The EUROCONDENSE PLUS boiler is factory-set for operation and
requires no changes as a rule.
However, a few parameters (see
specialists), serve for adaptation to the specific heating system and should
be optimized.
Note: The parameters marked with
exceptional cases when absolutely necessary!
A room control module RRG or service module RRG (optional extra) is
required for adjusting the parameters.
This ensures efficient hot-water charging. The boiler temperature setting is
increased when hot water is required. Increase: Quicker charging time;
greater overshoot
Reduction: Slower charging time; less overshoot
Increasing the flow temperature achieves a constant mixer flow
temperature.
Increasing: Mixer flow temperature undershoot is avoided
Lowering: Mixer flow temperature undershoot possible
The automatic S/W switchover is a function with a long-term effect which
switches off the heating during the summer when the outdoor temperature
is higher than the S/W switchover temperature set here for a longer period
of time and switches it back on only when the outdoor temperature is
below the value set here for a longer period of time.
- By pressing button on heating circuit module HKM (Fig. 2)
- With automatic S/W switchover via outdoor temperature.
When operated with the room control module RRG, this module takes over
automatic S/W switchover for the appropriate heating circuits (see RRG).
When operated with the heating circuit module HKM and other
EUROCONTROL controllers, the automatic S/W switchover feature
(param. No. 516) is effective.
The automatic S/W switchover feature operates with a switching difference
of ± 1 K. If a temperature of equal to or greater than 30 °C is set, in
program No. 516, switchover is not accomplished!
