Problem with the multiple circuits

Post by Sdke »

Hello

I have an Elco Thision (english manual: https://www.libble.eu/elco-thision-s/on ... al-789399/)

I have 2 circuits:
Circuit 1 is for my floor heating. I have the Smart Modulating Thermostat installed.
Circuit 2 is for my normal radiator with an Smart Thermostat installed + 6 smart valves installed.

When my radiators need to heat up the system, it works. When my floor heating needs to heat up, it works. But when both need to heat up I get an error code on my system (110).

Error 110 means 'STB lockout'. STB seems to be a 'safety temperature limiter'.

The original setup was as follow:
Circuit 1 had my normal Smart Thermostat installed
Circuit 2 had a bridge installed to be always on and I used the Smart Valve Radiator Starter Pack.

There is something with the Smart Modulating Thermostat that makes my boiler go to hot. Sadly, I'm not albe to control the heat of the water through the OpenTherm Modulating part..

Help me?
