11 HQM
In the
HQM
menu, up to seven internal heat quan-
tity measurements can be activated and adjusted.
By selecting the menu item
New HQM
, a new heat
quantity measurement can be activated.
a menu opens in which all adjustments required for
the heat quantity measurement can be made.
If the
Flow rate sensor
option is activated, the im-
pulse input or, if available, a Grundfos Direct sensor™
can be selected. Grundfos Direct sensors™ are only
available if they have been previously registered in
the In-/outputs menu. the impulse rate must be ad-
justed in that menu as well.
If the
Flow rate sensor
option is deactivated, the
controller calculates the heat quantity by means
of a fixed flow rate value. this is called heat quan-
tity balancing. For this purpose, the flow rate must
be read from the flowmeter at 100 % pump speed
and adjusted in the adjustment channel
Flow rate
.
In addition to that, a
Relay
must be allocated. Heat
quantity balancing is in effect whenever the alloca-
ted relay is active.
