NOTE: If FAN button is pressed again or if no
button is pressed for 60 sec, thermostat will exit
configuration mode and return to normal operation.
To re-enter configuration mode, the FAN button
must be pressed and held for 10 sec again.

(2.) Use up and down buttons until thermostat display

reads "6-."

(3.) Press MODE button once to display current selec-

tion of OF, 15, 20, 25, 30, 35, 40, 45, 50, or 55.
Value should be OF for feature disabled.

(4.) Use up and down buttons to change from OF to 1 of

the available temperature choices. Value will de-
pend on ambient temperature at which heat pump
can no longer handle heating load.

(5.) Press FAN button to exit configuration mode.

b. Programmable Model

(1.) Enter thermostat configuration mode by pressing

and holding FAN button for approximately 10 sec.
The room temperature disappears and display
should read "--." Thermostat is now in configura-
tion mode.
NOTE: If no button is pressed for 10 sec, thermo-
stat will exit configuration mode and resume normal
operation. To re-enter configuration mode, FAN
button must be pressed and held for 10 sec again.

(2.) Press COPY PREVIOUS DAY button to display

current selection of OF, 15, 20, 25, 30, 35, 40, 45,
50, or 55. Value should be OF for feature disabled.

(3.) Use the up and down buttons to change from OF to

1 of the available temperature choices. Value will
depend on ambient temperature at which heat pump
can no longer handle heating load.

(4.) Wait 10 sec to exit configuration mode.

12. Jumper terminals W2 and E on unit terminal strip. This

allows electric heat to be activated when EMERGENCY
HEAT option is selected at thermostat.

13. With an electronic thermostat such as this one, it should not

be necessary to change the factory default heat anticipation
setting. Consult thermostat Installation Instructions if heat
anticipation must be adjusted.

NOTE:

Refer to Installation Instructions packaged with thermo-

stat for additional information.

D.

Make Low-Voltage Connections at Unit

Attach thermostat wires to low-voltage terminal block on left side
of control box in locations indicated on label adjacent to terminal
block or appropriate thermostat wiring diagram in these instruc-
tions.

NOTE:

Any unused conductors of thermostat cable not required

should be left unattached.

CAUTION:

Recheck wiring color code schedule to be

certain proper terminals are connected before applying
power. Improper wiring or installation may damage
thermostat.

(Non-Programmable Electronic Thermostat)

NOTE:

Terminals O/W2, Y1, and L are not used on thermostat. An

outdoor temperature sensor must be connected to thermostat terminals
S1 and S2. X terminal on control voltage terminal strip must be
connected to C terminal on thermostat for proper thermostat opera-
tion. Terminals W2 and E must be jumpered on unit terminal block.
