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.

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.

CHARACTERISTIC HEATING CURVE, GENERAL INFORMATION

Generally, an outdoor sensor based controller is always based on the characteristic heating curve.
The curve describes the flow temperature to the heat circuit at a specific outdoor temperature. When
it´s gets colder outdoors, the flow temperature to the heat circuit gets warmer. The characteristic
heating curve has normally a different set-up of slopes. A steeper slope will have a higher flow
temperature compare to flatter slope at the same outdoor temperature.

Example with the graph below: At the outdoor temperature of -10ºC the curve 1.8 will supply
about 74ºC fluid to the heat circuit. On the other hand, the curve 0,6 will only supply about 38ºC
fluid to the heat circuit at the same outdoor temperature.

A characteristic heating curve normally also have the possibility to change the step of the slope at
one point (split point). The curve can be steeper before the point and more flat after the point or vice
versa. Normally there is also a lower and upper limit of the flow temperature.

Example with the graph below: The grey line shows the chosen curve. The lower limit is set to
25ºC, the upper limit to 50ºC. There is a split point at 0ºC outdoor temperature and the first part of
the curve is according to 0,9 settings and the second part of the curve is according to 0,7 settings.

If the user feels that the indoor temperature is too high or low he must change the curve settings and
in some cases also the split point. A change of the curve setting will affect the complete curve. The
CRC110 is made different and a change of the flow temperature will only affect a part of the curve
and the user doesn´t need to think about curve settings or split points. On the following pages the
settings of the CRC110 will be presented and also how the different settings affect the curve.

MENU

The following menu is active if an outdoor sensor is connected to the controller CRC110. If the
outdoor sensor is not connected it will work according to specification for CRA110. If the outdoor
sensor is disconnected the controller will use the last measured outdoor temperature for the following
10 minutes and after that change mode to constant temperature controller and work according to
specification for CRA110.

Main menu: Show the actual flow temperature measured by the temperature sensor on the

pipe.

Setup menu 1: Is activated if joystick is pressed shortly to left/right or down. Will show the

target flow temperature at the closest split point. To change the target flow
temperature, move the joystick to left or right and press joystick to confirm.

Setup menu 2: Is activated if joystick is pressed for 5 seconds. This menu consists of settings

for Maximum flow temperature, Minimum flow temperature, Curve, Offset,
Time constant and Outdoor temperature. The first submenu is Maximum flow
temperature and then presented in the same order as described above. The
joystick on the front cover is used to move between submenus and to change
settings in the submenus.

Setup menu 3: This menu is not recommended for general users since changes of these

parameters will affect how the product operates.

Setup menu 1

The menu is activated if joystick is pressed shortly to left/right or down. This will show the target
flow temperature at the closest split point according to outdoor temperature. To change the target
flow temperature, move the joystick to left or right and press joystick to confirm. Compared to other
outdoor sensor based controllers the CRC will only change part of the curve when the target flow
temperature is changed to be able to do a perfect curve for the application and need.
Example: Today it is -12ºC outside and the house owner feels it is a little too cold in the house and
would like to raise the temperature. He/she goes to the controller and raises the flow temperature by
4ºC. How will that affect the curve?
The curve is divided into 10 parts with 10 split points. When someone changes the flow temperature
in this menu level only the closest split point according to actual outdoor temperature will be
changed. In this example it is the closest split point -10ºC with a flow temperature of 38ºC. The
change of +4ºC will be added to the flow temperature at -10ºC (38+4). The change will also affect
the parts of the curve around the split point until the next split points (-5ºC and -20ºC). Below is an
example of the curve before the change and after the change.

Standard curve (as delivered from factory)

Adjusted curve

The advantage of this function is that the user doesn’t need to know anything about a heating curve
or how to set it, he/she just need to think if it is too cold or hot inside the house. If it is too cold and a
higher flow temperature is needed move the joystick to right and press to confirm, the flow
temperature to the circuit will be higher and the curve is adjusted according to the need.

Maximum Flow Temperature

This setting is used as the upper limit for the characteristic heating curve. The user will not be
able to have a target temperature higher than this upper limit.
Example: The user would like to have a lower limit of the maximum flow temperature
compared to the factory setting of 50ºC. He/she decides to set the upper limit to 45ºC.
How will it affect the curve?

Standard curve (as delivered from factory)

Adjusted curve

When the maximum flow temperature is decreased the curve will be adjusted according to the

adjusted
curve above. If any of the split point has a flow temperature above the new maximum flow
temperature these will be adjusted.
If the maximum flow temperature is increased the curve will not change, but the user will have the
possibility to set a higher flow temperature if needed.

Minimum flow temperature

This setting is used as the lower limit for the characteristic heating curve. The user will not be able
to have a target temperature lower than this lower limit.
Example: The user would like to have a higher limit of the minimum flow temperature compared to
the factory setting of 5ºC. He/she decides to set the lower limit to 22ºC. How will it affect the
curve?

Standard curve (as delivered from factory)

Adjusted curve

If the minimum flow temperature is increased the curve will be adjusted according to the adjusted
curve above. If any of the split point has a flow temperature below the new minimum flow
temperature these will be adjusted.
If the minimum flow temperature is decreased the curve will not change, but the user will have the
possibility to set a lower flow temperature if needed.

Curve

This setting is for user that would like to adjust the characteristic heating curve independent of actual
outdoor temperature. The factory curve is set for under floor heating systems to avoid problems with
too high flow temperature. For applications with high temperature radiators, the curve needs to be
adjusted for higher flow temperatures. Due to the limited number of symbols in the display the
outside temperature is translated to a letter.

Offset (T2)

The controller has the possibility to use offset / parallel adjustment of the characteristic heating
curve. In this menu the offset / parallel adjustment is set. The settings range between – 90ºC to
+90ºC.
When the offset setting is negative, -1 to -90ºC, the minimum flow temperature is the lower limit but
other than that the complete characteristic heating curve will be parallel adjusted.
When the offset setting is positive, +1 to +90ºC, the maximum flow temperature is the upper limit
but other than that the complete characteristic heating curve will be parallel adjusted.
When offset is activated the T2 symbol is shown in the display.

NOTE: When offset is activated is there no possibility to change the target temperature in Setup
menu 1, if the target temperature need to be adjusted, the adjustment shall be made in menu Curve or
in the menu Offset.

Example:

The user would like to have a parallel adjustment of -10ºC and the minimum flow temperature is set
to 10ºC. How will it affect the curve?
The complete curve will be changed except the split point A (+30ºC) because the standard target
temperature is 14ºC but 14-10 = 4ºC and that is not allowed since the minimum flow temperature is
10ºC. Split point A will have a target temperature of 10ºC

Activation Offset (T2)

Inside the controller there is a green connector exactly the same as on the CRA110 and CRB100
controllers. By interconnecting the two conductors the controller will change to offset mode and the
parallel offset temperature will be activated. The activation of the T2 mode is handled by external
equipment such as GSM module CRB915.
NOTE: The connection shall be without any voltage or current and with a maximum resistance of
1000Ω.

Time constant
This is a filter function for applications with well-insulated buildings and quick heating systems such
as a radiator circuit. The filter will delay the impact of a change in the outdoor temperature. This is
used to avoid an imbalance between estimated and actual heating demand. The filter is defined by
how long it takes before the actuator ”knows” 63% of the actual outdoor temperature change. When
the filter setting is for example T=2 the controller will know 63% of the change after 2 hours. The
below graph explain how different outdoor temperature changes and different t settings affect the
controller.

Good insulation / heavy building and quick heating (radiators) = higher time constant.
Good insulation / heavy building and slow heating (under floor heating) = lower or no time constant.
Bad insulation / light building and quick heating (radiators) = lower or no time constant.

The filter function is from factory turned off = setting 0.
