AFDH Startup Procedure
AFDH-SVN03H-EN 43
There has been a tendency with installers to change this
setting to the “North America” setting. The preset
parameters are “Motor Power in KW based.” Changing
[0-03 Regional Settings] to “North America” will change
the drive to “Motor Power in HP based.” This will reset
all of the presets to the default settings. If this
occurs all of the presets must be reprogrammed.
Refer to Table 19 for a list of items that are programmed in
the drive at the factory for use with Trane® chillers. In the
event that the drive needs to be reset, these parameters
need to be reprogrammed into the drive.
To reset the drive to the Danfoss defaults, perform the
following procedure.
1. Disconnect power to the drive, and wait for the display
to shut down.
2. While powering up the drive, press and hold the
following keys: Status, Main, and OK.
3. AFter 5 seconds, release the keys.
After the drive is reset, reprogram
the items listed in
Table 19.
These parameters are supposed to have been set at the
factory to the Trane specific values shown here in Table 19.
Always confirm before actual drive start up that this is so
and correct any one of the parameter settings as
necessary.

(a)There are actually 2 relays under 5 - 40 (Relay 1 and Relay 2). When
entering 5 - 40 the required setting on Relay 1 = Alarm (9) as shown
here but then you need to scroll down to Relay 2 and confirm that Relay
2 = Run (5). The relays are NOT interchangeable. Relay 1 must always
be set to Alarm (9). Relay 2 must always be set to Run (5).
