The air conditioning system should turn on within a few seconds. NOTE: When in the COOL mode (or HEAT for single stage heat pumps), once the thermostat turns off, a built in 5-minute delay prevents the system from turning on again. This protects the compressor. No additional time delay relay is required. 3. Put the COOL-OFF-HEAT-EM switch into the OFF position. The air conditioning system should turn off. 4. Put the COOL-OFF-HEAT-EM switch into the HEAT position. 5. Press the > button until the temperature setting is at least 3 degrees above room temperature. The heating system should turn on. The fan may not turn on immediately, depending upon the fan delay built into the furnace. 6. Put the COOL-OFF-HEAT-EM switch into the OFF position. The heating system should turn off. The fan may continue to run for a short period of time. 7. Put the FAN: AUTO-ON switch to the ON position. The blower fan should turn on. 8. Put the FAN: AUTO-ON switch to the AUTO position. The blower fan should turn off. COOL-OFF-HEAT-EM COOL-OFF-HEAT-EM FAN: AUTO - ON COOL-OFF-HEAT-EM FAN: AUTO - ON 7 Changing Fahrenheit (F) to Celsius (C) The thermostat is preset to display the temperature in degrees Fahrenheit. You may change the display readout to Celsius if desired. 1. Move the manual switch marked “F” (Fahrenheit) and “C” (Celsius) located at the top center of the circuit board to the desired setting. (see page 5) 2. Press RESET button located lust below the LCD display to register the change. The display will change to show the temperature in your desired temperature scale. To return the thermostat to its original setting, repeat steps 1 and 2 above. LED Indicators The LED indicators are used to indicate system activity. The AUX indicator illuminates during a call for second stage heating. The auxiliary stages are used to maintain comfort during extremes in weather conditions. If the AUX LED is illuminated too frequently during periods of moderate temperature, check the differential settings (page 6). The CHECK indicator is used to monitor system status. If the CHECK indicator is illuminated, call your local HVAC service provider. The EMER indicator is illuminated only when the system switch is moved to the EM, emergency heat position. The EM position is used only when the primary stage of heat is not functioning or requires service. Troubleshooting Symptom Remedy Thermostat does not turn on system. Check Wiring (see INSTALLATION). Check fuse. Replace with 2 amp fuse if fuse has opened. Thermostat turns on and Increase Temperature Differential off too frequently. (see DIFFERENTIAL). System fan does not Move fan option switch to either operate properly. gas or electric, to match system (see INSTALLATION). Thermostat does not display proper room temperature. Check “F” Fahrenheit /”C” Celsius switch located at top center of circuit board for proper position. If a new selection is made, press “RESET” button located directly below LCD display. 8 If problems with thermostat cannot be solved, call: Technical Support: 608-257-8801 Monday-Friday 7:45 am-5:00 pm CST 9 Wiring Diagrams The following is just a sample of the most common types of HVAC systems.
