INTRODUCTION

Highcool series cassette split systems are supplied as standard with the
Wired 7 Day Controller.

This controller is a sophisticated device designed to provide easy opera­tion to a Highcool series cassette split system.

At its simplest, with the front panel shut, the controller can be used to
display relevant information about the units operation and allow the user
to switch the unit on and off.

Opening the controller front panel allows all of the controllers functions
to be accessed. Pressing any of the buttons below the front panel once
gives User Level Access. Pressing and holding certain buttons will give
Service Level Access.

At its most sophisticated the controller can switch the unit on or off at
different times each day of the week (or not run the unit at all on some
days). It can tell you what the unit is doing and whether it has a fault—
even what that fault is!

This manual is designed to show how the 7 Day Wired Controller can be
used to operate your Highcool cassette split system in order to get the
most from it.

Appendix 2

Notes for Engineer

• The controller is provided with special screws for fixing it to the
wall. Please use these to avoid damaging the controller.

• The controller uses Low Voltage control cable—avoid running
this close to High Voltage cables in order to avoid interference

• The controller uses the RS485 data protocol. The cable colours
are Earth—Black, A—Green, B—Yellow, 12V—Red

Appendix 1

Fault Codes

The Error Check display area of the LCD display may, in the event of a fault, show the
symbol of a spanner and a fault code. This is a list of fault codes in order for you to
advise your service and maintenance engineer of the likely problem. Not all faults will
generate a fault code. Faults are divided into two types as below.

Recoverable Errors—P Codes

These faults will not always stop the unit but will affect its performance. They will clear
if the problem resolves itself.

Critical Errors—E Codes

These will cause the unit to shut down and should be investigated by an engineer as
soon as possible.

Repair—Critical Failure Requiring Investigation by an engineer

In the case of a Pr03 or Pr08 failure investigate yourself by checking the condition of the
filter and cleaning if necessary. Prolonged operation in cooling with a set temperature below
21C or heating above 26C can also cause these conditions.
In case of a Pr04 failure investigate yourself whether the outdoor unit airflow is obstructed.
