Introduction

This document aims to comprehensively describe the operation of CLEVA remote control.

Warning
Installation, mounting and maintenance operations must be carried out by qualified, authorised and trained operators according to local regulations in each country.

Warning

This remote control is an electronic device and must be discarded according to applying European Directives and not as domestic waste.

Exclusively use the approved means.
Properly meet all applicable local regulations.

Specs

Operation

Operation mode/ ventilation screen
Once the remote control is switched on a welcome screen shows basic unit information, including software version and serial number. After 3s the main screen is shown as below:

Button	Description
1/5	Mode selection: occupied/ unoccupied/ temporary. Occupied mode : The unit will assume the temperature/ airflow set points corresponding to the hourly program set. Unoccupied mode : The unit will assume the temperature/ airflow set points corresponding to the unoccupied function . Temporary mode : allows fan boost for limited time only.
2/6	Mode selection: automatic /manual
3/7	Automatic mode: no function. Manual mode: allow to select temperature and airflow set points for comfort, ECO , unoccupied and unit stop .
4 / 8	Allow access to: Ventilation Temperature Notifications/alarms Clock

Occupied/ unoccupied/ temporary modes

Buttons 1 and 5 allow to switch among the following modes:

Occupied mode . The unit will assume the temperature/ airflow set points corresponding to the hourly program set only if the unit is running in mode. Temperature set points can be selected through the remote control. Airflow set points are factory-fixed to avoid any damage to the unit. Go to hourly program screen to it set up.
Unoccupied mode .The unit will assume the temperature/ airflow set points corresponding to the unoccupied function . The unit will run this mode unless the user changes it.

Button	Description
1/5	Mode selection: occupied/ unoccupied/ temporary. Occupied mode : The unit will assume the temperature/ airflow set points corresponding to the hourly program set. Unoccupied mode : The unit will assume the temperature/ airflow set points corresponding to the unoccupied function. Temporary mode : Allows fan boost for limited time only.
