Description

Instead of saying it could be powered by either batteries or 24V they should say batteries and/or 24V. Still it could well be that this lithium battery keeps the programming intact also and the alkaline batteries power the communications, I don't know. These radio-using devices require wired-power -- 24VAC -- to talk to sensors so I decided to reuse the existing two wires to supply that, with the signaling done wirelessly. We sell into the residential, commercial and industrial market segments for new construction, replacement, repair, remodel, parts and service.

With 45,000+ SKUs, Famous Supply specializes in HVAC, plumbing, industrial, building products, and training. My new thermostat booted and I was able to pair it with an in-house and an outside sensors with ease. The THM5421R1021 module controls up to 4 stages of heat and 2-stages of cool in a heat pump system and up to 3-stages of heat and 2-stages of cool in a conventional system. They are also powering the totally wireless communication betweem my stat and the furnace via the equipment interface module which is in turn hard wired to the furnace.Applications include Gas, oil, electric, heat pump, forced warm air, hot water, steam or gravity systems. Discover indoor and outdoor LED lighting options from undercabinet to ceiling and vanity, you can trust Bright33 for convenience, quality and value. Their wide range of offerings include thermostats, zoning solutions, and air purifiers, helping to make living and working environments comfortable and efficient. This statement makes me think that both the 24VAC and the batteries can be connected at the same time because of the backup reference, but I'm not sure.

I'm not impressed by honeywell either as I have written to them several times and I never get any responce. Styles from transitional to modern and traditional, you can count on Craft33 cabinets to compliment your clients’ lifestyle and budget.The THM5421R1021 interface module streamlines the performance of the system helping clients reduce energy costs. Thinking, I may have a defective unit, I exchanged it -- but now the replacement is doing the same thing. From mini split systems to room air conditioners and dehumidifiers and registers, you can count on Breeze33 for convenience, quality and value.

Honeywell's Equipment Interface Module (EIM) THM5421R1021 IAQ was supposed to help there -- hooked up to the TACO 406 ZVC in the boiler room instead of the thermostat, and talking to the thermostat via Honeywell's proprietary RedLink-protocol.

Honeywell is the backbone of the HVAC industry, helping to improve the lives of consumers by providing innovative, cutting-edge solutions. However when I checked the thermostat terminals for 24V with my own meter I was still not seeing this voltage.

I suspect most installers and homeowners will be mostly concerned with how to install the equipment properly and less with the engineering details about how the electronics actually work. It features three sets of universal IAQ contacts to control humidification, dehumidification and ventilation. The Equipment Interface Module controls up to 4-stages of heat and 2-stages of cool in a heat pump system and up to 3-stages of heat and 2-stages of cool in a conventional system.
