7.10.2.1 Detailed Explanations of User Parame-
ters
U00: When using outdoor sensor, above this parameter value
of outside temperature, boiler senses the season as summer
and not activate central heating although there is demand.
U01: This value is used when only outside sensor is connect-
ed to the boiler (No Opentherm RT connection). The param-
eter heating slope is important to adapt the weather compen-
sation to the individual heating system, the building and the
thermal insulation. The heating slope can be adjusted from 0
to 40. The higher the value heating slope, the higher the boiler
central heating set temperature.
Note: To activate Weather compensation, heating slope value
must be higher than "5".
U02: Enabling / disabling Central Heating ECO mode.
1 = enabled, 0 = disabled
U03: Enabling / disabling DHW Comfort mode.
1 = enabled, 0 = disabled
U04: Domestic hot water setvalue (Same function that can be
done via right dial when DHW mode is enabled).

U05: When On-Off Room thermostat and outdoor sensor are
both connected, this parameter value is the virtual room tem-
perature 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 tem-
perature setpoint when there is no heat demand.
Note: For this parameter value to be active, reducing mode
have to be enabled by your service agent, otherwise central
heating mode will not be activated when there is no heat de-
mand.
U07: When On-Off Room thermostat is connected and out-
door sensor is not connected, this parameter value is the cen-
tral heating water temperature setpoint when there is a heat
demand.
U08: When On-Off Room thermostat is connected and out-
door sensor is not connected, this parameter value is the cen-
tral heating water tempearture setpoint when there is not a
heat demand.
Note: For this parameter value to be active, Reducing mode
have to be enabled by your service agent, otherwise central
heating mode will not be activated when there is no het de-
mand.
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.
U10: Room temperature setpoint used by Daikin Opentherm
RT during "Night mode". Only visible in case Daikin Open-
therm room thermostat is connected.
