## Description

Product Description:Compatible with a 2-wire and 3-wire thermostat, this all-in-one relay includes a built-in 24V transformer, replacement for any brand relay.

Easy to Install, merely mounted it on the side of the existing junction box and attached the wires from the new thermostat.Specifications:Transformer Ratings: 24 VAC/ 1.2VA/ Class 2Ambient Operating Temperature: -4℉ to 140℉ (-20℃ to 60℃)Ambient Storage: -40℉ to 175℉ (-40℃ to 80℃)Humidity Limits: 0 to 95% non-condensingTerminal Wire Size: 12 AWG

Review: Works perfectly and exactly as advertised. Key will be longevity. One design feature to be careful of with this is the instant on. If you end up cycling on and off and then back on there is potential to cause damage to your heating circuits. That is NOT a design flaw in this relay, but, a key feature consideration for your usage. That is how it is designed and it is perfect for my application. Most relays have a delay, some as long as 5 minutes.
Review: This is great ! I easily converted the built-in, imprecise, non-gratuated thermostat in my garage 5000W heater with blower to an Ecobee smart and connected thermostat. From Stone age to AI age in 15 minutes. I just ran a 3-conductor thermostat wire to the Ecobee. Wire the 3 wires to corresponding colors. Find a place for this box inside the control compartment of the heater. The res Wire is the switched one. So One phase on the black, one on the blue, red to the thermostat signal. Et voila. Worked like a charm. For really cheap. Identical relays are over 100$ in Canada. This price is great !!!

*by L***A on 9 October 2025*

I was on a brink of returning it, as it turned out a bit larger than I anticipated and couldn't fit in the wire box. Then I cut the drywall and the joist was ~1mm too close to fit it either. So I started my return and started exploring other options. But it turned out that pretty much any other option would be even thicker than this item. So I ended up shaving off 1mm of the joist and fitting it quite securely. It was some mental adjustment (and a triggered breaker) for the red wire not going to the red wire =) There's no audible hum or anything, although there's an audible click when relay switches (which is reasonable). Like others said, adding an extra inch or two to the wires wouldn't hurt at all, but most importantly it sits quite well (where others would not fit), Google Nest learning thermostat works flawlessly, and its cover panel fully covers the cutout. This is a great option for retrofitting an existing baseboard thermostat with a smart one. If you are adding a new wiring box though, I'd consider going with another product that has a proper locking nut.
