2. General description

Page The RMQ rainwater unit is designed for the monitor-
ing and control of rainwater collection and utilisation
123
systems. The unit detects faults in the rainwater col-
123
lection system and makes the necessary adjust-
124
ments to ensure that the system is operating.
124
When insufficient rainwater is available from the col-
124
lecting tank (e.g. underground tank), the RMQ unit
124
switches to mains water supply, thus providing suffi-
124 cient water at the points of consumption, e.g. water
124 closet, tap. The connection between the integral
125 mains water tank and the suction pipe from the col-
125 lecting tank is closed by means of the built-in three-
way-valve.
126
The RMQ unit has been approved
126
• for the control of rainwater collection systems,
127
• as domestic waterworks for the utilisation of rain-
127
water,
127
• for operation in residential and commercial areas
127
as well as for small enterprises.
