Setting Functioning Parameters; Setting The Heating Parameters - Riello Condexa Pro3 Series Installation Instructions Manual

9 SETTING FUNCTIONING PARAMETERS

The heating functions can be set for the high temperature, low temperature and DHW circuits based on the system requirements
by setting the functional parameters.
The first three parameters can be accessed on the user level. The next three require a password ("22", see the "INSTALLER PROGRAM-
MING mode" chapter in the "User interface" chapter.
To access the user parameters, press the
− manifold delivery temperature T1
− DHW temperature T3
− low temperature circuit delivery temperature T6.
To change the relative setpoints:
− press the "Set/esc" button: the relative value will appear, the two digits on the right will flash
− press and until obtaining the required value. Press "OK" to save the new value. The displayed value will stop flashing
after 3 sec and will be operative.
A detailed description of all the parameters and the factory preset values can be found in the "Parameter list" chapter.

9.1 Setting the heating parameters

The following heating parameters can be set:
1 Setpoint_T_CH_High
High temperature circuit setpoint (parameter 1)
If the "fixed point" operating mode is set (par. 14=CH_type_high=0), it is the target temperature.
If the "climatic control" operating mode is set (par. 14=1) , it is the maximum target temperature with minimum outdoor temperature
(T_out_min=par. 37, preset to 0°C).
parameter 18 (T_ch_high_foot, preset to 50°C) defines the minimum setpoint at maximum outdoor temperature (T_out_max=par.
38, preset to 18°C).
Preset to 70°C and upper value limited by par. 17 (T_ch_high_limit, preset to 80°C).
