Lennox 93G35 Thermostat/Freeze

The Lennox 93G35 is a Thermostat/Freeze accessory that is installed on the Lennox HVAC systems with the purpose of avoiding pipe and coil freezing. It works like a mini heater that controls the temperature and when it goes low usually between 29F and 58F it switches on the heating system. This small device can be installed in most home air conditioning systems that use 24V AC power and a 60 Hz frequency. When the temperature is too low, the Thermostat/Freeze automatically switches on the heat source to prevent freeze damaging the HVAC system which may require costly repairs.
