Hi All - can anyone please help me?
I have a Y plan heating system with the boiler, wiring centre and three port valve located in the basement of the property. The hot water cylinder is located on the first floor. A three core cable is running from the wiring centre to the cylinder thermostat and linked to the common, no demand and heating required terminals of the thermostat.
At some point a second cylinder has been added next to the original to increase the volume of stored hot water. The new cylinder does not have a cylinder thermostat fitted and is therefore only being controlled by the thermostat on the first cylinder.
I would like to ensure that each cylinder has thermostatic control but would like to link this via the existing wiring to the three port valve. I've searched on the internet but have been unable to find a solution.
My thoughts so far involve using thermostats linked to two port valves, with a relay to ensure they are both satisfied before sending a signal to the wiring centre. (See attachment of rough schematic)
I would appreciate any thoughts on this (or better solutions).
Thanks
James
