How does this connect to the bottom of the contactor? My old transformer has 2 wires (white and red), the new one has three wires (black, orange and red)

Written on 6/4/2019 by Guest

I have a Hayward HeatPro heat pump pool heater model No. HP21002, that was not operating. I replaced the Heat Pump Control Board, the Thermostat Interface board, the Transformer and the Temperature Sensor, and I am receiving the error code OP in the display. So, obviously, I still have not found the problem.

Were these instructions helpful?
