Make the most of your Truma air conditioning system with these few simple tips!
1) Vent your recreational vehicle before switching on the air conditioning system to guarantee fast cooling.
2) Close all windows and doors during operation.
3) Park your vehicle in the shade if possible.
4) Additional insulation, e.g. windows films or protective films prevent the vehicle from heating up.
5) If possible, cover any skylights and windows from outside, as these only cause the temperature inside the vehicle to increase.
6) Clean your roof regularly, because a clean roof does not heat up as quickly.
7) Ensure that there is enough air circulation below the vehicle by means of sufficient openings to prevent air build-up, e.g. attachment of skirt boards.
8) Do not select an inside temperature that differs too greatly from the outside temperature as this strains the body. The cleaning and dehumidification of the air generates a pleasant room climate even when the temperature difference is low.
9) Replace the air filter of your Aventa every year. If you have a Saphir, replace the particle filter once a year and clean the fluff filter twice a year or as necessary. Thanks to the closed cooling circuit, the Truma air conditioning systems are practically maintenance-free, e.g. no coolant needs to be refilled or replaced.
The heater is supplied with gas via a special connection (1). This is either ignited via a battery-operated auto ignition kit (2) or mechanically at the push of the button via the Piezo ignitor in the burner (3). Via the Mica window (4) it is possible to check whether the gas has ignited. External air is sucked into the heater via an inlet (5) and heated via the open flame in the burner (3). The hot air flows through the S-shaped heat exchanger (6) and escapes into the atmosphere together with the exhaust combustion gases via the exhaust pipe (7) and the roof cowl (8). Thanks to the thermo-electrical safety pilot and the fact that the system is completely closed, this process is 100% safe. The heat exchanger (6) heats the direct ambient air in the heater casing. It escapes into the living space through the lamellae of the covers and is distributed within the caravan via the fan (14) as required.
The temperature of the heater can be set steplessly and manually via the control panel knob (9), which activates the safety pilot valve (12) via the control panel rod (11). Once the required room temperature has been reached, a thermostat sensor (13) controls the gas supply to the burner and weakens it accordingly. The fan is controlled via a second control knob (10).
The electrical ancillary heater Ultraheat (15) is an ideal extra for all those who want to use additional electrical heating to heat up their vehicle very quickly independently of the gas system. It heats very quickly and uses the fan of the S-heater to distribute the warm air efficiently in the caravan.
To ensure that the Mover® is ready for use at all times, a reliable power supply must be guaranteed, preferably the AGM batteries with round cell technology. If the Truma Mover® PowerSet is used, the operating time can be extended by up to 50%. It is made of high-quality components which are perfectly matched to the Truma Mover (charger, battery OPTIMA® YT S 2.7 (38 Ah), battery cut-out, temperature sensor and cable set). The drive and lighting batteries are also suitable for the Mover®, e.g. gel batteries or AGM-batteries with round cell technology.
Tipp: If the caravan is not used for a longer period of time, you should always disconnect the connection to the battery via the cut-out as otherwise the battery will deep discharge and suffer damage. In the new Mover® XT the main control system switches off automatically after an hour of non-use.
To store your batteries carefully over the winter it makes sense to remove the battery from the vehicle and place it in a dry and cool place. The battery should always be stored when fully charged and should be recharged every two months (24 hours). For more information about handling batteries correctly, please see the section on tips and tricks.
Tipp: The Truma SolarSet 23 protects the battery against deep discharging.
The heater is started on the Truma Combi LCD control panel (1) and the required temperature for the heater and warm water is set. The heater is connected to the vehicle’s gas supply via the gas connection (2). The gas supply to the heater is controlled via the solenoid valve (3). The required combustion air enters the device via the external pipe of the combined combustion air/exhaust gas cowl (4) where it is transported to the gas burner (6) via the combustion air burner (5). The gas burner, which is equipped with two igniter plugs (7) and a flame rectification electrode, ignites the gas-air mix in the combustion chamber (8).
The hot exhaust gases are deflected at the end of the combustion chamber on the baffle plate of the flame tube (9) and flow back between the flame tube of the burner and the inner wall of the heat exchanger. They escape into the atmosphere via the exhaust gas cowl (4).
The circulating air fan (10) sends the air that is to be heated into the inside of the device. This air flows along the ribs of the heat exchanger (11) that, thanks to its large transfer surface, ensures optimum heat transfer. There are also additional electrical heating rods (12) with 1,800 Watt inside the heat exchanger that can be used to either heat the water and/or warm air. Then the warm air is distributed throughout the vehicle via four warm air outlets (13).
The fresh water is kept in the outer stainless steel water tank that has a volume of 10 litres (14). It is heated from here via the transfer of heat from the heat exchanger (11). Thanks to the eccentric shape of the water tank, the warm water is circulated ensuring an optimum mix and better temperature layering. The warm water connection pipe (15) connects the Truma Combi to the warm water pipes in the kitchen and bathroom. Cold water is pumped from the fresh water tank via the cold water connection pipe (16).
The room temperature sensor (17) fitted in the vehicle measures the air temperature in the vehicle. Also, the water temperature is measured using the internal temperature sensor. Before the required heater and water temperature is reached, the device reduces the heating output. Once the set temperature has been reached, the burner shuts down. If the set heater and water temperatures are undercut, the Truma Combi automatically restarts to heat up the air and water (winter mode). In summer mode, the warm water heater can be operated separately from the heater. The HDF thermal sleeve (18) ensures good insulation of the Truma Combi-heater.
The remote control should always be switched off, using the slide switch at the side after operation in order to minimize battery power consumption.
Symbols of remote control Mover® XT
The remote control performs a self-test after switching on. It is important that neither the rotary switch, the slide switch nor a pushbutton is pressed when this occurs, since zero calibration can otherwise not take place. (Switch off the remote control, discard and wait briefly until the self-test is carried out)
If the remote control is not used for longer than 1 minute, the green symbol for switch on in online condition, which flashes four times and comes along with an acoustic sígnal, disappears. To activate the system, switch the remote control off and on again.
Here one more tip in case the system shuts down:
If the systen is not used for longer than an hour a disconnection of the control unit takes place. (Economy measure) The system has to be made electro less to activate it again. (By using the circuit breaker or disconnect the positive pole of the batterie).
