Danger!
Live mains connection!
Electric shocks can cause death.
An operating unit or a protection cap must be mounted to the relay modules RM1, RM3 or to the
mains unit NG1 as protection against touching and contact with water.
Caution!
The electromagnetic compatibility of the device is compatible with the emitted interference and
interference immunity for residential and industrial areas. To avoid interfering influences in a
decentralised installation of individual modules, only use data cables from the Lutz company and route
the data cables separate from low-voltage lines.

1. Proper use
For automatic mode (preselected volume), the relay module is required
alongside the basic flow meter and operating unit modules. The relay
module is controlled by the evaluating electronics of the operating unit
and switches the external electrical appliances such as pump motor and
solenoid valve. The electrical connection between the operating unit and
relay module is effected by means of a 10-core ribbon cable.
The relay module RM1/RM3 or the mains unit NG1 includes a power supply
for the operating unit. The batteries only then have a buffer function in the
event of a power failure.
The relay module RM1 and RM3 are fitted with three sockets permitting
the connection of external appliances
