Shut off electricity at the main fuse box until installation is complete. Ensure that electrical power is disconnected. 2. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. 3. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. 4. Disconnect the wires from old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL. 5. Install new thermostat using the following procedures. ATTENTION! This product does not contain mercury. However, this product may replace a unit which contains mercury. Do not open mercury cells. If a cell becomes damaged, do not touch any spilled mercury. Wearing nonabsorbent gloves, take up the spilled mercury and place into a container which can be sealed. If a cell becomes damaged, the unit should be discarded. Screw anchors W904 O/B switch Mounting hole Electric/Gas Mounting jumper hole (W904) Figure 1. Thermostat Base ELECTRIC/GAS JUMPER (Fan Option) Mercury must not be discarded in household trash. When the unit this product is replacing is to be discarded, place in a suitable container. Refer to www.thermostat-recycle.org for location to send product containing mercury. Read the following information before clipping the nonelectric heat jumper. If you are unsure of your application, contact a qualified service person. ATTACH THERMOSTAT BASE TO WALL If your emergency or auxiliary system will energize the blower, then jumper, W904, on the thermostat base must be cut (see fig. 1). 1. Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit. 2. Connect wires beneath terminal screws on base using appropriate wiring schematic (see figs. 2 through 4). 3. Place base over hole in wall and mark mounting hole locations on wall using base as a template. 4. Move base out of the way. Drill mounting holes. 5. Fasten base loosely to wall, as shown in fig. 1, using two mounting screws. Place a level against bottom of base, adjust until level, and then tighten screws. (Leveling is for appearance only and will not affect thermostat operation.) If you are using existing mounting holes, or if holes drilled are too large and do not allow you to tighten base snugly, use plastic screw anchors to secure subbase. 6. Push excess wire into wall and plug hole with a fire-resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation. 2 If your emergency or auxiliary heat system requires that the thermostat energize the fan circuit, do not cut jumper W904. OPTIONAL BATTERIES With two "AA" batteries installed, your thermostat will continuously display the temperature during a loss of AC power. O/B TERMINAL SWITCH SELECTION The O/B switch on this thermostat is factory set to the “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 switch must be moved to the “B” position.

The SL setting produces a longer heating/cooling cycle. Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system just under .75°F and the SL setting cycles at approximately 1.2°F. 3) Select FA or SL (Fast or Slow) Auxiliary or Emergency Cycle Rate - The FA setting is frequently used for gas, oil or electric heat. The SL setting produces a longer heating cycle. Both settings produce very accurate temperature control and can be set to your personal preference. FA cycles the system just under .6°F and the SL setting cycles at approximately 1.°F. 4) Select backlit display (d-L OFF or ON) - The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on continuously. Selecting OFF will keep the light off. 5) Select filter replacement run time - The thermostat will display FILTER after a set time of operation. This is a reminder to change or clean your air filter. This time can be set from 0 to 1950 hours in 50 hour increments. A selection of 000 will cancel this feature. When FLTR is displayed, you can clear it by pressing and at the same time. This resets the timer and starts counting the hours until the next filter change. Contact your heat pump manufacturer for a specific replacement/maintenance interval. 6) Select Compressor Lockout (LOC OFF or ON) - Selecting LOC ON will cause the thermostat to wait 5 minutes before Select filter replacement run time Select temperature display adjustment higher or lower Returns to normal operation turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum 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 feature is already present in their system. When the thermostat compressor time delay occurs it will flash the Snowflake or Flame icon for about five minutes. 7) 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 right side of the display. 8) SelectTemperature Display (°F or °C) - Changes the display readout to Celsius or Fahrenheit as required. The current room temperature will be displayed on the right side of the display. 9) Select Fast second stage - In the RUN mode, if the temperature is manually raised by 3°F (2°C) or more above room temperature using and the fast second stage feature is enabled, FA on, the second stage will energize immediately. With FA off, the second stage will not energize until the setpoint temperature is 10°F or more above room temperature. 5 OPERATION OPERATING FEATURES SETTING THE THERMOSTAT Now that you are familiar with the thermostat buttons and display, read the following information to learn about the many features of the thermostat. This thermostat is very easy to operate. Set the SYSTEM switch to either HEAT or COOL then press and until the temperature you want to maintain is shown on the right side of the display. If you want to turn the system off, just move the SYSTEM switch to OFF. • SIMULTANEOUS HEATING/COOLING SETPOINT STORAGE — You can enter both your heating and cooling setpoints at the same time. There is no need to change the thermostat at the beginning of each season. • CONFIGURATION MENU — Allows you to customize certain thermostat options. The FAN switch controls the fan operation. When the FAN switch is set to AUTO, the fan will cycle with the furnace or air conditioner. When the FAN switch is set to ON, the fan will run continuously, regardless of SYSTEM switch position. TROUBLESHOOTING Reset Operation If a voltage spike or static discharge blanks out the display or causes erratic thermostat operation you can reset the thermostat by changing the system from Off to Heat while pressing , at the same time. If the thermostat has power, has been reset and still does not function correctly contact your heating/cooling service person or place of purchase. Symptom Possible Cause Corrective Action No Heat/No Cool/No Fan (common problems) 1. Blown fuse or tripped circuit breaker. 2. Furnace power switch to OFF. 3. Furnace blower compartment door or panel loose or not properly installed. 1. System Switch not set to Heat. Replace fuse or reset breaker. Turn switch to ON. Replace door panel in proper position to engage safety interlock or door switch. Set System Switch to Heat and raise setpoint above room temperature. Verify thermostat and system wires are securely attached. Diagnostic: Set System Switch to Heat and raise the setpoint above room temperature. Within five minutes 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 a service person to verify the heating system is operating properly. Set System Switch to Cool and lower setpoint below room temperature. Verify thermostat and system wires are securely attached. Same procedure as diagnostic for No Heat condition except set the thermostat to Cool and lower the setpoint below the room temperature. There may be up to a five minute delay before the thermostat clicks in Cooling if the compressor lock-out option is selected in the configuration menu (Item 6). Check each wire connection to verify they are not shorted or touching together. No bare wire should stick out from under terminal screws. 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. Item 2 in the Configuration Menu is the adjustment that controls the cycle rate. If an acceptable cycle rate is not achieved using the FA (Fast) or SL (Slow) adjustment contact a local service person for additional suggestions.
