Daikin EWAT260B-SRB2 [5/62] Features and benefits
FEATURES AND BENEFITS
5/62
accidental contact with live parts. The main panel is fitted with a main switch interlocked door that shuts off
power supply when opening.
MicroTech III controller
Units are equipped with MicroTech III advanced controller that can be used to modify unit set-points and check
control parameters. Regulation type is proportional integral derivative regulation on the evaporator leaving
water temperature.
A built-in display shows chiller operating status, temperatures and pressures of water, refrigerant and air,
programmable values and set-points.
A sophisticated software with predictive logic, selects the most energy efficient combination of compressors,
EEXV and condenser fans to keep stable operating conditions to maximize chiller energy efficiency and
reliability. MicroTech III is able to protect critical components based on external signals (such as motor
temperatures, refrigerant gas and oil pressures, correct phase sequence, pressure switches and evaporator
flow switch).
Control section - main features
Main control features are (for more information refer to Unit Control Manual):
164x44 dots liquid crystal display with white back lighting
Optimized management of compressors.
Display of evaporator entering/leaving water temperatures.
Display of Ambient Temperature
Display of refrigerant condensing/evaporating temperatures and pressures.
Regulation of leaving evaporator water temperature.
Display of compressor working hours and number of compressor starts.
Re-start in case of power failure (automatic or manual depending on failure type).
Soft load (optimized management of the compressor load during the start-up).
Set point reset.
Master/Slave operation (up to 4 chillers connected).
Variable Primary Flow Management (available as option)
Alarms signaling (for more information refer to Unit Control Manual):
Phase loss.
Evaporator water flow loss.
Evaporator water freezing protection.
External alarm.
Low evaporator refrigerant pressure.
High refrigerant pressure (transducer).
High refrigerant pressure (switch).
High refrigerant discharge temperature.
High oil pressure differential.
High motor temperature.
Low ambient temperature lock-out.
Freeze protection.
Supervising systems (on request)
MicroTech III remote communication
MicroTech III is able to communicate to BMS (Building Management System) based on the most common
protocols as:
ModbusRTU (Native)
LonWorks, now also based on the international 8040 Standard Chiller Profile and LonMark Technology.
BacNet BTP certifief over IP and MS/TP (class 4) (Native).
Ethernet TCP/IP (Native).
