Abstract:
According to certain embodiments, a system comprises a controller and an HVAC system with components comprising an evaporator unit comprising an evaporator coil, an indoor fan, and a discharge air duct and a condenser unit comprising a compressor, a condenser coil, and an outdoor fan. The system is configured to determine that a first or a second level of evaporator coil freeze risk is present and to communicate an instruction to the HVAC system with a first or a second action to counteract the freeze risk. For example, in certain embodiments, the actions comprise changing the indoor fan speed, changing the compressor speed, and changing the outdoor fan speed.

Claim (Index 14):
The controller of  claim 10 , wherein the second action comprises operating the compressor at a reduced speed and wherein the controller is further configured to:\n determine, on a periodic basis, whether the compressor has been operating at the reduced speed below a recommended reduced speed for a first pre-determined amount of time; in response to determining that the compressor has been operating at the reduced speed below the recommended reduced speed for the first pre-determined amount of time, send the HVAC system an instruction to increase the compressor speed for a second pre-determined amount of time; and in response to determining that the second pre-determined amount of time has elapsed, send the HVAC system an instruction to resume operating the compressor at the reduced speed.
