Thank you. As a homeowner, I was trying to figure out what actually triggered the Y2 wire on my thermostat. Your explanation was exactly what I needed. Great job!
Hi Mike, your videos are very informative. You are doing a fantastic job. Keep up the good work. No one does it like you do. Mike can you do a video on wiring a Goodman heat pump and a air handler model # GSZV904810-AMVE48DP1400 with a Goodman thermostat?
I recently had a Trane 2-Stage heat pump and Trane 2-Stage furnace installed. They are run thru a Honeywell HZ322 TrueZONE® to two Sensi Smart Thermostats (upper and lower zone). Both thermostats are wired with only RC, O/B, Y, G and W/E. My installer says both pieces of equipment "change stages automatically" and there is no need for the other connections. It was over 100F here and even though I could see stage changes on my HZ322, I could not hear any changes on the heat pump, nor did the unit demand more electricity. I don't believe my system is wired to work correctly. Suggestions?
@@boomguy44 There should be wires connected to the DATS terminals on the zoning board which lead to a temp sensor on the supply air duct. If there is, check the board menu to make sure DATS is active/on.
@@boomguy44 There is a COOL 2 indicator light on the zone board. Does it come on steady at all when the stat is several degrees above set point or does it blink?
Wiring at the control board will be the same. There's a link to another HP wiring video I made in the description that goes into detail on wiring up auxiliary heat and defrost cycles. It uses heat strips as an example but it will be the same wiring for the furnace.
Those are thermostat terminals. The schematic makes it seem like the blocks to the left and right are separate components, but they are all thermostat terminals from a single thermostat.
