ERV Operation: When in Cooling mode AND the conditions are NOT OK for economizing - the ERV terminal will be energized.
In the Heating mode the ERV terminal will be energized when the OA is below the ERV OAT setpoint in the setpoint menu.

JADE™ ECONOMIZER MODULE
Notes
Indicates shutdown signal from space thermostat or
unitary controller. When controller receives 24 Vac
input on the SD terminal in conventional mode, the
OA damper will open if programmed for OPN and
OA damper will close if programmed for CLO. All
other controls, e.g., fans, etc. will shut off.
Turns on the DCV automatic control of the dampers.
Resets ventilation based on the RA, OA and MA
sensor conditions. See Product Data sheet 63-2700
for details. Requires all 3 RA, OA and MA sensors.
Setpoint determines where the economizer will
modulate the OA damper to maintain the mixed air
temperature.
Setpoint determines outdoor temperature when the
mechanical cooling cannot be turned on. Commonly
referred to as the Compressor lockout.
Setpoint determines where the economizer will
assume outdoor air temperature is good for free
cooling; e.g.; at 63 ºF unit will economizer at 62 ºF
and below and not economize at 64 ºF and above.
There is a a 2 ºF deadband.
Enthalpy boundary "curves" for economizing using
single enthalpy.
See "Enthalpy Settings" on page 15 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.
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).
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.
Only when AUX = ERV
Setpoint for OA damper position when exhaust fan 1
is powered by the economizer.
Setpoint for OA damper position when exhaust fan 2
is powered by the economizer. Only used when AUX
is set to EHX2.
