My mates heating & hot water system setup, he has got a combi boiler downstairs & a hot water tank & a smal res tank in the airing cupboard. Off these there is x2, 2 port actuators & 1 pump.
The pump & 1 of the hot water actuator needed replacing. Done that but when the heating & hot water is switched off by the timer controller unit the pump keeps running. Is this correct ?
The actuator that we replaced for the hot water is connected through a thermostat built on the side of the hot water tank which stops the flow when the water is up to temp in the tank.
The wiring is a bit of a mess (looks like it was designed by NASA!). The wires off the new actuator are brown(live), blue(N), grey(NC), orange(C), white (which isnt used, i think 22mm pipes), gr/yel(E).
Anyone got any ideas ?
