Honeywell LP916C1023 60/80F Ra Return Air Stat
The Honeywell LP916C1023 60/80F RA Return Air Stat is a pneumatic thermostat used for forced-air heating and cooling systems. By detecting the temperature of the air returning to the system via the return air duct, it keeps the temperature at the appropriate level. When the outside temperature falls below the set threshold, the thermostat signals the furnace to start heating the air. From the opposite the same direction, the thermostat causes the air conditioner to cool the air when the temperature increases above the setpoint. The temperature range of this non-programmable, single-setpoint thermostat is 60 to 80 degrees Fahrenheit. It is usually positioned directly on the return air duct and has an easy-to-use warmer/cooler markings design.
