Introduction
It is possible to use the thermostat with display both with heating and cooling systems, locally
(using the available keys) and remotely (using the Hotelsupervision software, MyHOME_Up or
HOMETOUCH - see the Thermostat Use) section.
The LED display shows the current mode of operation (Antifreeze/Thermal Protection or Heating/
Cooling), the room temperature measured, the temperature set point, the fan-coil speed, the
window contact status and the zone status.
If the temperature measured is below the reference set point value, the heating system is activated
and the corresponding symbol appears on the display.
If the temperature measured is above the reference set point value, the cooling system is activated
and the corresponding symbol appears on the display.
The thermostat can be programmed (ask your trusted installer) for automatic switching between
heating and cooling based on set thresholds.
Reference temperatures configured by the installer using MyHOME_Suite and Hotelsupervision
(Eco, Comfort and Protection).
After configuration, they can be activated using MyHOME_Up or Hotelsupervision

Setpoint that in a heating system sets the minimum safety temperature to 7°C (Antifreeze) and in a
cooling system the maximum safety temperature to 35°C (Thermal Protection).
These values may be changed by your installer using MyHOME_Suite and Hotelsupervision.
Upon opening of the local contact (e.g. window contact), the display shows the corresponding
symbol, which will disappear again once the contact is closed. Using MyHOME_Suite and
MyHOME_Up, the installer can set an action or a scenario to be performed upon opening/closing
of the contact.
