Display order = MM/DD/YY
Setting order = DD, MM, then YY.
UNITS DEG F F or C Sets economizer controller in degrees Fahrenheit or Celsius.
EQUIPMENT CONV

HP
CONV = conventional;
HP O/B = Enable Heat Pump mode. Use AUX2 I for Heat Pump input
from thermostat or controller
h
.
AUX2 IN W
SD/W or
HP(O)/HP(B)
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
h
.
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energize heat pump on heat.
FAN SPEED 2 speed
1 speed
2 speed
2SP H/C
3 speed
Sets the economizer controller operation based on 1 speed, 2 speed,
2 speed heat/cool (2SP H/C), or 3 speed supply fan.

SYS
Select OUTPUT for AUX1 O relay
• NONE = not configured (output is not used)
• ERV = Energy Recovery Ventilator
g
• EXH2 = second damper position relay closure for second exhaust fan
• SYS = use output as an alarm signal
OCC INPUT
INPUT or
ALWAYS
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.
FACTORY DEFAULT NO NO or YES
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.
