Danfoss AK2-SC 255

RS.8D.M1.22 AK2-SC 255 Reference Manual 135
The setpoints for the embedded Bitzer alarms are fixed in the compressor electronics
and are only monitored for occurrence by the SC 255. The alarms are virtually self-
explanatory. For further information, consult literature supplied by the compressor
manufacturer.
HVAC alarm
configuration The navigational route to HVAC alarm configuration is as follows: from the Main
Menu, select Configuration, then Alarms, then HVAC. The alarm configuration
menu is shown at left below. When you select HVAC from the alarm configuration
menu, a list menu headed Configure HVAC Alarms will appear. It will list every
HVAC unit that you have configured. Such a list screen appears at right below. For
this very unlikely store we have configured one unit of every type.
The unit types listed are as follows:
AHU Air handling unit. A built-up system.
RTU Rooftop unit. A packaged rooftop unit.
RTC Rooftop controller. Any HVAC system
controlled by a Danfoss (networked or
standalone) RTC board.
