Daikin EWAQ320E-XL [6/34] Options

OPTIONS

Compressor thermal overload relays - Safety electronic devices

that, added to the standard protection devices, protect

compressor motors against overload and current unbalance.

Phase monitor - Device that monitors input voltage and stops the chiller in case of phase loss or wrong phase sequence.

Under / Over voltage control - Electronic device that monitors and displays input voltage, and stops the chiller in case of phase

loss, wrong phase sequence, or voltage exceeding minimum and maximum allowed values.

Energy meter - Device installed inside th

e control box that displays all chiller electrical power parameters at line input such as line

voltage and phase current,

input active and reactive power, active and reactive energy. An integrated RS485 module allows a

Modbus communication to an external BMS.

Capacitors for power factor correction - Devices that increase the power factor of the unit. The capacitors are “dry”

self-regenerating type with over pressure disconnecting safety device insulated with a no toxic dielectric mix without PCB or PCT.

Speedtrol (fan speed control device - ON/OFF - up to -18°C) - Continuous fan speed regulation on the first fan (VFD driven) of

each circuit. It allows unit operation down to -18ºC.

Setpoint reset, Demand limit and Alarm from external device - Setpoint Reset: The leaving water temperature set-point can

be overwritten with an external 4-20mA, through the ambient temperature, or through the evaporator water temperature ΔT.

Demand Limit: Chiller capacity can be limited through an external 4-20mA signal or via

network. Alarm from external device: The

unit controller is able to receive an external alarm signal. The user can decide whether this alarm signal will stop the unit or not.

Compressors circuit breakers Safety devices that include in a single device all safety functions otherwise provided by standard

fuses and optional thermal relays, such as protection against overcurrent, overload, current unbalance.

Fans circuit breakers - Safety devices that, added to the standard protection devices, protect fan motors against overload and

overcurrent.

Fans speed regulation (+ fan silent mode) - Continuous fan speed regulation of all fans (VFD driven) for improved sound level of

the unit during l

ow ambient temperature operation. At very low temperatures, all fans except the first are switched off thus allowing

unit operation down to -18°C.

INSTALLATION

Rubber anti vibration mounts - Supplied separately, these are positioned under the base of the

unit during installation. Ideal to

reduce the vibrations when the unit is floor mounted.

Spring anti vibration mounts - Supplied separately, these are positioned under the base of the unit during installation. Ideal for

dampening vibrations for installation on roofs and metallic structures.
