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