F 7.8.5 -
∆
T Offset
Since the calculation of the heat metering is based on the temperature of the collector and storage where
measuring takes place, a possible deviation from the
fl
ow and return temperature can be compensated with
this value.
Example:
Displayed collector temp. 40 °C, measured
fl
ow temp. 39 °C, displayed storage temp. 30 °C,
measured return temp. 31 °C means a setting of -20 %
(Displayed
Δ
T 10K, actual
Δ
T 8K => -20 % correction value)
Setting range: -50 % to +50 % /default setting: 0 %
F 7.9 - Start aid function
With some solar systems, especially with vacuum tube collectors, it may occur that the measurement value
acquisition at the collector sensor occurs too slowly or too inaccurately because the sensor is often not at the
hottest location. When the start help is activated the following sequence is carried out:
If the temperature at the collector sensor increases by the value speci
fi
ed under
„Increase”
within one
minute, then the solar pump is switched on for the set
„Purging time”
so that the medium to be measured
can be moved to the collector sensor. If this still does not result in a normal switch-on condition, then the start
help function is subject to a 5-minute lockout time.
Start help setting range: on, off/default setting: off
Purging time setting range: 2-30 sec./default setting: 5 sec.
Increase setting range: 1 °C - 10 °C/default setting: 3 °C/min.
This function should only be activated by a specialist if problems arise with acquisition of
measurement values.
F 7.10 - Daylight saving time
When this function is active, the controller’s clock changes automatically to and from DST (DST, Daylight
Savings Time).
