Micro-switch SW1 allow the configuration of the following pa-
rameters:
- Pin 1: Lock keyboard. In OFF the keyboard is not locked. In
ON the keyboard is locked and the locked keyboard icon
(key) is displayed. The keys that remain active are:
,
and
(Consult outdoor temperature).
- Pin 2: AUTO PROG mode activated. Defines whether the
automatic air condition mode with time schedule program-
ming (time schedule profiles) can be activated. OFF indi-
cates the AUTO PROG mode is deactivated, and ON indi-
cates the AUTO PROG mode can be selected.
- Pin 3: O/B signal: Set to OFF, heat is generated 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 inactive.
- 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 acti-
vated). OFF indicates single-stage and ON, multi-stage. In
heat, if stage W exists, in single-stage Y1 and W are acti-
vated.
- Pin 6: Single-speed fan. Defines whether the fan can oper-
ate at one or three speeds. OFF indicates 3 speeds and
ON, 1 speed. In single-speed, the wind icons are not dis-
played.
By default, all micro-switches are set to OFF.

Alarms
The alarm codes are displayed at the bottom left of the screen,
overlapping hour and minutes.
The alarm codes are as follows:
- 0-90, machine error codes.
- 91, temperature origin selected is invalid.
- 92, indoor temperature sensor not calibrated.
- 93, communication alarm.
- 94, Failure with terminal "AL" connected.
- 95-99, Digital probe not detected.
When an alarm is generated, the wrench icon is displayed. If
the error is machine or communication, this icon flashes; if
not it remains static.
Filters. If the dirty filters icon is displayed flashing, the filters
need to be changed.

Temperature control
The purpose of this thermostat is to keep the room at the
temperature established by the set points. When operating in
AUTO or AUTO PROG, the heat and cool set points are used.
However, when operating in HEAT the heat set points are used
only, and when operating in COOL the cool set points are
used only. When the temperature between the real tempera-
ture and the set point is more than 0.2° C, the first stage Y1 is
activated. If after a while (depending upon the temperature
control operating mode TURBO, NORMAL, ECONOMY) the
temperature has not recovered, the second stage Y2 is acti-
