Operation ON/OFF will depend on remocon request.
When Heat Mode is running with Contact Open, user change this setting to contact close, indoor will this signal to
remocon judge and change mode to cool and send back to indoor. And it is same as from cool mode change to
heat mode.
* This switch have higher priority, remocon follow indoor send signal when control activated.
* There is no effect to the operation when the mode running is only Tank Mode.
