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.
