Daikin EUW10KZW [6/49] 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, .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

The following functions are supported by the electronics, amongst other things:

- Allocation of the set point and the desired switching hysteresis

- Cold water return controller (cooling mode)

- Chilled water return controller (heating 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
