) is required for the following system types:
  • Heat Only
  • Cool Only
  • Single-Stage Heat Pump
  • Multistage Heat Pump
    NOTE: If a common “C” wire is not being used, the 2 “AA” batteries must be installed.

NOTES – Installer Settings

1. Only available if a 2 or 3-stage system type was selected in option 4.
2. Only available if a Conventional system was selected in option 4.
3. Only available if a 2 or 3-stage Heat Pump system was selected in option 4.
4. Only available if a Heat Pump system was selected in option 4.
5. Only available if a programmable profile was selected in option 1.
6. Only available if auto changeover was enabled in option 8.
7. Only available if Installer Lock was enabled in option 19.

Detailed Explanation of Installer Settings (also see NOTES above):

1. Programming Mode – Select the programming mode, either full 7 day or 5-2 day (weekday/ weekend) programming or non-programmable.
2. Clock Format – Select either a 12 hour or 24 hour clock.
3. Temperature Scale – Select a temperature scale of either °F or °C.
4. System Type – Select the system type for your installation. NOTE: Changes made to this option will reset options 3, 5, 6, 7, 10, 11 and 12.
5. 1st Stage Differential – Selects a 1st stage temperature differential.
6. 2nd Stage Differential [note 1] – Selects a 2nd stage temperature differential.
7. 3rd Stage Differential [note 1] – Selects a 3rd stage temperature differential.
8. Auto Changeover – Selects auto changeover on or off. When auto changeover mode is enabled and selected, the system automatically switches between heating and cooling modes. There is a 5 minute delay when switching from heating to cooling or cooling to heating in auto changeover mode.
   NOTE: Also see “Auto Changeover Dead Band” in option 9.
9. Auto Changeover Dead Band [note 6] – When auto changeover mode is enabled in option 5 and selected, the system automatically switches between heating and cooling when the room temperature meets the normal criteria for either a heating or cooling call. There is a forced separation (dead band) between the heating and cooling set points so that the systems do not work against each other. This option selects the amount of this dead band in degrees with the default being 3° F.
10. 1st Stage Fan Control [note 2] – Selects a 1st stage fan control of either gas or electric heat.
11. Emergency Heat Fan Control [note 3] – Selects emergency heat fan control of either gas or electric heat.
12. Residual Cooling Fan Delay – Select a delay for the system fan after the cooling compressor has turned off.
    This delay will help remove the remaining cool air out of the ductwork providing additional efficiency.
13. Circulating Fan Lock – When enabled, the only user fan options available are ON and CIRC (Circulation).
    The AUTO option is not available with this option enabled.
14. Reversing Valve [note 4] – Selects the output state of the O/B terminal. Select O for this terminal to be active in the cool mode or select B for this terminal to be active in the heat mode.
15. Short Cycle Protection – Select the number of minutes the cooling compressor will be locked out after turning off. This short cycle protection is also active in the heat mode if a heat pump system was selected in Option 4.
16. Auxiliary Fossil Fuel Heat Pump Control [note 3] – When set to electric (AUX AE), both the compressor (1st stage) and auxiliary stage(s) will run when a call for auxiliary heat is made. When set to gas (AUX AG), the compressor stage(s) will be locked out one minute after a call for auxiliary heat.
17. adaptive Recovery Mode (early recovery) [note 5] – Enables or disables the ARMTM (adaptive recovery mode) feature. During ARM, room temperature is recovered by turning on the heating or cooling before the end of the setback period. The set point temperature is changed to that of the upcoming program temperature.
18. user Lockout Security Level – Selects the level of keypad lockout when the thermostat is locked.
    Level 2 locks the entire thermostat (including the front reset button). Level 1 locks everything except the or buttons, allowing for up and down temperature adjustment. Installer Settings can still be accessed with user lockout enabled.
    NOTE: The user lock code is set in the User Settings mode (see User Manual).
19. Installer Lock – When YES (Y) is selected, a 4-digit lock code can be entered in option #20 to lock out the
    Installer Settings Mode. Select NO to skip installer lock.
20. Installer Lock Code [note 7] – Select a 4-digit lock code (0-9) to lock the Installer Settings Mode.
    NOTE: Lock code cannot be 0000.
21. Heat Set Point Upper Limit – Selects the heating set point upper adjustment limit.
22. Heat Set Point Lower Limit – Selects the heating set point lower adjustment limit.
23. Cool Set Point Lower Limit – Selects the cooling set point lower adjustment limit.
24. Cool Set Point Upper Limit – Selects the cooling set point upper adjustment limit.
25. Installer Clear – Clears settings based on your selection. CLRO makes no changes and CLR2 clears ALL thermostat settings to factory default.
    WARNING: If you press RETURN after selecting CLR2 the clear will take place and the appropriate settings will be returned to factory defaults. If you do not wish to make any changes, use the or button to select CLRO.

System Testing

Warning Read Before Testing

• Do not short (or jumper) across terminals on the gas valve or at the heating or cooling system control board to test the thermostat installation. This could damage the thermostat and void the warranty.
• Do not select the COOL mode of operation if the outside temperature is below 50º F (10º C). This could possibly damage the controlled cooling system and may cause personal injury.
• This thermostat includes an automatic compressor protection feature to avoid potential damage to the compressor from short cycling. When testing the system, make sure to take this delay into account.
  NOTE: The compressor delay can be bypassed by pressing the reset button on the front of the thermostat.
  All user settings will be returned to factory default, however, all Installer settings will remain as originally programmed in section 4.

1. Press the SYSTEM button until the thermostat is in HEAT mode.
2. Using the button, raise the set temperature a minimum of 3 degrees above the current room temperature. The system should start within a few seconds. With a gas heating system, the fan may not start right away.
3. Press the SYSTEM until the thermostat is in the OFF mode. Allow the heating system to fully shut down.
4. Press SYSTEM until the thermostat is in COOL mode.
5. Using the button, lower the set temperature a minimum of 3 degrees below the current room temperature. The system should start within a few seconds (unless compressor short cycle protection is active – See note above).
6. Press the SYSTEM until the thermostat is in the OFF mode. Allow the cooling system to fully shut down.
7. Press FAN until the thermostat is in FAN ON mode. The system fan should start within a few seconds.
8. Press FAN until the thermostat is in FAN AUTO mode. Allow the system fan to turn off.
