4. Main Page Setting

The area to which the information refers is shown at the centre of the display. It is possible to display the information on the Zone and on the domestic hot water part. Simply press the main switch [button-confirm] to cyclically go from Zone to DHW (Domestic hot water). The lower part of the display shows the parameter that can be changed (it varies according to the appliance configuration), it is possible to change the value by turning the main switch and pressing it to confirm the parameter change. The values that can be found according to the configuration, are:

• Set room: Defines the room zone temperature.
• Set flow: Defines the system's flow temperature to the zone.
• Flow offset: Changes the operation curve of the external probe.
• DHW (Domestic hot water) set: This defines the DHW temperature.

5. Summer Mode Functions

With the Zone Remote Panel in Summer mode [?], only the production of DHW is enabled. The DHW setpoint can be set from the dedicated page. If you want to regulate the request for domestic hot water in distinct time bands (Comfort and Economy), it can be set in the Sanitary Setpoint Menu, if the device to which the Zone Remote Panel is connected includes this logic. The time slots used are the same as those used for setting the area's heating / cooling request.

6. Winter Mode Functions

With the Zone Remote Panel in Winter mode [?/?], the production of DHW and room central heating are enabled. Two main functioning modes can be selected for room central heating: automatic or temporary manual.

• Automatic [☀️/?]: The room temperature is regulated on two levels Comfort (sun) and Economy (moon) during the day via a program set by the user.
• Temporary manual [?]: The room temperature is modified momentarily with respect to automatic functioning until the successive passage between Comfort and Economy mode of the automatic program set.

6.1 Automatic Functioning

The Zone Remote Panel allows automatic functioning, in which a program manages the room temperature during the hours of the day. The desired room temperature can be adjusted onto two independent levels: Comfort [☀️] and Economy [?] in the Zone Setpoint menu, whose distribution throughout the day or the week is managed by hourly programming. Press the button until the icon switches-on on the display. The Zone Remote Panel is factory set with a standard program shown below. If this should not satisfy requirements, it is possible to modify it as described in the chapter relative to programming.

Figure 5 displays icons representing operating modes: Stand-by/Antifreeze [❄️], Summer [?], Summer with Cooling [❄️/?], Winter [?/?].

The system is designed to function on Comfort and Economy temperature levels depending on the hour program set. Therefore also during operation on Economy level, if the room temperature measured is below that set, the appliance may function.

6.2 Temporary Manual Functioning

If the room temperature is changed in automatic operation [☀️/?], Temporary manual operation is activated. In this mode, the room temperature will be regulated to the value set until the next switch-on or switch-off phase of the automatic program set. The forced automatic function can be interrupted by simply changing the operation mode.

7. Summer Mode with Cooling Functions

With the Zone Remote Panel in Summer mode with Cooling [❄️/?], the production of DHW, room central cooling and room dehumidifier are enabled. Two main functioning modes can be selected: automatic or temporary manual. These operating modes are similar to those found in the WINTER mode.

The room dehumidification function is activated automatically according to the humidity setpoint set on the Zone Remote Panel (see Zone Setpoint Menu) and the relevant room humidity value measured by the device. The room dehumidification function is a manual function, i.e. it does not depend on the set time program.

8. Operation with External Probe

When the external probe is enabled [?️] in the appliance, the symbol is shown on the Zone Remote Panel display. From this moment, the system's flow temperature for room central heating is calculated depending on the external temperature measured. It is possible to change the operation curve by using the main switch [button-confirm] and changing the external probe offset (Ref. 1 Fig. 4).

9. Time and Program Menu
