Re: UT-3000 with bypass humidifier

meassick, Sorry for the late response. We have had extremely high tech call volume and have not paid sufficient attention to the forum. Sir, it appears that someone has programmed one or both CTK04's to "humidify" without heat!....This is a function in the "Installer Menu" of eac...

Re: HVAC not responding and the BMPlus 3000 LED's are off

tnormile, Sorry for the late response. We have had extremely high tech call volume and have not paid sufficient attention to the forum. Sorry your BMP failed and it appears the BMP was powered via the same 24vac transformer in the furnace, rather than a dedicated transformer, as specified in the tec...

Re: Swapping EWC-ST-2E for NCM-300

Eddie23, Sorry for the late response...We have had extremely high tech call volume over the last 6 months and have not paid sufficient attention to the forum. You don't have to use the "SAS" supply air sensor but we highly recommend it. If you decide to install and use it, drill the hole i...

Re: What's the definition of percentage in a zone, and what is it used for?

Anibal, The UT3000's PID loop and zone weighting features are a means of insuring that any zone can receive the proper BTU capacity. As Tony pointed out, there's some math involved but it's not complicated. You don't have communicating thermostats, so the UT3000 will always interpret your thermostat...

Re: NCM-300 w/ecobee tstats

By the way...it appears that you are missing a jumper from Rc to Rh on the Ecobee sub-base with the bubble level.

Re: NCM-300 w/ecobee tstats

Sir, That does'nt make any sense unless your NCM300 is being powered from the Furnace transformer, rather than a dedicated transformer. According to your pictures, each thermostat already has a 24v common wire. Please don't do anything until you call and talk to us!...Do you have a voltmeter?...we'l...

Re: UT3000 not configuring single stage heat pump

Sir, Unfortunately, a non-communicating Amana heat pump along with a communicating Amana furnace IS NOT a valid equipment configuration in the "ComfortNet" family of equipment. By wiring the HP in straight cool mode, your contractor was able to get everything to work. A non-communicating A...

Re: Thermostat recommendation for UT-3000

Richarda, Red Link is not the same as Climate Talk. Red Link is Honeywell's "wireless" feature/function, that allows you to connect auxiliary devices such as Outside air sensors, Room sensors, Remote access Gateway, etc. Climate Talk is the "wired" protocol/language that the HVAC...

Re: Thermostat recommendation for UT-3000

Richarda, As a follow-up to your post. Any (non-communicating) Honeywell Thermostat that is "Red Link" capable can be used as Zone 2 & 3. They would be picked up by the HW Gateway just like the CTK04 would. You could create a "portfolio" of thermostats to monitor on your Smar...
