Pre-Installation
Confirm chiller controller system compatibility with AFDH drive
Before starting the process of installing the AFDH, first confirm that the existing chiller controller
system has the hardware and/or software components required to make it compatible with an
AFDH retrofit.
The controller systems that can accept an AFDH retrofit are:
• UCP2™ and UCP2 FastPak™ controller systems shipped after July 1994 (refer to UCP2 sub-
chapter that follows this bulleted list for more details).
Note: If a UCP2 FastPak™ control is equipped with a pulse type actuator, it must first be
upgraded to the current UCP2 style stepper actuator before installing the AFDH retrofit.
• Tracer™ CH531 retrofit control upgrade packages (all models).
Note: The factory installed Tracer™ CH530 chiller controller system will not support an AFDH
Air-Cooled Adaptive Frequency™ drive. The controller system must first be upgraded
to Tracer AdaptiView™ before an AFDH retrofit package can be installed.
• Tracer™ AdaptiView
Note: UC800 controller must be equipped with an AdaptiView software version released in
February 2009 or newer. Upload the correct AdaptiView software version as required.
UCP2 compatibility with AFDH drives
UCP2 chiller controller system history
• Prior to July 1994, UCP2™ and UCP2 FastPak™ controls did not have AFD compatible software
in their Chiller Modules or in their Clear Language Display Modules.
• Between July 1994 to June 1998 the first release of AFD compatible UCP2™ hardware/software
allowed a speed reduction down to as low as 42 Hz.
• In June 1998, the second version UCP2™ software release allowed speed reduction down to 38
Hz, which resulted in slightly improved energy savings.
AFDH compatible UCP2 hardware and software
To determine if a UCP2™ or UCP2 FastPak™ is equipped with hardware and software that will
accept an AFDH retrofit, refer to Table 1 and the instructions below:
1. Open the UCP2 door and record the X-code style part number printed on both the Chiller
Module and the Clear Language Display Module.
a. Compare these X-code numbers to the hardware part numbers listed in Table 1.
i. If the X-codes are equal to or greater than the hardware part numbers listed in Table 1
for each module type, then the modules are both hardware and software compatible with
an AFDH retrofit.
ii. If either (or both) X-codes are lower than the hardware part numbers listed in Table 1, the
module or modules have an unacceptable hardware part number for use with an AFDH
retrofit. Go to Step 2.
2. If the hardware X-code on a Chiller or a Clear Language Display module is unacceptable for use
with an AFDH retrofit, proceed to determine the revision level of the software contained within
each module before condemning it as being totally unusable. To determine the module
software’s AFDH compatibility, go to the UCP2 Clear Language Display and access the Module
Software Revision Levels menu found under the Service Tests group. Record the software
service part numbers displayed for both modules.
a. Compare these software service part numbers to the software part numbers listed in Table 1.
i. If these part numbers are equal to or greater than the software part numbers listed in
Table 1 for each module type, then these modules have previously received a service
