2 Installation
2.1 Montage
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note
Strong electromagnetic fields can impair the function of the controller.
ÎMake sure the controller as well as the system are not exposed to
strong electromagnetic fields.
The device must only be located in dry interior rooms.
The controller must additionally be supplied from a double pole switch with contact
gap of at least 3 mm.
Please pay attention to separate routing of sensor cables and mains cables.
In order to mount the device to the wall, carry out the following steps:
ÎUnscrew the crosshead screw from the cover and remove it along with the
cover from the housing.
ÎMark the upper fastening point on the wall. Drill and fasten the enclosed wall
plug and screw leaving the head protruding.
ÎHang the housing from the upper fastening point and mark the lower fastening
points (centres 130 mm).
ÎInsert lower wall plugs.
ÎFasten the housing to the wall with the lower fastening screw and tighten.
ÎCarry out the electrical wiring in accordance with the terminal allocation (see
page 5).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.
2.2 Electrical connection
ATTENTION! ESD damage!
Electrostatic discharge can lead to damage to electronic com-
ponents!
ÎTake care to discharge properly before touching the
inside of the device! To do so, touch a grounded sur-
face such as a radiator or tap!
WARNING! Electric shock!
Upon opening the housing, live parts are exposed!
ÎAlways disconnect the device from power supply
before opening the housing!
Note
Connecting the device to the power supply must always be the last step
of the installation!
Note
The pump speed must be set to 100% when auxiliary relays or valves are
connected.
The controller is supplied with power via a mains cable. The power supply of the
device must be 100… 240 V~ (50 … 60 Hz).
The controller is equipped with 2 relays in total to which loads such as pumps,
valves, etc. can be connected:
• Relay 1 is a semiconductor relay, designed for pump speed control:
Conductor R1
Neutral conductor N
Protective conductor
• Relay 2 is a potential-free extra-low voltage relay
Depending on the product version, mains cables and sensor cables are already con-
nected to the device. If that is not the case, please proceed as follows:
Connect the temperature sensors (S1 to S4) to the following terminals with
either polarity:
S1 = Sensor 1 (collector sensor)
S2 = Sensor 2 (store sensor base)
S3 = Sensor 3 (e. g. store sensor top)
S4 = Sensor 4 (e. g. washing machine)
A V40 flowmeter can be connected to the terminals V40 and GND (either po-
larity).
