4 Description of the product
4.1 General description
The Quinta Pro boiler has the following characteristics:
High-efficiency heating.
Limited emissions of polluted substances.
Ideal choice for cascade configurations.
Option to produce domestic hot water using a separate hot water appli­
ance.
4.2 Operating principle
4.2.1 Circulating pump
Model not supplied with circulating pump
The boiler is supplied without a pump. Take the boiler resistance and sys­
tem resistance into account when selecting a pump.
Caution
The pump may have a maximum input of 200 W. Use an auxiliary
relay for a pump with greater power.
See
Technical data, page 13
If possible, install the pump directly under the boiler on the return connec­
tion.
For more information, see
Connecting the heating circuit, page 23
Pump settings
The pump settings for a modulating circulating pump controlled by the
control unit can be modified using parameters
and :
If there is insufficient flow in the radiators or if they do not warm up com­
pletely, the minimum pump speed can be increased using parameter
.
If there are audible flowing noises in the system, the maximum pump
speed must be lowered using parameter
(bleed the CH installa­
tion first).
Caution
The pump may have a maximum input of 200 W. Use an auxiliary
relay for a pump with greater power.

Changing the parameters at installer level, page 54
4.2.2 Cascade system
The boiler is ideally suited for a cascade system. There are a number of
standard solutions available.

4.2.3 Water flow
The modulating control of the boiler limits the maximum temperature differ­
ence between the flow and return and the maximum rise velocity of the
