## 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. Compatible with 24V thermostats with 3-wire connections (R, W, C) or 2-wire connections (R, W). Immediate relay activation provides improved temperature control and comfort. 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: A+ Exceptional Relay for the Price - Time will tell on longevity - 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: Works perfectly so far! - I was able to use this to control a 240V load of 3 baseboard heaters (wired in parallel) from an Ecobee3 smart thermostat. I simply wired it up according to the provided diagram and everything worked perfectly. There's even a green LED light on the unit that indicates when it's activated. Note that if you plan to use your thermostat to control both baseboard heating (via this device) *and* an AC unit for cooling, this is considered a "dual transformer" configuration. In that case, the C wire must come from the cooling unit, not the heating unit, so you should use the 2-wire configuration (R and W only) for this device and leave the C (brown) wire disconnected.

### ⭐⭐⭐⭐⭐ Worked well to allow my low volt Tstat to control my 230v electric heaters
*by M***R on December 29, 2024*

I had installed another known brand similar device which failed after 4 years. With most active devices, it failed to full heat position, not ideal for energy consumption. This device has a convenient indication light, nice for troubleshooting. I used a separate 24vac source to power the Tstat, more than the internal power available from this device, since I needed a constant source to allow Redlink communications for this Tstat and have remote connectivity. Overall, quiet, works well. Installed in wall enclosure behind a hinged door.
