Notes
Enthalpy boundary "curves" for economizing
using single enthalpy. See "" on page 19 and
Product Data sheet form 63-2700 for description
of enthalpy curves.
Displays ONLY if a CO2 sensor is connected.
Setpoint for Demand Control 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.
Displays ONLY if a CO2 sensor is NOT
connected. 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
Displays only if a CO2 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 With 2-speed
fan units VENTMAX 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
Displays only if CO2 sensor is connected. Used
for Va (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 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
Only when AUX1 O = ERV
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%
