Sensor Calibration
Deviations in the temperature values displayed, for example. due to cables which are too long or sensors which are not posi-
tioned optimally can be compensated for manually here. The settings can be made for each individual sensor in steps of 0.5 °C.
Settings are only necessary in special cases at the time of initial commissioning by the specialist. Incorrect meas-
urement values can lead to unpredictable errors.
Commissioning
Starting commissioning help guides you in the correct order through the basic settings necessary for commissioning, and
provides brief descriptions of each parameter in the display. Pressing the ‚esc‘ key takes you back to the previous value so you
can look at the selected setting again or adjust it if desired. Pressing ‚esc‘ more than once takes you back to the selection mode,
thus cancelling the commissioning help see " Commissioning help " on page 14
May only be started by a specialist during commissioning! Observe the explanations for the individual parameters in
these instructions, and check whether further settings are necessary for your application.
Factory Settings
All settings can be reset, returning the controller to its delivery state.
All of the controller‘s parametrization, statistics, etc. will be lost irrevocably. The controller must then be commissioned
once again.
Time & Date
Serve to set the current time and date.
For system data statistics it is essential for the time to be set accurately on the controller. Please note that the clock
continues to run for about 24 hours if the mains voltage is interrupted, and afterward must be reset. Improper oper-
ation or an incorrect time may result in data being cleared, recorded incorrectly or overwritten. The manufacturer
accepts no liability for the recorded data!
Starting aid
For some solar systems, in particular for vacuum tube collectors, the measurement recording on the collector sensors may be too
slow or imprecise, because the sensor is often not on the warmest spot. With an activated starting aid, the following procedure
occurs: If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar cir-
culation pump will be turned on for the set “purging time” so that the medium to be measured is transported to the collector
sensor. If there is still no normal switching condition through this, there will be a 5 minute block time for the start wizard function.
This function should only be activated by a technician if problems occur with the measurement recording. Observe in
particular the instructions from the collector manufacturer.
The menus "Purging time" and "Increase" are only displayed when the starting aid function is set to "On".
Purging time
If the temperature on the collector sensor increases within a minute by the value defined under “increase”, the solar circulation
pump will be turned on for the set “purging time” so that the medium to be measured is transported to the collector sensor. If the
set ΔT is not reached, a 5-minute circulation pause time for the starting aid function will apply.
Increase
If the temperature at the collector reaches within a minute the value defined, the solar pump is turned on for the duration of the
purging time.
Global radiation sensor
With the global radiation sensor, a start-up operation can be triggered depending on the solar
radiation. If the set radiation intensity exceeded at the sensor, the start-up aid is activated and the solar pump is switched on for
the set rinsing time. If within this time no start condition is reached, the start-up function is blocked for the set time.
Radiation sensor
The sensor input can be defined here, to which the global radiation sensor is connected.
