4 Description of the product
4.1 General description
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 Operating principle
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
3
/h. If progres
sive calorifier control is activated with parameter
, then maintain a
minimum water flow of 0.8 m
3
/h.
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.
