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 2):
The system of  claim 1 , wherein:\n the first sensor data comprises a first temperature sensed by a discharge air temperature sensor configured to sense air temperature in the discharge air duct, and wherein the controller is configured to determine that the evaporator coil is experiencing the first level of freeze risk when the first temperature is below a first threshold; and the second sensor data comprises a second temperature sensed by the discharge air temperature sensor, and wherein the controller is configured to determine that the evaporator coil is experiencing the second level of freeze risk when the second temperature is below a second threshold that is less than the first threshold.
