Facts
The mKomfy Cooker Guard is a safety product for use in private homes that
has been developed to prevent fires when cooking.
These instructions apply to Hybrid sensors from SN: 2044 -010000
The mKomfy Hybrid is a Class B cooker guard and does not react to flames
or smoke. It relies on a clear view from the sensor to the hob in order to
detect heat.
The cooker guard will therefore be unable to prevent a fire if the hob is
covered with flammable materials (e.g. cardboard, newspaper), or if such
materials catch fire near the hob.
In order to avoid false alarms, the cooker guard spends a short amount of
time analysing the information from the hob. Hobs powerful enough to
start a fire in under 120 seconds work so quickly that the cooker guard may
find it hard to react before a fire is ignited, depending on the cookware and
the substances in it on the hob.
The product assumes normal care in the use of the cooker and associated
cookware. In normal use the cooker should be kept under frequent
observation, even if safety equipment such as mKomfy is installed.
Lots of smoke will be produced before the device is triggered, so optional
extras such as Power Break could help to make the kitchen a safer place.
The product must be installed and maintained correctly as described,
andmay only be fitted by an authorised electrician.

Accessories
Safety functions
Overheating
The cooker guard monitors the temperature of the cooker and sounds the
alarm if it exceeds the upper limit.
The temperature alarm beeps 3 times every 5 seconds for 20 seconds and
a red light comes on in the sensor. Reduce the temperature of the cooker
immediately to prevent it being turned off, or press the control button on
the sensor to approve the higher temperature for a set time.
Anti-tamper function
The cooker guard has an integral safety function which detects if the
sensor is not correctly mounted in the fixing bracket. If the cooker is in
use and the sensor is incorrectly mounted, the security function will be
activated and beep 5 times in 5 seconds before turning the cooker off.
Replace the sensor in the bracket and press the control button to continue
using the cooker.
Optional timer function (see page 12 for activation)
When the cooker guard detects that the cooker has been turned on, it can
start a built-in timer (countdown clock). When the timer reaches zero, the
cooker is turned off. To restart the timer, press the control button on the
sensor once.
Optional extras for the mKomfy Hybrid cover
additional needs and safety. Compatible with
newer wireless accessories labelled “v2”.

Installation – Relay
Installing the relay (may only be carried out by authorised personnel)
1. Connect and fit the relay in the
cooker circuit.
2. The antenna must extend 9 cm
from the cabinet for optimum
signal strength. NB! if it extends
further,the signal will be worse.
It is fine to thread the antenna
through a plastic pipe with
othercables.
NB: The sensor and relay are factory-paired
and ready to install
See page 15 if re-pairing is necessary

Tip:
If the signal strength is weak/poor, the sensor may not beep in
acknowledgement every time. This can be determined by checking the red LED
on the relay, which will light up if coverage is poor. Moving the antenna slightly
may help. To check whether this is working, press the sensor button briefly
several times. The sensor should beep for every press. If the red LED in the relay
does not light up, the signal strength is fine.

See page 15 if re-pairing is necessary
Fitting the sensor
• The sensor must be fitted at least 70 cm above the hob, either in the
hood or on the ceiling.
• Take note of the coverage (page 7) when fitting the sensor at different
heights.
• The mounting hole is suitable for mounting on a standard wall box.
1. Find a suitable location, see drawings on page 8-10.
2. Mount the bracket.
3. Set the DIP switches to the chosen height and angle (page 12).
4. Insert the batteries (2 beeps = OK), or connect an external
powersupply.
5. Put the sensor in the bracket and press the control button on
the sensor once. A short beep confirms that the sensor is in
communication with the socket and working.
6. Make sure that only the green LED on the relay lights up when the
cooker is connected and turned off. If the yellow LED lights up, the
cooker’s standby electricity consumption is higher than the default
setting. In this case the level in the mKomfy can be calibrated to the
cooker’s actual electricity consumption, see page 12.
Power supply
The sensor can be used with batteries (3 x AA, supplied) or an external
power supply.
NB: It is not possible to use batteries and a power supply at the same time.
The batteries must be removed if an external power supply is used.
Skins for the front panel
On our website, you can find dimensioned sketches for making
your own skins, which you can cut to size and position under
the sensor’s front panel.

considerably. Should only be
deactivated if an external power
supply is used.
Calibrating electricity consumption
If the yellow LED on the relay comes on continuously while the hob is
OFF and does not disappear when the control button on the sensor is
pressed, the standby current to the cooker is higher than the cooker guard’s
preprogrammed standby level.
In this case the level can be recalibrated to actual electricity consumption by:
1. Holding the relay’s control button in until the red and green LEDs flash –
then releasing the button within two seconds.
2. The green LED flashes three times to acknowledge the change.
NB: We strongly recommend measuring the hob’s electricity consumption
in standby BEFORE doing this calibration. High electricity consumption
could be caused by a fault in the hob. Incorrect calibration in the case of high
electricity consumption can result in the cooker guard never starting or not
working as intended.
NB! May only be carried out
byanauthorised electrician.

DIP 9: Autoconnect
Fifteen minutes after turning the
cooker off, the cooker guard will
automatically be reset and turn
the power back on. On a cooker
with rotary switches, all the
rings and oven must be turned off before the cooker guard will reset itself
automatically.
If this function is deactivated or to reset the cooker guard manually, press the
control button on the sensor (or external switch panel, optional extra).
There are three different function tests:
1 = On/Off test 2 = Current test
3 = Temp. test
To activate the function test:
1. Remove the SENSOR cover and set DIP switch 0 to ON
2. Put the cover back on temporarily to stop the batteries falling out.
To change between the three function tests, hold the control button on the
sensor in for 5 seconds. The sensor acknowledges with one, two or three
beeps to indicate the test type.
1 beep On/Off test
The sensor acts as an ON/OFF switch.
Pressing the control button switches between turning the power to the
cooker ON/OFF. The light on the sensor comes on when the relay is on
(sending power to the cooker).
2 beeps Current test
Indicates electricity consumption
for the hob.
Following activation turn the hob
on. A few seconds later the LED
on the SENSOR should come on
continuously and the green and
yellow LEDs on the RELAY should
light up.
Now turn the hob off. The LED on
the SENSOR goes out and only the
GREEN LED on the RELAY should
be on.

NB: The sensor and relay are factory paired
and ready to install
Emergency mode
In the event of problems with the cooker guard that cannot be resolved
there and then, you can activate emergency mode, which connects power
to the cooker for 12 hours (can be repeated for a further 12 hours).
NB: All safety functions are deactivated in this period.
To activate emergency mode:
Remove the fuse for the cooker circuit and hold in the button on the relay
in the fuse cabinet while reinserting the fuse.
NB. The relay will beep once every 30 seconds for the first 5 minutes after
activating emergency mode.
The sensor and relay are factory-paired and ready to install. If re-pairing
isnecessary:
Remove at least once battery from the sensor (you can get batteries ready
for the sensor, but DO NOT fit them).
1. Give the relay control button a quick press. Yellow LED flashes.
2. Hold the control button on the sensor in and fit batteries
inthesensor.
3. There are 2+2 beeps, the blue LED on the relay flashes and the
relay turns off.
