I have recently bought a Drayton wiser single channel. Although the wiring seems pretty straight forward with the enclosed wiring diagram. Has anyone wired this thermostat to opentherm is the wiring the same, doesn't seem to show anything different in the instructions.

What boiler are you trying to wire to? What do you mean is it the same, the same as what?
Hi Chris .Thanks for your reply. Sorry for the confusion when I said wiring to thermostat I should have said heat hub.I think I am sorted now. The boiler is a Baxi 600. I had another look at the wiring instructions supplied and it does show how to wire to the heathub (connection to the small module at the bottom left of the hub). Thanks anyway

Hi Roy
I was hoping you could help me with a similar issue. I have wired my baxi 636 to a Drayton opentherm, however I have noticed I am unable to change the water temperature or the central heating temperature. The water temperature is scalding hot and was wondering if you were able to change it whilst wired in opentherm.

You would be better starting your own post, it is against site rules to Hi-Jack posts and you wont get the proper advice, if you have the single channel you control the HW temp and temp of the radiators at the boiler the drayton wiser single channel is controlled by the air temp in the room it is situated , it can not control HW temp

Be sure to obtain the latest firmware update for the wiser.

Also the Baxi opentherm on the 600 isn't always compatible with products other than Baxi own brands.

The Honeywell t6r doesn't work via opentherm on baxi
