3. HEATER CONTROLLER MOUNTING AND WIRING
Please follow these instructions explicitly as improper installation can result in
permanent damage to your device and/or aircraft.
The Dynon Avionics Heated AOA/Pitot Probe operates on 12V only. For aircraft
with a 24V electrical system, a 24V-to-12V DC-DC converter, capable of supplying
10A, must be used to supply the required 12V at 10A.
The associated power wires and the controller for the Heated AOA/Pitot Probe will
be a source of significant magnetic fields and thus can affect:

Magnetic compass – ensure that there is reasonable separation of the wiring
and the controller from a Dynon Avionics EDC-D10A remote magnetometer or SV-
ADAHRS-200/201, or any other compass-type device that senses magnetic fields.

Audio devices – ensure that there is reasonable separation of the wiring and the
controller from wiring associated with audio systems, especially microphone
circuits and intercoms.
Test for potential magnetic interference by turning on the Heated AOA/Pitot and
check for compass deviation and interference to all audio systems.
PITOT HEAT POWER switch or circuit breaker:
When deciding when to turn the Heated AOA/Pitot Probe On or Off, remember
that even when the Probe’s power is On, it will only heat the probe the amount
necessary to maintain temperature.
