Operation Chapter 4
4.1 Outline description
An appliance from the :++5&'& series is a highly advan
ced heat recovery unit, specially designed for minimum energy
consumption and maximum comfort. This is achieved with the
aid of various electronic control systems. A control unit with mi
croprocessor controls and monitors the safe operation of the
appliance and ensures that the air quantities remain constant
and at the preset values.
The :++5&'& comes with a control panel with display, ena
bling stepless adjustment of the volume without having to open
the appliance. Moreover, information regarding the operation
can be read out from the outside of the appliance.

Chapter 5 Installation
5.1 Installation general
The appliance installation procedure can be summarised as
follows:
1. Siting the appliance (§5.2)
2. Connecting the ducts (§5.3)
3. Connecting the condensate discharge (§5.4)
4. Electric connection:
Connecting the multiple switch and, if necessary, the mains
power and the OpenTherm connector (§5.5)
The :++5&'& must be installed in accordance with:
• Quality requirements ventilation systems dwellings.
• Quality requirements balanced ventilation in dwellings.
• The regulations for ventilation of dwellings and residential
buildings.
• The relevant electrical safety regulations,
• The regulations for connection to interior sewers in dwel
