Help with changing wiring of existing tado installation
I've been a tado user for many years and have been very happy with it.
My initial setup was as follows:
Glow worm Flexicom 30sx boiler
Horstmann H37XL controller
3 x wired mechanical room thermostats, split over 2 heating zones (1 in 1 zone, 2 in another)
I now have:
3 x Tado wired thermostats
5 x radiator thermostats
I think like a lot of people, given the current energy crisis, I was reevaluating my heating setup and I've just become aware that my boiler has modulation capabilities. I've been using it and tado in a simple switched live on/off system this whole time. Doing some research it seems tado have engineered compatibility with the glow worm eBus system, meaning I could wire it in such a way as to use this and the modulation capabilities.
Firstly, is this actually possible? If so, I'm hoping to get some advice on how to wire this up
Attached is the wiring on the extension kit. Back when I first did this, I was on and off with support so I'm going from memory. Since it is only a 2 channel kit, I had to wire both heating channels into one. I used a terminal block as it was difficult doing this otherwise. I wired HW as normal. However for CH, support told me to put a jumper between the CH and L (hence the wire going from the terminal block to L)
Is it possible to change this wiring to eBus? I expect the boiler would also need to be changed but I'd likely get a plumber to do that. What changes would I need to make to the extension kit?
Any advice/guidance appreciated
