Hi EtchenGusev,

Thanks for reaching out. Could you tell us more about the feature that you want to configure? If your Nest Thermostat is already configured for a heat pump, it won't activate your W1 wire when you call for heating.

Thanks,

I have already found out thats impossible to use this thermostat in add on mode so i will install a relay that will work just fine ! Thx Edward !
