Description of the device
4.1
Description
The device is a makeup station for heating or cooling water systems with a pump
and a system separator vessel. The device controller controls the freshwater
makeup for the plant system.
You can select from two makeup variants for this device:
•
Freshwater makeup for plant systems with a diaphragm expansion tank.
•
Freshwater makeup for plant systems with a pressurisation station.

The device controller uses the pump to regulate the make-up with fresh water
for the system circuit.
The controller monitors the following parameters:
•
Make-up time
•
Make-up cycles
•
Make-up quantity, if an optional contact water meter is installed
The controller will detect small leaks in the system. When a leak is detected, the
controller interrupts the make-up with as soon as the make-up time or the make-
up cycles are exceeded. An integrated insufficient water protection sensor
deactivates the pump to prevent it from running dry.
You can select from two make-up variants for this device. These variants depend
on the system circuit.
•
Water make-up to system circuits with a diaphragm expansion vessel.
–
The pressure transducer sends a signal to the controller if the
pressure drops below the minimum working pressure of the system
circuit. The controller activates the pump. The system circuit is
replenished with fresh make-up water from the mains separator
tank. For calculating the filling pressure in the system circuit, see
chapter 7.2 "Determining the P
minimum operating pressure for the
•
Water make-up using a pressurisation unit.
–
Pressurisation units are equipped with filling level monitors. When
the filling level falls below the minimum level, the pressurisation unit
sends a signal to the device controller. The controller activates the
pump. The system circuit is replenished with fresh make-up water
from the mains separator tank.
Note!
The make-up variant is set in the Customer menu, see chapter 9.2.1
"Customer menu" on page 12 .
