Cabinet Color Options
Exposed units are shipped in the standard color of Antique
Ivory. Optional colors include: Cupola White, Off White,
Putty Beige and Soft Gray. Custom colors are available as
a special option. Please contact your Daikin Applied sales
represetative. For details of paint colors and nishes, refer to
Daikin McQuay publication Form 2F-1188. Metal samples are
available upon request.
Tamper-proof Cabinet Option
This option can be factory-installed on cabinet units to
prevent access to unit controls and unauthorized removal of
cabinet panels. It includes torx head screws for cabinet panels.
Stamped grille for return and supply air is standard with
tamper-proof models.
Fresh Air Damper Options (Automatic or Manual)
The mixing box module
with top or rear fresh
air inlets is available
for concealed, recessed
or exposed units.
Mixing box control
can be automated or
manual. Automatic
options include a
2-position control or a
full economizer option
(MicroTech controller
only).
Condensate Overow Switch Option
With proper mounting, the
condensate overow switch
will detect water collecting in
the primary drain pan before an
overow can occur. This is a N.C.
low voltage switch that opens
when water levels rise and closes
when water is no longer present.
For units without MicroTech controllers, the switch should be
eld-wired to a controller to facilitate the fan and/or control
valve shut-down when condensate starts collecting in the
drain pan.
Discharge (supply) Air Grille
A stamped-steel supply air grilles are standard for both front
and bottom discharge. Also available is a double deection
grille for front discharge units.
Motor option
Horizontal ThinLine fan coil units are equipped with
standard three-tap Permanently-Split Capacitor (PCS) motors
for 115/1/60, 208-230/1/60 and 277/1/60 volt applications.
Optional brushless DC Electronically Commutated Motors
(ECMs) are available for the above voltage ranges. These
motors are also used for high-static applications. All motors
are connected to a unit-mounted electric panel with Quick-
Connect tting for ease of maintenance.
Electric heater options
Single-point power connection
electric heaters are available for
the following applications: 1) as
total source of heat for the unit; 2)
as supplementary (intermediate)
source of heat between the
seasons. Dual power connections
are available when a motor and a
heater are of different voltage. The heater coils are fabricated
of Nickel-Chromium high-grade resistance wire and are
placed directly in front of the blower outlet. High limit
thermal cut-out protects the heater in the event of insufcient
air delivery.
Total electric heat
Primary coil is used for cooling
only. A single-stage electric
heater provides total heat for the
system. Individual room control
can be provided for manual or
automatic changeover.
Intermediate (supplementary)
electric heat
Primary coil is used for cooling or heating depending on
the season and demand. In summer, while cold water is
circulating in the system the fan coil unit will be cooling the
space. In winter, the circulating hot water will make the fan
coil unit heat the space. Between seasons, when the space
control calls for heating, it will be provided by the electric
heater.
