Manual Override Switches

For testing and during start-up each Data Aire gForce unit is provided with manual override slide

switches. There are seven slide switches. One for each of the following functions:

Water Valve

Fan Speed

Humidifier

Heat 1

Cool 2

Cool 1

Blower

All automatic control is disabled but the safety switches remain functional. Simply slide the manual

switches to energize the blower, compressors, humidification, reheat and other functions.
The fan speed of the EC (Electronically Commutated) motor can be adjusted from 0 – 10 volts by

adjusting the potentiometer at the left of the

Fan Speed

switch. The fan will turn 10% for each volt

adjustment. One volt equals 10%. At ten volts the motor is at full speed.

Warning:

Do not leave the unit in manual override. Slide the switches to the OFF position when

completing testing and/or start-up. An alarm will be activated if units are left in the ON position.
