Initializing The Induction Unit
By PC Or Laptop
The initialization of the CU (RTCS) sensors (excluding all
WOK models), as well as adjustments of the pan detection
and power performance, can be performed by means of
the hyperterminal program. Please refer to Section 9 “IR
Interface” for instructions on how to use the hyperterminal
program The following adjustments must be done in the
hyperterminal program: 2400bps, 8bit, no parity, 1 stop bit,
hardware protocol.
IMPORTANT NOTE: When replacing the power board and
or induction coil with RTCS sensors, you must reset all
parameters.
IMPERATIVE! Pay close attention to whether you receive a
feedback signal from the PC or Laptop after every change.
This will be your signal that the change has been accepted
successfully.

Change Of The Parameters
1. Connect the RS232 connection cable to the
PC/Laptop and straighten the IR-adapter to the left lower
corner of the ceran glass. For counter top cookers, refer to
Section (9) gure #3 for correct IR adapter positioning. For
all Wok cookers, you will be required to remove the top
wok bowl assembly. Place the IR-adapter in the left hand
corner directly over the rectangular opening located on
the metal sheet with ferrit stripes. Please refer to Section
(9) gure #4 for Wok cooker IR adapter positioning.
2. Start HT2400 (see chapter 9) and turn unit on!
3. Input “12345” and the mode of adjustment will now
