2.2SWITCHING THE CONTROL UNIT ON AND OFF
NOTE: For putting the unit into operation and taking the unit out of operation please follow the procedures described in the installation and operating instructions for the Nortec MH.
Switching the MH control unit on
The control carries out a system test, during which all the LEDs light up and the opposite display is shown. If a failure occurs on the system test, a corresponding error message is shown in the display.
After the system test the control is in normal operation mode. The display shows the standard operating display. Note: The contents of the standard operating display depends on the type (MHTC Flow, MHTC Reflow), the actual operating status and on the configuration of the Nortec MH and can differ from the opposite display.
Switching the MH control unit off
The display goes out. On models MHB Reflow and MHTC Reflow the drain valve opens and the water tub empties.
Note: The different hygiene functions (regular draining, flushing of the supply line, etc.) remain active also in times without humidification / cooling demand, the control unit should only be switched off for maintenance or, troubleshooting, or to disable completely operation (as in seasonal shutdown).
