New heating control not connecting

[Daljit]

Hi

I have a Glowworm Energy(7) 30C and tried fitting a Drayton prog thermostat but it doesn’t seem to be doing anything!

The boiler’s manual shows it’s pretty straightforward to connect a battery operated wired thermostat - just connect two wires to the eBus terminals. I’ve done this but the boiler just doesn’t seem to be doing anything different - it still operates to the basic settings I entered for the flow temperature.

The instructions look so easy but for some reason boiler not listening to the control?!

Any ideas?

Ebus is specifically for Vaillant/Glow worm products, you have wired it incorrectly. Which Drayton have you bought? Also you may, depending on the boiler cover, need to carry out critical safety checks afterwards.

As @CBW you cant wire a Drayton into the Ebus on that boiler

Hi

Thanks for the responses. That makes sense. I’ve fitted a few of these over the years and each time I’ve had to remove a little wire/bridge on the boiler. So, I take it I should be using the terminals marked 24V?

Are you a gas engineer or landlord?

It depends on what the Drayton is designed to be connected to. Most are volt free, but not all.

Hi

It’s a Drayton Digistat, which can be connected with a battery or mains.

You can use either 24v or mains switching on that model, so either will be fine, just not eBus.

Landlord it is then!
