Hafele HC-M773A, Installation Operating & Maintenance Manual

for hot cooking zones “H” are displayed in alternation with “ 

0” and the synchronously display dot. The display dots on the 

cook  top displays  flashes up every second (0.5 sec.off,  0.5 

sec.  on). Electronics  remains  activated  for  20 seconds. If 

there is no cooking level or timer selection done in this period 

the electronics automatically resets to the Off-mode by releasing 

a signal tone.

The TC may only be switched on by pressing the power key as 

sole input In case of an other key is pressed (single or in parallel 

with the power key ), the control unit is not switched on.

In  case  of  an  active  “Child Lock  Function”  when  switching 

POWER ON, all cooking zone displays show “L” for LO CKED . 

Possible optic warnings for hot cooking zones [H] are displayed 

in alternation with [L] (H-ON= 0.5 sec; L-ON = 1.5sec).

By pressing the ON/OFF key (1) of the control unit in ON-Mode, 

the Touch Control may be s witched off at any time. This is also 

applicable for locked control units (active child lock). The ON/

OFF key takes always priority with the POWER-OFF function.

Automatic Switch Off

The TC switches from Power ON to OFF after 20 sec., provided 

that no cooking  zone is activated or a select key is pressed 

during that time.

In case of a selected cooking  zone (with cooking stage is “0“) 

this Auto Power off time is composed of a 10 sec deselection 

time and 10 sec Po wer off time.

ON/OFF Cooking Zone

In case of On-state of the TC a cooking zone may be selected 

by touching   the  dedicated  display  (Select-Sensors  (8)).  The 

respective  display  changes  to  a  steady  display  dot  and “0“ 

instead of “H“ – in case of a  hot cooking zone-. On all other 

cooking zone displays the dot expires.

That followed a cooking  level may be set by using the Slider 

area. Thus switches the respective cooking  zone on. End stops 

are “9“ (right side) and “0“ (left side).

First place the pan in the chosen cooking zone. If the pan is not 

present, the system  cannot be switched on the correspondent 

zone and the display shows the following symbol:

Switching Off a single cooking zone:

A  single cooking  zone may be switched off by selecting and 

setting cooking level to “0”. In case of an optic warning for hot 

cooking zones “H” this is displayed in alternation with “ 0” and 

the synchronously display dot.

After  the  TC is  switched  Off  the  display remains  black 

respectively “ H” is displayed for an optic warning for hot 

cooking zone.

Switching Off all cooking zones:

Immediately switching off all cooking zones is always possible 

by using  the  ON/OFF  key. ”H”  possibly  appears  on  all hot 

cooking zones . All other cooking zone displays remain black.

Power Stages

The power of the cooking zone is adjustable in 9 different stages; 

the respective stage is displayed (“1” to “9”) via LED-seven- 

segment-displays.

Booster Function

The Booster function can be selected by pressing the far right of 

the sliding control (2). With this function, all the cooking zones 

are able to receive a power supply above the nominal power (the 

number of zones with booster at the same time will depend on 

the power provided to the different zones, which must always be 

less than the maximum power of the hob).

The booster activation time is limited to 5 minutes to protect

cooking utensils. After the booster has automatically switched

off, the cooking zone continues to operate at setting level “9”.

The booster can be reactivated after a few minutes.

If the pan is removed from the cooking zone during boosting, the 

booster function remains active and the disabling time continues 

its countdown.

Power management is based on the principle that the last

modification to the setting level in the different zones has top

priority. This means that the setting levels previously configured

in the other zones may be automatically decreased

- If the induction detects that any of the cooking zones requires a

reduction, the display for this zone flashes for 3 seconds to time

for correction prior to modification.

- If the selected zone is re-adjusted within the correction period,

power management analyses the power distribution again. If a

reduction in power is not required the flashing stops and the

original setting level remains on the corresponding display.

- Should power distribution be changed again by the user, the

setting level will under no circumstances automatically increase

in the zones where it has been automatically reduced.

Residual heat indicator

This informs the user that the glass is at a dangerous temperature 

should the area around the cooking zone be touched. The 

temperature is determined by a mathematical model and any 

residual heat is indicated by an “H” on the corresponding 

7-segment display.

Heating and cooling are calculated based on:

· The selected setting level (between “0“ and “9“)

· The ON/OFF time.

After switching off the cooking zone, the corresponding display 

will

indicate “H” until the temperature in the zone has dropped below 

the critical level

(

≤

 60ºC) according to the mathematical model.

Automatic Switch-off (Operating Time Limitation)

For each activated cooking  zone a max.  operating   time  is 

defined. The max. operating time is depending on the selected 

cooking stage. After the expiration of the max. operating time the 

cooking zone is automatically switched off.

Each actuation of the cooking  zone status (changing the cooking 

level etc.) resets the count-down  timer  to  the initial  starting 

value.

Timer settings takes priority vs. operating time limitations for 

high

cooking s tage setting.

Protection against uninte ntional activation

The electronic system  cuts  of f  automatically in  case of  an 

identified  permanent  use of keys  for about 10 seconds.  The 

control  unit  releases  an  audible  signal  for  10 sec  of  the 

malfunction  (period: 1000 msec, 500 msec ON) and  the error 

code “E R 0 3” flashes on the display (0.5 s ON 0.5s OFF). If the 

permanant actuation exceeds 10sec, alone the error code “ER 03“ 

keeps  flashing as long as the malfunction occurs and is identified
