I have been fighting with the ZTT000 for almost a week now and finally took it out!
First, it was the wiring...the instructions showed one thing, until finally found a NEW set of instructions which showed something totally different.
I have a simple central A/C system with electric heat. The old thermostat was a Honeywell T8401C with W, Y, G, R, C (5-wire) connectors. Based on the "revised" wiring diagram, the following connections were made:
W: White & black
The thermostat started just fine, registered on the Z-Wave network fine, came up in Homeseer 2.0 (although it took some time before the software picked up the current temp)- I could live with that...BUT here is the kicker...The current temp is 70, Heat set point is 75, Cool set point is 77 AND the A/C starts to push COLD air!
Could somebody shed some light on what is going on here...we are freezing!
