I have just taken the readings
Boiler on and Thermostat calling for heat:
Red - 240v
Yellow - 240v
Blue - 222v
Boiler on with no heat called:
Red - 0
Yellow - 240v
Blue - 222v
Boiler off timed and not calling heat
Red - 0
Yellow - 12v
Blue - 12v
Any ideas?
thanks
Thanks for looking.
I have double checked and this is what I found:
When the boiler programmer is on (Thermostat closed):
T 2 - Live
T 3 - Live
T 4 - Nothing
T 1 - Nothing
When the boiler programmer is on (Thermostat open):
T 2 - Live
T 3 - Live
T 4 - Live
T 1 - Live
Hi all
I hope someone can help?
I'm trying to wire in a Drayton Digistat +3 22083, however the wiring instructions has lost me!
This is my Honeywell
The blue & yellow/brown are live and when it calls for heat the red then becomes live. Is this correctly wired?
The Digistat...
