If night setback operation is desired, connect a set of
normally open contacts (field provided) to the
appropriate terminals on the terminal board (7TB7), in
the unit’s control panel. Remove the factory installed
jumper at the terminal board when making the final
wiring termination. Refer to the field connection
diagram, numbers 2307-9122 (for 20 to 60 ton units)
and 2307-9144 (for 80 to 120 ton units) for details.
W7100G Discharge Chilled Water Controller
The discharge chilled water controller (6U11) is
shipped from the factory with a combination wire/
resistor type jumper installed across Terminals 6, 7, &
8. The resistive portion of the jumper is across
Terminals 7 & 8, which set the number of operating
stages, of the control. As shipped, a 200 ohm resistive
jumper is installed across Terminals 7 & 8 on the
controller. The 200 ohm resistive jumper is required for
two (2) stage operation on 20 through 30 Ton units. If
the unit is a 20, 25, or 30 Ton unit, locate the bag that is
secured to the controller, and discard it.

40 to 60 Ton Units
For 40 to 60 ton units requiring four (4) stages of
operation, a 402 ohm resistive jumper must be
installed across Terminals 7 & 8 on the controller.
Remove the combination wire/resistor jumper
containing the 200 ohm resistor from Terminals 6, 7, &
8. Locate the bag that is secured to the controller, and
install the 402 ohm combination jumper across
Terminals 6, 7, & 8 on the controller. Refer to the
remote panel illustration for the terminal identification.
N
No
otte
e:: The resistor portion of the combination jumper
must be installed across Terminals 7 & 8 on the
controller.
80 to 120 Ton Units
For 80 to 120 ton units requiring six (6) stages of
operation, a 604 ohm resistive jumper is needed across
Terminals 7 & 8 on the controller. This jumper is
factory installed.
The descriptions of the following input devices are to
acquaint the operator with their function as they
interface with the Honeywell W7100G controller.
N
No
otte
e:: All wiring must comply with local and national
electrical codes (NEC).
Outside Air Thermostat
(5S57 Field Provided)
The setpoint for the outside air thermostat is based
upon the working ambient selected when the unit was
ordered. A Zero (“0”) in the 11th digit of the model
number indicates the system is designed for standard
ambient operation of 40ºF and above. A One (“1”) in
the 11th digit of the model number indicates the
system is designed for low ambient operation of 0ºF
and above. Therefore, select a thermostat with the
appropriate operating range based on the unit
specifications. See field connection diagram for the
specific connection points inside the remote panel.
Constant Volume Control
(Honeywell W973) — 20 - 60 Ton Units Only
The descriptions of the following basic input devices
used with the Honeywell W973 Master Energy
Controller (MEC) are to acquaint the operator with their
function as they interface with the controller. Refer to
field connection diagram, number 2307-9122, for the
specific component connections at the unit’s control
panel.
