Micro-switches SW1 allow the configuration
of the following parameters:
- Pin 1: Lock keyboard. In OFF the keyboard
is not locked. In ON the keyboard is locked
and the locked keyboard symbol (
) is
displayed. The buttons that remain active
are:
,
and
(outdoor tem-
perature reading).
- Pin 2: AUTO PROG mode activated. De-
fines whether the automatic air condition-
ing mode with time schedule program-
ming (time schedule profiles) can be acti-
vated. OFF indicates the AUTO PROG
mode is deactivated, and ON indicates the
AUTO PROG mode can be selec-
ted.
- Pin 3: O/B signal: Set to OFF, heat is gen-
erated when the O/B (24 VAC) signal is
active, and cool when inactive. Set to ON,
cool is generated when the O/B (24 VAC)
signal is active, and heat when inacti-
ve.
- Pin 4: 2 minutes/4 minutes. Defines the
time between the end of one phase and
when it can be active again. OFF indicates
2 minutes, and ON, 4 minutes.
- Pin 5: Multi-stage. Defines single-stage
(one stage can be activated only) or multi-
stage (more than one can be activated).
OFF indicates single-stage and ON, multi-
stage.
- Pin 6: Single-speed fan. Defines whether
the fan can operate at one or three
speeds. OFF indicates 3 speeds and ON,
1 speed. In single-speed, the wind icons
are not displayed.
Alarms
The alarm codes are displayed at the bot-
tom left of the screen, overlapping hour and
minutes.
The alarm codes are as follows:
- 0-90, machine error codes (If there is com-
munication).
- 91, temperature origin selected is invalid.
- 92, indoor temperature sensor not cali-
brated.
- 93, communication alarm.
- 94, alarm with terminal "AL" connected.
- 95-99, digital probe not detected.
When an alarm is generated, the wrench
symbol is displayed. If the error is machine
or communication, this symbol flashes. Ter-
minal "AL" is an input signal of phase "R"
that activates, on the thermostat display,
failure code 94. Use if there is no communi-
cation with the thermostat and the control
is equipped with terminal "AL".
Filters. If the dirty filters symbol is displayed
flashing, the filters need to be changed.
Dead battery. The dead battery symbol indi-
tes the batteries are dead, and these should
be changed. System configuration is not lost
when changing the batteries. Only day and
time are lost.
Installation instructions
It is recommended that the installation be
carried out by a qualified personal.
Location
To assure adequate operation, this thermo-
stat should be installed on an indoor wall,
in a frequently occupied area of the build-
ing. Furthermore, it should be at at least 50
cms. from any outside wall, and at approxi-
mately 1.5 m. above floor level, in an area
with freely circulating air at average tem-
perature. The following locations should be
avoided:
- Behind doors or in corners where freely
circulating air is unavailable.
- Where direct sunlight or radiant heat gen-
erated by other appliances may alter the
control operation.
- On an outside wall.
- Next to or in line with air conditioning dis-

- Where operation can be affected by steam
or water pipes, or hot air chimneys in ad-
jacent areas or any other unheated/
uncooled area behind the thermostat.
- Where operation can be affected by the
supply air of any adjacent unit.
- Near sources of electrical interference,
such as arching relay contacts.
Basic elements
This thermostat comprises three parts:
- Hinged front cover.
- Front panel. This element contains the
operating and control keys, as well as the
printed circuit. Fastened to the base by
means of a plastic tab.
- The base. This box allows fastening the
thermostat to the wall, and contains the
electrical connecting strips.
Thermostat installation
To fasten the thermostat to the wall, open
the front panel and uncover the base of the
thermostat. Proceed as shown in the follow-
ing illustration:
1- Press the plastic tab at the base of the
thermostat, as indicated by arrow A.
