555. 4 On: System frost protection On (factory setting)
555. 4 Off: System frost protection OFF
Explanations on frost protection are given on Pages 44/45.
None of the other bit settings should ever be readjusted!
558.0 Off: Header function OFF (factory setting)
558.0 On: Header function On
When it is necessary for hydraulic reasons, a header pump can be
connected (terminal X1; output M5).
558.1 Off: Lightweight building (factory setting)
558.1 On: Heavy building
The heat storage capacity of the building is taken into consideration
beginning on the type of building. With lightweight building, the control
reacts more quickly to variations in the outer temperature than for heavy
buildings.
558.2 Off: Hot-water thermostat OFF (factory setting)
558.2 On: Hot-water thermostat ON
With the factor setting, this function is not activated. When a tank control
is connected instead of a tank sensor, set bit 2 to 1 (On). This tank control
can be connected to terminal X6/B3 instead of the tank sensor B3. The
tank control must be equipped with high quality contact material (e.g. gold
contact) due to the switching voltage of 5 V DC!
None of the other bit settings should ever be readjusted!
561.0 Off: Heating circuit pump in stages (factory setting)
561.0 On: Heating circuit pump modulating
561.1 Off: Delta T limit OFF
561.1 On: Delta T limit ON (factory setting)
561.2 Off: Delta T control OFF
561.2 On: Delta T control ON (factory setting)
In program No. 561, it is only permissible to change bits 0, 1 and 2, when
then pump function is modified according to the application schematics or
the PWM pump is replaced by a stage pump! See also Service note on Page 48.
561.3 On and 561.4 Off: Medium system volume (factory setting)
561.3 Off and 561.4 Off: Small system volume
561.3 Off and 561.4 On: Large system volume
A medium system volume corresponds to that for a single family house.
Small system volume corresponds to that for a flat heater.
Larger system volume correspond to that of a multiple family house.
561.5 Off: Delta T control in reduced mode OFF (factory setting)
561.5 On: Delta T control in reduced mode ON
When bit 5 = 0, the pump is generally operated at the minimum pump
speed setting program No. 538 (NqmodMin) in the reduced mode.
When the heat requirement is too low in poorly insulated buildings, this
function should be activated (bit 5 =1) so that the pump can operate in the
same manner as in the standard mode!
None of the other bit settings should ever be readjusted!
In program No. 598 (LmodRgVerz), the burner output can be set at which
the EUROCONDENSE PLUS operates during the delay time set in
program No. 547 (ZreglVerz).
This output must never be changed!
