Set Parameter 26 room setpoint ramp to OFF.
►
Set parameter 41 switch-on optimisation to 1 = adaptation off
or with connected room sensor to 2 = adaptation on.
If parameter 41 switch-on optimisation is set to 1, parameters 42
min. pre-heating time and 43 max. pre-heating time are not
required.
If parameter 41 switch-on optimisation is set to 2, parameters 45
no room sensor and 46 pre-heating time at 0°C are not required.
Parameter 41 switch-on optimisation, 03 adaptation restart
If a controller is exchanged or structural changes are made, e.g.
improvement in insulation, replacement of windows etc., adaptation
must be restarted.
Parameter 42 min. pre-heating time
A pre-heating time takes place before the set heating cycle, e.g. 6
a.m. This is only possible with a room sensor. Without a room
sensor, parameter 45 is active without a room sensor.
Parameter 43 max. pre-heating time
This parameter setting limits the duration of pre-heating, which is
set to 5 hours at the factory. This is only possible with a room
sensor. Without a room sensor, parameter 45 is active without a
room sensor.
Param
e
ter 44 min. jump back temperature
This parameter setting specifies the outside temperature up to
which the adaptation works. If this parameter is set to 5°C, for
example, adaptation is active up to 5°C and deactivated starting
with an outside temperature of 6°C.
Parameter 45 without room sensor
The set room temperature is increased by a specific amount, e.g.
1°C, during switch-on optimisation so that the heat generator gets
a higher temperature setpoint and thus the heating circuit can
heat up faster.
