Installation of the relay
Relay is sold separately
The relay is necessary to connect the FLOW pre-heater to the interior fan of the vehicle.
When the coolant set temperature
(see operation manual of the control panel)
is reached,
the relay activates the interior fan of the vehicle.
In some cases, the switch of the interior fan of the vehicle must be turned on for
this feature to work.
For vehicles with a climatronic heating system an additional relay may be
needed.
Connect the relay according the connection diagrams (Fig 27 and Fig. 28)
It is important to solder the connections of the wires and to properly insulate the
connection.
