Ravenheat CSI 85 CH water suddenly running greatly hotter.
Does ignite on/off on CH thermostat/potentiometer manual control knob - but CH water temp. does not reduce by this control knob (as it did). With high temp, water pressure can increase from 1.5bar to near 3bar - pressure relief valve releases water. Overheat cut-out does not intervene - water not that hot.
? Thermistor/sensor fault. ? fault in thermostatic controls on electronic printed control board ?.
