12.8.2 Heating

Mode

Protections

1. Outdoor coil Deicing (excluding RH Group)

Mode: Heating, Auto (at heating)

Temp: Selected desired Temp

Fan: Any

Timer: Any

I FEEL: Any

Control function

Protects the Outdoor coil from ice formation by controlling COMP & RV operation.

Scope

This new deicer is designed to operate at extreme temp conditions. The deicing cycle could

be triggered from:

1. OCT temp and time between two consecutive deicing cycles.

2. Detection of ice forming by change of the OCT temp.

Both algorithms adjust the time between deicing cycles to optimize the A/C performance. The

algorithm will automatically increase the time between deicing cycles and reduce the deicing

cycle as needed.
