Hello,
I recently moved into a new house with ecotec 415 gravity fed system. not sure if working initially but I have since installed a nest thermostat. I have been over the wiring several times and all seems to be fine. I hear the thermostat click when HW and CH demands are triggered. I hear the 3 port valve spin when CH triggers.
my problems are as follows:
with no demands from thermostat, boiler shows tap but not firing.
with CH only, as above.
with HW only, tap and radiator show, boiler fires to HW.
with CH & HW, boiler fires to CH, tap and radiator showing.
I think some settings on the boiler may be incorrect, anyone have any suggestions?
