2 Installation
2.1 Mounting
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 ca-
bles and mains cables.
In order to mount the device to the wall, carry out
the following steps:
ÎUnscrew the cross-head 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 leav-
ing the head protruding.
ÎHang the housing from the upper fastening point
and mark the lower fastening points (centres
150 mm).
ÎInsert lower wall plugs.
ÎFasten the housing to the wall with the lower fas-
tening screw and tighten.
ÎCarry out the electrical wiring in accordance
with the terminal allocation, (see chap. 2.2).
ÎPut the cover on the housing.
ÎAttach with the fastening screw.
Note:
The minimum pump speed must be set to
100 % when non-speed-controlled devices
such as valves are connected.
2.2 Electrical connection
Note:
Connecting the device to the power supply
must always be the last step of the instal-
lation!
The controller is equipped with 5 relays in total to
which loads such as pumps, valves, etc. can be con-
nected:
Relays 1 …4 are semiconductor relays, designed for
pump speed control.
Conductor R1 … R4
Neutral conductor N (common terminal block)
Protective earth conductor ⏚(common terminal
block)
Relay 5 is a potential-free relay:
R5-A = normally open contact
R5-M = centre contact
Relay 5 is a potential-free relay:
Connections to the R5 terminals can be made with
either polarity.
WARNING! ESD damage!
Electrostatic discharge can lead to
damage to electronic components!
ÎTake care to discharge prop-
erly before touching the
inside of the device!To do
so, touch a grounded surface
such as a radiator or tap!

WARNING! Electric shock!
Upon opening the housing, live
parts are exposed!
ÎAlways disconnect the de-
vice from power supply be-
fore opening the housing!
Note:
For more details about the initial commis-
sioning procedure see page 11.
Depending on the product version, mains cables and
sensor cables are already connected to the device. If
that is not the case, please proceed as follows:
The temperature sensors (S1 to S8) have to be
connected to the terminals S1 …S8 and GND (either
polarity).
The S9 terminal is an impulse input for an impulse
owmeter or a ow switch.
An impulse owmeter can be connected to the termi-
nals S9 /V40 and GND (either polarity).
Connect the irradiation sensor to the terminals CS10
and GND with correct polarity.To do so, connect the
cable marked GND to the GND common terminal
block, the cable marked CS to the terminal marked
CS10.
In the menu, the irradiation sensor will be indicated
as CS10.
The connector marked PWM contains the 2 PWM-/
0-10 V control signal outputs for high-efciency
pumps.

S-Bus GND
1 = PWM output 1, control signal
2 = PWM output 1, GND
3 = PWM output 2, GND
4 = PWM output 2, control signal
In the In-/Outputs menu, relays can be allocated to
the PWM outputs.
Connect the digital Grundfos Direct Sensors™ to
the VFD and RPD inputs.
The controller is supplied with power via a mains
cable. The power supply of the device must be
100 … 240V~ (50 … 60 Hz).
The mains connection is at the following terminals:
• Neutral conductor N
• Conductor L
• Protective earth conductor ⏚(common terminal
block)
WARNING! Electric shock!
L' is a fused contact permanently
carrying voltage.
ÎAlways disconnect the de-
vice from power supply be-
fore opening the housing!
2.3 Data communication / Bus
The controller is equipped with an S-Bus or data
transfer with and energy supply to external modules.
The connection is carried out at the two terminals
marked S-Bus and GND (either polarity). One or
more S-Bus modules can be connected via this data
bus, such as:
• OVENTROP CS-BS Datalogger
• Regtronic EM Extension Module

3 Operation and function
3.1 Buttons
The controller is operated via the 7 buttons next to
the display.They have the following functions:
Button ❶- scrolling upwards
Button ❸- scrolling downwards
Button ❷- increasing adjustment values
Button ❹- reducing adjustment values

3.2 Selecting menu points and adjusting
values
During normal operation of the controller, the display
is in the main menu. If no button is pressed for a few
seconds, the display illumination goes out.
Press any key to reactivate the display illumination.
ÎIn order to scroll though a menu or to adjust a
value, press either buttons ❶and ❸or buttons
❷and ❹.
ÎTo open a sub-menu or to con rm a value, press
button ➄.
ÎTo enter the status menu, press button ➅– un-
con rmed adjustments will not be saved.
ÎTo enter the previous menu, press button ➆–
uncon rmed adjustments will not be saved.
If no button has been pressed within a couple of min-
utes, the adjustment is cancelled and the previous val-
ue is retained.
If the symbol »is shown behind a menu item,pressing
button ➄will open a new sub-menu.
If the symbol ➕is shown in front of a menu item,
pressing button ➄will open a new sub-menu. If it is
already opened, a ➖is shown instead of the ➕.

Values and adjustments can be changed in different
ways:
Numeric values can be adjusted by means of a slide
bar. The minimum value is indicated to the left, the
maximum value to the right.The large number above
the slide bar indicates the current adjustment. By
pressing buttons ❷or ❹the upper slide bar can be
moved to the left or to the right.
Only after the adjustment has been con rmed by
pressing button ➄will the number below the slide
bar indicate the new value. The new value will be
saved if it is con rmed by pressing button ➄again.

When 2 values are locked against each other, they will
display a reduced adjustment range depending on the
adjustment of the respective other value.
In this case, the active area of the slide bar is short-
ened, the inactive area is indicated as a dotted line.The
indication of the minimum and maximum values will
adapt to the reduction.

If only one item of several can be selected, they will
be indicated with "radio buttons".When one item has
been selected, the radio button in front of it is  lled.
If more than one item of several can be selected, they
will be indicated with checkboxes.When an item has
been selected, an xappears inside the checkbox.
