I have an Envision system connected to an Intellizone zone control, two zones, with Honeywell thermostats. The system was installed in the fall of 2011 and I moved into the house Jan 2012. Several weeks ago the system faulted with low pressure / flow, and my first notification of the fault was the huge electric bill. Powering the system off and on again reset it, and it's been running almost a week with no problems. Is there a thermostat that I can install or some other system that will alert me remotely of a fault in the system? The installer tried installing a different Honeywell thermostat but he removed it after discovering it would not alert to faults either. I asked about using a Waterfurnace thermostat and he can get one for me, but I was reading the installation manual for the Intellizone and it says So does that mean I won't be alerted to a fault with the Waterfurnace thermostat, or just won't be alerted to the specific fault? Searching this forums and others says that Honeywell 8000 series thermostats will alert if they get 24v on L, but does the Intellizone pass a signal from the Envision to the thermostats?
I received an answer from Waterfurnace So I should be able to use a Honeywell VisionPro 8000 thermostat and get alerts, right? Right now I have two FocusPro 5000 thermostats.
I might try wiring the "L" to a thermostat, the one you see the most, bypassing the board. One does not want to mix and match transformers, so you might want a relay. All you want is to "see" is a fault before you get your electric bill. Mark
Yes - 8000 series display a highly visible red light when stat "L" is connected to Intellizone "LO" I got a call about one yesterday.
