INSTALLATION

WARNING
Thermostat installation and all components of the control system shall conform to Class II circuits per the NEC code.

Remove Old Thermostat
A standard heat/cool thermostat consists of three basic parts:

1. The cover may be either a snap-on or hinge type.
2. The base, which is removed by loosening all captive screws.
3. The switching subbase, which is removed by unscrewing the mounting screws that hold it on the wall or adapter plate. Before removing wires from the old thermostat, label each wire with the terminal designation from which it was attached. Disconnect the wires from the old thermostat one at a time. Do not let wires fall back into the wall.

Installing New Thermostat

1. Pull the thermostat body off the thermostat base. Forcing or prying on the thermostat will cause damage to the unit.
2. Place the base over the hole in the wall and mark mounting hole locations on the wall using the base as a template.
3. Move the base out of the way. Drill mounting holes. If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten the base snugly, use plastic screw anchors to secure the base.
4. Fasten the base snugly to the wall using the mounting holes shown in Figure 2 and two mounting screws. Levelling is for appearance only and will not affect thermostat operation.
5. Connect wires to the terminal block on the base.
6. Push excess wire into the wall and plug the hole with a fire-resistant material (such as fibreglass insulation) to prevent drafts from affecting thermostat operation.
7. Carefully line the thermostat up with the base and snap into place.

SS/HP Switch (Conventional or Heat Pump Selection)
The SS/HP switch is factory set to the SS position. In this posi-tion, the thermostat is confi gured as a conventional single stage. If you have a single- stage heat pump system, switch SS/HP to the HP position (see figure 2).

Gas/Elec Switch (Fan Option)
The GAS/ELEC switch is factory set to the GAS position. In this position, the thermostat will not power the circulator fan on a call for heat but will power the circulator on a call for cool. If your system requires that the thermostat power the circulator fan on a call for heat, this switch should be set to the ELEC position. Typically, gas and oil heating systems do not require the thermostat to power the circulator fan during a call for heat. If your heat is gas or oil, the switch should be set to the GAS position.

When the thermostat is configured for a Heat Pump, the thermostat will always power the circulator fan on a call for heat in the HEAT mode.

Batteries
2 “AA” alkaline batteries are included in the thermostat. To install the batteries, pull the battery door as shown by the arrow and lift it open. Using the polarity indicated inside the battery door, insert the batteries. To close the battery door, swing the door down while pulling in the direction of the arrow. Once fully down, snap the door back into position.

To replace the batteries, set the system to OFF, following the instructions above.

The thermostat can be powered by system AC power or a Battery. If is displayed, the thermostat is battery-powered. If is not displayed, the thermostat is system-powered with optional battery backup. When the battery power remaining is approximately half, they will be displayed. When “Change ” is displayed, install fresh “AA” alkaline batteries immediately. For best results, replace all batteries with a premium brand alkaline battery such as Duracell® or Energizer ®. We recommend replacing batteries every 2 years. If the home is going to be unoccupied for an extended period (over 3 months) and is displayed, the batteries should be replaced before leaving. When less than two months of battery life remain, the setpoint temperature will offset by 10 degrees (10 degrees cooler in Heat mode / 10 degrees warmer in Cool mode). If offset occurs, the normal setpoint can be manually reset with or . Another offset will occur within two days if batteries are not replaced.

WIRING CONNECTIONS

Refer to equipment manufacturers’ instructions for specifi c system wiring information. After wiring, see the CONFIGURATION section for proper thermostat confi duration. Refer to 37-6754 for 1F80-0471 wiring diagram specifi cations.

1. Select Reversing Valve Output (SS/HP switch must be set at HP, omitted if SS/HP switch is SS Position) – The O/B option is factory set at “O” position. This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B option should be set at “B” position.

2. Program Options 1F80 only – This control can be confi gured for 5/2 day or 5/1/1 day programming or non-programming mode. The default setting is P2, indicating 5/2 day programming. The programs per week can be toggled to P3 or P0 by pressing the or keys. A selection of 0 Days for non-programmable will eliminate the need for EMR, and that step in the menu will be skipped.

3. Select Cool Savings™ and value – Select the Cool Savings feature On or OFF. If selected On, press MENU to select the amount of adjustment for the feature in Cool mode with 1 (1°) being the least amount of adjustment and 6 (6°) being the most amount of adjustment. The default value is 3 (3°). In normal operation “Saving” will appear under “Fan”.
   Cool Saving is an optional energy-saving feature that can reduce your cooling costs. It is based on the principle that lower indoor humidity makes a slightly higher temperature feel more comfortable. Cool Savings operates during periods of high demand which normally occur on the hottest summer days when the cooling system may run for hours to reach the thermostat setting. Long cooling run times also lower the indoor humidity. Cool Savings very slowly adjusts the setpoint temperature to make the setpoint closer to the displayed temperature, to a maximum number of degrees selected. Adjusting the setpoint temperature over a long cooling run time allows the system to reach your set temperature and turn off. The room temperature will be higher than the thermostat displays, but the reduction in humidity will allow comfort at the slightly higher temperature. When Cool Savings is making adjustments, “Save” will show next to the setpoint temperature and the room temperature may vary within the adjustment range selected. If this feature is selected OFF, no change will occur when the cooling system is continually running during periods of high demand.

4. Energy Management Recovery: (this step is skipped if confi gured to be non-programmable).
   Energy Management Recovery (E) On enables the thermostat to start heating or cooling early to make the building temperature reach the program setpoint at the time you specify. Heating will start 5 minutes early for every 1° of temperature required to reach setpoint.
   Example: If E On is selected have your heating pro-grammed to 65° at night and 70° at 7 AM. If the building temperature is 65°, the difference between 65° and 70° is 5°. Allowing 5 minutes per degree, the thermostat setpoint will change to 70° at 6:35 AM. Cooling allows more time per degree because it takes longer to reach a set temperature.

5. 5, 6 & 7) Cycle Rate Selection – The factory default settings with SS/HP switch in SS position for Heat is a medium cycle (ME) and Cool is a fast cycle (FA). For Heat Pump (HP), the default setting is a fast cycle (FA).
   To change the cycle rate, press the or key.
   Cycle rate differentials for different settings are:

   • MODE
   • Fast FA
   • Medium ME
   • Slow SL
   • Heat (SS) 0.4°F 0.6°F 1.8°F
   • Cool (SS) 1.2°F – 1.7°F
   • Heat Pump (HP) 1.2°F – 1.7°F

6. Select Compressor Lockout CL OFF or ON – Selecting CL ON will cause the thermostat to wait 5 minutes between cooling cycles. This is intended to help protect the compressor from short cycling. Some newer compressors already have a time delay built in and do not require this feature. Your compressor manufacturer can tell you if the lockout feature is already present in their system. When the thermostat compressor time delay occurs, it will fl ash the setpoint for up to fi ve minutes.

7. System Mode Confi guration – This thermostat is confi gured for Heat and Cool with Auto changeover (SYSTEM switch with Cool Off Heat Auto) default. It can also be confi guard for Heat and Cool (Cool Off Heat), Heat only with a fan (Off Heat), Heat only without a fan, Auto only (Auto-Off), and Cool only (Cool Off).

8. Select Backlight Display – The display backlight improves display contrast in low lighting conditions. When the “C” terminal is powered, selecting backlight CdL ON will keep the light on continuously. Select backlight OFF will keep the light on momentarily after any key is pressed. When the “C” terminal is not powered, the light will be on momentarily after any key is pressed no matter whether the backlight is selected ON or OFF.

9. Select Temperature Display Adjustment 4 LO to 4 HI. Allows you to adjust the room temperature display up to 4°higher or lower. Your thermostat was accurately calibrated at the factory, but you have the option to change the display temperature to match your previous thermostat. The current or adjusted room temperature will be displayed on the left side of the display.

10. Select F° or C° Readout – Change the display readout to Centigrade or Fahrenheit as required.

11. Select Filter Replacement Reminder and Set Run Time. Select the “Change Filter” reminder On or OFF. If selected On, press MENU to select the time from 25 to 1975 hours in 25-hour increments. In a typical system, 200 hours (default) of run time is approximately 30 days. After the se-lected time of blower operation, the thermostat will display “Change Filter” as a reminder to change or clean your air filter. When “Change Filter” is displayed, press the MENU button to clear the display and restart the time to the next filter change.

OPERATING YOUR THERMOSTAT

Choose the Fan Setting (Auto or On)

• Set the FAN Switch to Auto or On.

TROUBLESHOOTING

Reset Operation

Note: When the thermostat is reset, the installer configuration menu settings and programming will reset to factory settings. If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation, you can reset the thermostat by removing the wires from terminals R and C (do not short them together) and removing batteries for 2 minutes. After resetting the thermostat, replace the wires and batteries. If the thermostat has been reset and still does not function correctly contact your heating/cooling service person or place of purchase.

Note: Be sure to review the installer confi duration menu settings.

To reset the programming, clock and confi duration settings, press the FAN button simultaneously. The thermostat should go blank and then all segments will be displayed momentarily.

circuit breaker.

2. Furnace power switch to OFF.

3. Furnace blower compartment door or panel loose or not properly installed.

4. Loose connection to thermostat or system.

| Replace the fuse or reset the breaker. Turn the switch to ON.

Replace the door panel in the proper position to engage the safety interlock or door switch.

Tighten connections.

No Heat| 1. Pilot light not lit.

2. Furnace Lock-Out Condition. Heat may also be intermittent.

3. The heating system requires service or the thermostat requires replacement.

| Re-light pilot.

Many furnaces have safety devices that shut down when a lock-out condition occurs. If the heat works intermittently contact the furnace manufacturer or local HVAC service person for assistance.

Diagnostic: Set the SYSTEM Switch to HEAT and raise the setpoint above room temperature. Within a few seconds, the thermostat should make a soft-click sound. This sound usually indicates the thermostat is operating properly. If the thermostat does not click, try the reset operation listed above. If the thermostat does not click after being reset contact your heating and cooling service person or place of purchase for a replacement. If the thermostat clicks, contact the furnace manufacturer or an HVAC service person to verify the heating is operating correctly.

No Cool| 1. The cooling system requires service or the thermostat requires replacement.| Same as diagnostic for No Heat condition except setting the thermostat to COOL and lowering the setpoint below the room temperature. There may be up to a five-minute delay before the thermostat clicks in Cooling.
Heat, Cool or Fan Runs Constantly| 1. Possible short in wiring.

2. Possible short in thermostat.

3. Possible short in heat/cool/fan system.

4. FAN Switch set to Fan ON.

| Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under the terminal block. Try resetting the thermostat as described above. If the condition persists the manufacturer of your system or service person can instruct you on how to test the Heat/Cool system for correct operation. If the system operates correctly, replace the thermostat.
Thermostat Setting & Thermostat Thermometer Disagree| 1. The thermostat thermometer setting requires adjustment.| The thermometer can be adjusted +/- 4 degrees. See Temperature Display Adjustment in the Configuration Menu section.
The furnace (Air Conditioner) Cycles Too Fast or Too Slow (narrow or wide temperature swing)| 1. The location of the thermostat and/or the size of the Heating System may be influencing the cycle rate.| Digital thermostats provide precise control and cycle faster than older mechanical models. The system turns on and off more frequently but runs for a shorter time so there is no increase in energy use. If you would like an increased cycle time, choose SL for the slow cycle in the Configuration menu, steps 6 (heat), 7 (cool) or 8 (heat pump). If an acceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions.
