I have three Two wire Heat only Thermostats connected to a 6 zone Argo controller with 13.7 volts output The other three thermostats control both heat and cooling
Can I connect a "C" wire 24volt transformer to the Nest to make it operate correctly?
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
