can be used any time for changing to the status or main menu of the
controller in order to carry out adjustments.
When the screed drying function has been successfully completed, the corre-
sponding heating circuits change to their operating mode.
Screed drying is automatically deactivated. The chimney sweeper function is acti-
vated in all heating circuits.
Note:
Make sure the heating circuits are supplied with heat from a heat source
(backup heating).
Note:
If an SD card has been inserted into the slot, a screed protocol will be
generated.

11 HQM
In the HQM menu, up to 2 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 sub-menu opens in which all adjustments required for the heat quantity meas-
urement can be made.
If the Flow rate sensor option is activated, an impulse 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 im-
pulse rate must be adjusted in that menu as well.
If the Flow rate sensor option has been activated and a relay allocated, heat quanti-
ty measurement will only take place when the allocated relay is switched on.
If the Flow rate sensor option is deactivated, the controller calculates the heat
quantity by means of a fi xed fl ow rate value (heat quantity balancing). The heat
quantity balancing (estimation) uses the difference between the fl ow and return
temperatures and the entered fl ow rate (at 100 % pump speed).
Î Read the fl ow rate (l / min) and adjust it in the Flow rate channel.
Î Adjust the antifreeze type and concentration of the heat transfer fl uid in the
channels Fluid type and Ratio.
