Introduction

The controller is the compact device 

that makes it possible to control units 
for single-circuit air-to-air condition-
ing.

 
  Pay special attention to the usage 

regulations marked by the word 
“DANGER” or “WARNING” or by the 
“safety symbols“, as failure to respect 
them may lead to harm to people

the information given in this manual.

•   Installation and maintenance must 

be carried out by expert and quali-
fied personnel, according to the legal 
requirements in force in the country of 
installation for the electrical/electron-

the manual easier by drawing the read-
er's attention on the situations posing 
risks that cannot be avoided or sufficient-
ly limited by adopting protection meas-
