Nibe F2120-12, Руководство по установке

Страница: 33 / 68

General
F2120 is equipped with an internal electronic controller
that handles all functions necessary for operation of
the heat pump, e. g. defrosting, stop at max/min tem-
perature, connection of the compressor heater, and
protective functions during operation.
Temperatures, number of starts and run time, are read
off in the indoor module/control module.
The integrated control shows information via status-
LEDs and can be used during servicing.
Under normal operating conditions the home owner
does not need to have access to the controller.
F2120 communicates with the NIBE indoor module/con-
trol module, which means that all settings and meas-
urement values from F2120 are adjusted and read off
on the indoor module/control module.
LED status
The base board (AA2) has six status LEDs for easy con-
trol and fault tracing.

Master control
To control F2120, a NIBE indoor module/control mod-
ule is required, which calls upon F2120 according to
demand. All settings for F2120 are made via the indoor
module/control module. It also shows the status and
sensor values from F2120.
