SETUP
INSTALL 01/01/10 Display order = MM/DD/YY
Setting order = DD, MM, then YY.
UNITS DEG _F _For_C Sets economizer controller in degrees Fahrenheit or Celsius.
EQUIPMENT CONV Conventional or HP CO N V = conve nt ional;
HP O/B = Enable Heat Pump mode. Us e AUX2 I for Heat Pump input from
therm ostat or controlle r.
SeeMenuNote4
AUX2 IN n/a Shutdown (SD)
Heat (W1)
HP (O)
HP (B)
In CONV mode:
SD = Enable s configuration of shutd o w n (de fa ult );
W = Informs controller that system is in heating mode.
NO T E : If usi n g 2--- speed fan mode, you must progr a m CONV mode
forW.Shutdownisnotavailablein2---speedfanmode.
SeeMenuNote4.
In HP O/B mode:
HP(O) = energi ze heat pump on Cool (default);
HP(B) = energize 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 posi t ions the OA and RA
dampers to the heating or cooling mode. See page 31 for modes and
position.
NO TE: 2---speed fan optio n also need s Heat (W1) 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 ou t for second exhaust fan
SYS = use output as an alarm signal
OCC INPUT INPUT or ALWAYS O CCUPIED MODE B Y EXTERNA L SIG N AL
When using a set b a c k thermostat wi t h occupancy out (24 V ac), 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
termi nal 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 para m e t e rs wi ll chang e to the facto ry
de fault values .
NO T E : RECHECK AUX2 IN and FA NTYP E for requ i r ed 2--- speed
values.

COOLING STAGE 3 DELA Y
Delay after stage 2 for cool h as been active. Turn s on second stage of
mechanical cooling when economizer is first stage call and mechanical
cooling is second stage call. Allows th r ee stages of cooling, 1
economizer and 2 mechanical.
