Overview
The Sargent MC100 Control Unit can be interfaced with the Webasto Thermo Top EVO heating system, allowing the heater to be controlled from the Sargent EC970 Control Panel. In order to do this the following additional parts are required, which are available directly from Sargent:-
- Fan Adaptor PCB (Part: 17464)
- Fan PCB harness (Part: 89003-24)
Wiring
The system should be wired as per the attached diagram, which details how to make connections between the Webasto heater and Sargent Control Unit
Note that the cable colours shown are for harnesses provided with the standard Modular System kit (Part: K970A) and may vary for OEM installations

For installation and setup advice for the heating system, please contact Webasto or visit the Webasto portal at the link below
