Daikin EUWL20KZW [6/21] Specification text

Switching and control device

In addition to the fully automated µ-Chiller digital controller (manufactured by CARREL), the control cabinet manufactured in accordance

with the valid EN directives (CE) contains all the required switching and control components such as:

Main switch, load, auxiliary and control cut-outs, transformers, control fuses, relay and auxiliary relay, sensors and µ-Chiller digital controller.

The electronics have an automatic restart after power failure and provide the following digital inputs and outputs hard-wired to terminals

for incorporating the GLT:

Digital inputs Digital outputs

- Contactor - Collection fault message

- Pump contact - General operating message

- Allocation of the set point and the desired switching hysteresis

- Cold water return controller (cooling mode)

- Allocation of pump lead times / overrun times

- Allocation of service intervals

- Displaying the current operating parameter such as flow and return temperatures

- Recording operating hours (compressor / pump)

- Fault code query

- Password protection

As an option this chiller can be fitted with an interface for integrating it into a Building Management System (BMS), which either supports

the MODbus / J-bus or BACnet protocol.
