CHANGES TO THE UNIT

Changes to the unit can compromise the safety and function of the unit or the
entire system.
- Changes, additions to or conversion of the unit are not permitted without written
permission from the manufacturer
- It is likewise forbidden to install additional components that have not been tested
together with the unit
- If it becomes clear that safe operation of the unit is no longer possible, for example
because of damage to the housing, then turn the controller off immediately
- Any parts of the unit or accessories that are not in perfect condition must be
exchanged immediately
- Use only original spare parts and accessories from the manufacturer
- Markings made on the unit at the factory must not be altered, removed or
made illegible
- Only the settings actually described in these instructions may be made on the controller
- If the plastic cover on the controller is opened the warranty expires unconditionally

WARRANTY AND LIABILITY

The controller has been manufactured and tested with regard to high quality and safety
requirements. The unit is subject to the statutory guarantee period of two years from the
date of sale.
The warranty and liability shall not include, however, any injury to persons or material
damage that is attributable to one or more of the following causes:
- Failure to observe these installation and operating instructions
- Improper installation, commissioning, maintenance and operation
- Improperly executed repairs
- Unauthorised structural changes to the unit
- Installation of additional components that have not been tested together with the unit
- Any damage resulting from continued use of the unit despite an obvious defect
- Failure to use original spare parts and accessories
- Use of the device for other than its intended purpose
- Operation above or below the limit values listed in the specifi cations
FITTING THE ACTUATOR CONTROL
The adaptor kits needed for ESBE mixing valves are
ADAPTER K IT VRG900
ADAPTER K IT VRG801
supplied with the controller. Connect up the actuator
controller and mixing valve as set out in the brief
description provided with each adaptor kit.
The controller can also be used for other makes of mixing valve using various
adaptor kits that can be ordered. Installation instructions will be enclosed with the
adaptor kit.

INSTALLATION OF TEMPERATURE SENSORS

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 CRS231:
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.
