EXHAUST STAGE 2 RELAY OUTPUT
Output of AUX1 O terminal Displays ON when damper position reaches
programmed percentage setpoint
ON = 24 Vac Output, OFF = No Output; displays only if AUX1 O = EXH2
ENERGY RECOVERY UNIT RELAY OUTPUT
Output of AUX1 O terminal, ON = 24 Vac Output, OFF = No Output;
displays only if AUX1 O = ERV
Displays stage of mechanical cooling that is active.
Displays the stage of heat pymp heating that is active.
SUPPLY FAN SPEED
Displays speed setting of fan on a 2-speed fan unit.
HEAT DEMAND STATUS
Displays status of heat demand on a 2-speed fan unit.
SUPPLY AIR SETPOINT
Setpoint determines where the economizer will modulate the OA damper
to maintain the mixed air temperature. See Note 2.
COMPRESSOR LOW TEMPERATURE LOCKOUT
Setpoint determines outdoor temperature when the mechanical cooling
cannot be turned on. Commonly referred to as the Compressor lockout. At
or below the setpoint the Y1-O and Y2-O will not be energized on the con-
troller.
OA DRY BULB TEMPERATURE CHANGEOVER SETPOINT
Setpoint determines where the economizer will assume outdoor air tem-
perature is good for free cooling; e.g.: at 63°F (17°C), unit will economize
at 62°F (16.7°C) and below and not economize at 64°F (17.8°C) and
above. There is a 2°F (1.1°C) deadband. See Note 3
ENTHALPY CHANGEOVER CURVE
(Requires enthalpy sensor option)
Enthalpy boundary "curves" for economizing using single enthalpy.
See page 45 for description of enthalpy curves.
DEMAND CONTROLLED VENTILATION SETPOINT
Displays only if CO sensor is connected. Setpoint for Demand Controlled
2
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.
VENTILATION MINIMUM POSITION
Displays ONLY if a CO sensor is NOT connected.
2
With 2-speed fan units MIN POS L (low speed fan) and MIN POS H (high
speed fan) settings are required. Default for MIN POS L is 3.2V and MIN
POS H is 2.8V
DCV MAXIMUM DAMPER POSITION
Displays only if a CO sensor is connected. Used for Vbz (ventilation max
2
cfm) setpoint. VENTMAX is the same setting as MIN POS would be with-
out the CO sensor
2
If OA, MA, RA, and CO sensors are connected and DCV CAL ENABLE is
2
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 CFM.
With 2-speed fan units VENT L (low speed fan) and VENTMAX H (high
speed fan) settings are required. Default for VENTMAX L is 3.2V and
VENTMAX H is 2.8V
DCV MINIMUM DAMPER POSITION
Displays only if CO sensor is connected. Used for Va (ventilation min
2
cfm) setpoint. This is the ventilation requirement for less than maximum
occupancy of the space.
If OA, MA, RA, and CO sensors are connected and DCV CAL ENABLE is
2
set to AUTO mode, the OA dampers are controlled by CFM and displays
from 100 to 9990 CFM.
With 2-speed fan units VENTMIN L (low speed fan) and VENTMIN H
(high speed fan) settings are required. Default for VENTMIN L is 2.5V and
VENTMIN H is 2.25V.
ENERGY RECOVERY VENTILATOR UNIT OUTDOOR AIR TEMPERA-
TURE SETPOINT
Only when AUX1 O = ERV
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%
EXHAUST FAN STAGE 2 SETPOINT
Setpoint for OA damper position when exhaust fan 2 is powered by the
economizer. Only used when AUX1 O is set to EHX2.
With 2-speed fan units Exh2 L (low speed fan) and Exh2 H (high speed
fan) settings are required. Default for Exh2 L is 80% and Exh2 H is 75%
