Hi
I have looked through the forum to try and find an answer to my question, but I couldn't find what I needed, hence this post.
I would like to replace my old mechanical Drayton room thermostat with a new digital Heatmiser DS1-L, but I would like confirmation on the wiring...
Drayton Wires are as follows as per diagram on inside of cover:
3 - Yellow = “Cooling Load”
2 - Yellow = “Heating Load”
1 - Red = “Accel”
4 - Neutral - Blue
Heatmiser Wiring Diagram as follow:
L - Live
N - Neutral
A1, A2 – Heating Connection
I think I am ok with the following (No earth required on this stat I assume)
Red (Live) = L
Blue (Neutral) = N
But I am unsure what should be happening with my two yellow wires and the supply to A1 & A2
When I went to Heatmiser's website and checked the wiring diagram it says something extra:-
"For 230v switching, you need to link from L to A1 and then connect your switch wire to A2", which I assume this means I put a new wire from L to A1.
BUT WHERE DO MY EXISTING TWO YELLOW “COOLING LOAD” & “HEATING LOAD” WIRES GO?
Many thanks in advance.
