the Economizer feature. When the unit vent is on and
occupied, the thermostat will enable the economizer
relay to keep the outside air damper at the maximum
percentage opening. Only maximum percentage
opening is available; the thermostat will not modulate
the damper. When the unit vent is unoccupied, the
thermostat will close the damper.
