OPTIONS

Standard Options (supplied on basic units)

Double set point (opt. code 10 – provided as standard)

Possibility to pre-set two different chilled water temperatures set-points for chilled water.

Compressor thermal overload relays (opt. code 11 – provided as standard) – Opt. incompatibility 95.

Functionality included in the compressor inverter device.

Phase monitor (opt. code 13 – provided as standard)

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

Inverter compressor starter (opt. code 14 – provided as standard)

Electronic device used as starter and for compressor capacity control.

Under over voltage control (opt. code 15 – provided as standard)

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.

Evaporator Victaulic KIT (opt. code 20 – provided as standard)

For unit equipped with plate to plate heat exchanger the victaulic kit (provided as standard) includes the victaulic

joint and the counter pipe fitted with victaulic groove to be welded with the plant pipes - Opt. incompatibility 21.

20mm evaporator insulation (opt. code 29 – provided as standard)

The heat exchanger is covered with a 20mm closed cell insulation material - Opt. incompatibility 08.

Evaporator electric heater (opt. code 57 – provided as standard)

Electronic expansion valve (opt. code 60 – provided as standard)

Discharge line shut-off valve (opt. code 61– provided as standard)

Installed on the discharge port of the compressor to facilitate maintenance operation.

Suction line shut-off valve (opt. code 62– provided as standard)

Installed on the suction port of the compressor to facilitate maintenance operation.

Set point reset, demand limit and alarm from external device (opt. code 67/90 – provided as

standard) 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.

Hour run meter (opt. code 68 – provided as standard)

General fault contactor (opt. code 69 – provided as standard)

Fans circuit breakers (opt. code 96- provided as standard)

Safety devices that, added to the standard protection devices, protect fan motors against overload and

overcurrent.

Main switch interlock door (opt. code 97 – provided as standard)

Master / Slave (opt. code 128 – provided as standard)

The EWAH~TZ B features the DAIKIN Master/ Slave (M/S) control. Once set which unit has the role of master,

the other(s) will operate as slave(s) based on the inputs provided by the master.

The chillers must be installed in parallel in the hydronic plant.
