Sorry Guys if this has been covered before but i just wanted some advice. I have and old analogue BG (RS1) i believe its a Drayton and want to replace it with a touch screen programmable thermostat. My understanding is I can set the original programmer set to "on" and I can then use the new thermostat as the main programmer. THe wiring has got me slightly confused as on the old thermostat there is
Red
Blue
yellow
and earth
on the new thermostat there is
L
N
A2
A1
i was told i'd have to loop it ?
not sure how to wire it up. Hope you can help. I can't load the pictures so sorry
i Have a Worcster 9 year old 28cdi combo boiler and a BG UT1 programmer.
I'm sorry again if i have crossed posted but there plumber merchants couldn't help.
Kind regards
David
