SOURCE: I have a Honeywell Thermostat CM67NG The flame

You may have a broken thermostat wire. Disconnect the wires from the thermostat and please note what colors are hooked to which terminals. Cross the R and W wires and see if your heating system turns on. If it does not, you have a broken wire or bad connection at the heating system. If it does start, you have a bad thermostat or bad connection at the thermostat.

Vailant ecotec plus 837 - Water pressure and temp is too high


Pressure inside the tank will rise along with the water temperature. As the water inside cools the pressure will wane until the heating element turns on and reheats the water with a subsequent rise in pressure. Running the hot water at the same time will draw heat energy from the boiler and lower the internal temp and pressure as well.
