Introduction

Check that the following papers have been supplied with the product:
- User's Manual
- Installation
If, after reading the guide, you have any other questions concerning installation of the product,

The system is controlled using the multifunctional CTS 700 control panel.
The purpose of these instructions is to explain the menus and options available when using CTS
700.
As these instructions are designed to apply to different models, you may find descriptions of func-
tions and facilities that are not available on your system.
NB: If the system is damaged in any way, the damage must be inspected and repaired by an au-
thorised technician.
The system is delivered ready to run.
The factory settings are intended to meet most users' needs and it should therefore not be neces-
sary to change any settings other than the main menu settings.

signal to the system when extra ventilation is required and 2) an output signal to an EM box (if any)
or motor valve.
All settings determine the interval for how long a user selection may run.
There are four basis settings in the weekly schedule.

down ventilation systems, an external fire connection will be able to switch off the system.

and the central heating heat pump.
