Flow monitoring
If during normal operation the flow temperature rises above 90°C a warning indication will be shown.
If the energy productivity measurement option is deactivated, the temperature difference between collector and storage
tank is checked. If the temperature differential exceeds 60K + dTmax an error message will occur, as under normal system
operation where the pump is running, large temperature differences would not normally be seen.
If the energy productivity measurement option is activated, the flow rate is checked, if no flow is detected for 15 minutes an
error message will be seen (Applicable if Flow Meter fitted).
NOTE: these error conditions will automatically reset after a short period of operation once normal flow/temperature
conditions are restored.
System protection function
The system protection function switches the system off if the “maximum collector temperature” is exceeded by 10K. As soon
as the temperature drops below the “maximum collector temperature”, the system restarts. This function has priority and is
always active, regardless of whether the collector protection is on or off.
Frost protection
This function can be switched on or off by using item 11 in the “Basic adjustments” menu. The start temperature can be
adjusted with item 13. Furthermore, a frost protection sensor can be selected (T1-T6, point 12).
If the measured value is lower than the start temperature, the solar pump is activated until the adjusted frost protection start
tempe5K is reached. The minimum runtime of the pump is 5 minutes.
For safety reasons the function is deactivated if the temperature of the priority storage falls below 5ºC.
Energy productivity measurement
For the purposes of energy productivity measurement (solar gain), a sensor on the collector return line and an optional flow
meter are required. The yield value is calculated from the values of the temperature difference between the collector and
collector return line and the value measured by the flow meter. This function is switched on and off in the “Basic settings”
menu.
Operating hours meter
When the storage tank is being charged by a pump, the operating hours meter records for each separate pump.
The number of operating hours can be read in the “info” menu. This may be reset to ‘0’.
