In a 4 year old house, which had only 1 zone and simple timer. Got plumber to put in two motorised valves, close to where the boiler pipe comes into utility. Plumber never told me there should be a bypass. Currently when timer tells boiler to stop, valve closes and boiler stops firing. Pump keeps pumping to dissipate heat in boiler and has nowhere to go. Boiler thermostat pops due to excess heat.
Was going to get plumber back, then a thought occurred.
Could I put in a time-delay into the circuit before the valve, and another relay between valves and boiler. Thus when timer calls a halt, boiler stops but valve remains open for a few mins so pump can send hot water through house and dissipate residual heat.
See diagram here.
Will this work? Time delay relays will be [broken link removed] and relay before boiler will be normally open, closed when power is supplied.
Note: Receivers refer to wireless thermostat/controller system that sends signals to receivers to indicate when valves and boiler are to operate.
