## Customer Reviews

### ⭐⭐⭐⭐⭐ Did the job, fast delivery, good value.
*by A***. on March 22, 2014*

Relay worked perfectly for Nest Thermostat controlling a gas fireplace. I also had to install a 24VAC transformer. Very simple configuration:1) The N/O switch contact side of the relay is connected across the gas fireplace switch leads.2) Three wire, 18-gauge thermostat cable (red, white, and blue connected to RH, W, and C respectively on the Nest thermostat) was fished through the wall. The Nest was located a few feet from the fireplace about eye-level on the wall. Fishing the wire through the wall was the hardest part of this install.3) Under the fireplace the wire is connected to the secondary 24VAC side of the transformer using the red RH power wire and the blue C common wire.4) The relay coil is connected to the white (W) control wire from of the nest thermostat, with the other side connected to the blue C common wire. In my install, the transformer and relay were tucked underneath the gas fireplace a couple of inches apart.5) Finally, the primary side of the transformer is fitted with a 120VAC cord (only needed to be about 8-inches long in my case) and plugged into 120VAC.6) On my Nest Thermostat, I had to lie to the thermostat and configure it for "electrical heat" rather than "gas furnace" ... I think. I did this and it works. Read it someplace.This is the 4th Nest Thermostat I have in my home but the only one on a gas fireplace, the other three are controlling two other furnaces, one with two zones, and no relay is required for those applications.Shipping was very fast on this product and I have absolutely no complaints. Would buy again... in fact, I'm about to use another of these relays to control my whole-home humidifier... as soon as I can figure out hot to get the additional wire run to the nest. That's another project.

### ⭐⭐⭐⭐⭐ Great for homemade emergency lights
*by V***  on July 26, 2024*

I used your relay for my homemade emergency lighting system and it works perfectly with my LED light and auto charging battery system.

### ⭐⭐⭐⭐⭐ Perfect replacement
*by M***E on February 25, 2025*

Easy replacement for the fan relay on my furnace that was getting stuck on.
