Review on 🌡️ Advanced Emerson Thermostat: White Rodgers 90 340 - Ultimate Efficiency and Comfort by Andre Belitz

This Weil McLain Relay Direct Replacement 510-350-223 is less than half the price. My old one started humming loudly and this replacement is giving me some peace of mind. I bought the same relay in 2018 to use dehumidification mode on my Bryant air conditioner with an Ecobee thermostat that does not support the correct wiring configuration. Since then it has worked without any problems. Both relays (plus the old one from my boiler) make a pretty loud clicking noise when powered. It seems to be a design feature, but I hear it almost everywhere on the 1st floor (boiler in the basement). Not a problem for me, but for others.
