Energy metering
OHQM
: Energy metering
Adjustment range: OFF / ON
Factory setting: OFF
If OHQM is activated, the heat quantity gained can be
calculated and displayed. Energy metering is possible if a
flowmeter is used. To enable energy metering, proceed as
follows:
Î
Read the flow rate (l/min) from the flowmeter at maximum
pump speed and adjust it in the
FMAX
channel
Î
Adjust the heat transfer fluid and the concentration of the
antifreeze in the channels
MEDT
and
MED%
.
FMAX:
Flow rate in l/min
Adjustment range: 0.5 ... 100.0
in steps of 0.5
Factory setting: 6.0
MEDT:
Heat transfer fluid
Adjustment range: 0 ... 3
Factory setting: 1
MED%:
Antifreeze ratio
in Vol-% (MED% is hidden
when MEDT 0 or 3 is used.)
Adjustment range: 20 ... 70
in steps of 1 %
Factory setting: 45
Heat transfer fluid:
0 : Water
1 : Propylene glycol
2 : Ethylene glycol
3 : Tyfocor
