Daikin EWAD420T-XSB2 [12/81] Electrical options on request

OPTIONS

12/73

Blue coat (opt. code 153) An epoxy powder is sprayed and electrostatically fixed to the coil. Once the

surface is completely covered by the epoxy material, the coil is sent in to a furnace for the drying and

curing phase. The result is an uniform and durable coating that enhance the resistance to the corrosion.

The treatment is recommended in all application where moderate risk of corrosion exist (eg: urban,

costal, industrial environments) - Opt. incompatibility: 139

Electrical options (on request)

Soft Starter (opt. code 06) Electronic starting device, alternative to WYE – DELTA compressor starter,

adopted to reduce the mechanical stress during compressor start-up - Opt. incompatibility: 05-11-110

Compressor thermal overloads relays (opt. code 11) Safety electronic devices that, added to the

standard protection devices, protect compressor motors against overload and current unbalance - Opt.

incompatibility: 95

Under over voltage control (opt. code 15) 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 (including current limit) (opt. code 16a) Device installed inside the 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, including current limit option. An integrated

RS485 module allows a Modbus communication to an external BMS.

Current limit (opt. code 19) The option, enabled from the unit controller, limits the maximum absorbed

current of the chiller and so indirectly the cooling capacity of the unit.

Speedtrol (opt. code 42) Continuous fan speed regulation on the first fan (VFD driven) of each circuit. It

allows unit operation down to -18ºC - Opt. incompatibility: 99a-142

Evaporator electric heater (opt. code 57) 125W electric heater, controlled by a thermostat (heater is

activated if water temperature is <5°C) and installed in the evaporator.

Evaporator flow switch (opt. code 58) Supplied separately to be wired and installed on the evaporator

water piping (by the customer). The installation of the flow switch is mandatory.

Compressors circuit breakers (opt. code 95) 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 - Opt. incompatibility: 11.
