heating controls

Hi all, Long time follower of the forum; first time poster! I noticed recently that when my central heating is OFF (in other words, turned off at the control module [where you programme days/times for auto start etc.]), that the boiler still kicks into life, when I set temperature on my...

Hi All, I am considering installing a Vaillant Arotherm Plus 7kw heatpump in my house. Does anyone know if the Arotherm Plus 7Kw includes a controller unit (wiring center)? I previously lived in Denmark and Vaillant supplied a seperate VWZ AI Controller and this could be paired with a Vaillant...

Hi! I have a Salus ST620RF Thermostat which is used as an on/off switch for a water pump for our radiator water loop when the water is being heated. Normal behaviour is that we use it as a manual switch (Manual Setting) and manually flick it between on and off as we need the radiators running...

Evening all, I've just bought a Drayton Wiser Kit 1 to replace my EPH Controls (RF1A-OT) and just want to clear something up with the wiring. Here is the current wiring setup: And here are the instructions for the Drayton Wiser Kit 1 (Combi Potterton boiler) Am I missing anything from the...

Hi All, I have a Vaillant ecoTEC 637 plus, likely fitted ~2017 mounted as a system boiler, single zone, with a separate water tank for DHW. The thermostat is a Salus RT500 wired via the 230v RT connection. There is also a Drayton scheduler. (Small parenthesis: It is also a classic case of...

Danfoss SET1E heating timer, it is showing red LED light but LCD is blank for all positions of grey switch on the right, it shows nothing. Does not appear to have reset button underneath. Ideas how to get LCD showing again/ or a fix.

I've got a static caravan with a Morco GB24ErP combi boiler, which has a built in tappet style timer for CH. I wish to add a Drayton Wiser system so as to have better control and more importantly be able remotely turn heating on when we are getting close to our holiday home. The boiler has a...

Hello, We have a robust, relatively new hot water & central heating system including a hot water tank and a system boiler. We live in a fairly rural location and unfortunately experience power cuts quite regularly. In January this year, we had a power cut which resulted in a failure in our...

Sorry, I really have spent about an hour looking online for the answer and just can't find anything. Boiler = Worcester Greenstar 28i (dial/timer in the middle) Old thermostat = Siemens Landis & Staefa RA02 New Thermostat = Hive single chanel active heating. The old thermostat is in another...

A year ago alongside a new combi boiler we got a new room thermostat/timer, Center RF 340017, which I believe is a rebranded Honeywell. Sometimes when pressing a button on it (e.g. to manually change the temperature), the display switches off and after a few seconds asks to set the time...

Where can I buy five core cable in which the conductors have the same colours as most central heating two-port zone valves (i.e. grey, orange, blue, brown, earth). Thus is so that I can re-route some cable runs. I know I could use five core with other colour schemes, and I can get plenty of...

Hello, we have the centaurplus c27 and it currently has no power. I am trying to establish if the problem is the central heating programme or the power supply. I have removed the until from the wall and replaced the battery. Does anyone know if the unit needs to be back on the back plate in...

The title says it all. I've had the same oil burner in the house from when it was built. It's regularly serviced and works brilliantly but it does have an old timer system that I'm desperate to replace. This is the current setup. A 24 hr dial timer with a separate thermostat switch. The...

Hi, Wondering if some kind person on here happens to know whether my Honeywell cm907 thermostat can be swapped out for a Nest E thermostat? Currently I have the honeywell connected to my gas combi boiler and the thermostat controls the heating alone. The screen on the honeywell has failed (a...

My mum has a Worcester Bosch gravity fed boiler with an Altech ALTHC001 control panel. For some reason the 1 hour override buttons for heating and water don't fire up the boiler. They light up when pressed, but nothing happens. The manual doesn't really shed any light on this. Can anyone help?

I've bought my HIVE in the black Friday sale last year and have been waiting for the local plumber to install but he keeps fobbing me off.... so can anyone advise me on how to wire this up.... I've been through all the usual tutorials and can't make sense of them because they're all different...

Good afternoon. I’m after some confirmation. Just changed over from an old rotating Honeywell room thermostat to a new WIFI digital one. It’s connected to my Potterton gas boiler via the switch unit underneath. (see pics). I’m aware that I have to leave the ‘CH’ slider to constant ‘ON’ to...

Hi, hope someone is able to help. I’ve recently turned my heating on and read the instructions for the Siemens RDJ 10 thermostat repeatedly so they’re no stuck in my brain(!) I’ve set it so the temperature should be 20.5 degrees, problem is it’s only getting to 18. I don’t understand why My...
