Auxiliary heater with parking heater functionality
Dear Webasto Customer,
We assume that the operation and function of your new heater have been explained to you by the installing workshop/service point to your complete satisfaction.
With these operating instructions, we once again wish to outline the safe use of the upgraded auxiliary heater with the parking heater function.
The type approvals in accordance with the regulations ECE-R 122 (heating) and ECE-R 10 (EMC) for the Thermo Top Evo water heater apply in the area where the European Directive 70/156/EEC and/or EC/2007/46 (for new vehicle types as from 29/04/2009) is valid.

1.2 Liability
Failure to observe the operating instructions and the information contained in them will result in a disclaimer of liability by Webasto.
The same applies if repairs are carried out incorrectly or with the use of parts other than genuine spare parts.
This will result in the invalidation of the type approval for the heater and therefore of its homologation / EC type license.
Webasto shall accept no responsibility for the use of components and control elements that have not been approved by Webasto.
We reserve the right to reject warranty claims in the case of malfunctions resulting from disregard of our recommendations.
WARNING
The danger of explosion and suffocation
Depending on the type, the heater may be placed into operation with the control element.

We recommend matching the heating time with the driving time. Heating time = driving time Example: With a driving time of about 20 minutes (one way) we recommend that the heater ON time does not exceed 20 minutes. |
The ventilation function depends on the type of heater.
It may be necessary to preset the system in accordance with the operating instructions for the customer.
The following Webasto Thermo & Comfort SE control elements may be used:
The control elements are compatible with each other. How to use the control elements is described in the respective operating instructions.
Webasto recommends the installation of the operation indicator LED (order number:1320992_) if only Telestart control elements are used.
Fault codes are shown on the MultiControl display or with the ThermoCall / ThermoConnect status check. Refer to the accompanying documentation for the respective control element.
If a malfunction occurs, first check the condition and fit of the fuses and connectors.
You can rectify the following faults yourself:
Fault description | Possible cause | Corrective measures |
The heater switches off automatically (= fault switch-off). | No combustion after start and restart; flame goes out during operation. | Switch the heater off and on again (no more than 2x). |
The heater will not switch on. | No power was applied to the heater. | Check the power supply to heater and ground terminal points. |
The heater switches off during heating operation (=fault switch-off). | The heater overheated due to insufficient coolant. | Top up coolant according to manufacturer’s speck fications. |
You can cancel a fault lock-out yourself as described on the next page.
The fault lock-out is canceled using the fuse in the upgrade. Refer to the customer operating instructions for the position of the fuse.
