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.
