When switched on, the Antifreeze option will close its contact connected to the brown wires when the measured temperature drops about 2°C below the temperature set with the dials (R_SW1, R_SW2, and R_SW3). When the brown wires are connected to terminals 16 & 17 in the PCGO-V3 and PCGO-V4  (connections 23 & 24 on PCGO-TA) pool control boxes (External pump control) the pump will start when the contact of the antifreeze option closes.

When the measured temperature rises about 2°C above the temperature set with the dials (R_SW1, R_SW2, and R_SW3) the contact of the antifreeze option will open and the pump will stop.

Example: 

The antifreeze option is set to 4°C (R_SW1 set to 4, R_SW2 set to 0, R_SW3 set to 0). It will start the pump when the measured temperature drops below 2°C and stop the pump when the measured temperature rises above 6°C.
