I have a gas forced air furnace with 2 zones, upper level and lower level. The zones are controlled by a Honeywell mini zone controller EMM-3. My problem is that when upper level zone calls for heat, lower level zone lights up and also heats even when the thermostat is in the off position or set lower than room temperature. Any ideas? I tried moving the two zones to 2 and 3 on the board, but that did not help. In the photo one thermostat is off and as you can see both zones are lit up.
