Hi all,
we have underfloor heating (water) in our house with a thermostat in each room. As it's an absolute pain to go round programming all of them, I've ordered a smart thermostat to try it out - if it works well I'll replace all of them. I was careful to order a thermostat for underfloor 'water' and not electric although as far as I can tell the difference is in the load the thermostat can drive, 5A water vs 16A electric.
Our current thermostats (generic Chinese branded 'Wunda', model w91.713) have the connections shown on the first photo. Basically power (N,L) + signal L1 closing the circuit to N1.
The new 'smart' thermostat has a different symbol (looks like a motor or valve) with 'open' & 'close' terminals. I suspect that all it does is to close a circuit (N) to either Open or Close and drive a load when under / over the temp threshold. My theory is that if I treat 'Close' as L1 I should be ok? Could anyone confirm if that's the case?
thank you!
