Claim 14:
15. A heating, ventilation, and/or air conditioning (HVAC) system, comprising:
an outdoor ambient sensor configured to detect a temperature of an ambient environment of the HVAC system;
an outdoor coil sensor configured to detect a temperature of an outdoor coil of the HVAC system, wherein the outdoor coil is configured to direct a refrigerant therethrough; and
a controller configured to:
operate the HVAC system in a first mode to transfer heat between the refrigerant and an air flow via the outdoor coil when first data from the outdoor ambient sensor and second data from the outdoor coil sensor are received by the controller, wherein the first data comprises the temperature of the ambient environment, and the second data comprises the temperature of the outdoor coil; and
operate the HVAC system in a second mode, different from the first mode, to transfer heat between the refrigerant and the air flow via the outdoor coil when the second data from the outdoor coil sensor is received by the controller and the first data from the outdoor ambient sensor is not received by the controller.
