I have a pretty complex HVAC Infinity system with 3 units
I have a pretty complex HVAC Infinity system with 3 units and of course thermostats. I specify that in winter the humidity rate is ordered by only one of the thermostat which receives the outside temperature information, so the other thermostats don't have any possibility of order about the humidity rate inside the house. The problem is that one of the thermostats has a command "button", on the middle right of the side of the box, which is broken and does not respond when you press it. To replace this thermostat, do you think that I should ask to our usual HVAC Company, or may I do that myself (in our previous house, I have replaced myself a simple Honeywell 4 wires). Also what would be the best thermostat choice ? … read more
