Page 27: Appendix 1. Commissioning
10.2. Parameterisation for commissioning The ENA 7-30 comes with a pre- parameterized control. As this control offers a wide range of possibilities, you will have to set operating parameters so that they will be adapted to the concrete operating conditions of your heating/cooling system. -
Page 28: Appendix 2. Items Of The Hardware And Parameter Menu
11. Appendix 2. Items of the hardware and parameter menu 11.1. Operating modes The operator can operate the system in the fast and normal de-aeration mode. Service personnel have also access to hand mode, and can carry out a leakage test. This leakage (vacuum) test can also be used to test the ability to operate the pump. -

11.2.3. Filling off The ENA 7-30 unit operates solely as an automatic de-aeration unit. 11.3. Monitoring It is the primary purpose of the monitoring functions to detect errors in the system at an early point of time and to protect the system components to the largest possible extent by means of appropriate signals or by automatically shutting down the system. - Page 30 (if activated), and an error message will be initiated. Negative values mean that the permissible treated quantity (capacity) in litres has been exceeded. The ENA 7-30 continues to operate in such a case.
