Robertshaw 7-Day Programmable Thermostat 2H/2C - RS9220

Restore accurate room-temperature control with this Robertshaw 7-Day Programmable Thermostat 2H/2C - RS9220. This wall thermostat monitors indoor temperature and cycles compatible heating and cooling equipment on and off to maintain the set point.

RS9220 is a thermostat selected by system type, staging, voltage, and terminal configuration rather than by appearance alone. Replace it when the original control drifts out of calibration, stops responding correctly, or no longer maintains a steady room temperature.

Compatibility: This is an HVAC control matched by system type, heat/cool staging, voltage, and terminal layout rather than by appliance model number alone.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Inaccurate room temperature, short cycling, no call for heating or cooling, or unresponsive controls.
• Visible/Sensory Cues: Blank or erratic display, worn buttons, inaccurate temperature readings, or mismatched terminal labels during replacement.

Pro Tip: Photograph the original thermostat wiring before removal and verify terminal names and system staging before installing the new control.
