SPDT RESISTANCE HEAT THERMOSTAT FOR

This product is a 20856 SPDT RESISTANCE HEAT THERMOSTAT, for Heat Pumps with 1/64 F Differential. Its maximum wattage is 63 Watts and its voltage rating is 125.

Protect your valuable heat pump or air conditioner from heating and or cooling too much with a Robertshaw 20856 SPDT Resistance Heat Thermostat for Heat Pumps -1/63F 5F Diff. 30 Cap. 3/8 X 6 Bulb with Knob. Designed to replace standard heat pump thermostat, it features variable temperature differential switch and is intended for heat pumps or air conditioners with a capacity between 2,600 and 15,500 BTU/HR.

Designed for indoor mounting, the 20856 SPDT resistance heat thermostat is a low voltage heat-only thermostat with an operating range of 14 to 32 degrees Fahrenheit. It is also perfect for replacing old or damaged thermostats used on flooring, cooling coils and water heating applications.

When a change in temperature occurs on one side of the RTHT20856, the other side will either turn off the heat or open a damper. The SPDT RESISTANCE THERMOSTAT, 20856, is used with a heat pump and the setpoint can be set to: High-63°F to 5°F. Low-0°F to 30°F. There are two (2) terminal connections. The controls are balanced with a difference of 4°·A/W or less.

This is the SPDT thermostat for use with heat pumps for application where you have a steaming coil and want air flow for defrost applications. It has a -1 to 5 degree temperature differential and will handle an input of 10 amps. It has a 30 amp continuous rating and a 63 amp interrupting rating. The maximum voltage that may be applied to this thermostat is 250 VAC at 50/60 cycles. This thermostat comes with white knob assembly...

The 20856 SPDT heat pump thermostat is used on 1 to 1/2 HP heat pumps. The 3/8" diameter terminal studs accept 24 to 18 gauge two conductor wire. Knob has positive detents at 80 and 90 degrees Fahrenheit without any overextension. Also known as part number 20731 (dual duct type) 20828 (single duct type).

The 20856 is a SPDT thermal protector thermostat. It limits the temperature by stopping the flow of electricity.
