CRC110
The CRC110 is a weather compensating controller with integrated actuator with quick and simple
installation on mixing valves. Settings are done by an easy-to-use joystick and display interface on
the front cover.
CRC110 will be used to control the indoor climate based on the outdoor temperature and the
characteristic heating curve. The demand for heat is different due to differences in the type of
building / level of insulation / type of heating / the outdoor temperature and because of this the
curve might need to be adjusted. Normally when the curve is adjusted the complete curve is
changed and a curve that works perfect when the outdoor temperature is -15ºC might not be the
perfect curve when the outdoor temperature is +5ºC. This problem is taken care of in the new
CRC110 there the adjustment of the curve is only made on the part of the curve that reflects the
specific outside temperature. The new controller also has the possibility to use a time constant for
applications where changes of the outside temperature takes several hours before affecting the
indoor temperature but changes of heating supply affect the indoor climate more quickly. There is
also a possibility to use offset / parallel adjustment on the curve for example for night settings.

Enclosure rating: IP41
Protection class: II
Power supply: 230+/- 10% VAC, 50/60 Hz
Power consumption 230V: 10VA
Auxiliary switch: Adjustable 0-90º
Rating Auxiliary switch:* 6(3)A 250 VAC
Weight: 0,4 kg
Running time: ** 30 seconds
Working direction: CW / CCW
Communication*** Communication between actuator unit and
outdoor sensor by ESBus protocol
Approval/certificate: LVD2006/95/EC
EMC 2004/108/EC
RoHS 2011/65/EC
*Auxiliary switch is an option and will be solved by ordinary Auxiliary switch kit 1620 0700.
** Running time of a controller is not so relevant since the total running time from fully open to
fully closed is based on the deviation between set and actual flow temperature.
*** If outdoor sensor is disconnected will the controller change mode to a constant temperature
regulator (CRA111) after 10 minutes. The set temperature in constant temperature mode will be
the last calculated flow temperature during outdoor sensor mode.

ASSEMBLY OF ACTUATOR ON VALVE:
At delivery the controller is placed in mid-position (50% open). Before assembling the controller on
the valve make sure that the valve is turned into mid-position.
1) Remove the knob and scale from the valve.
2) Assemble the actuator on the valve and secure with the screw.
3) The actuator can be assembled in any direction but not under the valve.

SELECTION INFO
The CRC110 controller is the simple version of an outdoor sensor based controller in the ESBE
assortment of controllers. The CRC110 is recommended for the following applications:
There are advantages and disadvantage of both indoor sensor based and outdoor sensor based
controllers.
The main advantage of the outdoor sensor is that the controller “knows” when the outside
temperature change and can directly start to compensate for it. The disadvantage is that the controller
doesn´t know anything about the indoor temperature that can change a lot even if the outdoor
temperature stays the same. For example if it´s windy, the sun is shining, using a stove inside the
house, you have a party with a lot of people or cooking.
The advantage of the indoor sensor based controller is that the controller always knows the actual
indoor temperature and can compensate for that. The disadvantage is if the outdoor temperature
change quickly and the indoor controller has no possibility to compensate in advance and by that it
can be too hot / too cold inside the house for a period of time. There is also a disadvantage of using
only indoor sensor based controllers in heavy building or heavy heating system because there is a
risk that the controller over-react because the reaction time of changes are slow.
