CONTROL SYSTEM

Remote thermostat programming

Remote control (wired o wireless) programming

Functions available for the user

The configuration parameters of the remote thermo-

stat must be set on the device itself.

A  long  press  (longer  than  3  seconds)  on  the  OC-

CUPANCY button allows to enter the Programming 

menu from which is possible to modify the parame-

ters listed in the table.

When a parameter is selected the current value blin-

ks. Use the knob to adjust the value of the parame-

ter. Press briefly the OCCUPANCY button to select 

the following parameter.

Press the HEATING button to escape from the Pro-

gramming menu.

The configuration parameters of the remote control must be set on the device itself. Entering the “Operator section” menu it is possible 

to adjust the parameters listed in the table.

Hour, date and language setting

In order to set hour and date enter the “Hour and date” menu and modify the parameters 1, 2 and 3. It is possible to select the desired 

language for the user interface and for each remote control through the “Operator section” menu (parameter 20).

Time tables setting

When the selected operating mode is “Automatic”, the circuits are activated according to the set time tables.

It is possible to set the time table independently for each circuit (heating circuit 1, heating circuit P, domestic hot water circuit, cooling 

circuit 1).
For the cooling circuit 1 it is possible to select, through the parameter 907, whether :

keep the circuit always activated (24 hour per day)

activate the circuit according to time table 5

activate the circuit according to heating circuit 1 time table

For each time table it is possible to specify the program to use in the different days of the week :

daily (a different program for each day of the week)

weekly (same program for all the days of the week)

week end (a program from Monday to Friday and another program from Saturday to Sunday)

For each program it is possible to specify 3 different operating phases per day (6 switch on or switch off events per day).

Holidays setting

It is possible to set a holidays period for the heating circuit 1 and for the heating circuit P.

For each period it is possible to specify the start and the end date and the set point to be adopted during the holidays period.

For details on the settings of parameters 40, 42, 44 and 46 see paragraph “Heating and cooling circuits”.

The room temperature sensor contained inside the remote control can be calibrated adding an offset (parmeter 54) to the value read.
