The only problem was that the downstairs stat controlled the upstairs circuit and visa-versa. That has now been changed as part of other work , see thread https://www.diynot.com/diy/threads/wrong-zone-valve-actuator-head.618949/ Thanks for the help

That would have been a good idea had I not already replaced the existing wiring centre with a slimmer one. I had to cut the architrave on the inside of the frame away to fit the new box. Your idea would have been better solution using the box suggested above but jobs is done now and all seems...

Job done. Thanks for the help

Sorry, I don't see the relevance of the Regin socket to drain(ing). I don't intend to alter the wiring to keep the existing actuator, I will replace it. I'm just concerned that someone else has tried. The original installer of the wrong head may have done something to the connections to try and...

First picture is of cable extension to HW zone valve from wiring center. Note white wire from valve (bottom connector) becomes pink wire to wiring center (top connector). Second picture is wiring center which, as a sparks, I shake my head at. Getting a better picture of the wire layout will...

Am I right in thinking the Honeywell V4043H 2 port valves open from fully closed to fully open through approx 45 degrees of movement of the valve spindle i.e. a quarter turn from fully open to fully closed. Does a similar bodied Honeywell 3 port valve (V4073??) have the same range of movement...

Is there any good reason for fitting a 3 port Honeywell zone valve head part no. 40003916-003 on a 2 port Honeywell zone valve (see photo). I believe the 2 port valve should have an actuator/head part no. 40003916-001 fitted. It would appear the only time the valve closes with this...

Turns out the upstairs stat controls the main bedroom, its ensuite and other bedroom radiators, whilst the downstairs stat controls the landing, bathroom (upstairs), hallway and all downstairs radiators. All the rads have thermostatic valve heads except the hall and main bedroom. Is this...

Thanks for the link. Strangely, after seeing you reply I found the same link by Googling for 'upstairs and downstairs thermostats on an splan system'

I'm aware of S Plan systems, i.e. whole house CH as one zone with HW as another zone, but have not come across the + option. Does the + part just mean that one zone, typically CH, is split into 2 or more zones? Did a Google search for Splan+ (and all variations of the spelling) but couldn't...

I've only casually looked at the system so far and have only seen one zone valve which is close to the HW tank but don't yet know if its for the tank. Hopefully once identified I can just swap the roomstats or zone valves switched lines over in the wiring centre once I've found it.

My sister recently moved into a house that has a gas central heating and hot water storage system (not a combi boiler). The system has an upstairs room thermostat in the main bedroom and a downstairs thermostat in the hall. All the radiators have thermostatic rad valves except those in the main...

Can anyone identify the manufacturer of the uPVC door flag hinge in attached photos please? I believed it was installed around 2005.

There is draft and external noises coming through my uPVC front door. The draft and noise is only noticeable in the middle section between the door hinges. Pushing the middle of the door toward the frame on the hinge side stops the draft and noise. The door appears to be slightly bowed away...
