FIGURE 2 - LABEL ON UNIT/VFD FOR MULTI-
SPEED FAN CONTROL
Figure 2 is an example of a label.
C-gen units are 3 or 4 speed depending
on staging.
The multi-speed Fan Control is available on all 8 ton
DSH and DSV units.
For the 15–25 ton DSV units and 10 ton DSH with four
refrigeration stages, the evaporator fan runs at 50%,
60%, 75%, and 100% speed.
For 8–12 ton DSV units and the 8 ton DSH unit with 3
refrigeration stages, the evaporator fan is set to run at
50%, 60%, and 100% speed.
The 2–5 ton DSH units and 5 ton DSV unit do not have
a VFD as a standard and operate at single fixed speed
(100%).

VFD KEYPAD

The VFD requires a keypad to program the VFD. The
keypad is not required to operate the unit when the
VFD is programmed. The keyboard is required dur-
ing initial startup of the unit. Each unit comes with a
factory installed and programmed remote keypad and
short Ethernet clip on connector. An Ethernet commu-
nication cable is supplied by the factory. You can use a
single keypad to program multiple units. Consult with
your sales office to order additional keypads. A copy
of the factory default settings is saved to the keypad
memory available for restore if needed.
