PRIMARY FACTOR
[20]
Compensation factor to affect the sensitivity of the hot water control in
dependency of the buffer cylinder temperature. If the compensation
factor is set to 0, compensation is not active and that also applies to
when neither primary flow sensor nor buffer cylinder sensor are
connected.

ADAPTATION
VALUES
Start values for calculation of pump power. For all 10 tapping slots start
values are set. They are the base of calculating the required pump
force. The actual temperatures and tapping volumes are incorporated
in the calculation. The individual values can be examined and changed
by selecting the respective sub-menus. If not all slots are reached
during controlled tapping while commissioning the system (chap. 5.6),
the adaptation values can be set directly. The power of the pump
continuously increases over the ten tapping slots. Each slot must have a
higher value than the previous one.
ADAPT. VALUE 1
60 °C 01 [08]
Adaption value of the first tapping slot. On the left the current hot water
temperature is shown. In the centre you can see the tapping slot
currently in use. On the right, the momentary adaptation value can be
seen. In order to make an adjustment, the adaptation value (display:
top) related to the current tapping slot (display: centre) should be
selected. Increasing this value will also increase the initial pump power
of the slot. Setting the value to high results in risk of scalding, since the
controller only starts with the adaptation after 10 s and then reduces the
pump power until the set water temperature is reached.
