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

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.
