29
4 Operation and function
Description of functions
Switching on
When the heater is switched on, the control lamp in the control element lights up.
The glow plug is switched on and the fan starts at low speed.
Please note!
If there is still too much residual heat in the heat exchanger from when the heater was last used, firstly only the fan starts up (cold blowing).
Once the residual heat has been cleared, the heater starts.
Starting AIRTRONIC
After approx. 60 seconds the fuel supply starts and the fuel/air mixture in the combustion chamber ignites.
Once the combined sensor (flame sensor) has detected the flame, the glow plug is switched off after 60 seconds.
After another 120 seconds, the heater has reached the “POWER” stage (maximum fuel quantity, maximum fan speed).
Starting AIRTRONIC M
After approx. 60 seconds the fuel supply starts and the fuel/air mixture in the combustion chamber ignites.
Once the combined sensor (flame sensor) has detected the flame, the glow plug is switched off after approx. 80 seconds, the heater is in the normal mode.
Temperature selection with the control element
Select the required passenger compartment temperature with the knob. The temperature setting can be between +10 °C and +30 °C depending on the size of the room being heated and the prevailing outside temperature. The required setting of the knob is an empirical value.
Control in the heating mode
During the heating mode, the room temperature or the temperature of the sucked in heating air is constantly measured.
If the temperature is higher than the temperature selected on the control element, the heater starts to regulate its output. There are 4 control stages so that the outflow of heat produced by the heater can be adjusted finely to the heating requirements. Fan speed and fuel quantity correspond to the particular control stage.
If the set temperature is still exceeded in the smallest control stage, the heater goes to the “OFF” stage with the fan running on for approx. 4 minutes to cool off.
Then the fan continues at minimum speed (circulation mode) or is switched off (fresh air mode) until the heater is started again.
Ventilating mode
In the ventilating mode, first the changeover switch “heating/venting” has to be activated and then the heater is switched on.
Switching off
When the heater is switched off, the control lamp goes off and the fuel supply is switched off.
The fan runs on for approx. 4 minutes to cool down.
While the fan is running on, the glow plug is switched on for approx. 40 seconds to clean.
Special case: If no fuel has been supplied or if the heater is in the “OFF” stage until it is switched off, the heater is stopped without any after running.
30
4 Operation and function
Control and safety devices
• If the heater does not ignite within 90 seconds after starting the fuel pump, the start is repeated. If the heater still does not ignite after another 90 seconds of pumping fuel, the heater is switched off, i.e. the fuel supply is off and the fan runs on for approx.
4 minutes.
After an unacceptable number of failed start attempts, the controller is locked.* • If the flame goes off by itself during operation, the heater is restarted. If the heater does not ignite within 90 seconds after the fuel pump has started, or ignites and goes off again within 15 minutes, the heater is switched off, i.e. the fuel supply is off and the fan runs on for approx. 4 minutes.
This status can be remedied by briefly switching off and on again.
Do not repeat the switching off/on routine more than twice.
• In the case of overheating, the combined sensor (flame sensor/overheating sensor) triggers, the fuel supply is interrupted and the heater switched off.
Once the cause of the overheating has been eliminated, the heater can be re-started by switching off and on again. After the heater has been switched off for overheating an unacceptable number of times, the controller is locked.* • If the lower or upper voltage limit is reached, the heater is switched off after 20 seconds.
• The heater does not start up when the glow plug is defect or when the electric lead to the dosing pump is interrupted.
• If the combined sensor (flame sensor / overheating sensor) is defect or the electric lead interrupted, the heater starts up and is then switched off again during the start phase.
• The speed of the fan motor is monitored continuously. If the fan motor does not start up or if the speed deviates by more than 10%, the heater is switched off after 30 sec.
• When the heater is switched off, the glow plug is switched on for 40 seconds (after-glowing) while the fan runs on to clean off any combustion residues.
* The controller can be enabled again and the faults read off: • using the module timer • using the radio remote control TP5.
For other controls: • by connecting up a diagnosis unit • using the customer service program KD2000.
For operation and fault list, please refer to the enclosed operating instructions or the troubleshooting and repair instructions for the heater.
Please note!
Do not switch the heater off and on again more than twice.
Forced shutdown in ADR / ADR99 mode (only for diesel heaters)
In vehicles for the transport of dangerous goods (e.g. tanker trucks), the heater must be switched off before the truck drives into a danger area (refinery, fuel service station, etc.).
Failure to comply results in the heater switching off automatically when: • The vehicle engine is switched off.
• An additional unit is started up (e.g. auxiliary drive for unloading pump etc.).
• A vehicle door is opened (ADR99 regulation, only in France).
The fan then runs on for max. 40 seconds.
Emergency shutdown – EMERGENCY OFF
If an emergency shutdown – EMERGENCY OFF – is necessary during operation, proceed as follows: • Switch the heater off with the control or • pull the fuse out or • disconnect the heater from the battery.

• Switch the heater off once a month for about 10 minutes, even outside the heating period.
• Before the heating period starts, the heater should undergo a trial run.
If persistent extreme smoke develops, unusual burning noises or a clear fuel smell can be perceived or if electric/electronic parts heat up, the heater must be switched off and put out of service by removing the fuse.
In this case, the heater should not be started up again until it has been checked by qualified staff who have been trained on Eberspächer heaters.
• Check the openings of the combustion air supply and exhaust system after longer standstill periods, clean if necessary!
