Review on Transformer Thermostat Competible Versions Honeywell by Cedrick Ayudara

I used this in a slightly different format than most. My Payne oven has a C-wire, but during each heat cycle there is a fan delay timer where the fan runs and air circulates in the oven. During this time, the voltage on my Ecobee thermostat dropped and turned off the unit, delaying the next heating cycle and causing the thermostat to lose communication with remote temperature sensors, WiFi, etc. I reconnected this device to the oven. , disconnected wire C from the oven board and connected to the wire on this unit. Then connect another cable to the RC connector of the stove. (Final circuit) Whalla 25 volts to Ecobee thermostat through fan delay cycle. Such a simple solution and no extra holes in the walls. It worked perfectly!
