Understand the Indoor Coil Anti-Freezing FunctionUpdated 2 days ago

The article explains the indoor coil anti-freezing function for Vertex Ducted Central Split (DYC-18) systems. 

This function prevents the unit from running at low evaporating temperatures, as well as low suction superheat. The function utilizes the T2 (indoor coil temperature) sensor to determine whether the indoor coil is freezing or not. 

The function will activate when the T2 sensor detects the temperature is less than 32°F (0°C). The compressor will turn off when the function activates. 

The function will deactivate when the T2 sensor detects the temperature is more than or equal to 43°F (6°C). 

The function is valid in both 24V and RS-485 communication mode.
