Oil heater K 120 (R) / K 160 (R)
Switching the device off.
Attention
Damage to the heat exchanger by pulling
out the mains plug
If the device is switched off by pulling the plug,
the device cannot cool down and this can lead to
damage to the combustion chamber, the flame
monitor and the fan. The safety temperature lim-
iter may switch off and lock under certain circum-
stances. The device will only restart after the
safety temperature limiter has been unlocked.
a) Always switch off the device with the device
switch and wait for the cooling phase (tem-
perature indicator shows ≤ 30 °C) before
disconnecting the device from the mains.
a) Turn the device switch to the position [0].
CAUTION! Do not pull the mains plug as
long as the temperature indicator shows
more than 30 °C and the fan is still run-
ning!
The temperature control switches the fan
off with a time delay.
If the device has been operated in ventila-
tion mode before being switched off, the
fan switches off immediately and the de-
vice can be disconnected from the mains if
necessary.
You have now switched off the device.

Operating modes
The device can release the sucked-in air into the
room without heating (ventilation), or release
heated air while the burner is running (heating).
Heating:
The operating mode is activated by
switching the device switch to position [I]. After
switching on:
– The operating light is green
64 / 85
– The status light "Burner" on the HEYtronic
display lights up
– The status light "Fan" on the HEYtronic dis-
play lights up at a temperature of 40 °C or
higher.
– Starting the oil preheating
– After the preheating time (approx. 45 seconds)
has elapsed, the burner starts
– As soon as the temperature sensor on the
blow-out nozzle measures > 40 °C, the fan
starts
CAUTION! Never disconnect the device from the
mains before it has cooled down sufficiently!
After switching off, the fan continues to run until
the temperature indicator shows ≤ 30 °C.
Ventilate:
The operating mode is activated by
switching the device switch to position [II]. After
switching on:
– The fan switches on and conveys the sucked-
in ambient air
18.3
Operating the external ambient
temperature regulator
A room thermostat is installed at the room
thermostat socket provided for this purpose
on the front of the device.
The device is now ready for operation.
a) Set the room thermostat to the desired target
temperature.
b) Turn the device switch to position [I].
The device starts the heating mode when
the room temperature is lower than the set
temperature.
The device will switch itself off as soon as the
set temperature is reached. The fan continues
to run until the temperature at the blow-out
nozzle is ≤ 30 °C. If the temperature falls be-
low the target temperature again, the device
restarts the heating operation.
