Review on Technologies RC840T 120 Electromechanical Relay Built by Greg Quinit

Controlled by Next Generation Nest Thermostat (white with color display). The relay controls the wall socket to which the electric oil cooler is connected. We tried different settings and this combination provided perfect heating for a 120m2 apartment. feet within a few weeks. It is also nice that the Nest can use a relay to tell you how long the radiator (convection only, not a fan) needs to heat up the room and then optionally start the heating process earlier to keep the room at the set temperature. at the desired time. The relay circuit worked flawlessly every time. The Nest is fully charged by Aube's built-in 24V transformer via a common cable. I would like to point out that only the heating can be controlled, but I think if you also had cooling (i.e. a plug in a window unit) the same process could be used for that as well (or two relays for that matter and a wire). one for heating and one for cooling). I'm thinking of trying a second unit on a room evaporative cooler. When I do I will update these results.
