Manual Override Switch Board

For testing and during startup each gForce unit is provided with manual override slide switches. There
are seven (7) slide switches. One for each of the following functions:
All automatic control is disabled but the safety switches remain functional. Simply slide the manual
switches to energize the fan, compressor(s), humidification, reheat and other functions (as applicable).
Some DAM may have a special Electronically Commutated (EC) plug fan motor and the fan speed can
be adjusted from 0 to 10 volts DC by adjusting the potentiometer at the left of the Fan Speed switch.
The fan speed will increase 10% of the fan base speed for each one (1) volt adjustment (e.g., one (1)
volt equals 10% speed). At ten (10) volts the motor is at full speed.
NOTICE: The Manual Override Board with switches was previously available
on units before April 2021.
Units built after April 2021 do not include this board.
