STATUS
CONTINUED
EXH2 OUT OFF ON/OFF Output of AUX1 O terminal, if programmed for EXH2. Displays
ON when damper position reaches programmed percentage
setpoint
ON = 24 Vac Output, OFF = No Output; displays only if AUX1 O =
EXH2
ERV OFF ON/OFF Output of AUX1 O terminal, if programmed for ERV. ON = 24 Vac
Output, OFF = No Output; displays only if AUX1 O = ERV
MECH COOL ON
or
HEAT STAGES ON
0 0, 1, or 2 Displays number of mechanical cooling stages that are active.
Displays the stage of heat pump heating that is active.
FAN SPEED n/a LOW or HIGH Displays speed of fan if JADE is programmed for 2-speed fan.
W (HEAT IN) n/a ON/OFF Displays status of heat if JADE is programmed for 2-speed fan.
SETPOINTS MAT SET 53ºF 38 to 70 ºF;
increment by 1
The economizer will modulate the OA damper to maintain the
mixed air temperature at the setpoint.
LOW T LOCK 32ºF -45 to 80 ºF;
increment by 1
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 controller.
DRYBLB SET 63ºF 48 to 80 ºF;
increment by 1
Dry bulb setpoint will only appear if using dry bulb change over.
Setpoint determines where the economizer will assume outdoor
air temperature is good for free cooling; e.g.; at 63 ºF setpoint
unit will economizer at 62 ºF and below and not economize at
64 ºF and above. There is a a 2 ºF deadband.
ENTH CURVE ES3 ES1, ES2, ES3,
ES4, or ES5
ES curve will only appear if using enthalpy changeover.
Enthalpy boundary “curves” for economizing using single
enthalpy.
See page 11 for description of enthalpy curves.
DCV SET 1100ppm 500 to 2000
ppm
increment by
100
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.
MIN POS 2.8 V 2 to 10 Vdc 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.
VENTMAX 2.8 V 2 to 10 Vdc Displays only if a CO2 sensor is connected.
Used for Vbz (ventilation max cfm) setpoint. VENTMAX is the
same setting as MIN POS would be if you did not have the CO2
sensor.
100 to 9990 cfm
increment by 10
If OA, MA RA and CO2 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 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.
VENTMIN 2.25 V 2 to 10 Vdc Displays only if CO2 sensor is connected.
Used for Va (ventilation min cfm) setpoint. This is the ventilation
requirement for less than maximum occupancy of the space.
100 to 9990 cfm
increment by 10
If OA, MA RA and CO2 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
VENTMIN H (high speed fan) settings are required. Default for
VENTMIN L is 2.5V and VENTMIN H is 2.25V.
