Question about Heating & Cooling
My new Ferroli 31C boiler seems to think it's in otc mode, but it has no outside sensor. Instead of heating the CH water to the set limit, it fires up, raises the temperature a bit, then shuts down, and eventually repeats the cycle. How do I change the OTC settings when a 5-second press on the OTC button doesn't do anything?
This sounds like the boiler is in comfort mode press the eco/comfort button once and eco will be dispalyed on LCD. also check terminal 3 and 4 have no wires on the terminal strip as this is were the OTC is connected to boiler.
