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
