In systems with 2 or more stores, the corresponding
number of seperate menu items (Store1 to Store5)
is displayed instead of Store.
For each store, an individual ∆T control, a set and
a maximum temperature, the priority, a hysteresis,
a rise value, a minimum runtime and a minimum
pump speed can be adjusted.
In multi-store-systems with diering Store set / Ma-
ximum store temperatures, all stores are loaded up
to their Stset temperatures rst (according to their
priority and the store sequence control). Only when
all stores have exceeded Stset will they be loaded
up to their Stmax temperatures, again according to
their priority and the store sequence control.
