3.12 - SPECIAL FUNCTIONS
3.12.a -
Air sampling
In heating or cooling mode and with ambient temperature higher or lower than the desired value, the fan
is periodically powered for 1 minute at minimum speed. This way, the system is able to adequately keep
temperature in the room under control and to reactivate faster in case of need.
This function is ONLY active if the unit is installed in high position.
3.12.b -
Commands lock
To lock the keys on board the machine, keep keys "
The activation of the function is verified by the visualization of (BL) on the display every time any key is
pressed.
This function can only be activated/deactivated from board the machine.
3.12.c -
Water not suitable
The effective operation of the appliance in cooling or heating mode is always conditioned by temperature
of water circulating inside the system. If water temperature does not reach a value suitable for the set
mode, so if water is too hot in cooling mode or too cold in heating mode, the fan motor remains off and
the indicator of the current mode (A5) blinks.
- The function is active in cooling mode if the unit is not thermostatic and if water temperature in the
battery is higher than 20°C from more than 5 minutes.
The unit immediately resumes normal operation of one of the two conditions is not met anymore.
- The function activates in heating mode if the unit is not thermostatic and if water temperature in the
battery drops under 30°C (the fan stops immediately).
In heating mode, the unit restarts normal operation only if temperature is higher than 30°C for at least 30
seconds
3.12.d -
Water probe inhibition
If a particular system requires it, it is possible to inhibit the control of the unit on unsuitable water temper-
ature.
- Disconnect the unit from the power supply.
- Disconnect the battery probe from the connector X4
- Switch on the unit and wait that the alarm "E3" appears on the display.
- Press keys "
is disabled and the display shows the desired temperature.
To reactivate the control of water temperature (from disconnected machine), it is necessary to reconnect
the probe.

If the installation of the unit requires it, it is possible to rotate temperature on the display 180° by pressing
"
" (T1) and "
