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.

CMF10

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
