    Thermostat issue

    Great. Thanks for the help. Little tap always might work. Even Han Solo gives a tap to Millennium Falcon. :D

    Thermostat issue

    When I remove the RS1 from the back plate, C/H turns off. So straight replacement for RTS1 then. Correct?

    Thermostat issue

    When I turn off the programmer (British Gas Model UP1) boiler turns off. So I think issue is isolated to thermostat. Also if the issue is the thermostat, can I take the front panel off and replace with front panel from Drayton RTS1 1-Channel Wired Room Thermostat , without any changes on the...

    Thermostat issue

    Hi All. We have Greenstar RI boiler for pressurized system. Our thermostat is British Gas RS1. Yesterday I have noticed boiler is constantly on. Today I have reduced the thermostat to lowest to test it. Despite thermostat is on lowest, boiler is still on. Do you think issue is the boiler...

    Old wiring colours

    I noticed that too. But no clamps. I think it was installed at least 20 years ago.

    Old wiring colours

    Thanks everyone. Junction box is behind the cupboard. I was not able to access from the top. But when I took the bottom part of the cupboard, I was able to open the junction box. I was correct with my guess. But I was lucky that I could reach the junction box.

    Old wiring colours

    Hi specialists. I took the old oven out and took the cables out without taking the picture. Now I need to install new oven, but I need confirmation about the colours. I think blue is neutral, brown / burgundy is live and pink with blue stripe is earth. Am I correct? Thanks

    Swap British Gas UP1 controller to ESI ES3247B Multi Purpose Central Heating Programmer

    Hi All. I am planning to swap the controller for my below system. Would it be easy to swap around? I would like CH1 on thermostat & timer and CH2 only on timer. https://www.amazon.co.uk/ES3247B-Purpose-Central-Heating-Programmer/dp/B01IP3AB70/ref=pd_lpo_1?pd_rd_i=B01IP3AB70&psc=1...

    Danfoss Randall HPV22 22mm 2 Port Valve replacement

    I have another question. While it is black Friday maybe I can invest on a new controller. I want to have different timer and controls for the loft heating, rest of house heating and water heating as I have 3 actuators. Is it possible? Which controller can you recommend?

    Danfoss Randall HPV22 22mm 2 Port Valve replacement

    Our heating comes on when water heating is on. Normally only water heating should come on when hot water is turned on and heating should come on when heating is turned on. I thought it could be wiring issue. So I have swapped around the motors to see the reaction. The one on the right was still...

    Danfoss Randall HPV22 22mm 2 Port Valve replacement

    This is the system. So is it still OK to DIY? Both white actuators are connected to same port on the controller.

    Danfoss Randall HPV22 22mm 2 Port Valve replacement

    Thanks for your reply. It is central heating one. If my tasks list is correct only thing I should worry about is installing the valve correctly without leaks or overtightening the olive. BTW should I use teflon tape?

    Danfoss Randall HPV22 22mm 2 Port Valve replacement

    Hi All. I have 2 Danfoss actuators. I believe one of the valve is broken. I have tested the motors / actuators by swapping them around on two different valves. One of the valves has worked as expected. Other one did not. So I think valve is broken. I have ordered a replacement valve. (...

    Greenstar 24Ri is constantly on

    I have realised one more thing. When I turn other two zone valves to manual, reset works and boiler works. If I leave it with BG UP1 controller and as auto, boiler does not ignite. It seems I will wait until next week and if needed get FPR.

    Greenstar 24Ri is constantly on

    No service at all since we moved in years ago. Do you think heating engineer who will come next week can have a look at it? Or should I get EON gas boiler breakdown insurance which comes with the boiler service?

    Greenstar 24Ri is constantly on

    False remedy. Boiler started to do same thing again. I need to reset the boiler few times to ignite. Something is not right.

    Greenstar 24Ri is constantly on

    You are right Ian. After Terry's question I solved the mystery. Thank you both. Issue is faulty 3rd actuator. Somehow when previous owners built the conservatory, they have added single rad with it's own actuator, instead of integrating into existing heating zone. This rad had Horstman...

    Both HW and CH are whirling with resistance.
