3.2.2 Flow monitoring

If the energy productivity measurement option is deactivated, the temperature difference between collector and storage tank is checked.

If it exceeds the amount of (60K + dTmax), it is then interpreted as an error because in the case of normal system dimensioning and a pump switched on such large differences cannot take place.

If the energy productivity measurement option is activated, the flow amount when the pump is switched on is checked. If for 15 minutes no flow is recognised it is evaluated as an error.

Error message is automatically reset after eliminating the failure.

3.2.3 Collector protection / Re-cooling

 

 

This function can be switched on/off in the “Basic settings”

 

 

menu.

 

 

High temperatures can destroy antifreeze liquids.Therefore,

 

 

the maximum collector temperature should be restricted.

 

 

When all storages have been loaded to the limit, the solar

 

 

pump is switched off. If the collector temperature rises

 

 

above“T collector max”, the solar pump is switched on,

 

 

until the collector temperature drops by 10K. Part of the

 

 

energy is lost in the pipes, the rest is loaded in the storage,

 

 

which results in increasing the storage temperature above

 

 

the adjusted maximum storage temperature. For security

 

 

reasons the function will be interrupted if the storage

 

 

reaches 95ºC.

 

 

If the storage temperature is bigger TStmax+2K and the

 

 

collector temperature is 10K belowTSt, then the re-cooling

 

 

function is activated.The redundant storage energy will be

 

 

released through the collector in order to assure reserves

 

 

for the next loading cycle.

 

 

The re-cooling ends when TSt drops below the value “re-

 

 

cooling till…” in the “Basic settings” menu, point 3, or

 

 

when the collector temperature >= the storage

 

 

temperature – 2K.

 

 

The re-cooling function can be active only when the

 

 

collector protection function is on.

3.2.4 Systemprotection 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 is started up again.This function has higher priority and is always active, regardless of whether the collector protection is on or off.
