⚡ Reliable Emerson 380 Relay Volt Coil for Efficient Electrical Control Review

I replaced my thermostat with a smart thermostat - and this required the use of a 'common' connection to ensure uninterrupted power to the thermostat . Unfortunately, my water heater only had a 24VAC output to turn on/burn, and the thermostat didn't get power after it was connected. The solution was to add a separate 30V thermostat AC transformer that was used to power the low water boiler cut out sensor and switch this relay, completely isolating the boiler thermostat/power control connection…

This little relay is cheap but good quality. I used this along with a 24v wire transformer to power my millivolt kettle. Since my current system didn't have a C wire, just Rh/W wires to turn on the heater, I couldn't just plug my Nest in. After some research it seemed to me that the safest way to add a 24V power supply would be to use a transformer and a relay. Some manuals claim that connecting two transformer wires to the Nest's C and Rc terminals will work (which it will), but you run the…

I bought this as an activation relay for my whole home humidifier project. I have well water, filters and a water softener, it still leaves a ton of white residue and kills almost any type of evaporative based humidifier in 6 months. So I bought a humidifier and hooked it up to a reverse osmosis system. It worked great, except that the water pressure after the reverse osmosis system was not sufficient for the high level of atomization in this humidifier. So I hooked up a 24v auxiliary pump and…
