Thanks for the detailed information. One thing still confuses me: all the documentation says that IN1 just provides an override to stop operation. (Either when you short it, if SW2-1 is in its default OFF position, or when you open it, if SW2-1 is ON). I can use the Sensors Settings menu to set up any of Control Options A, B or C, via the wireless remote, the thermistor on CN20, or the main controller. There's no specific option for using IN1, which makes sense if it's only an override. So... does the configured thermostat (wireless, thermistor or main) have to be configured to always want heat (e.g. set to 30⁰C or something), and then IN1 is just used to override that to off? Or is there some setting which makes it only look at IN1 and nothing else?
