with Saphir remote control� For CP plus or third-
party control unit, please refer to the operating
instructions of the corresponding control unit�
Before switching on, ensure that the vehicle is sup-
plied with 120 V AC / 60 Hz protected with an 20 A
circuit breaker�
The remote control must always be pointed at the infra-
red receiver in order to perform the individual switching
commands�
Before switching on for the first time, the remote con-
trol must be paired with the IR receiver�
Insert batteries (pay attention to polarity)

Operation
6.1
Cooling mode
The air conditioning system ensures cool air inside the
vehicle when operated in cooling mode� The circulated
air fan continues to run in order to provide ventilation�
The air is dehumidified during cooling� If the air
humidity in the vehicle is extremely high at the be-
ginning of the cooling procedure, moisture can build
up on the outside of the air ducts� The doors and
windows should therefore be kept closed and the
highest fan level selected�
6.2
Heating mode (reverse cycle mode)
Heating mode is used when a room temperature above
outside temperature is desired� Saphir heats up the
room air using reverse cycle mode� The circulated air
fan continues to run in order to provide ventilation� If
the room temperature drops below the temperature
setting, the compressor will automatically start�
Heating at an outside temperature of less than
39 °F (4 °C) is not recommended because heating
performance falls considerably� Between 39 °F (4 °C)
and 45 °F (7 °C), the device operates at the "low"
fan level and switches briefly to defrosting processes
(for several minutes)� At above 45 °F (7 °C), there are
no restrictions on heating mode� As soon as 54 °F
(12 °C) is reached, the air conditioning system auto-
matically switches to the fan setting selected on the
remote control�
In order to achieve interior heating that is as effec-
tive as possible at low temperatures, the air condi-
tioning system operates at the "low" level at room
temperatures of less than 54 °F (12 °C)� As soon as
54 °F (12 °C) is reached, the air conditioning system
automatically switches to the fan setting selected on
the remote control�
6.3
Circulated air mode
Circulated air mode only circulates the indoor air with-
out heating or cooling it�
6.4
Automatic mode
The automatic mode automatically controls the room
temperature by automatically switching between cool-
ing and heating mode� Automatic mode is used when
the room temperature can be above or below outside
temperature during operation�
6.5
ACC mode
The ACC mode automatically controls the room tem-
perature together with the Truma Saphir air condi-
tioning system and a Truma Combi / Truma VarioHeat
heater� It is referred to as AUTO mode in the CP plus
menu� In AUTO mode, the air conditioning system will
not be operated in reverse cycle mode (heating)�
