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.
Information on maintenance and safety
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.
1.1 Safety precautions
The heater may not:
- be operated without containing a minimum quantity (as per the vehicle manufacturer’s specification) of brand-name antifreeze in the water in the heating circuit.
The heater:
- may only be operated with the fuel and the rated voltage specified on the type label.
- must be shut down by switching off immediately and removing the fuse in case of heavy smoking, unusual combustion noises, or combustion odors. The heater must not be restarted before it has been checked by trained personnel in a specialist workshop.
- should be operated for 10 minutes once a month at the lowest fan setting when the engine is cold and the outside temperature is below +20°C.
- must be checked by a specialist every 2 years or at the start of the heating period at the latest.
- must have sufficient fuel to ensure trouble-free operation over the entire operating period.
The fuel in the tank should not reach the “Reserve” level.
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.
Operation
WARNING
The danger of explosion and suffocation
- Do not operate the heater at filling stations and tank installations.
- Do not operate the heater at locations where highly flammable gases or dust can form, or at locations where highly flammable liquids or solid materials are stored (e.g. near fuel, coal and wood dust, grain storage areas, dry grass and leaves, cardboard boxes, paper, etc.).
- Do not operate the heater in closed rooms (e.g. garages), not even with a timer or Telstar.
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.
Pre settings in the vehicle
It may be necessary to preset the system in accordance with the operating instructions for the customer.
Switching on with compatible control elements
The following Webasto Thermo & Comfort SE control elements may be used:
- ThermoCall / ThermoConnect
- Telstar T100 HTM
- Telstar T91 / T99
- MultiControl
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.
Measures in case of malfunction
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.
