Operating Status 3; Technical Data; Function Diagram - Truma Saphir compact Gebrauchsanweisung

Switch on Saphir compact air conditioning system via the re-
mote control.
– If the auxiliary battery voltage is higher than 12 V when
the system is switched on, the Saphir compact air condi-
tioning system is started.
The full scope of air conditioning system functionality
is available.
– If the air conditioning system is operating and the vehicle
is then switched off, the air conditioning system restarts
with the setting on the remote control 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 dynamo
charge current, switch electrical consumers off if possible
(e.g. switch refrigerator to gas operation).
– When the engine is switched off, the air conditioning sys-
tem and the power inverter also switch themselves off. The
green LED on the IR receiver flashes briefly.
– If the starter battery voltage falls below 11.7 V or the
auxiliary battery voltage falls below 10.8 V, the air
conditioning system with power inverter switches off com-
pletely to prevent further battery discharging. No red LED
therefore illuminates on the IR receiver as a fault indicator.
The air conditioning system with power inverter cannot be
switched on again using the remote control until the aux-
iliary / starter battery has been recharged (above 12 V - no
automatic restart).
The air conditioning system and the power inverter switch
themselves off when mains voltage is applied (connection a –
for mains input voltage, see "Operating status 3"). The red LED
on the IR receiver illuminates The air conditioning system must
be switched on again via the remote control.

Operating status 3

via mains with 230 V~
The 230 V~ mains is looped through from connector (a) to
connector (c) via a relay in the power inverter. The power in-
verter remains switched off. The air conditioning system can
now be operated with any cooling level.

The air conditioning system with power inverter switches itself
off in the following cases:
– Mains failure
– Mains input voltage connector (a) is disconnected.
The red LED on the IR receiver illuminates The air conditioning
system must be switched on again via the remote control.
If the 230 V~ mains fails, the power inverter is not automati-
cally switched on again in order to prevent unwanted battery
discharging.

– An interior air sensor prevents the compressor from operat-
ing at temperatures of less than +16 °C.
– An anti-freeze sensor prevents non-permitted ice formation
on the evaporator coil.
– A temperature switch prevents excessive current and tem-
perature at the compressor.
