I currently have a Honeywell VisionPro IAQ system that is

Hello.I currently have a Honeywell VisionPro IAQ system that is installed in my house (conventional with gas heat) - the system has 2 thermostats (one upstairs, other down).The thermostats used are the TH9421C1004 7 day programmable.I want to replace the thermostats with Honeywell TH8320ZW (these are Z-Wave compatible for use in my home automation system).Here are my problems / concerns:1. The existing thermostat wiring is simply listed as 1, 2, 3 (which are 1=red, 2=white, 3, blue). The new thermostat terminal block has no 1,2,3 but instead an array of letter codes (C, K, R, RC, Y, W, etc). How do I wire this 3 wire into the new terminal block?2. Obviously it appears this IAQ system does much more than just control temp - the system setup on the existing TH9421C1004 thermostat has several options in system setup that the new thermostat doesn't have -- is this a problem? Am I losing functionality?Kind Regards,Barry

I bought a new nest thermostat which requires a c wire.

I bought a new nest thermostat which requires a c wire. Property management said the c wiring exists but it just needs to be connected properly. I have a blue wire (which I assume is the c wire but the terminals do not seem easily identifiable, says e5 where blue wire is connected in the unit) connected via twist connector to a white wire which relays down to where the condensation pan is. A return white wire then comes back up to the unit where it is connected to the small white wires which go through the wall to the thermostat. I am trying to figure out where to connect the smaller blue wire that goes to the thermostat. I thought it would be an easy connecting of blue wire to blue wire but I am having trouble figuring out why the bigger blue wire connected to the unit terminals is then connected to a white wire.

morning! replaced 16 year old programmable thermostat this weekend We have 2 zone gas/forced air heat and central air with an air exchanger and humidifier. This one is working fine, but now the second zone runs constantly and will not shut off at set point. Current thermostat there has R,Y,W with the fourth wire tapped off.

I have a GeneralAire Dehumidifier in my crawlspace and the

I have a GeneralAire Dehumidifier in my crawlspace and the compressor is running when it shouldn't be. When I bought the unit the fan and compressor turned on/off at the same time unless it was in defrost mode. Now, when the fan shuts off after the set humidity level is reached the compressor continues to run. Besides the compressor issue, the unit is functioning properly and dehumidifying the air like it did when it was first installed. I'm looking for some input on what the problem may be. Here is a link to the product page with some reference info as well. http://www.generalfilters.com/products/de-humidifiers/de-humidifier-1300/DH70-Dehumidifier_PT916.html

We have carrier heating and cooling units with built in

We have carrier heating and cooling units with built in humidistat. My sister keeps turning the humidistat controller all the way to the -20 deg F. Setting/0 % humidity. The controller and manual state you should set the controller to the outdoor temperature and adjust up or down from there. It is summer here. Temps from 70-90 deg. I understand that it is personal preference and condensation on windows, etc...It seems like the "temperature guide" is there for a reason and should be used as the starting point. Am I correct?
