Terminals and fuses for power adjustment, 9 kW
The mains connection is made via the premounted
connecting cable with a Cekon-type plug to the cor-
responding separately secured Cekon-type socket
(not included, on-site device).
18 kW version - 32 A socket, 9 kW version - 16 A socket.
An external control is connected to terminals 14 to 19 (9 kW, Fig. 7) or 21 to 26 (version 18 kW, Fig.
6). A fragrance container is placed on terminals 20 and 21 (9 kW) or 27 + 28 (18 kW).
The control lines are potential-free towards the supply lines with the exception of the protective
conductor.
Water level control
The water level and the water filling are automatically monitored and controlled by the built-in
level sensor.
Each time the mains voltage is switched on or when the connected external controller is switched
on, a self-test of the level sensor is carried out.
The self-test lasts about 30 - 270 seconds. If the maximum water level is already being measured,
the water tank is emptied and refilled to check the function of the float switch. This process will
take a few minutes. Afterwards the device is ready for operation. This process is part of the normal
operation; the status LED on the device also lights up permanently.
