Operating Status - Truma Saphir compact Instrucciones De Uso

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 re-
quired in order to make the electrical connection of the power
inverter TG 1000 sinus (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 status 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 aux-
iliary/starter battery has been recharged (above 12 V – no
automatic restart).
The air conditioning unit with power inverter switches itself off
if the connection (a) for the national network input voltage is
connected. The red LED on the IR receiver illuminates. The air
conditioning unit must be switched off and on again via the
remote handset.

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 us-
ing 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
switches to standby mode.
– If the auxiliary battery voltage is less than 12 V when the
system is switched on, the red LED on the IR receiver illumi-
nates. 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 starter battery voltage drops to less than 11.7 V
or the auxiliary battery voltage drops to less than 10.8 V dur-
ing operation, the air conditioning unit with power inverter
switches off completely to prevent further battery discharg-
ing. 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 if the input voltage connection (a) for the national
network is plugged in. The red LED on the IR receiver illumi-
nates. The air conditioning unit must be switched off and on
again via the remote handset.
