Hello, I have my Pentair MasterTemp 400 connected to my Hayward Prologic board via the 2 wire method (18AWG per spec)
Fireman Switch to the Heater1 relay on the Prologic
I have enabled heater1 in the configuration menu on the ProLogic. I press heater1 and no light illuminates and it says Gas Heater Auto Control and no response from my MasterTemp 400.
When I remove the 2 wires and connect the jumper at the fireman switch the MasterTemp 400 immediately works. I used a multimeter at the Prologic to ensure I am receiving voltage and continuity. I am indeed getting around the 24VAC per spec and continuity.
Any ideas on resolving would be greatly appreciated
