Other possible problems are:
• The control unit is working fine, but
the heater does not turn on. Check the
electricity supply to the heater. Check that
the wires for the sensors are placed into
the correct terminals in the control unit.
• The control unit cannot display the relative
humidity* (only when the combined
sensor is installed). The combined sensor
cannot be recognised. The wires for the
sensor are placed in the wrong terminals.
• Control unit doesn’t turn on and clicking
sound can be heard. Check that fuse
F1 (near transformer) is tightly in fuse
holder.
• User presses a button and “----“ is shown
in the display. This indicates that the key
pad is locked. Unlock the buttons by
pressing up and down arrow keys at the
same time for more than 5 seconds. A
high beep will confirm the activation and
the deactivation.
• If error E4 or E6 is displayed, there is a
problem with the bench sensor. If only one
sensor is installed, the steamer cannot be
used. The user can confirm the error by
pressing the on/off button, after which
the heater will function normally, but the
steamer cannot be used.
• The user switches the steamer on and
“dry” is displayed immediately. Check that
the “empty” and “tank level” terminals
from the heater are connected with the
“empty” and the “tank level” in the Power
Controller.
• The steamer is on and “dry” is displayed,
even though there is plenty of water
in the tank. Make sure that terminals
“empty” and “tank level” are correctly
connected to the right terminals in the
Power Controller.
• The steamer is switched on and “dry”
is displayed immediately. Make sure that
the “WB” terminal from the heater is
connected with the “tank level” in the
Power Controller. Switch On DIP switch
number 7 (empty) to disable empty
function.
• When the user turns the steamer on and
“Fill” is displayed continuously, the wiring
needs to be checked. Switch On DIP
switch number 7 (empty) to disable empty
function. In addition, the “WB” terminal
from the heater needs to be connected
to the “tank level” in the Power Controller.
