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.
Parameters menu from P16 – P18 are only accessible for DHW & central heating boiler (P00=1).
ECO SMART.
TCON. Maintenance consumption connection time. Factory pre-set.
TSCON. Time interval between maintenance consumption. Factory pre-set
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 if this
temperature has not been reached in the last 7 days. By default protection against Legionella it is disabled. This function can
be activated with parameter P10. See " 6.6 USER PARAMETERS".
