The following table allows you to customize the options on your Comfort-Set thermostat. Begin by pressing simultaneously the 

two buttons in step 1.

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.

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 ther-

mostat 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.
