One remote temperature sensor can be installed indoor or outdoor and connected to the thermostat by a maximum cable length of 100 meters (300 feet). Terminals +, S and – on the terminal block allow connection of the remote sensor. The thermostat must have 24 VAC Common connection to terminal C for the remote sensor to operate. The remote sensor can be enabled or disabled in the Installer/Configuration menu, item 25. When remote sensor, Remote, is Remote selected Off (factory default), no remote sensor is enabled. When remote sensor is selected On, the next step is to select the remote as indoor, Remote In, or Remote In outdoor, Remote Outdoor. If the Remote Outdoor remote is selected as Remote In, an Remote In additional step will be to select if the temperature shown on the display will be from the thermostat, LS On, or the remote sensor LS On Ls Off. Ls Off In normal operation, when a remote sensor is enabled the time digits of the display will alternate between the time and the remote temperature for three seconds each. Above the remote temperature will be Remote, Remote for indoor sensor or Outdoor Remote, Outdoor Remote for outdoor sensor. If the remote sensor is an indoor sensor and the local display has been disabled, the temperature displayed as the room temperature will be the remote sensor temperature. Sensing Range: Outdoor temperature range is -40 to 140oF Indoor temperature range is 32 oF to 99 oF
The thermostat is designed to receive the temperature of the indoor remote sensor and average or weight, it with the local sensor in the thermostat for each program period. The averaging will be active only when the local sensor and the indoor remote sensor are both functional and enabled in the Installer/Configuration menu. When the thermostat is in the Set Schedule mode, the weight of the indoor sensor will be shown in the current temperature digits of the display. The weight will show as A2 (average A2 and default), H4 (high) or H4 L1 (low). Pressing the
Weight of Remote Reading
When in view schedule mode the weight of the indoor remote sensor will be shown in the left actual temperature digits designated as A2 (default for average weight), H4 (high weight) or L1 (low weight). The period (Morning, Day, Evening, Night) will also be shown to the right of the weight value in the actual temperature digits. When in view schedule mode, press and keys at the same time to sequence the indoor remote temperature sensor weight from A2 to H4 to L1 and back to A2 for each of the program period times for each day. (The H4 weight is twice the weight of A2 and A2 is twice the weight of L1).
When Remote In is selected (with Remote selected to On), press key for the display to indicate the status of the local sensor LS On (default for thermostat local sensor operation-al). The and keys will toggle the function and display from LS (shown in actual temperature digits) and On (shown in clock digits) to LS OFF to designate the local sensor is disabled. The local sensor may be disabled only if the indoor remote sensor is enabled and functional. If the indoor remote sensor is disabled or not functional, the local sensor will automatically enable and display in the run schedule mode. The actual temperature displayed in the run mode is the mathematical weighted sum of the two temperature sensors – local and indoor remote. (Outdoor remote sensor is not used for this computation). If the remote sensor is absent or not enabled then the actual temperature will be as measured by the local sensor.
Note:When thermostat is reset, 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 andC (do not short them together) and removing batteries for 2 minutes. After resetting the thermostat, replace C 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.
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. 4. Loose connection to thermostat or system. | Replace fuse or reset breaker. Turn switch to ON.Replace door panel in proper position to engage 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. Heating system requires service or 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 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 HVAC service person to verify the heating is operating correctly. |
No Cool | 1. Cooling system requires service or thermostat requires replacement. | Same 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 out from under 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. Thermostat thermometer setting requires adjustment. | The thermometer can be adjusted +/- 4 degrees. See Temperature Display Adjustment in the Configuration Menu section. |
Furnace (Air Conditioner) Cycles Too Fast or Too Slow (narrow or widetemperature 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 slow cycle in the Configuration menu, step 7 (heat) or 8 (cool). If an acceptable cycle rate is not achieved, contact a local HVAC service person for additional suggestions. |
Forgot Keypad Lockout Code First item in Configuration Menu is not SS1 or HP1 | Press the menu button (button will disappear) and hold in for 20 seconds. This unlocks the thermostat. Earlier model of thermostat refer to 37-6814D. |
