Fan/pump controller set up for OptiClimate Chiller

A Fan/Pump controller in combination with a Fan/Pump box is used to turn the pump on/off and control the fan speed of the chiller.

The controller receives 2 signals from 2 sensors: 1 temperature sensor to determine the water temperature in the system and a start sensor to determine whether the compressor in the Opticlimate is on/off.

The start sensor controls the pump and the temperature sensor controls the speed of the chiller's fans.

Without this fan pump control, the fan and pump will run at 100% 24/7.
