I have a 3 zone baseboard hot water heating system. I purchased 3 nests and also 3 nest power connectors. We do not have a c wire which is why I bought the power connectors. The nests are installed and the power connectors are installed at the taco zone controller. I am having weird heating issues where if you turn the thermostat on to heat zone 3, I only get heat in zone 1 and zone 2 (those thermostats are off) and NOT in zone 3 which is the thermostat I turned on to heat. If I turn on zone 2 to heat, I only get heat in zone 1 and not in zone 2 or zone 3. This all worked fine before the nests.
Hey there, I haven't heard from you in a while so I'll be locking this thread. If you have any new issues, updates or just a discussion topic, feel free to start a new thread in the community. Thanks, Oana.
