Options and Accessories
MicroTech Controllers
ThinLine fan coils can
be provided with unit-
mounted MicroTech
controllers and multiple
unit- or room-mounted
sensors.
MicroTech controllers can
only be used with remote
room sensors (described
below) and not with remote
thermostats.
A MicroTech controller is
able to operate in either a stand-alone non-communicating
environment or a communicating environment. To
operate in a communicating environment, a board named
communication module, is installed on the unit controller.
There are two types of communication modules available
with MicroTech controllers: LonWorks and BACnet MSTP.
Unit controller sequences and controls: single- or multi-speed
fans, two-position hydronic cooling and heating valves,
oating three-wire hydronic cooling and heating valves,
electric heat, ventilation dampers or economizers.
Unit controllers and/or I-O expansion boards have inputs
for room or return temperatures, temperature setpoint
adjustments, fan speed switches, entering water temperatures,
discharge air temperatures, changeover auto switches, low
temperature detection, emergency shutdown detection,
condensate overow detection, dirty air lter detection
and occupancy. All sensors are software selectable and the
controller is congured based on the selection.
Sensors
Remote-mounted Room Temperature
Sensor with Timed Override
The Basic Sensor provides simple room
temperature sensing all applications.
Unit status is provided through a
ashing LED located on the sensor
while timed tenant override and fault
reset are provided through the Override
button.
Room Temperature Sensor with Setpoint
Adjustable Module and Fan Speed Control
The Digitally Adjustable sensor
provides the ultimate of temperature
control and display, simple user
interface, alarm annunciation,
and alarm reset. The easy to ready
LCD clearly identies the system
operating mode including occupied/
unoccupied mode, fan operation and
control, unit status, timed override
status, alarm annunciation, and
energy savings mode through a
series of recognizable icons. Tactile
response buttons initiate adjustments for temperature set
points, system mode, fan mode, occupancy, tenant override
and fault reset functions. The large numeric LCD will display
space temperature (°F or °C) with the corresponding setpoint
conditions. This sensor is designed for use with BACnet or
LonWorks applications. However, it can also be installed as a
standalone sensor using factory default set points.
Customer-Supplied Controls
Your Daikin Applied representative can work with engineers
and/or contractors to factory install and wire other
manufacturers’ DDC controllers on the fan coil. Contact your
local Daikin Applied sales representative for assistance with
your specific project.
