when the HW is on and the valve is energised the rads stay cold but when the HW is no demand and the valve runs back then the hot water slowly goes to the rads (the pump is off), so with the valve at default the port is open to CH so the water can circulate, think i need another shut off in the...

The main board will only accept a 3 wire diverter valve see this photo of a similar one on fleabay http://www.ebay.co.uk/itm/WORCESTER-HEATSLAVE-4-RELAY-CONTROL-PCB-87161463110-/180558821026?pt=UK_Home_Garden_Hearing_Cooling_Air&hash=item2a0a24f6a2

Heatslave 15/19 on front panel not sure of age (old) we bought a house that we have been renovating (major works) since last Nov so not really been using it and only noticed this problem the other day as we wanted some hot water. The valve actuator is a Drayton ZA3 and looking on the web that...

When the valve runs open it heats the hot water only , switching on the CH as well it runs back to the non powered position and the CH heats as well So is that a programmer fault giving the wrong signal to the valve at the wrong time or the actuator at fault. The actuator is the 3 wire type with...

Have a Heatslave 15/19 and have a problem in that when the 2 channel programmer is set to hot water only (CH off) some of the rads still get hot. The diverter valve (Has a Drayton ZA3 actuator on it) runs to the HW position when demand for HW is given, when the demand stops the boiler goes off...

This is the mixer http://www.gainsboroughshowers.co.uk/upload/Product%20Images/GS400%20BODY%20EXPOSED%20LR.jpg Not had much chance to investigate as am at work at the moment, so only managed to quickly flip off the centre cap and remove temp adjustment knob. there is a centre shaft for the...

Using all existing plumbing from pump which worked fine with the old manual mixer valve that have now replaced with the GS400. Hot supply is HOT so no problems there. Convinced it is the mixer at fault (or just set low from factory)

The hot/cold connection are correct and last night I took the temp control knob off but no adjustment can be made, looks the end stop is internal. So will have to strip it down or send it back as not fit for purpose!!!

Have just installed a Gainsborough GS400 thermostatic mixer shower but the temp is not hot enough. It is supplied from a power shower pump so both pressures for hot/cold are the same. have even tried reducing the cold flow by closing the isolator off a bit but still only warm water. Guess its...
