Fault Cause Remedy
No radio
reception.
1. Transmitter is not
programmed.
2. No power supply.
1. Program the
transmitter.
2. Switch on power
supply.
Bad radio
reception.
Unfavourable position of
receiver.
Change position of
receiver or aerial.
Heater does
not heat or
only heats
with reduced
power.
1. Radio heater wrongly
connected.
2. Heating element is
defective.
3. Overtemperature war-
ning, overtemperature
shutdown or emergen-
cy shutdown active.
1. Check connection.
2. Replace heating
element.
3. Provide for cooling;
in the case of emer-
gency shutdown
also switch off the
supply voltage.
Troubleshooting
Overtemperature warning
At heat sink temperatures of approx. 90 °C and above, the
Combio-868 HE automatically reduces the heating power to 50 %.
If the ▲ or ▼ button is pressed while the heating power is reduced,
the Combio-868 HE switches to 100 % heating power for
2 seconds, but then drops back to 50 %.
Once the heat sink temperature falls below 80 °C, the
Combio-868 HE can be operated normally again.
Overtemperature shutdown
At a heat sink temperature of approx. 100 °C and above, the radiant
heater is switched off by the Combio-868 HE.
If the ▲ or ▼ button is pressed while the radiant heater is switched
off, the Combio-868 HE switches to 100 % heating power for
2 seconds, but then switches the radiant heater off again.
Once the cooling temperature drops below 90 °C, the
Combio-868 HE switches to the overtemperature warning state.
Emergency shutdown
At a heat sink temperature of approx. 110 °C and above, the radiant
heater is switched off by the thermal switch in the Combio-868 HE.
This thermal switch has a latching function.
The supply voltage must be switched off in order to put the
Combio-868 HE back into operation after cooling.
