DCV MAXIMUM DAMPER POSITION AT HIGH SPEED. Only displays
if unit is set for 2 speed or 3 speed with 1 heat and 2 cool. IF using 2
speed with 1 heat and 1 cool then set for COOLING ventilation. If using
3 speed with 1 heat and 2 cool then set for HIGH SPEED COOLING
ventilation.
DCV MINIMUM DAMPER POSITION AT LOW SPEED. Only displays if
unit is set for 2 speed or 3 speed with 1 heat and 2 cool. IF using 2
speed with 1 heat and 1 cool then set for HEATING ventilation. If using 3
speed with 1 heat and 2 cool then set for LOW SPEED COOLING.
DCV MINIMUM DAMPER POSITION AT MEDIUM SPEED. Only
displays if unit is set for 3 speed with 1 heat and 2 cool. Set for
HEATING ventilation.
DCV MINIMUM DAMPER POSITION AT HIGH SPEED. Only displays
if unit is set for 2 speed or 3 speed with 1 heat and 2 cool. IF using 2

ventilation.
ENERGY RECOVERY VENTILATOR UNIT OUTDOOR AIR
TEMPERATURE SETPOINT
Only displayed when AUX1 O = ERV
Exhaust fan set point for single speed units. Based on OA Damper
position to activate power exhaust.
EXHAUST FAN 1 SETPOINT AT LOW SPEED on 2 speed or 3 speed
with 1 heat and 2 cool. Based on economizer OA damper position to
activate power exhaust.
EXHAUST POINT 1 SETPOINT AT MEDIUM SPEED. Only displays if
unit is set for 3 speed with 1 heat and 2 cool. Based on economizer OA
damper position to activate power exhaust.
EXHAUST FAN 1 SETPOINT AT HIGH SPEED on 2 speed or 3 speed
with 1 heat and 2 cool. Based on economizer OA damper position to
activate power exhaust.
EXHAUST FAN 2 SETPOINT AT LOW SPEED on 2 speed or 3 speed
with 1 heat and 2 cool. Based on economizer OA damper position to
activate power exhaust.
EXHAUST FAN 2 SETPOINT AT MEDIUM SPEED. Only displays if
unit is set for 3 speed with 1 heat and 2 cool. Based on economizer OA
damper position to activate power exhaust.
EXHAUST FAN 2 SETPOINT AT HIGH SPEED on 2 speed or 3 speed
with 1 heat and 2 cool. Based on economizer OA damper position to
activate power exhaust.
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
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
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energize heat pump on heat.
Sets the economizer controller operation based on 1 speed, 2 speed,
2 speed heat/cool (2SP H/C), or 3 speed supply fan.
NOTE: Multi-speed fan options also need Heat (W1) programmed in
AUX 2 In h .
UNIT DESIGN AIRFLOW (CFM)
Enter only if using DCVAL ENA = AUTO
The value is found on the nameplate label for the specific unit.
Select OUTPUT for AUX1 O relay
• NONE = not configured (output is not used)
• ERV = Energy Recovery Ventilator
• EXH2 = second damper position relay closure 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.
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.
