8. AUX Mode and Its Functions
The AUX is a secondary control circuit—essentially, a small power supply that provides a 12VDC (up
to 200 milliamps) output current. It is either active (12VDC on) or inactive (0VDC). Most AUX modes or
functions are designed for specialized applications and are infrequently used.
• To access the AUX MODE from the MAIN Menu, press the <
> soft key until the arrow is in front of
the Aux selection (see next page).
• A 200 milliamps or less, 12VDC/2.4W device can be wired directly to the AUX terminal; higher output
DC loads require a 12VDC coil relay—also rated up to 200 milliamps or less for the DC coil—which
itself is connected to the AUX output. An internal, re-settable Positive Temperature Co-ecient (PTC)
fuse protects the AUX internal components from overcurrent or a short circuit.
• For certain AUX control applications the use of a solid state relay is preferred. This is particularly
benecial with applications such as the Diversion mode where fast switching (often called PWM
control) allows a more constant battery voltage to be maintained. Both DC and AC load
switching solid state relays are widely available from many sources. Eurotherm and Power-IO
are two suggested solid state relay manufacturers.
• Only one AUX MODE can operate at a time (
even if other modes have been preset).
• See Figure 5, page 36, for an AUX set-up wiring diagram example.
In this Menu, On and O
indicators show the present
state of the Aux terminals.
Pressing the <MODE> soft
key changes the outputs
value (On, O, or Auto)
On indicates the Aux Output
is in an active state; O
indicates an inactive state.
The second line indicates the
present mode for the Aux Output.
When this line blinks, it indicates a
pending AUX Mode.
When the preferred mode is
displayed, press the <SET> soft
key to select it.
Pressing the <NEXT> soft key
changes to the next mode.
