4.1.7 Heat quantity balancing
OHQM
:Heat quantity
balancing
Adjustment range:
OFF ... ON
Factory setting:
OFF
A heat quantity balancing is possible for all systems in con-
junction with a flowmeter. You just have to activate the op-
tion heat quantity balancing in the channel OHQM.
The volume flow readable at the flowmeter (l/min) must be
adjusted in the channel FMAX. Antifreeze type and con-
centration of the heat transfer medium are indicated on the
channels MEDT and MED%.
Type of antifreeze:
0 : water
1 : propylene glycol
2 : ethylene glycol
3 : Tyfocor

The heat quantity transported is measured by the indica-
tion of the volume flow and the reference sensor of feed
flow S1 and return flow T-. It is shown in kWh-parts in the
indication channel kWh and in MWh-parts in the indica-
tion channel MWh. The sum of both channels form the
total heat output.
The heat quantity added up can be reset. As soon as one
of the display channels of the heat quantity is selected, the
symbol is permanently shown on the display. The
button SET (3) must be pressed for approx. 2 seconds in
order to get back into the RESET-mode of the counter. The
display-symbol is flashing and the value for heat
quantity will be set to 0. In order to finish the RESET-
procedure, the button must be pressed for con-
firmation.
In order to interrupt the RESET-procedure, no button
should be pressed for about 5 seconds. The controller
returns automatically into indication mode.
