# Description
U00 When using outdoor sensor, above this parameter
value of outside temperature, the boiler senses the
season as summer and does not activate central
heating although there is demand. Summer-winter
switching has a hysteresis of ±1ºC.
i.e: When this parameter is adjusted to 20ºC, the boiler
switches to summer mode at 21ºC and switches back
to winter mode at 19ºC.
U01 This value is used when only outside sensor is
connected to the boiler (No Opentherm room
thermostat connection). The parameter heating slope is
important to adapt the weather compensation to the
individual heating system, the building and the thermal
insulation. The heating slope can be adjusted from 0
to 40. The heating slope needs to be increased to
increase the boiler central heating set temperature.
Colder regions require a higher heating slope value.
Note: To activate weather compensation, the heating
slope value must be higher than "5".
U02 Enabling / disabling central heating ECO mode.
1 = enabled, 0 = disabled
# Description
U03 Enabling / disabling domestic hot water comfort mode.
1 = enabled, 0 = disabled
U04 Domestic hot water set value (same function that can
be done via the right dial when domestic hot water
mode is enabled).
U05 When On-Off room thermostat and outdoor sensor are
both connected, this parameter value is the virtual room
temperature setpoint when there is a heat demand.
U06 When On-Off room thermostat and outdoor sensor are
both connected, this parameter value is the virtual room
temperature setpoint when there is no heat demand.
Note: For this parameter value to be active, reducing
mode has to be enabled by your service agent,
otherwise central heating mode will not be activated
when there is no heat demand.
U07 When On-Off room thermostat is connected and
outdoor sensor is not connected, this parameter value
is the central heating water temperature setpoint when
there is a heat demand.
U08 When On-Off Room thermostat is connected and
outdoor sensor is not connected, this parameter value
is the central heating water temperature setpoint when
there is not a heat demand.
Note: For this parameter value to be active, reducing
mode has to be enabled by your service agent,
otherwise central heating mode will not be activated
when there is no het demand.
U09 If parameter is 1, comfort mode preheating will depend
on the user record. It will preheat the water according to
the previous day user records.
If parameter is 2, comfort mode preheating will be
independent of the user record, and at the highest
comfort level (3-star comfort according to EN13302).
If parameter is 24, comfort mode preheating will be
independent of the user record.
Note: If you increase the comfort level, the energy
consumption increases.

room thermostat during night mode. Only visible in case
