Honeywell WiFi thermostat power flickers on and off

I just installed a WiFi thermostat and I am not having constant power. The thermostat will power up, but when I go to adjust the the time and date to set it up it loses power, then a little while later power comes back. Also if I play and jiggle the thermostat will power on and off.

I am trying to figure out if it is a "C" wire problem or if I may have a defective thermostat.

Thank you for help!

I would recheck the wire connections to the thermostat and verify that the mounting screws haven’t damaged the stat wire before trying to exchange the stat.

Does this problem only occur when batteries are not installed in the thermostat?

Thermostat for Heat Pump with Auxiliary Radiator Heat

C

cdrat on May 20, 2018

I have a Bryant 215BNA024-A Heat Pump with Carrier FV4CNF003 L00ABAA Air Handler in a rental apartment that I own. I thought I was getting an Air conditioner but they installed a heat pump by mistake. The heating system for apartment is one zone of a hydronic system. The radiators work fine and the AC system works OK, although I don't think the variable speed is working. The contractor that installed the system said that with the correct thermostat we could use the hydronic system as the backup and take advantage of the heat pump down to about 35° outside (the place is in Washington, DC). Through conversations with Honeywell I purchased The TH6220U2000 Thermostat with the Honeywell C7089U 1006 Outdoor sensor. My contractor has tried very hard to get everything working together but is at his wits end. I looked up the Carrier unit and they recommended a TP-PRH01-B which is a thermostat that uses the variable speed to control humidity (very important in swampy DC) but I do not know if it will also control the radiators as auxiliary heat. [b]Will this thermostat work? Is there a better choice?[/b] Wifi and programmability are not high priorities. Thanks in advance.Read More
