EXPANDED PARAMETER NAME
[
Display order = MM/DD/YY
Setting order = DD, MM, then YY .
Sets economizer controller in degrees Fahrenheit or Celsius.
CONV = conventional;
HP O/B = Enable Heat Pump mode. Use AUX2 I for Heat Pump input from
thermostat or controller.
See Menu Note 4
In CONV mode:
SD = Enables configuration of shutdown (default);
W = Informs controller that system is in heating mode.
NOTE: If using 2---speed fan mode, you must program CONV mode
for W. Shutdown is not available in 2---speed fan mode.
See Menu Note 4.
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energize heat pump on Heat.
Sets economizer controller for operation of 1 speed or 2 speed supply fan.
The controller does not control the fan but positions the OA and RA
dampers to the heating or cooling mode. See page 32 for modes and
position.
NOTE: 2---speed fan option also needs Heat (W1) programmed in
AUX 2 In. See Menu Note 4.
UNIT DESIGN AIRFLOW (CFM)
Enter ONLY if using DCVCAL ENA = AUTO
The value is found the nameplate label for the specific RTU.
Select OUTPUT for AUX1 O relay
NONE = not configured (output is not used)
ERV = Energy Recovery Ventilator
EXH2 = second damper position 24 Vac out for second exhaust fan
SYS = use output as an alarm signal
OCCUPIED MODE BY EXTERNAL SIGNAL
When using a setback thermostat with occupancy out (24 Vac), the 24 Vac
is input "INPUT" to the OCC terminal. If no occupancy output from the
thermostat then change program to "ALWAYS" OR add a jumper from
terminal R to OCC terminal.
See Menu Note 1.
Resets all set points to factory defaults when set to YES. LCD will briefly
flash YES and change to NO but all parameters will change to the factory
default values.
NOTE: RECHECK AUX2 IN and FANTYPE for required 2---speed
values.
SUPPLY AIR TEMPERATURE LOW LIMIT
Temperature to activate Freeze Protection (close damper and alarm if
temperature falls below setup value)
FREEZE PROTECTION DAMPER POSITION
Damper position when freeze protection is active
CLO = closed
MIN = MIN POS or VENTMAX
CO ppm level to match CO sensor start level.
2 2
CO ppm span to match CO sensor. e.g.; 500---1500 sensor output would
2 2
be 500 CO zero and 1000 CO
2
COOLING STAGE 3 DELAY
Delay after stage 2 for cool has been active. Turns on second stage of
mechanical cooling when economizer is first stage call and mechanical
cooling is second stage call. Allows three stages of cooling, 1
economizer and 2 mechanical.
OFF = no Stage 3 cooling.
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., Y1---O, Y2---O,
EXH1, etc. will shut off.
NOTE: Function NOT AVAILABLE with 2---speed mode
Used for alarm for when the DA air temperature is too low. Set lower range
of alarm, below this temperature the alarm will show on the display.
Used for alarm for when the DA air temperature is too high. Set high range
of alarm, above this temperature the alarm will show on the display
Turns on the DCV automatic control of the dampers. Resets ventilation
based on the RA, OA and MA sensor conditions. Requires all sensors (RA,
OA, MA and CO ).

NOTE: This operation is not operable with a 2---speed fan unit.
