1.1 Mounting
The unit must only be located indoors. It is not suitable
for installation in hazardous locations and should not be
sited near to any electromagnetic field. The controller must
additionally be equipped with an all-polar gap of at least 3 mm
or with a gap according to the valid installaton regulations,
e.g. LS-switches or fuses. Please pay attention to a separate
laying of the cable lines and installation of ac power supply.
1. Unscrew the cross-recessed screw of the cover and
remove it from the housing.
2. Mark the upper fastening point on the wall and premount
the enclosed dowel and screw.
3. Hang up the housing at the upper fastening point and mark
the lower fastening point on the underground (hole pitch
130 mm), afterwards put the lower dowel.
4. Fasten the housing at the underground.
1. Installation
Warning!
Switch-off power supply before
opening the housing.
1.2 Electrical wiring
The power supply to the controller must only be made by
an external power supply switch (last step of installation!)
and the line voltage must be 115 Volt (50...60 Hz). Flexible
lines are to be fixed at the housing by enclosed strain relief
supports and screws.
Depending on the version the controller is equipped with
1 relay to which the consumers e.g. pumps, valves etc. can
be connected:
• Relay 1
18 = conductor R1
17 = neutral conductor N
13 = ground clamp
The temperature sensors (S1 up to S4) will be connected
to the following terminals independently of the polarity:
1 / 2 = Sensor 1 (e.g. Sensor collector 1)
3 / 4 = Sensor 2 (e.g. Sensor tank 1)
5 / 6 = Sensor 3 (e.g. Sensor TSPU)
7 / 8 = Sensor 4 (e.g. Sensor TRF)
The power supply is effected to the clamps:
19 = neutral conductor N
20 = conductor L
12 = ground clamp
net clamps
fuse
consumer clamps
Sensor clamps
hanging
fixation
earthing clamps
Electrostatic discharge can lead to damages of elec-
tronic components!
Dangerous voltage on contact!
