To Remove Existing Thermostat ELECTRICAL SHOCK HAZARD – Turn off power at the main service panel by removing the fuse or switching the appropriate circuit breaker to the OFF position before removing the existing thermostat. 1. Turn off power to the heating and cooling system by removing the fuse or switching the appropriate circuit breaker off. 2. Remove cover of old thermostat. This should expose the wires. 3. Label the existing wires with the enclosed wire labels before removing wires. 4.
To Install Thermostat (continued) 2. To remove cover, insert and twist a coin or screwdriver in the slots on the sides of the thermostat. 3. Put thermostat base against the wall where you plan to mount it (Be sure wires will feed through the wire opening in the base of the thermostat). 4. Mark the placement of the mounting holes. 5. Set thermostat base and cover away from working area. 6. Using a 3/16” drill bit, drill holes in the places you have marked for mounting. 7.

Configuration Mode The configuration mode is used to set the SC2210 to match your heating/cooling system. The SC2210 functions with up to 3-stage heat pump systems. To configure the SC2210, perform the following steps: 1. Slide the Mode switch to the OFF position. 2. Remove the cover of the thermostat by gently pulling on one of the corners. 3. Simultaneously hold the SW5 and SW6 buttons in for 5 seconds while the SC2210 is in OFF mode. 4. Press the or button to change settings within each screen. 5.
4. Temperature Differential – Stage 3 – (1°F to 6°F) (0.5°C to 3.0°C) – Set the number of degrees between when stage 2 turns on and stage 3 turns on. Press the or button to set differential value. Press the SW6 button to advance to the next screen. 5. Staged Off Outputs Select whether the outputs for heating and cooling are staged off independently or are satisfied simultaneously. 1 = Economy Mode – Outputs are staged on and off in accordance with set point and differential.
10. Filter Check time (300-800, – – –) Set Fan Run Time (in hours) when Check Filter is displayed or set to – – – to disable. Press the or button to select. Note: After exiting configuration mode, to reset filter counter to zero and clear filter warning, press the and button simultaneously for 5 seconds. Press the SW6 button to review settings. Slide the Mode switch to Heat or Cool to exit configuration.
LED Indicators There are three LED indicators located on the front of the thermostat.
Cool Test 1. 2. 3. 4. Slide Mode switch to Cool mode. Adjust set temperature so it is 5 degrees below room temperature. Air conditioning should come on within a few seconds. Adjust the set temperature 2 degrees above the room temperature and the A/C should turn off. There may be a fan delay on your system. Note: There is a five minute time delay to protect the compressor after it turns off. To temporarily bypass the five minute delay, slide the Mode switch to OFF for 2 seconds and then back to Cool.
(Testing the thermostat continued from Page 23) Fan Test 1. Slide Fan switch to On position. 2. Indoor fan turns on. 3. Slide Fan switch to Auto position. 4. Indoor fan turns off. Auto On Auto On Mode of Operation The SC2210 is a multi-stage, heat pump thermostat. The SC2210 can use 24 VAC or batteries as a power supply. The SC2210 can be hardwired and have no batteries installed in the battery compartment. It can also run on battery power only.
Troubleshooting Symptom No display System fan does not come on properly Thermostat turns on and off too frequently Fan runs continuously Room temperature is not correct ROOM displays filter displays Auxiliary heat not on soon enough Problem not listed above Remedy For Hardwired Installation Check for 24 VAC at thermostat; display is blank when 24 VAC is not present For Battery Installation Display is blank when batteries are drained or installed incorrectly Verify wiring is correct Adjust temperature dif
