    My house has central, forced air (20+yo Payne PG9MAA furnace). I’m looking to upgrade my home thermostat to an Ecobee smart t-stat. I currently have a Honeywell unit that works okay, but not great. The switch to the Ecobee is not my biggest concern though: I’m worried that the current wiring...

    So, we finally got around to running new wire from the thermostat to the furnace. We're installing an Ecobee4, which requires a common wire, but we decided on running new 5-wire cable, just in case. Anyways, there's no labels on my furnace and we have no idea how to connect the new wiring. I...

    Hello All, I'm trying to prepare to install my Aprilaire 700M. I'm trying to wire it the same way as the attached picture in color from the Amazon review to work with my Ecobee 4. However, my setup has a zone controller where I have two thermostats connected to the zone controller that can...

    Hey everyone, just installed a Honeywell 360A humidifier last night but have not powered it on yet. I need to get a 3/4" drill bit to get the pressure switch installed.

    If anyone can look at this diagram and let me know how I can connect my "C" (Blue) unused wire to get my ecobee working is appreciated. I tried connecting the "BLUE" to the "C" (while red and white) is already there connected from the A/C and that burned my fuse (3 amp), ended up replacing it...

    I have a g6RC080-16 (no manual anywhere online). I use an ecobee3 thermostat and installed it with 5 wire to my hvac. No big deal. Then I installed a new whole house humidifier since the guy said the solenoid was bad. Installed everything up in a 2-wire install and still no water coming out...

    Hello, I just bought an ecobee3 thermostat for my condo that I am renting. It previously had a Venstar T2800 Thermostat. I have a FHP Bosch EC024- Unit, and I believe it’s a geothermal since there is water connections going in and out and that’s seems to be what I found after doing some...

    I have recently had two HVAC techs install a completely new HVAC system and a new Ecobee Si. One of the guys wired the outside HP and one wired the indoor AH. I know that they had several of the wires wrong because I have checked them ex: the B terminal at the HP was attached to a blue wire...
