Hi-- I replaced my old thermostat (a Maple Chase) with a Venstar T1800, with Insteon attachment. It worked fine throughout the summer, but once we got into the heating season, it became a little less fine. The heat kicks on, and a couple of minutes after that, the thermostat loses power. The wiring from the furnace to the thermostat has five wires, four of which were used by the MC. I connected the unused wire to the C lead on both the thermostat and the furnace so that the thermostat would power up. It's a single-zone gas furnace with an A/C unit. My guess, from reading threads here and elsewhere, is that the 24v R connection doesn't get power when the blower kicks on, or something along those lines. I posted the wiring diagram from inside of the furnace cover at [URL="https://files.me.com/flenser/6hjk5l"]https://files.me.com/flenser/6hjk5l[/URL]. I didn't embed the image directly, since it needs to be fairly large to make out the diagram. So, what's the best way to fix this? Should I wire the R wire that runs to the thermostat to a different place than the terminal it's connected to? Thanks for any help!

I have a Honeywell TH3210D wired as follows: E.......Jumper to Aux Aux....White Wire Y........Yellow Wire G........Green Wire O........Orange Wire L.........None R.........Red Wire B.........None C..........Blue Wire I am replacing the Honeywell TH3210D with a White Rodgers 1F85-277 Would the wiring go as follows? E/W1........Jumpered to W2 W2...........White Wire Y1............Yellow Wire G..............Green Wire O..............Orange Wire L...............None R...............Red Wire B...............None C...............Blue Wire Y2.............None On The White Rodgers... The ELEC/GAS switch set to ELEC Configuration Menu set to HP2 Are there any other settings I should be aware of? Thanks.
