Thermostat with display
Configuration
The thermostat can be configured:
- Through physical configuration, by connecting the configurators to the appropriate
housings on the back of the device. This quick mode is ideal for basic functions, and
gives the possibility of setting, in addition to the zone address, also a heating load,
a cooling load, up to 2 system pumps, and a quick function for the remote contact.
- Using MyHOME_Suite (*), where a dedicated wizard will guide the user through the
procedure for correctly configuring the device. The MyHOME_Suite software gives the
possibility of customising the device and provides a higher degree of functionality,
such as:
- The possibility of changing some default parameters (select the unit of measure for the
temperature, change the permitted operating temperature, manage the backlighting
level, disable some device pushbuttons, etc.).
- Configure a higher number of loads (up to 9 heating and/or cooling actuators and 9
pumps), and assign slave probes (max. 9).
- Enable advanced functions, like automatic switching between heating and cooling.
- Manage dedicated fan-coil settings (e.g. fan speed change threshold settings, or fan
activation delay, etc.).
- Set a delay or a timeout for the actions generated by the status change of the remote
contact (in addition to allowing a higher number of combinations than through the
physical configuration).
1.1 ADDRESSING
By connecting two congurators with value 0-9 in the ZA and ZB sockets, it is possible
to set the device address. The controlled actuators will have to be congured with the
same address.

1.2 OPERATING MODE
By configuring the positions TYPE, HEAT, COOL, PUMP and IN, it is possible to set the
desired operating modes and the types of loads to manage.

(1) If the device is used as a MyHOME system probe with temperature control central
unit, the subsequent positions HEAT, COOL, and PUMP must not be congured. The
settings for actuators and pumps will be dened directly from the central unit menu.
HEAT= Heating load. Configure the corresponding actuator with N=1.
COOL= Cooling load. For the configurations from 1 to 9 configure the corresponding
actuator with N=2. In case of CEN configurator the actuator will be N=1.
