Operating Modes Of The Tg 1000 Sinus Power Inverter With The Saphir Vario Air Conditioning Unit; Operating Mode 1; Operating Mode 2 - Truma Saphir vario Instrucciones De Uso

Operating modes of the TG 1000 sinus
power inverter with the Saphir vario air
conditioning unit
The Electrical Kit (part no. 40090-23100) and the Air condition-
ing Kit (part no. 40090-25900) are required in order to make
the electrical connection of the power inverter TG 1000 sinus
(part no. 40090-81000). A connecting diagram and a descrip-
tion of the connection are provided with the respective set.
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 vario air conditioning unit is operated with
the TG 1000 sinus power inverter, the following operat-
ing statuses are possible:

Operating mode 1

via auxiliary battery with 12 V
(vehicle engine off, alternator D+ is 0 V).
Switch on the Saphir vario 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 vario air conditioning unit
is started.
Regardless of the mode that is selected, the cool-
ing power is limited to the lowest setting in this
mode (COOL LOW), even if a higher cooling mode is
indicated!
Any fan power setting can be selected.
FAN mode (ventilation):
– FAN LOW
– FAN HIGH
– 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 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 auxil-
iary 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.
When the engine is started the Saphir vario switches to the
previously selected cooling mode (COOL LOW or COOL).

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 vario 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 vario air conditioning unit
is started.
Regardless of the mode that is selected and indicated,
the cooling power is limited to the lowest and
medium setting in this mode (COOL LOW or COOL),
even if a higher cooling mode is indicated!
Any fan power setting can be selected.
FAN mode (ventilation):
– FAN LOW
– FAN HIGH
Tip
To protect the batteries and limit the use of the alternator
charge current, switch electrical consumers off if possible
(e.g. switch refrigerator to gas operation).
– The system automatically switches to operating mode 1
when the engine is switched off. If the air conditioning unit
is operating at the medium setting (COOL) and the vehicle
is switched off, the unit automatically switches to the lowest
setting – COOL LOW. When the vehicle is started up again
the unit is automatically switched to the COOL setting again
if this is still selected on the remote handset. The switchover
procedure is controlled by the D+ signal.
– 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 during operation, the air conditioning unit with pow-
er inverter switches off completely to prevent further battery
discharging. No red LED therefore illuminates on the IR re-
ceiver as a fault indicator.
The air conditioning unit with power inverter cannot be
switched on again using the remote handset until the
auxiliary / 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.
