SmartZone-2L: 2 Zone Controller KIT w/ Temperature Sensor - Replace Honewell, ewc, zonefirst HVAC Zone Control Panels

I was able to use this board to replace an EWC board that was not compatible with ecobee thermostats.The product support was very good, email response in a few hours when I ran into a wire I was unsure about.

Our existing 2 zone controller quick working. I ordered this one hoping it would work and it did.Observations:1) This needs a separate 24V AC power supply to work. I bought a 24V AC power supply from the Home Depot (where they sell sprinkler controllers). So don't forget to order one of these if you don't have one. Remember to get one with the right VA (amps) for your application. The manual has a pretty clear table one the size you need based on the number of external relays/solenoids/etc you need to power.2) I really like that the wiring on this unit doesn't require a tiny screwdriver. The wire connections are accomplished using spring loaded push connections. Nice touch.3) The circuit board is nicely labeled. You can tell this was designed in the USA (I assume). Someone from the marketing side must have insisted the engineers make this device be understandable by non engineers or HVAC folks.4) I also like the clear cover so you can see what's lit up on the circuit board. this thing goes into the attic and if you're going up there to look at tings it's probably because heating / AC has failed which means it's really hot or really cold up there. Being able to see through without needing to remove cover is nice. However, the cover does remove easily if need be.5) Included documentation on configuring / operating was clear and well written. Thanks again marketing guys for proof reading and editing engineer speak.the only negative was my surprise that external power supply was needed. The unit I replaced didn't need this. But then again that unit had failed...maybe because it didn't have external power. :)Overall... nice product!

It is always a challenge to replace something that is not an identical, drop-in unit to the original. With about 20 wires to move over and a different mounting screw location, this would at first glance appear to be a handyman challenge contest. However, the wiring terminals are labelled well and the connections are push in wire keepers. If in doubt, label every wire with its old letter code and which subgroup it came from (and proper wire color code should your wire color not match the diagrams). In a few locations where I had two wires to the same terminal, I found it best to twist the wires together, leaving one at least 1/4" longer than the other so that the single wire would fit in the keeper. Be sure to give each wire a little tug to make sure it is captured by the keepers. In my installation, the old failed controller used power from the furnace, so the recommendation for a dedicated 24V transformer delayed my project until I could procure one. In the end, all worked as advertised with plenty of prompt patient help along the way from their support team. They answered all my questions and made for a high-confidence installation project that worked perfectly from the moment I finished. I like the LED display for operating feedback too.

I began research last week to replace my circa 1987/88 Mastertrol HVAC Control Board. I found EcoJay on line and then saw the great reviews. I was up early before work one day at 6:30AM and emailed the company a few questions. Imagine my shock when Jeff emailed me back within 5 minutes and said would it be OK for a call. At 6:45AM, I was shocked but impressed.Jeff could not have been more accommodating, friendly and full of technical information. After we Hung up I immediately ordered and it arrived yesterday and was installed and fully functional within 1 hour.Directions are super easy and clear and the board works fantastic even with my 3 wire T-Stats, although I think I will run new 5 wire as the Common or "C" wire seems important for the board to operate correctly.Great and easy product and even better people supporting it. I wholly recommend.PS: A local HVAC Company quoted me the Honeywell system which they said would need new thermostats and dampers. (SmartZone works great with all my existing equipment) The Honeywell quote was $2,250, this unit and the extra T-Stat wire cost me about $150. Saved me a small fortune and works GREAT!

This controller replaced a 20 year old Durozone controller.I have to modify the damper motors to use them with this controller, but It wors great.I have some question and customer support helped right away.

This thing is awesome. I took 2 dampers, 2L kit, and 2 ecobees to get proper temperature control in my house. If I could review the dampers I would but I bought those on the ecojay website.This was very easy to implement, I called the owner and asked for help with my thermostat, he suggested that I plug it into the red and fan anytime there is heat called.Good support and a great product.

This zone controller seems undersized and not your typical industrial-sized footprint. However, after installing it and running it for one month, I feel that it's doing it's job. Only time will tell if it will keep running after 20 years. But for now it's doing it's job. Installation was like any other zone controller. The status display is a big plus.

Bought this to replace a zone board that stopped working for one of two thermostats. I took a photo previous model to reference it for wiring. Being that this one wasn't exact layout but similar, rather. It made installation fairly easy. Saved a good chunk of change as I had A/C repairman quote me as much as $300 to do the very same.
