Mode of Operation

The SC5010 is a programmable, manual or auto changeover, single-stage heat, and single-stage cool thermostat. It functions with air conditioning, heat pumps, gas, oil, or electric heat systems. The thermostat activates the heating appliance when the room temperature is below the set heat temperature (by the differential temperature) and the red indicator light (configurable) on the thermostat will light. The SC5010 will stop outputting and the red light will turn off when the call for heat has been satisfied. With heat pumps, the thermostat will not let the compressor come on for 4 minutes after it turns off. This protects your compressor. When the room temperature is greater than the set cool temperature (by the differential temperature), the cooling device is activated and the green indicator light (configurable) on the thermostat will turn on. The SC5010 will stop outputting and the green light will turn off when the call for cooling is satisfied. The thermostat will not let the compressor come on for 4 minutes after it turns off. This protects your compressor.

The SC5010 has five possible operating modes: OFF, Heat, Cool, Heat & Cool, and Program mode. In off mode, the thermostat will not turn on heating or cooling devices. The manual fan can be turned on in all operating modes using the fan button. In heat mode, the thermostat controls the heating system. In cool mode, the thermostat controls the cooling system. In heat & cool mode, the thermostat controls both the heating and cooling systems. In program mode, the thermostat will automatically be controlled by the set program. Program mode can function with heat mode, cool mode, or heat & cool mode. The clock display alternates with the set temperature display for heat & cool modes.

The programmable fan feature can be used to run the fan during occupied periods. The program schedule can be overridden by changing the set temperature (up or down button). This puts the SC5010 thermostat on a 2-hour temporary hold. After 2 hours, it will automatically return to the program schedule. The SC5010 also has a button lockout feature. This enables the thermostat to be set to the proper mode and temperature and locked so it cannot tamper with.
