Review on 🔌 Supco 90370 Multipurpose Contacts by Luca Washington

Relay worked well for Nest Thermostat to control gas fireplaces. I also had to install a 24V AC transformer. Very simple configuration: 1) The normally open side of the relay is connected to the gas fireplace switch wires. 2) 18-gauge three-wire thermostat wire (red, white, and blue connected to RH, W, and C). or on the Nest thermostat) have been pinched by the wall. The nest was a few feet from the chimney, at about eye level on the wall. Fishing the wire through the wall was the hardest part of this setup. 3) Under the chimney, the wire connects to the secondary of the 24V AC transformer with the red right power wire and the blue common wire C. 4) The relay coil connects to the white (W) control wire from the Nest Thermostat, and the other side connects to the blue common wire C. In my setup, the transformer and relay were hidden under the gas fireplace a few inches apart. 5) Finally, the primary side of the transformer will be fitted with a 120V AC cord (in my case the length should be around 8 inches). and connected to 120 V AC. 6) With my Nest thermostat, I had to trick the thermostat and set it to "electric heating" instead of "gas oven". I think. I did it and it works. Read somewhere. This is the fourth Nest thermostat I have in the home but the only one on a gas fireplace, the other three control two other stoves, one with two zones and no relay is required for these applications. quickly onto this product and I have absolutely no complaints. Would buy again. In fact, I will be using another one of these relays to control my humidifier at home. once I figure out how to run an extra wire to the outlet. That's a different project.
