4.1.6 Heat quantity balancing
OHQM:Heat quantity measu-
rement
Adjustment range: OFF ... ON
Factory setting: OFF
A heat quantity balancing is possible for the basic systems
(Arr) 1, 3, 4 and 5 in conjunction with a flowmeter. You
just have to activate the option heat quantity balancing in
channel OHQM.
The volume flow readable at the flowmeter (l/min) must
be adjusted in the channel FMAX. Antifreeze type and
concentration of the heat transfer medium are indicated on
channels MEDT and MED%.
Type of antifreeze:
0 : water
1 : propylene glycol
2 : ethylene glycol
3 : Tyfocor
®
LS / G-LS
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 indication
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, symbol
is permanently shown on the display. The SET (3) button
must pressed for approx. 2 seconds in order to get back into
the RESET-mode of the counter. The display-symbol
is
blinking and the value for heat quantity will be set to 0. In
order to finish the RESET-procedure, the button
must
be pressed in order to confirm the data.
In order to interrupt the RESET-procedure, no button
should be pressed for about 5 seconds. The controller re-
turns automatically into the indicaton mode.

4.1.5 Operating hours counter
The operating hours counter adds up the solar operating
hours of the respective relay (h P / h P1 / hP2). Full hours
are shown on the display.
After the operating hours are added up, they can be reset.
As soon as one operating hours channel is selected, symbol
is permanently shown on the display. The button SET
(3) must pressed for approx. 2 seconds in order to get back
into the RESET-mode of the counter. The display-symbol
is blinking and the operating hours will be set to 0. In
order to finish the RESET-procedure, the button
must
be pressed in order to confirm the data.
In order to interrupt the RESET-procedure, don’t press any
button for about 5 seconds. The controller returns auto-
matically into the indication mode.
