Variable Label Functional Description/Program Options
IN_TOD Used to disable/enable W7600 internal
time-of-day schedules.
When using internal schedules, control will
force occupied mode to match its schedule.
It will not force unoccupied; that is, the
internal unoccupied times can be overridden
from a digital input or from network generated
commands.
DLC_DT The amount of bump to increase the discharge
air temperature setpoint (in DF) to shed load.
This bump will modify the setpoint in the load
saving direction (up for cooling) when a DLC
shed request is received over the CNAP
network. The digital input number 165,
RESTORE_SHED, must be configured
as a remote point to enable this function.
SUPPLY_DUCT_ Cross sectional area, in square feet, of
AREA Supply Air Duct, used to calculate and
control System Air Flow.
Available range of 0 to 10,000 square feet.
Applicable to PM7600B, Version 2.0 or later.
RETURN_DUCT_ Cross sectional area, in square feet, of
AREA Return Air Duct, used to calculate and
control System Air Flow.
Available range of 0 to 10,000 square feet.
Applicable to PM7600B, Version 2.0 or later.
PREHEAT_TYPE Selects type of output to be used to control a
Preheat Coil in the outside air duct.
0 = Staged.
1 = Staged and floating.
2 = Staged and modulating.
Applicable to PM7600B, Version 2.0 or later.
PREHEAT_ Speed, in seconds, of Floating Valve Motor
MOTOR_SPD Actuator for Preheat Coil, from closed to
open. Range is 0 to 255 seconds.
Applicable to PM7600B, Version 2.0 or later.
