Figure 10. Discharge Air Control Heating (DACH) Stages − Default Values Shown
Digital Outputs − P181 and P182
Each output is a fused, dry contact and is rated for 24VAC,
two amp maximum.
Refer to the appropriate unit in tables 6 through 9 to
determine the digital output resulting at different thermostat
inputs. The appropriate digital output LED will be energized
at the same time. The output can also be read with a
voltmeter at P181 and P182. Configuration DIP switches
should be set as shown in tables 3 through 5 for each
type of unit. When an air handling unit is installed, the " G"
output is energized during the occupied time period. See
system parameter A4.01.
All output tables show the G blower output during the
unoccupied time period. During the occupied time period
blower operation will be continuous. If A4.01 system
parameter is changed to option 0, the blower will operate
as shown in tables regardless of time period.
Output tables do not show blower on/off delays.
