Kind of a vague question, i have been troubleshooting my thermostats and i had some questions on why i have two separate zone boards. This boils down to i was told to make sure i have relays on my thermostats and i see two out of the three zones, but the one without a relay has some temp settings.
Can someone help me out and explain the difference between the two zone boards? thanks
