Condenser
Position 2
CdPos2 AI: 247 Current Condenser
Position for 2nd unit.
Dewpoint
Setpoint
DptSt AV: 13 If the outdoor
dewpoint rises above
this setpoint, the
unit will activate the
Dehumidifi cation
Demand.
35 80
Occupied/
Mode
Enable
Cooling
Setpoint
OcpClSt AV: 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.
0 99
Occupied/
Mode
Enable
Heating
Setpoint
OcpHtSt AV: 43 If the control
temperature drops
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 AV: 91 In a VAV
application, upon
entering the
occupied mode, the
Warm-up Demand
will be activated
if the return air
temperature falls
one degree below
this setpoint.
50 90
Coil
Temperature
Setpoint
CoilTpSt AV: 107 This is the coil
suction temperature
target during
dehumidifi cation
mode. Produces
dewpoint in the
supply air
approximately 10°F
above this setpoint.
35 70
Indoor
Humidity
Setpoint
InRhSt AV: 120 If the indoor
humidity rises
above this setpoint,
the unit will
activate the
Dehumidifi cation
Demand.
0 100
Unoccupied
Cooling
Offset
UnClOst AV: 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.
