Changing thermostat temp set point via eDLT

Shocked to discover that the C-bus thermostats I bought CAN'T be controlled by an eDLT. This makes them pretty useless for me. Surely there must be a way to achieve this? Otherwise what was the point in them?

There's gotta be a way to hack it together, or else by using logic? If anyone has any ideas please let me know.

 

Just curious. Given to can change the set point with the thermostat, why do you want to change it via an eDLT?

 

The same reason people use the remote control when they change TV channel - because it's handier.

I have an eDLT at either side of the bed and one in the living room so me or my partner can control the lights/fan/alarm and hopefully temperature.

I've figured out a way to hack the heating controls using scenes and dummy lamps, but I'd really prefer to remove my existing cloud based smart thermostat and do it all within C-bus.

There's gotta be a way to adjust the set temperature on the C-Bus thermostat using logic somehow. Otherwise it's just a dumb thermostat, and there'd be no point hooking it up to C-bus.

 

The only devices that supported the hvac protocol were the touch screens, wiser I & II, and the Pascal Automation Controller. Schneider dumped all of these (including the thermostats) and replaced them with the SHAC which doesn't support the hvac protocol. A major backward step in my opinion as the Cbus function in the SHAC are very limited and poorly implemented. But that's progress for you.

The Pascal Automation Controller is the simplest solution (albeit a bit of a learning curve) but it will give you a lot more options to control the system.

Alternatively if you are handy with any programming language, you can talk to CGate directly and do anything you want. If you have a serial interface and a spare PC it's a no cost option.

 

Thanks for the detailed reply.

Yeah I have my C-bus setup permanently connected to my home server over RS232.

The PAC seems to be the cheaper option rather than buying software licenses etc, so I'll probably go for that if you're 100% sure I'll be able to make it do what's needed.

 

Thanks, Nick.

All I need it to do is switch a boiler on/off via a single relay. There's no other fancy stuff. I assume I just assign a spare relay? Hopefully I can just use one on the same module that I share with lighting?
