In case of prolonged stop of the machine, it must be deactivated turning the main switch off or unplugging the machine
from the mains.
3.3.4 Well-being key (automatic operating)
When button T2 is pressed, UNICO BOILER MASTER will automatically arrange to obtain optimal comfort in the room that is
conditioned. In relation to the internal temperature of the room, the conditioner will automatically set the operating mode (cooling,
ventilation or, if available, heating), the temperature and the fan speed.
3.3.5 Cooling
When used in this mode, the air conditioner dehumidifies and cools the room.
Activate this mode by pressing button T4 (Run mode selector) until the snowflake symbol D3 is displayed.
In this run mode, the required temperature and fan speed can be set. After three minutes (as a maximum) from activation in this
operating mode the compressor will start and the appliance starts emitting cold air.
Start up of the compressor is indicated by the lighting up of the green LED B (fig. 24) positioned on the console.
3.3.6 Dehumidification only
When used in this mode, the air conditioner eliminates the humidity in the room. This function can be extremely useful between
seasons, particularly on rainy days when the temperature is not uncomfortable but the excess humidity feels unpleasant.
In this mode, both room temperature and fan speed settings are ignored, which correspond to minimum.
As such, no temperature and fan speed indications are displayed.
Activate this mode by pressing button T4 (Run mode selector) until the droplet symbol D4 and automatic ventilation symbol D1
are displayed. In this operating mode it is normal for the air conditioner to function intermittently.
3.3.7 Ventilation only
When used in this mode the air conditioner does not perform any action with regard to temperature and air humidity in the room.
Activate this mode by pressing button T4 (Run mode selector) until the fan symbol D1 is displayed.
At this stage you can select the fan speed (see paragraph 3.3.10).
WARNING: air emission is temporarily suspended while hot water is being produced.
3.3.8 Heating
When used in this mode the air conditioner heats the room. This function is only available on models with a heating pump (HP).
Activate this mode by pressing button T4 (Run mode selector) until the sun symbol D2 is displayed.
In this run mode, the required temperature and fan speed can be set. After three minutes (maximum time) the compressor should
start and the air conditioner starts heating the room. The start of the compressor can be checked through the lighting of the relevant
green LED located on the console.
WARNING: the emission of hot air may be temporarily suspended in order for hot water to be produced only in the case
of a UNICO BOILER WALL with the Turbo1 and/or Turbo2 function enabled (Fig. 43).
3.3.9 Air flow direction control
By pressing button T9 it is possible to activate/deactivate the continuous swing of the mobile air outlet baffle. When the continual
swing is activated, one further press of button T9 will block the baffle so that the desired vertical direction of the air flow is obtained.
IMPORTANT: Movement of the mobile baffle must never be forced manually.
3.3.10 Checking fan speed
Fan speed is checked by button T5. Pressing this button several times will change the speed in this order: Low, Medium, High and
Automatic.
The higher the speed setting, the greater the output of the air conditioner but also the louder its operation. By setting the Automatic
mode, the onboard microprocessor adjusts the automatic speed. The higher the difference between the room temperature detected
and the temperature set, the higher the speed.
As the room temperature nears the setting, fan speed is reduced automatically.
In dehumidification mode, it is not possible to control the speed as the appliance can only operate exclusively at low speed.
If both units are in operation, UNICO and SPLIT ventilation is limited to low speed.
