Installation
Location
The 103 is designed for installation in climate controlled living spaces.
Place the unit in a central location with good circulation. For proper
temperature sensing, avoid exposing the 103 to heat radiated from lamps, sun
light, fireplaces or any other radiant heat source. Avoid locations close to
windows, behind doors or alcoves with poor air circulation, adjoining outside
walls, or doors that lead to the outside. Select a location that prevents the
103 from being directly exposed to air currents from supply registers or
ceiling fans. Mount the Control on a section of interior wall that does not
contain hot or cold water pipes or duct work
Mounting / Installation
Follow these steps to mount the 103 Control to the wall.
- Turn OFF all power to heating and cooling equipment.
- If an existing thermostat is being replaced:
- Record color and terminal marking of each wire.
- Disconnect the wires from the existing thermostat being careful not to allow them to fall back into the wall.
- Remove the existing thermostat from the wall.
- Pull the cover off the thermostat body. Forcing or prying on the thermostat will cause damage to the unit.
- Move base over hole in wall and mark mounting hole locations on wall using base as template. (See Fig. 1)
- Move base out of the way. Drill mounting holes. If you are using existing mounting holes pull thermostat wire bundle through the hole in the thermostat base. Secure sub-base to the wall. Leveling is for appearance only and will not affect thermostat operation.
- Connect wires to terminal block on base using appropriate wiring diagram.
- Push excess wire into wall and plug hole with a fire resistant material (such as fiberglass insulation) to prevent drafts from affecting thermostat operation.
- Two “AAA” alkaline batteries are included in the thermostat at the factory with a battery tag to prevent power drainage.
- Remove the battery tag to engage the batteries.
Configuration
Electric/Gas Jumper (Fan Option)
If your emergency or auxiliary system will energize the blower, then jumper
W906 on the thermostat base must be cut (see fig. 1). If your emergency or
auxiliary heat system requires that the thermostat energize the fan circuit,
do not cut jumper W906. If you are unsure of your application, contact a
qualified service person.
°F or °C Selection
The factory default setting for temperature display is Fahrenheit. If you want
the temperature in Celsius, clip jumper W904.
Fast or Slow Cycle Selection
The factory default setting is fast cycle, which cycles 1st stage at
approximately 1.2°F and 2nd stage 0.75°F. If you prefer slow cycle, clip jump
W905. The 1st stage and 2nd stage would be 1.5°F and 1.2°F respectively.
O/B Terminal Switch Selection
The O/B switch on this thermostat is factory set to “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.
Battery Location
This thermostat does not require batteries to operate. The 2 “AAA” alkaline
batteries are for the thermostat to remember the configuration menu selections
if AC voltage is lost. If the display shows BATT or when AC power is not
present, the batteries are low and should be replaced with fresh “AAA”
Energizer® alkaline batteries. For best results, replace all batteries with
new premium brand alkaline batteries. To replace the batteries, install the
batteries along the bottom (see fig. 2). The batteries must be installed with
the positive (+) ends to the right.

-
“BATT” or is displayed when 2 “AAA” batteries are low and should be replaced.
Whenever BATT or change appears in the display, new premium brand AAA alkaline batteries should be installed. If the house will be unoccupied for an extended period and BATT or change is displayed, install new batteries before leaving.
OPERATING FEATURES
NOTE: To prevent static discharge problems, touch side of thermostat to release static build-up before touching any keys. If at any time during testing your system does not operate properly, contact a qualified serviceperson.
Fan Operation
If your system does not have a G terminal connection, skip to Heating System.
- Turn on power to the system.
- Move fan switch to ON position. The blower should begin to operate.
- Move fan switch to AUTO position. The blower should stop immediately.
CAUTION: Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.
Heating System
- Move SYSTEM switch to HEAT position. If the auxiliary heating system has a standing pilot, be sure to light it.
- Press to adjust thermostat setting to 1° above room temperature. The heat pump system should begin to operate. However, if the Flame icon ( ) and Snowflake icon ( ) are flashing, the compressor lockout feature is operating (see Configuration menu, item 3.)
- Adjust temperature setting to 4° above room temperature. The auxiliary heat system should begin to operate and the Flame icon ( ) will be flashing.
- Press to adjust thermostat setting below room temperature. The heating system should stop operating.
Emergency System
EMER bypasses the Heat Pump to use the heat source wired to terminal E on the
thermostat. EMER is typically used when compressor operation is not desired,
or you prefer back-up heat only.
- Move SYSTEM switch to EMER position. EMER will flash on the display.
- Press to adjust thermostat setting above room temperature. The Aux heating system will begin to operate. The Flame icon ( ) will display flashing to indicate that the Aux system is operating.
- Press to adjust the thermostat below room temperature. The Aux heating system should stop operating.
CAUTION: To prevent compressor and/or property damage, if the outdoor temperature is below 55°F, DO NOT operate the cooling system
Cooling System
- Move SYSTEM switch to COOL position.
- Press to adjust thermostat setting below room temperature. The blower should come on immediately on high speed, followed by cold air circulation.
- Press to adjust temperature setting above room temperature. The cooling system should stop operating.
Configuration Menu
The configuration menu allows you to set certain thermostat operating characteristics to your system or personal requirements. To enter the configuration menu, with SYSTEM switch in OFF position, hold and for at least two seconds. To exit the configuration menu, move the SYSTEM switch from the OFF position.
Step| Press Button(s)| Displayed (Factory Default)| Press
or to select:
---|---|---|---

6| Move SYSTEM switch from OFF| Return to normal operation
- In the run mode, if the setpoint temperature is manually raised by 3°F (2°C) or more above the actual temperature with the TEMPERATURE UP key, and the fast second stage feature is enabled, FA on, the second stage will energize immediately. With FA off, second stage will not energize until the setpoint temperature is 1°F or more above actual temperature for more than ten minutes.
- Select Compressor Lockout CL OFF or ON – Selecting CL ON will cause the thermostat to wait 5 minutes before turning on the compressor if the heating and cooling system loses power. It will also wait 5 minutes minimum between cooling and heating 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 flash the Snowflake and Flame Icons for about five minutes.
- Select Temperature Display Adjustment 3 LO to 3 HI – Allows you to adjust the room temperature display up to 3° 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.
- Select Backlit Display – (Not available on earlier models) The display backlight improves display contrast in low lighting conditions. Selecting backlight ON will keep the light on continuously. Selecting Backlight OFF will keep the light off.
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 pressing and at
the same time when system is switched from “OFF” to “HEAT” position. This also
resets the factory defaults. If the thermostat has power, has been reset and
still does not function correctly contact your heating/cooling service person
or place of purchase.
Batteries
For optimum performance, we recommend replacing batteries once a year with
fresh “AAA” alkaline batteries.
| 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.
| Replace fuse or reset breaker. Turn switch to ON.
Replace door panel in proper position to engage safety interlock or door switch.
No Heat| 1. Pilot light not lit.
2. System Switch not set to HEAT.
3. Loose connection to thermostat or system.
4. Furnace Lock-Out Condition. Heat may also be intermittent.
5. Heating system requires service or thermostat requires replacement.
| Re-light pilot.
Set System Switch to HEAT and raise setpoint above room temperature. Verify thermostat and system wires are securely attached.
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 service person for assistance.
Diagnostic: Set 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 a service person to verify the heating is operating correctly.
No Cool| 1. System Switch not set to Cool.
2. Loose connection to thermostat or system.
3. Cooling System requires service or thermostat requires replacement.
| 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.
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 our 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.
Furnace (Air Conditioning) Cycles Too Fast or Too Slow (narrow or wide
temperature swing)| 1. The location of the thermostat and/or the size of
the Heating (Cooling) System may be influencing the cycle rate| Digital
thermostats normally provide precise temperature control and may cycle faster
than some older mechanical models. A faster cycle rate means the unit turns on
and off more
frequently but runs for a shorter time so there is no increase in energy use. If you would like to increase the cycle time, clip Jumper W-905 as mentioned in the instructions for Hydronic Heating Systems. It is not possible to shorten the cycle time. If an acceptable cycle rate is not achieved as received or by clipping W-905 contact a local service person for additional suggestions.
Thermostat Setting and Thermometer Disagree| 1. Thermostat thermometer
setting requires adjustment.| Thermostat thermometer can be adjusted +/-3
degrees. See Temperature Display Adjustment in the Operation section.
Blank Display and/ or Keypad Not Responding| 1. Voltage spike or static
discharge.| Use the Reset Operation listed above.
