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.

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.
SUPPLY AIR TEMPERATURE LOW LIMIT
Temperature to achieve Freeze Protection (close damper and
alarm if temperature falls below setup value).
