Operating Mode - Truma Saphir compact Gebrauchsanweisung, Einbauanweisung

Operating the Saphir compact air conditioning unit with the TG 1000 sinus power inverter
The ElektrikSet (Electrical kit – part no. 40090-23100) and
the KlimaSet (Air conditioning kit – part no. 40090-25900)
are required in order to make the electrical connection of the
power inverter (part no. 40090-81000). A connecting diagram
and a description of the connection are provided with the
respective set.
Operating modes of the TG 1000 sinus
power inverter with the
Saphir compact air conditioning unit
The power inverter is controlled by the air condition-
ing electronics after the air conditioning unit has been
switched on. The air conditioning unit checks the status of the
power inverter and the connected electrical supply at short
intervals (D+ of alternator, starter battery/auxiliary battery and
national network).
If the Saphir compact air conditioning unit is operated
with the TG 1000 sinus power inverter, the following
operating statuses are possible:

Operating mode 1

via auxiliary battery with 12 V
(vehicle engine off, alternator D+ is 0 V).
Switch on the Saphir compact air conditioning unit via the
remote handset.
– If the auxiliary battery voltage is higher than 12 V when the
unit is switched on, the Saphir compact air conditioning unit
is started.
Only FAN MODE with fan settings FAN LOW and FAN HIGH can
be used.
– If the auxiliary battery voltage is lower than 12 V, the red
LED on the IR receiver illuminates. The air conditioning unit
does not start up. Reset by switching the air conditioning
unit off.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the auxil-
iary battery has been recharged (above 12 V – no automatic
restart).
– If the voltage of the auxiliary battery drops to less than
10.8 V while the air conditioning unit is being operated, the
air conditioning unit with power inverter is switched off com-
pletely to prevent further battery discharging. No red LED
therefore illuminates on the IR receiver as a fault indicator.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the auxil-
iary battery has been recharged (above 12 V – no automatic
restart).
The air conditioning unit continues to run and the power
inverter switches itself off when the mains voltage is applied
(connection a – for national network input voltage, see
„Operating mode 3").

Operating mode 2
via alternator with 12 V
(vehicle engine running, alternator supplies D+ = 12 V)
The auxiliary battery and the starter battery are switched in
parallel via the isolating relay. The relay is actuated by D+ from
the alternator (or D+ substitute).
Switch on the Saphir compact air conditioning unit via the
remote handset.
– If the auxiliary battery voltage is higher than 12 V when the
unit is switched on, the Saphir compact air conditioning unit
is started.
The full functionality of the air conditioning unit is
available.
– If the air conditioning unit is operating and the engine is
switched off, the previous setting that was selected using
the remote handset is used when the vehicle is started
again. The switchover procedure is controlled by the
D+ signal.
Tip: To protect the batteries and limit the use of the alterna-
tor charge current, switch electrical consumers off if possible
(e.g. switch refrigerator to gas operation).
– When the engine is switched off the air conditioning unit and
the power inverter switch themselves off. The green LED on
the IR receiver flashes briefly.
– If the starter battery voltage drops to less than 11.7 V
or the auxiliary battery voltage drops to less than
10.8 V during operation, the air conditioning unit with
power inverter switches off completely to prevent further
battery discharging. No red LED therefore illuminates on the
IR receiver as a fault indicator.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the aux-
iliary/starter battery has been recharged (above 12 V – no
automatic restart).
The air conditioning unit and the power inverter switch them-
selves off when mains voltage is applied (connection a – for
national network input voltage, see „Operating mode 3"). The
red LED on the IR receiver illuminates. The air conditioning unit
must be switched on again via the remote hand set.
