a) Cooling

Press

MODE

button alternatively until

the cool symbol

appears on the

screen (along with the word COOL)

(Fig. 3).

Once the operating mode is set, select

the temperature setting by pressing

button

or so as to set a higher

or lower temperature. The temperature

seting appears along with a small sym-

bol that represents a thermometer, and

remains on screen for 5 seconds. When

the temperature setting disappears, the

ambient temperature appears once

again.

After a few minutes, the cooling system

will begin to operate and the cooling

symbol on screen will start to flash.

b) Heating

Press the

MODE

button alternatively

until the heating symbol appears on

the screen (along with the word HEAT)

After a few minutes, the heating system

will begin to operate and the heating

symbol on screen will start to flash.

c) Automatic

Press the

MODE

button alternatively

until the heating and cooling sym-

bols appear on the screen (along with

the word AUTO) (Fig. 5).

Select a temperature setting for the cool-

mode as desribed in paragraphs a) and

b). In this operating mode, the COOL

temperature setting should be least 1°C

above the HEAT temperature setting,

which is the minimum differential al-

lowed by the thermostat. Press the

MODE

button repeatedly displays the cooling

or heating set points. After 5 seconds

the ambient temperature is displayed

(Fig. 5).

After a few minutes, the system will

beging to operate, switching automati-

cally between the heating and cooling

modes so as to keep the ambient tem-

perature between the two settings.

When either the heating or cooling

mode are in operation, the correspond-

ing symbol starts to flash.

d) Automatic programming

If this option is not selected, it will not

appear (can be selected by setting mi-

cro-switch No. 2 to ON). Press the

MODE

button alternatively until the heat-

ing

and cooling symbols are dis-

played (along with the words AUTO

PROG). The selected time schedule pro-

file is also displayed (Fig. 6).

For correct operation of this mode, first

you must set the time on the clock and

select the number of the day of the week.

Then select the desired time schedule

profile for the different days of the week.

See the section on Programming Menu.

Select a temperature setting for the cool-

ing mode and another for the heating

mode, in accordance with the program-

ming menu. (Fig. 6)

In this mode you must define the tem-

perature set point for day, night and un-

occupied conditions.

After a few minutes, the system will start,

switching automatically to either the heat

or cool mode and keeping the ambient

temperature between the selected set

points and in compliance with the time

schedule profile selected.

e) Emergency heat

Press the

MODE

button alternatively

until the words EMERG HEAT are dis-

played, along with the heating sym-

bol. After a few minutes, the emergency

heat will begin to operate and the heat-

ing symbol will flash on the screen.

In this operating mode, the compressor

is always inoperative and the auxiliary

and emergency heaters (optional acces-

sories), if installed, are used for heat-

ing.

This operating mode can be used for

heating when there is any problem with

the compressor (Fig. 7).
