In the HQM menu, up to seven internal heat quantity
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 adjusted
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 quantity balan-
cing. 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 allocated relay is active.
In the adjustment channel Fluid type, the heat trans-
fer fluid must be selected. If either Propylene glycol
