Hiya Folks, I'm in the process of installing a unit heater in the garage. I've got a Totaline 474-0100 TStat that I'm trying to get wired up. This is a simple
2 wire system. I'm getting no display on the TStat. I've got one of the wires going to R and the other to W1 and have confirmed I'm getting 24V. Now I would suspect a bad display at this point but I took it in the house and wired it into our furnace the exact same way and get a display just fine. Any ideas? Thanks much, jlc- posted
