DC-Kit2 with Dometic B1600 Plus/B2200, FreshLight1600/2200

 Roof air conditioner:
– Dometic B1600 Plus/B2200
– Dometic FreshLight1600/2200
 Circuit diagram:
– Dometic B1600 Plus/B2200: fig. 5, page 7
– Dometic FreshLight1600/2200: fig. 7, page 9
 Charging current distributor: ECL-102
 Inverter: PerfectPower PP2002
The light system voltage UD+ is measured. If this voltage exceeds a variable voltage
value Ue (12.5 V – 14.0 V), the relay contact 30/87 (Batt. 2/Batt. 2) of the power relay is
closed. The starter battery and the additional battery are therefore connected in parallel
with low resistance and are charged together by the light system.
Contact I5/I2 is opened with UD+ > Ue and this switches the air conditioner on.
If the light system voltage falls below a variable threshold value Ua (10.5 V – 12.5 V), due
to an increased load because of the air conditioner, relay contact 30/87 (Batt. 2/Batt. 2) is
closed. Relay contact I5/I2, which interrupts the connection between the on/off cable and
the air conditioner, is closed.
The air conditioner compressor is switched off in this way. The light system now charges
the starter battery. If the vehicle has a connecting cable between the two batteries, the
additional battery is also charged.
If the charging voltage of the light system UD+ reaches the set voltage value Ue again,
the power relay and the control relay switch on again. The air conditioner compressor
starts again.
If the vehicle engine is not switched on (UD+ = 0 V), relay contact 30/87 (Batt. 2/Batt. 2)
and relay contact I5/I2 are opened. The air conditioner can be operated and only takes
power from the additional battery. If the battery voltage falls below Ubatt = 10.5 V, the
inverter switches off.

DC-Kit2 with Dometic FreshJet1100/1700/2200

 Roof air conditioner: Dometic FreshJet1100/1700/2200
 Circuit diagram: fig. 6, page 8
 Charging current distributor: ECL-102
 Inverter: SinePower MSI1812T
The light system voltage UD+ is measured. If this voltage exceeds a variable voltage
value Ue (12.5 V – 14.0 V), the relay contact 30/87 (Batt. 2/Batt. 2) of the power relay is
closed. The starter battery and the additional battery are therefore connected in parallel
with low resistance and are charged together by the light system.
Contact I2/I5 is opened with UD+ > Ue. This switches on the air conditioner.
