Operational Information

During normal operation, select one of the MMI information screens:
• Display Values (menu 24)
• Display All Values (menu 19)
• Display Timer/Sequence (menu 23)
• Display Twin Values (menu 36) (Twin units only)
Refer to paragraphs 5.2.9, 5.2.10, 5.2.11 and 5.2.12. These menus provide
continuous information about current operating conditions, e.g., output power,
voltages and current values. The output frequency is displayed in the F7 Status
information, and in the "Display Values" and "Display Twin Values".
Regardless of which menu is selected, each screen contains a footer displaying
alarms, indications/limitations and operational messages. The various messages are
described in paragraph 5.1.1.
6.3.2

Control Functions

Sequence
The sequence function enables the operator to run specific heating sequences. Eight
different sequences can be programmed in the Sequence Menu (menu 4); refer to
paragraph 5.2.6. If the sequence function is activated, the sequence (program no.)
selected in the Sequence Menu will start each time a POWER ON signal is given.
Note that in remote control, the sequence program to be started is selected via the
external interface.
Timer
The timer function enables the operator to run the unit at a specific time interval. The
duration of the interval is selected in the Timer Menu (menu 7); refer to paragraph
5.2.5. If the timer function is activated, the time interval starts each time a POWER
ON signal is given. This means that the output power is on from the moment a
POWER ON signal is given until the time interval has elapsed.
Water Auto Shut-off
Activating the "Water auto shut-off" function automatically closes the water flow 20
seconds after the output power is turned off. This cuts down on water consumption.
To turn the power on again, press the POWER ON button and hold it for a minimum
of 1.6 seconds until the output power comes on. The reason for this time delay is to
make sure that the water is flowing before any heat develops.

When the cooling water temperature is low at the same
time as the ambient temperature is high, activate the
"Water auto shut-off" function in the Activate Menu to
avoid condensation on pipes, etc., inside the unit.
