3.1.6 Heat quantity balancing
OHQM:Heat quantity balan-
cing
Adjustment range: OFF ... ON
Factory setting: OFF
A heat quantity balancing is possible for all systems in
conjunction with a flowmeter. You just have to activate the
option 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
concentration 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
®
LS / G-LS
FMAX:
Volume flow in l/min
Adjustment range 0 ... 20
in steps of 0,1
Factory setting 6,0
kWh/MWh:Heat quantity
in kWh / MWh
Display channel
MEDT: Type of antifreeze
Adjustment range 0 ... 3
Factory setting 1
MED%: Concentration of
antifreeze in (Vol-) %
MED% is blinded out by
MEDT 0 and 3.
Adjustment range 20 ... 70
Factory setting 45
The heat quantity transported is measured by the indication
of the volume flow and the reference sensor of feed flow
S1 and return flow S4. It is shown in kWh-parts in the in-
dication 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, 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 confirmation.
In order to interrupt the RESET-procedure, no button
should be pressed for about 5 seconds. The controller re-
turns automatically into indication mode.
3.1.7 ∆T-regulation
Please note: Switch-on temperature difference DO must
be at least 2 °Ra higher than the switch-off temperature-
difference DF.
DT O:
Switch-on temperature
Adjustment range
2,0 ... 40,0 °Ra
Factory setting 12.0
DT F:
Switch-off temperature diff.
Adjustment range
1,0 ... 38 °Ra
Factory setting 8.0 °Ra
Primarily the controller works in the same way as a standard
differential controller. If the switch-on difference (DT O)
is reached, the pump is activated. If the adjusted switch-off
temperature is underrun (DT F), the controller switches-
off.
