Configuration -> Control -> MISC
The term Miscellaneous refers to the ability to monitor and
control miscellaneous areas of an application using Danfoss AK
I/O (modules). For example, a miscellaneous relay output may be
required for an exhaust fan, a dispenser that adds chemicals, an
oven, a produce fogger, or any other device that can’t or
shouldn’t be treated like an ordinary refrigeration, HVAC, or
lighting asset. Miscellaneous on/off, sensor inputs can be used in
defining the control strategy for miscellaneous relay outputs.
Any miscellaneous points configured can be monitored for
history, and may be configured strictly for that purpose, or for
alarms. Routable alarms can be created for any Miscellaneous
point. For sensor inputs, the AK-SM allows custom conversion for
non-Danfoss sensors that have a linear response (known as
Conversion factors)
The initial Miscellaneous definition is set out in the Configura-
tion->Control page (see below). In addition to Relay, Sensor, On/
Off Inputs and variable outputs the Misc section also has
Conversion Factors & Calculations. Further details on conversion
factors and calculations can be seen in this section.
Once the required misc points have been set (number required),
configuration is done under the
Misc
tab.
Miscellaneous Configuration
Configuration-Control screen
In this example a miscellaneous sensor has been configured, but
the same principle will apply if configuring Relays, On/Off and
variable outputs. Under the Misc tab, navigate to the sensors tab.
Enter a suitable description for the sensor, then under the Bd-Pt
line, enter the board & point address for the sensor in question. In
this example the address 01-1.2 has been assigned. Review the
remaining items in the list and configure according to your site
requirements.

Sensor (01-1.2)
Example of I/O module line up. The communication module (AK
CM 101A) has an address set as 1, with module 1 having the sensor
in location 2. This is then entered in the AK-SM as 01-1.2
for this example the board and point address 01-1.2 is assigned
