Fix CMD_bypass_auto command HEX #11

Closed sodre90 closed 2 years ago

sodre90 commented 2 years ago

It did not work for me. As I checked in https://github.com/michaelarnauts/comfoconnect/blame/master/PROTOCOL-RMI.md#L197 the correct HEX is 85 15 02 01.

You mean bypass? When bypass is activated the air can "skip" the heat exchanger. When it is spring or beggining of the summer days, it can cool your house at night, you can flow in the colder air into your house from outside. If you didn't do bypass then the air flow would go through the heat exchanger so it would be heated by the exhausted air. This specific mode set it into auto mode, so the device will decide if it should be activated or not based on outdoor and indoor temperature. It is a percentage number because it can be partially opened, like 20% bypassed, etc.
