Hi, On my boiler I have a Teddington TB8 on/off switch combined with a hot water limit thermostat (see picture). The male spade connector on the left of this picture is labelled COM and the on on the right it is "Break on Rise".
Please can someone help me understand how it works. Clearly the sensor is a thermocouple device. There appears to be a single heavy duty, uninsulated copper conductor returning to the back of the switch above the Break on Rise male spade. Is this really a copper conductor or are there smaller wires inside? In general, how does the device work. For example, what signal does it send to the system?
My problem is the water in the tank is exceptionally hot even on the lowest setting. Please can someone help me understand how it works. \
