1.Manual Introduction

The 1500-3000W is an air-cooled water chiller that continuously provides cooling water through a compressor refrigeration system, stably supporting full-power long-term laser operation. This product features a compact size, high temperature control accuracy, and simple operation. It can be used to cool heat-generating equipment such as lasers, servers, and motors.

2.Scope of Application

This specification applies to the handheld integrated water chiller units for laser applications, models 1500W, 2000W, and 3000W.

  6.Panel Description

• Display/Control	Purpose
  Digital Display Window	Displays low‑water measured temperature, low‑water set temperature, high‑water measured temperature, ambient‑temperature‑tracking differential / high‑water differential (when room‑temperature tracking is active it shows "tracking differential"; otherwise it shows "high‑water differential"), ambient temperature (c.xx.x), alarm codes (Exx), and parameter codes (Fxx).
  Indicator Lights
  Unit status (Run)	ON: unit working; OFF: unit stopped.
  Normal operation signal (Alarm)	ON: no fault; OFF: fault present.
  Refrigeration signal (Refrigeration)	ON: compressor running; FLASHING: cooling demand exists but compressor not yet started; OFF: compressor off.
  Heating signal 1 (Heat1)	ON: low‑water heating on; OFF: heating off.
  Heating signal 2 (Heat2)	ON: low‑water heating on; OFF: heating off.
  Bypass valve (Bypass)	ON: bypass valve open; OFF: bypass valve closed.
  Buttons
  Up button (▲)	During parameter setting, modifies parameter values.
  Down button (▼)	Switches display; during parameter setting, modifies parameter values.
  On/Off button (On/Off)	Turns the unit on or off.
  Set button (Set)	In non‑fault state, pressing <Set> enters/exits the low‑water set temperature interface.

• After power‑on, the display shows software version information (F21/003/v100 /Axx) for about 7 seconds, then enters the temperature display state.

• Temperature Display

• The PV area shows the measured water temperature; the SV area shows the low‑water set temperature / tracking differential / high‑water differential / ambient temperature.

• Low‑water interface: PV shows low‑water measured temperature, SV shows low‑water set temperature.

• High‑water interface: PV shows high‑water measured temperature, SV shows tracking differential / high‑water differential (when room‑temperature tracking is active it shows tracking differential, otherwise high‑water differential).

• Ambient temperature interface: PV shows ambient temperature, SV shows "c."

• Press the ▼ button to cycle through low‑water, high‑water, and ambient interfaces. If no operation for 30 seconds, it automatically returns to the low‑water interface.

• Note: If the ambient temperature probe is not used, the ambient interface is not displayed. "d." is the code for high‑water differential, and xx.x is the temperature value (distinct from tracking differential); "c." is the code for ambient temperature.

• Fault Display

• When a fault is detected, the display alternates between the temperature reading and the fault code "Exx". If multiple faults exist, they are cycled automatically. When a fault code is displayed, pressing the <Set> button silences the alarm.

• Fault codes and descriptions are as follows:

• Fault Code	Fault Name	Detection Condition	Action	Reset
  E01	Low‑water probe fault	Detected after power‑on	Alarm, unit stop	Manual reset
  E02	Low‑water over‑temperature fault	Detected after power‑on	Alarm, stop low‑water and high‑water electric heating	Auto reset
  E03	Compressor fault	Detected after [F19 compressor fault detection delay] time from compressor start	Alarm, compressor stop	Auto reset
  E05	Flow alarm	Detected after power‑on	Alarm, unit stop	Auto reset
  E08	Low‑water under‑temperature alarm	Detected after power‑on	Alarm, compressor stop	Auto reset
  E09	High‑water probe fault	Detected after power‑on	Alarm, unit stop	Manual reset
  E10	High‑water over‑temperature alarm	Detected after power‑on	Alarm, stop only high‑water electric heating	Auto reset
  E11	High‑water under‑temperature alarm	Detected after power‑on	Alarm, compressor stop	Auto reset
  E12	Ambient probe fault	Detected after power‑on	In constant‑temperature mode: alarm only, no action; in room‑temperature tracking mode: alarm, unit stop	Auto reset
  E13	Ambient over‑temperature fault	Detected after power‑on; alarm when ambient ≥45°C, auto reset when ≤40°C	In constant‑temperature mode: alarm only, no action; in room‑temperature tracking mode: alarm, stop high‑water electric heating	Auto reset
  E14	High‑water flow alarm / other multiplex alarm	Detected after power‑on	Alarm, unit stop	Auto reset

• Note: For faults requiring manual reset, press the <Set> button to reset the fault; the unit will start automatically once the fault is cleared.
