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.

that the clock does not continue to run if the mains voltage is interrupted, and must therefore be reset.
