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 opera-
tion 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.
