Fan Deck Arrangement Circuit 2
Note: Present if A/C Fan Control (ACFC) = Integral
This setting is the same as above, except for circuit 2. Each
circuit may have different fan arrangements, but both
must use an identical type of low ambient fan control if
applicable.
Example for Fan Configurations
An air cooled condensing unit is selected that properly
matches the capacity of the RTUD unit intended for a
comfort cooling application. Lets assume the condenser
has 5 fixed speed fans per circuit, and no variable speed
fans or two speed fans, since operation below 32F outdoor
air ambient temperature is not required.
The RTUD chiller should come factory configured as an
RTUD chiller, but the fan configurations will generally need
to be set in the field per the condenser selected and
installed with the chiller. UsingTechView PC based service
tool running on a laptop PC or similar, power up the
controls on the chiller and connect to the PC using an
RS232 cable (connection on the bottom of the CH530
Adaptive Control).
A/C Fan Controls (ACFC)
LaunchTechView and press the “Local Connection” button
in the bottom left hand corner. When the connection is
completed – proceed to the configurations view
And then select tab “CH530” and the “A/C Fan Controls”
item in that list, select “Integral Fan Controls” for that
item:view
Then proceed to theTab “Options Setup” and the item Low
Ambient ControlType in that list; select “None” for that
item.Then proceed to the Fan Deck ArrangementTab and
click on the Fan Deck Arrangement Circuit 1 item. By
clicking In the drop down box, you will see a number of
supported fan deck arrangements. In the drop down we
can see that there are two unique arrangements that
support 5 fans total.The first one is designated as “1H13”
and the 2nd is “1112”.
