So, now that I have it all working, I am considering completely mucking it up again by adding a hive/nest controller ;) What do I need to consider to do this, is it as simple as connecting the cabling in the timer to the terminals on the hive backplate, and linking out the thermostat?

Thank you all for your help, it appears to now be working (fingers crossed) and I have managed to draw my system schematic so should be able to identify any issues in the future too!

Brilliant, yes i thought that i would be able to, hence why i had disconnected them to do a continuity test. Thank you again, and for your speedy response, i'll try it later tonight and report back!

Thank you for the detailed response, and the link provided. As you state it was an error on the 2/3 port valve. When im looking at the thermostat wiring, is there an electrical method to see which is which, i.e if the heating is on, will i see a voltage across the switch live, as i assume the...

Thanks for the responses, Is there any pictures or further details i can provide to help identify any of the system? You are right, it is 3 port, typo on my part, what i want to be able to do is identify what all of the conductors are doing, as i am aware that the colours used for systems are...

Existing Setup

Hi, I'm currently having issues with my central heating system (oil boiler) following replacement of an old programmable controller and room thermostat. I have some electrical knowledge as an electrician but not specific to heating and controls. So the basics; I have an oil boiler located in...

Hi All, I'm replacing my old analogue thermostat (Sunvic TLX 2259), which currently has 4 wires, a brown, black, light blue and green yellow. Im replacing it with a Salus RT300 digital programmable room thermostat, which has 3 connections; Live, Switch Live and Earth. The controller is...
