Operating The Saphir Compact Air Conditioning System With The Tg 1000 Sinus Power Inverter; Operating Modes Of The Tg 1000 Sinus Power Inverter With The Saphir Compact Air Conditioning System; Operating Status 1; Operating Status 2 - Truma Saphir compact Operating And Installation Instructions

Operating the Saphir compact air
conditioning system with the TG 1000
sinus power inverter
The electrical kit (part no. 40090-23100) and the air condi-
tioning kit (40090-25900) are needed to make the electrical
connection of the power inverter (part no. 40090-81000).
A connection 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 system
The inverter is controlled by the air conditioning electron-
ics after the air conditioning system has been switched
on. The air conditioning system checks the status of the
power inverter and the connected electrical supply at short
intervals (D+ of dynamo, starter battery / auxiliary battery and
mains).
If the Saphir vario air conditioning system is being
operated with the TG 1000 sinus power inverter, the
following operating statuses are possible:

Operating status 1

Via the auxiliary battery with 12 V
(vehicle engine off, D+ of dynamo is 0 V).
Switch on the Saphir compact air conditioning system via the
remote 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.
Only circulated air fan mode with the low or high fan lev-
els is possible.
– If the auxiliary battery voltage is less than 12 V, the red
LED on the IR receiver illuminates. The air conditioning sys-
tem does not start up. Resetting takes place by switching
the air conditioning system off.
– The air conditioning system with power inverter cannot be
switched on again using the remote control until the auxil-
iary battery has been recharged (above 12 V - no automatic
restart).
– If the voltage of the auxiliary battery falls below 10.8 V
while the air conditioning system is being operated,
the air conditioning system 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 system with power inverter cannot be
switched on again using the remote control until the auxil-
iary battery has been recharged (above 12 V - no automatic
restart).
The air conditioning system continues to operate and the
power inverter switches itself off when mains voltage is ap-
plied (connection a – for mains input voltage, see "Operating
status 3").

Operating status 2

Via the dynamo with 12 V
(vehicle engine running, dynamo 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 dynamo (or D+ substitute).

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.
