Note: The mounting place and the pulse value of flow sensors
with pulse output must correspond to the in the calculator set val-
ues (see LOOP 2).

Pulse value
Note: At a heat meter calculator or combined heat / cold meter
calculator the mounting place of the flow sensor cold side is equiv-
alent to return. The mounting place of the flow sensor hot side is
equivalent to flow.
Note: At a cooling meter calculator the mounting place of the
flow sensor hot side is equivalent to the return. The mounting place
of the flow sensor cold side is equivalent to flow.
Attention: Calculators with one-time adjustable pulse value and
adaptable mounting place being characterized by:
Attention: At calculators with one-time adjustable pulse value,
the pulse value must be adjusted during commissioning in ac-
cordance with the flow sensor and the mounting place must be
checked!
As long as the pulse value has not been set, the calculator does
not cumulated energy and volume.
The mounting place can be adapted and is fully locked by entering
the pulse value.
