If the outdoor
dewpoint rises above
this setpoint, the
unit will activate the
Dehumidifi cation
Demand.

Setpoint
OcpClSt
AO: 42
If the control
temperature rises one
degree above this
setpoint, the control
will activate the cool-
ing demand. If the
control temperature
is the Supply Air Sen-
sor, then the cooling
demand is always
active.

Setpoint
OcpHtSt
AO: 43
If the control

one degree below
this setpoint,
the control will
activate the heating
demand. If the
control temperature
is the Supply Air
Sensor, then there is
no heating demand.

Warm Up
Setpoint
WmupSt
AO: 91
In a VAV
application, upon
entering the

Warm-up Demand
will be activated
if the return air

Coil
Temperature
Setpoint
CoilTpSt

dewpoint in the
supply air
approximately 10°F
above this setpoint.

UnClOst
AO: 124
During the
Unoccupied Mode
of Operation, this
Setpoint spreads
the Occupied Cool-
ing Setpoint out by
a user adjustable
amount. If you do
not want Cooling to
operate during the
Unoccupied Mode,
use the default
setting of 30°F for
these setpoints.
