INSTALL 01/01/10 Display ord er = MM /DD/YY
Setting order = DD, MM, then YY.
UNITS DEG _F _For_C Sets economi zer controller in degrees Fahrenheit or Celsius.
EQUIPMENT CONV Con ventional or HP CON V = conv e nt ional;
HP O/B = Enable Heat Pump mode. Use A UX2 I for Heat Pump i nput from
therm ostat or contro ller.

HP (O)
HP (B)
In CONV mode:
SD = Enables conf ig urati o n of shut d o w n (default ) ;
W = Informs controller that system is in heating mode.
NO T E : If usin g 2---speed fan mode, you mu s t prog r a m CONV mod e
forW.Shutdownisnotavailablein2---speedfanmode.
SeeMenuNote4.
In HP O/B mode:
HP(O) = energize heat pump on Cool (default);
HP(B) = energi ze heat pump on Heat.
FAN SPEED 1speed 1 speed/
2 speed
Sets economizer controller for operation of 1 speed or 2 speed supply fan.
The controller does not control the fan but posit i ons the OA and RA
dampers to the heating or cooling mode. See page 32 for modes and
position.
NO TE: 2--- speed fan opti on also needs Heat (W 1) programmed in
AUX 2 In. See Menu Note 4.

NONE = not configured (output is not used)
ERV = Energy Recovery Ventilator

EXH2 = second damper position 24 Vac out for second exh a u st fan
SYS = use output as an alarm signal
OCC INPUT INPUT or ALW AYS OCCUPI ED MODE BY EXTERN A L SIGN AL
When usi ng a se t bac k therm ostat wit h occup a nc y out (2 4 Vac), the 24 Va c
is input “INPUT” to the OCC terminal. If no occupancy output from the
thermostat then change program to “ALW AYS” OR add a jumper from
terminal R to OCC terminal.
SeeMenuNote1.
FACTORY DEFAULT NO NO or YES Resets all set points to factory defaults when set to YES. LCD will briefly
flas h YES and change to NO but all parame ters will change to the fac t o ry
de fault values.
