USE OF BOOST FUNCTION
The "BOOST" mode gives you the possibility to generate DHW faster and in excess quantity in the case of urgent or
occasional need for DHW (family visit, the sports team of your children comes for a shower, etc.) To activate the "BOOST"
cycle, select the menu parameter "Boost" and the value "on". During the "BOOST" cycle the HP and the supplementary
heating will operate simultaneously for 1 hour maximum or until "Tmax" is reached. If you need still more DHW you have
to activate the boost function again.
USE OF EXTERNALLY CONTROLLED DHW PRODUCTION
You can control the DHW production externally by means of a potential free contact (energy counter, external timer, etc.).
This function gives you the possibility to generate DHW in a specific period (e.g. off-peak tariff production, acoustic
comport preference, etc.).
Important!
Do not use an external timer to cut the power supply, use instead the externally controlled DHW production, by wiring the
external potential free contact to terminal block CN5 connector 5 and 6. "See page 12 for wiring diagram".
Please note that the external contact or timer must have gold-plated contacts due to low current operation. When the contact
is "closed" the DHW production is locked, while the frost protection is activated. When the contact is open, the DHW HP
operates in the selected operating mode.
At the "T2min" temperature level the HP will resume working, in order to protect the device and the installation against
frost. Should the temperature fall below "T2 min" -1°C, the supplementary heating will be released. If the temperature falls
further below "T2 min" -3°C the heat pump will also start. When the temperature reaches "T2 min" +1°C the DHW
production will be locked again.
MAINTENANCE AND CARE
Your DHW HP is working automatically. Nevertheless it needs some care and maintenance. We recommend to sign a
service contract with your installer or to include it into an existing service contract with your specialized service provider.
CARE BY THE END USER:
The DHW HP does not need specific care or maintenance by the end-user. Nevertheless the responsibility of the user is:
To check the security valve regularly
•
To check the displays for alarms.
•
To clean air in- and outlet from dust
•
To check the installation for leakages
•
To check and clean the drain connector/hose.
•
To inform the installer if necessary.
