INSTALLATION OF TEMPERATURE SENSORS

The controller operates with Pt1000 temperature sensors which are accurate to the
degree, thus ensuring optimal control of system functions.
If desired the sensor cables can be extended to a maximum of 30m using a
cable with a cross-section of at least 0.38mm². Make sure that there is no
contact resistance!
Position the sensor precisely in the area to be measured! Only use immersion,
pipe-mounted or fl at-mounted sensor suitable for the specific area of applica-
tion with the appropriate permissible temperature range.
The temperature sensor cables must be routed separately from mains voltage
cables, and must not, for example, be routed in the same cable duct!
FLOW PIPE SENSOR CRS211:
The sensor is prewired, and should be secured in a suitable position on the heating
circuit's flow pipe using the pipe clip provided. To make sure that the correct tempera-
ture is registered, the sensor should be surrounded with pipe insulation.
OUTDOOR SENSOR CRS214:
Mount the outdoor sensor in a shady position out of the wind on the north side of the
building.
Connect the cable in the sensor box – polarity does not matter in this case. Depending on
the inertia of the heating system, set the back of the sensor box into the brickwork if neces-
sary in order to take the residual heat of the building into account.
ROOM SENSOR CRS23Z:
If a room sensor is required, it should be connected as follows:
Strip a maximum of 40 mm of insulation from a 4x0.38 mm² cable and insert the end
of the cable through the free lead-in on the underside of the actuator cover. Connect the
cable to the two free terminals in the black cover – polarity does not matter in this case.

INSTALLATION OF CIRCULATION PUMP
Safety information: Power supply must be switched off completely before
work is started on the control and connected loads.
Warning: 230 VAC
If the circulation pump is to be operated via the controller, remove the three safety
terminals from the preconnected cable and connect the cable to the circulation pump
as follows:

Brown:
Please note: If the pump is not connected, the electrician should remove the cable.

POWER SUPPLY - ELECTRICAL CONNECTION

Please note: The controller replaces in no way safety devices. Precautions such as frost,
scald and overpressure protection, etc., must be provided in the installation if necessary.
The controller must only be installed by a qualified electrician in accordance with standards
and/or local regulations.
The 90C controller should be wired up in the following order:
Plug the preconnected cable labelled "power supply" into a 230 V / 50 Hz socket outlet
with earthing contact.

SET-UP

COMMISSIONING HELP / SET-UP WIZARD

The first time the controller is turned on and after the language and time are set, a query
Red
appears as to whether you want to parametrise the controller using the commissioning
help or not. The commissioning help can also be terminated or called up again at any
White
time in the special functions menu 7.2. The commissioning help guides you through the
necessary basic settings in the correct order, and provides brief descriptions of each
Yellow parameter in the display.
Pressing the „esc" key takes you back to the previous value so you can look at the selec-
Blue
ted setting again or adjust it if desired. Pressing the „esc" more than once takes you back
step by step to the selection mode, thus cancelling the commissioning help.
