Essential Info
With the comfort, convenience, and efficiency features that homeowners and contractors want, the RS4220 thermostat provides custom program options in an economical and value-packed thermostat. Installation is fast and easy with the quick-connect wiring feature. The thermostat includes auto changeover to automatically switch between heating and cooling for constant home comfort. Keep the fan circulating to maintain optimal air circulation between demand cycles for improved comfort with minimal energy use.
Its big, bright backlight makes viewing and setting the temperature easy and even includes a nightlight option. Adjustable temperature differential and upstaging provide for a full selection of parameters to deliver maximum comfort or energy savings. High and low setpoint limits protect the heating and cooling systems by limiting temperature settings. Low temperature freeze protection automatically turns on the heat when temperatures drop below 41 degrees F to prevent pipes from freezing.
