Hi, recently moved home and boiler needed replacing. Had a remeha Avanta 18 fitted and have now found out that need to replace controls.
For ease would like to fit a wireless roomstat as existing has an odd quirk of killing power to the boiler totally even if there is demand for HW. Am going to replace the programmer, pump and valves. these seem easy enough to spec but thermostat instructions talk about "volt free" and also 24v with a two wire controller.
Assume this means the on off is volt free but then goes on to talk about using a modulating opentherm controller??
So what wireless room stat would you recommend to use in the system that would wire straight into the allocated terminals on the board. Clearly wold like the most efficient route as on LPG
Thanks for your help
