They have finally completed intallation of my zoned HP system. It's been running about a month, but it does not seem to operate as I might expect. Here's the specs:
Am. Stnd. 5 ton HP with dual fuel and two compressors. This is their 19 SEER unit. Variable speed Am Stnd. air handler. Honeywell 4 zone contol system with two zones being utilized. The two stats are Honeywell programable and have the hold button on the front.
We are still finishing up the home so we have not yet moved in. I have reset the stat schedule so that every time period the heat is set on 60. The stat always shows the room temp is 60.
I don't understand why the stat triggers the unit to come on even when the room temp does not change. It's almost like it's on some kind of timer. The stat makes a "click", the unit comes on, runs for a short period maybe 2 or 3 minutes then it purges and shuts off. The same routine begins again a few minutes later, the room temp has never changed.
I don't know why it does this? Shouldn't the stat show a reading of 59 degress before the unit kicks on? I had hoped getting the high efficiency HP would be benifical, but I don't imagine I'm get much efficiency with such short cycling.
Any thoughts before I call them back for a second look?
