The Celcia 20 doesn't support smart power, so the medium power request must have been detected erroneously. As a result of this misunderstanding the gateway starts sending different bit levels. It's not surprising that the thermostat then doesn't understand the messages anymore and reports a communication error.casio wrote:Not sure but just before things go err there is an error 3 reported on which the gateway reduces the power to medium followed by a second error 3.
I will have to find a way to either prevent or recover from this situation. The methods that come to mind are:
- Only accept smart power requests if the thermostat has indicated support for it.
- Return to low power mode if the thermostat repeats the same message some number of times.
I think the answer is yes, but the question is not entirely clear to me. After a while the gateway figures out that your thermostat is a Celcia 20 (you can check with PR=R). It will then use the Celcia specific method for manipulating the setpoint. The Celcia doesn't allow any distinction to be made between TT and TC.casio wrote:Finally, I noticed that with the Celcia 20 if you use TT=xx the thermostat programmed timer is not picking up. Is this related to the fact that the TT command is actually a TR command under the hood after the gateway detected that the thermostat is a Remeha Celcia?
