Robertshaw 500-107 24V Millivolt Wall Thermostat Heating Only

Product Description

The Robertshaw 500-107 is a 24V millivolt wall thermostat designed for heating-only applications. It is built for residential and light commercial heating systems where simple, reliable temperature control is the priority. HVAC technicians and service professionals trust this thermostat for straightforward installations on gas furnaces, boilers, and millivolt heating systems. The 500-107 operates on a low-voltage millivolt circuit, which means it draws power directly from the standing pilot generator rather than requiring a separate power source. This makes it well suited for older heating systems, wall heaters, and gas fireplaces that do not have a common wire or transformer. The unit provides dependable on-and-off control of the heating equipment based on the set temperature. The design is straightforward, with a clear temperature dial that makes it easy for homeowners and technicians to adjust the setpoint. Wiring is simple and direct, reducing installation time on service calls. The 500-107 is a heating-only device, so it is not intended for use with cooling systems or heat pumps. It is compatible with standard single-stage heating controls. Contractors and HVAC installers frequently choose this thermostat as a direct replacement for older millivolt thermostats in the field. Its compact wall-mount form factor fits standard electrical boxes and mounting locations. Robertshaw is a well-established name in the HVAC controls industry, known for producing reliable thermostats and gas controls for decades. The 500-107 continues that tradition by delivering consistent temperature sensing and switching performance in a durable, no-frills package that holds up in everyday residential service environments.
