Hello All, Happy New Year!
I am trying to complete connecting up a Espar Hydronic D5W S. The prior owner had started it but not yet completed it. Unfortunately, I don't have the documentation for the controller board (pics attached). It looks almost complete. The wiring from the Espar to controller is connected. It appears that only the fuel pump and battery need to be connected. The Espar documentation indicates brown and green from the D5W go to the fuel pump. The brown and green on the control board are connectors labeled "MP" (Maybe Motor Pump?)
There is no external controller/thermostat for the unit. The controller has 10 connections for 2 zones (white connectors near top of pic). I am hoping I don't need a zone thermostat and that I can hook up the fuel pump and battery and away we go...
I have an Espar AirTronic heater and it does indeed have an external thermostat. I know that when I turn the air heater off, the unit goes through a cooling off cycle. You definitely shouldn't turn the battery power off prior to letting the unit go through the cooling cycle. Is that the same for the Hydronic? If so, I will have to make some connection to a Zone 1 pin to control on/off while leaving battery power on to the D5WS.
Any input would be appreciated.
