To modify a parameter, press the
button and the current value will be displayed. It can be modified with the
and
buttons. Press the
button to validate.
Modulation.
Possible values: 1 (modulation ON), 0 (modulation OFF).
Units.
It is possible to change temperature units (ºC Celsius, ºF Fahrenheit). Default value: ºC.
Legionella.
1 (Legionella protection ON)
0 (Legionella protection OFF).
AUTO heating regulation
. If a fan outdoor temperature probe is installed it is possible to
activate the auto heating regulation by shifting this parameter value to 1. Only visible when P05 is
activated.
TIMAX.
Maximum water flow temperature in AUTO heating mode. Only shown when P05 is
activated.
TIMIN.
Minimum water flow temperature in AUTO heating mode. Only shown when P05 is
activated.
TEMAX.
Outdoor temperature from which the water flow temperature will be TIMIN. Only
shown when P05 is activated.
TEMIN.
Outdoor temperature below which the water flow temperature will be TIMAX. Only
shown when P05 is activated.
6.7 HEATING MODULATION FEATURE
The advanced control board on the boiler will automatically modulate the heating output to the demand required
to save energy.
This function works by the boiler ‘learning’ and anticipating the time taken to reach the temperature level
demanded by the external thermostatic control. The power output is automatically adjusted therefore reducing
power consumption on warmer days or when another heat source is present.
An external ‘volt free’ control must be fitted across the terminals marked ‘TA’ on the PCB and the ‘bridge’
removed for this function to be activated.
This feature can be disabled using parameter P08. See “6.6 USER PARAMETERS”.
6.8 LEGIONELLA PROTECTION
If Legionella protection is activated, once a week the DHW temperature is raised to the maximum allowed. By
default protection against Legionella it is disabled. This function can be activated with parameter P10. See " 6.6
USER PARAMETERS ".
6.9 AUTO HEATING REGULATION.
It is possible to regulate the temperature at which the boiler drives the water heating circuit depending on the
outdoors temperature. This method of regulation provides maximum comfort as it anticipates changes in the
thermal needs of the house. The room thermostat continues to regulate the temperature inside the house.
To activate this mode of heating, the installer will need to connect an external temperature sensor (not supplied)
and activate the P05 and P11 parameters.
