Displays the stage of heat pump heating that is active.
FAN SPEED
N/A
LOW or HIGH
SUPPLY FAN SPEED
Displays speed setting of fan on a 2-speed fan unit.
W (HEAT ON)
N/A
ON/OFF
HEAT DEMAND STATUS
Displays status of heat demand on a 2-speed fan unit.
SETPOINTS
MAT SET
53F
38°F to 65°F
(3°C to 18°C);
increment by 1°F
SUPPLY AIR SETPOINT
Setpoint determines where the economizer will modulate the OA
damper to maintain the mixed air temperature.
LOW T LOCK
32F
–45 to 80 F
(–43°C to 27°C);
increment by 1°F
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical
cooling cannot be turned on. Commonly referred to as the
Compressor lockout.
DRYBLB SET
63F
48°F to 80°F
(9°C to 27°C);
increment by 1°F
OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoint determines where the economizer will assume outdoor air
temperature is good for free cooling; e.g.; at 63°F unit will economize
at 62°F and below and not economize at 64°F and above. There is a
2°F deadband.
ENTH CURVE
ES3
ES1,ES2,ES3,ES4,
or ES5
ENTHALPY CHANGEOVER CURVE
Enthalpy boundary “curves” for economizing using single enthalpy.
DCV SET
1100 ppm
500 to 2000ppm;
increment by 100
DEMAND CONTROLLED VENTILATION
Displays only if CO
2
sensor is connected. Setpoint for Demand
Controlled Ventilation of space. Above the setpoint, the OA dampers
will modulate open to bring in additional OA to maintain a space ppm
level below the setpoint.
MIN POS
2.8 V
2 to 10 Vdc
VENTILATION MINIMUM POSITION
Displays ONLY if a CO
2
sensor is NOT connected.
VENTMAX
With 2-speed fan units
VENTMAX L (low speed
fan) and VENTMAX H
(high speed fan)
settings are required
2.8 V
2 to 10 Vdc
DCV MAXIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Vbz (ventilation
max cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA,OA, and
MA). In AUTO mode dampers controlled by CFM.
100 to 9990 cfm;
increment
by 10
If OA, MA, RA, and CO
2
sensors are connected and DCV CAL
ENABLE is set to AUTO mode, the OA dampers are controlled by
CFM and displays from 100 to 9990 CFM.
2 to 10 Vdc
With 2-speed fan units VENT L (low speed fan) and MIN POS H (high
speed fan) settings are required. Default for VENTMAX L is 3.2V and
VENTMAX H is 2.8V
VENTMIN
With 2-speed
fan units VENTMIN L
(low
speed fan) and
VENTMIN
H (high speed fan) set
2.25 V
2 to 10 Vdc or 100
to 9990 cfm
increment by 10
DCV MINIMUM DAMPER POSITION
Displays only if a CO
2
sensor is connected. Used for Ba (ventilation
min cfm) setpoint. Displays 2 to 10 V if <3 sensors (RA, OA, and MA).
Va is only set if DCV is used. This is the ventilation for less than
maximum occupancy of the space. In AUTO mode dampers
controlled by CFM.
100 to 9990 cfm;
increment
by 10
If OA, MA, RA, and CO
2
sensors are connected and DCV CAL
ENABLE is set to AUTO mode, the OA dampers are controlled by
CFM and displays from 100 to 9990 CFM.
2 to 10 Vdc
With 2-speed fan units VENTMIN L (low speed fan) and MIN POS H
(high speed fan) settings are required. Default for VENTMIN L is 3.2V
and VENTMIN H is 2.8V

EXHAUST FAN STAGE 1 SETPOINT
Setpoint for OA damper position when exhaust fan 1 is powered by
the economizer.
With 2-speed fan units Exh1 L (low speed fan) and Exh1 H (high
speed fan) settings are required. Default for Exh1 L is 65% and Exh1
H is 50%
