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.

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.

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.

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.

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.
