Electric / Gas Jumper (Fan Option)
If your emergency or auxiliary system will energize the blower, then jumper W904, on the thermostat base, must be cut (see figure at left). If your emergency or auxiliary heat system requires that the thermostat energize the fan circuit, do not cut jumper W904.
O/B Terminal Switch Selection
The O/B switch on this thermostat is factory set to the “O” position.
This will accommodate the majority of heat pump applications, which require the changeover relay to be energized in COOL. If the thermostat you are replacing or the heat pump being installed with this thermostat requires a “B” terminal, to energize the changeover relay in HEAT, the O/B switch must be moved to the “B” position.
