Microtech III unit controller at the CN_LON1 Header (see

Each Daikin water source heat pump can be equipped
with a
L
on
W
orks
communication module. The
controller is microprocessor-based and is designed
to communicate over a
L
on
W
orks
communications
network. The unit controller is factory programmed and
tested with all the logic required to monitor and control
the unit. The wall thermostat sets the unit mode of
operation. The unit controller monitors water and air
temperatures, and can communicate fault conditions to a
L
on
W
orks
communications network.
The MicroTech III unit controller with communication
module includes a unit-mounted return air, discharge air
and leaving water temperature sensor. Wall mounted
temperature sensors include setpoint adjustment and
tenant override. The user has the capability of substituting
the wall sensor with a duct-mounted return air sensor.
Each unit controller orchestrates the following unit
operations:
■
Enable heating and cooling to maintain setpoint
based on a room sensor.
■
Enable fan and compressor operation.
■
Monitor all equipment protection controls.
■
Monitor discharge air temperature.
■
Monitor leaving water temperature.
■
Relay status of all vital unit functions.
■
Support optional control outputs.
MicroTech III heat pumps with a MicroTech III unit
controller are

certified and designed to be
linked with a centralized building automation system
through a
L
on
W
orks
communications network for
centralized scheduling and management of multiple
heat pumps. Wall-mounted room sensors are available
to control the heating and cooling operation of each
MicroTech III Water Source Heat Pump Unit Controller.
Available room sensors include: room sensor with LED
status and tenant override button, room sensor with LED
status, timed-override button, room sensor with LED
status, timed-override button, and setpoint adjustment,
and room sensor with LED status, timed-override button,
setpoint adjustment.
The MicroTech III water source heat pump unit controller
provides control of Daikin water source heat pumps.
The controller enables the mode of operation, monitors
the water and air temperatures, and indicates fault
conditions. Each unit controller is factory programmed,
wired, and tested for effective operation of your Daikin
water source heat pump.
The MicroTech III water source heat pump controller
uses
