Carrier HH22HB077 Temperature Actuated Switch F-80° F-10° F

The Carrier HH22HB077 is a HVAC temperature control switch for the regulation of heating and cooling. It operates on the basis where it has a set temperature range, determines whether or not the surrounding temperature is within the range and either starts or stops the equipment. In colder climates, if the temperature drops below the set minimum the switch turns on the heating system to warm the house. if the temperature goes up beyond the upper limit the switch turns on the cooling system to maintain a favorable climate. This control assists in protecting the system and keeping the temperatures constant in order to enhance the energy use in your HVAC system.
