Not sure if this should be posted in electricians forum so apologies in advance.
I am a qualified plumber.
This is in my own house and will be implemented by a qualified electrician under my instruction.
I have a thermal store designed and installed by myself.
Off of the thermal store I have a radiator circuit, flow and return,which takes heated water from the store independent from any control of the boiler and other heat sources.
Demand for this circuit comes from a thermostat that simply switches on a pump on the flow side of the radiator circuit
I have an issue with gravity heat leak on this circuit, i.e. when there is no demand from the radiator circuit thermostat hot water will still circulate around the circuit due to gravity, effectively leaking heat from the thermal store and unnecessarily heating rads etc.
My solution is to put a 2 port valve between the thermal store and the pump that opens when the pump is switched on by the thermostat.
Effectively in series with the pump, simply connecting the live neutral and earth to switch the valve open.
However my honeywell 2 port valve has 5 wires and all the wiring diagrams ive seen instruct me for y plan or s plan etc, when I just simply need it to open when current detected and closed when not.
Is this possible?
many thanks.
