Call Bill @ Honeywell

Yes, the VP and the VPIAQ models both have programmable hold. You can set back or up for multiple days, then have it revert to the regular program, say when your flight is due to land. You also can set it to heat/cool your vacation home, coming out a couple hours before your usual arrival time on Friday PM. That way, you won't walk into a stifling beach house or a cold ski house any more. With the VPIAQ, you can have a telephone access module that allows monitoring, emergency call out, and remote system/temperature changes via cell or any other touch-tone phone. Go to www.customer.honeywell.com, scroll down to the right, find the "Literature" box, and type in TH8110,and download the installation & set-up manaual. No password required, and no charge.

    Hi Bill,

    I posed the following question to Carol Fey yesterday and she wasn't sure of the answer. Maybe you could shed a little light on the subject:

    When the VISIONPro 8000 is programmed to hold a certain temp for a number of days, is it in increments of 24 hours from the time of day that it was set? How exactly does it work?

    Thanks in advance, Adam

    Hello Adam......

    If you hold the temp on the Vision Pro 8000 it will stay there indefinitely until the program is resumed. As clear as I can remember, it will hold at the time you set it. If that is one of the options. I am not looking at the manual, but I am sure Bill will help you out is I am incorrect. Generally a temporary override will hold the temp you set it for until the next program change rolls about and then get back on the train and ride out the program. If you hold it,.It will stay where you set it until run program is initiated again...

    Hey, Ed!

    The VisionPro IAQ Package can be configured 2 ways. The TH9421C1004 is capable of up to 4 stages of heat, 2 stages of cooling. It mounts in the occupied space, and works and programs just like the VisionPro Touchscreen. Three wires run from the TH9421C to the THM5421C1002 interface module, which is installed in the equipment room. The wiring is just like any T'stat, R,Rc,W,Y,G. OT terminals are for optional indoor & outdoor temp sensors. You also have terminals for a humidifier, de-humidifier and ventilation. Phone output is provided for the optional Telephone Access Module. They are sold as a kit, YTH9421C1002, for non zoned equipment. They are also offered in 2 & 3 zone Kits for the Networked Forced Air Zoning System. They are available from any Honeywell distributor, but the forced air oriented guys are more likely to have them in stock.
