CMF10
Pre-programmed, configurable controller for
simple applications
• Language independent
• Simple configuration via the backlit display
• Input for an external setpoint device
The CMF10 range of controllers can be set to handle
everything from temperature or humidity control to
control of CO2 or pressure. They are intended for DIN-
rail mounting.
• Pre-loaded with several application modes
• 24 V or 230 V AC supply voltage
• Week-based clock / calendar function
CMF
CMF10 is a pre-programmed controller that can be used
for control of temperature, CO2, pressure, and humidity
in air handling and heating applications. It is a stand-alone
controller for simpler applications. CMF is extremely easy
to install, commission and control.
CMF uses a display with an encoder knob, making
its built-in menu system very easy to use. Settings
are entered by turning the encoder knob to a desired
parameter/value. A value is then approved by pressing the
knob.
Models
The CMF series comprises two different types, CMF5U
and CMF10.
CMF5U has 5 in-/outputs and CMF10 has 10 in-/outputs.
CMF10 is available in two versions:
• CMF10 with 24 V AC supply voltage
• CMF10-230 with 230 V AC supply voltage
CMF has been developed according to our Ready-Steady-
Go concept, which simplifies every step from installation to
management.
Applications CMF10 and CMF10-230
CMF10 is pre-programmed with a choice of five different
control modes:
1. Supply air control
2. Supply air control with outdoor compensation
3. Cascaded room / extract air temperature control
4. Radiator circuit control
5. Domestic hot water control
Inputs and outputs
CMF10 has
• 2 analogue inputs, PT1000
• 1 SPI input for an external setpoint device
• 1 universal input, PT1000 or digital
• 2 digital inputs
• 3 digital outputs
• 2 analogue outputs, 0…10 V DC
Internal clock
CMF10 has a built-in week-based real-time clock with a
number of different scheduler alternatives.
Easy to install
CMF is suitable for DIN-rail or cabinet mounting. Since
the terminals are detachable all connections can be made
before CMF is installed.

Display - Base level
This is an example of the display when in Base level view
mode. It is normally shown when there is no operator
activity.
The Base display shows current time and actual value.
There are bar-graphs showing the current output levels
together with symbols showing how the outputs have
been configured (Heating, Cooling or Damper etc).
There is also a symbol showing which of the five control
modes is configured, as well as an alarm symbol that is
displayed in the event of an alarm condition. The fan
symbol (control modes 1, 2 and 3 only) is lit as long as
the fan indication input is activated.
To see the values and status of all in- and outputs, simply
turn the knob counter-clockwise until the text I/O is
displayed and then press it. To return to the Base display,
click on the knob and then turn it clockwise.
Display handling
All setting and configuration is performed using the
display and encoder knob on the front of the controller.
The menu information shown on the display is organised
in a tree fashion. By using the knob you can move in
between menus, set values etc.
In any of the configuration menus, pressing the encoder
knob will activate change mode. You can then turn the
knob to move between choices or set values. A second
press of the knob will accept the choice.
Turn: move up/down in
the menus
Click: enter new menu
or accept new setting
Press for 3 seconds
for time menu,
or 10 seconds for
configuration menu.
The menu system is divided into three levels:
• Base level: view mode
• 3-second level: clock and scheduler settings
• 10-second level: configuration area
Display information
The display can show the following information

CMF10
Configuration
All configuration menus lie in the 10-seconds level. This
level is accessed from the Base Display by pressing and
holding the encoder button for 10 seconds.
There are numerous configuration menus covering all
available options and combinations.
In some cases, making a certain choice in one menu will
mean that you will only see certain other menus. For
example, the menu for setting the damper minimum limit
is only shown if you have configured AO2 to be a damper
control output.

Application examples
CMF10 can be configured to any one of the following control modes.
The three modes on this page have much in common and will therefore be treated in a single section.
Cascade connected room/extract air temperature
control
An offset in room temperature, which if desired can be
set via the external setpoint device, will adjust the supply
air temperature setpoint so as to eliminate the room
temperature offset. One PI and one P control loop are
used. The supply air temperature can be minimum and
maximum limited.
This control mode requires two sensors, “Supply air sensor
” on AI1 and either “Room sensor” or “Extract sensor” on
AI2.
Analogue outputs
The analogue outputs can be configured to the following
combinations (valid for all three examples on this page):
AO1 AO2
1. Heating -
2. Cooling -
3. Heating Cooling
4. Heating Heating
5. Cooling Cooling
6. Heating Dampers
7. Cooling Dampers
3-position control
Instead of the analogue outputs, CMF can be configured
for 3-position control (increase / decrease). Only the
following output choices will then be available:
• Heating
• Cooling
DO1 is used for increase signal and DO2 for decrease.
This option cannot be combined with alarm output.
A single PI control loop is used.
Supply air control
The supply air temperature is kept at the setpoint value
by controlling the output signals on AO1 and AO2. A
single PI control loop is used.
This control mode requires a sensor, “Supply air sensor”,
on AI1.
Supply air control with outdoor compensation
The supply air temperature is kept at the setpoint
value by controlling the output signals on AO1 and
AO2. A single PI control loop is used. The setpoint
is automatically adjusted according to the outdoor
temperature.
This control mode requires two sensors, “Supply air sensor
” on AI1 and “Outdoor sensor” on AI2.

CMF10
Radiator circuit control with outdoor curve
The water temperature setpoint is changed according
to the outdoor temperature. A single PI control loop is
used. A room temperature sensor can be added to give
corrective action if the room temperature differs from the
setpoint.
This control mode requires two sensors, “Supply
temperature” on AI1 and “Outdoor sensor” on AI2.
A room temperature sensor can also be connected to UI1,
permitting the room temperature offset to correct the
supply temperature. Wire UI1 as an analogue input.
3-position control
Instead of the analogue outputs, CMF can be configured
for 3-position control (increase / decrease). DO1 will
then be used for the increase signal and DO2 for the
decrease signal. This option cannot be combined with an
alarm output.
Domestic hot water control
The water temperature is kept constant by controlling the
output signal on AO1. A single PID control loop is used.
This control mode requires a sensor, “Supply water
temperature”, on AI1
