Operating principle

16
The Quinta Pro boiler is a high-efficiency wall-hung gas boiler with the fol­
lowing properties:
High-efficiency heating.
Option to produce domestic hot water using a separate hot water appli­
ance.
Limited emissions of polluted substances.
Ideal choice for cascade configurations.

4.2.1 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 11
If possible, install the pump directly under the boiler on the return connec­
tion.
For more information, see
Connecting the heating circuit, page 22

4.2.2 Cascade system

The boiler is ideally suited for a cascade system. There are a number of
standard solutions available.
Note
Contact us for more information.

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
flow temperature. As a result, the boiler is virtually unaffected by low water
flow. In all cases, maintain a minimum water flow of 0.4 m
sive calorifier control is activated with parameter
minimum water flow of 0.8 m

4.2.4 Calorifier connection

A calorifier can be connected to the boiler. Our range includes various cal­
orifiers.
Note
Contact us for more information.
Connect the calorifier to the boiler with a calorifier pump. A three-way
valve is not suitable due to the hydraulic resistance. An optional PCB is re­
quired to connect a calorifier pump.
