Thermostat with display
Description
Thermostat with display for the control of the room temperature in temperature control
systems.
This device can be used both if a temperature control central unit is present or not
present; when appropriately configured it can be used as:
- MyHOME temperature control system probe;
- Hotel room thermostat;
- Residential system thermostat.
It has 4 keys that can be used to select the desired temperature and the various operating
modes; when used with fan-coils it can manage the fan speed.
The thermostat can manage different operating modes: both automatic and manual, in
addition to the Eco, Comfort, Antifreeze/Thermal protection, and OFF.
It can also be used in mixed heating/cooling systems, if the two functions are available
at the same time on the same system.
A contact is also available on the back of the device, to change the operating mode of the
thermostat (e.g. window contact, summer/winter switching, etc.).
