CAUTION
The pump may have a maximum input of 200 W. Use an
auxiliary relay for a pump with a larger input.
3.3.2.
System in cascade
The boiler is ideally suited for a cascade system. There are a number
of standard solutions available. For example:
4
Cascade sets (quick assembly) for the installation of 2 to 6 boilers
next to each other or 3 to 6 boilers mounted back to back on a free-
standing frame. When the boilers are mounted next to each other,
they can be mounted either on the wall or on a free-standing frame.
4
Low loss headers for a cascade system of 2 or 3 boilers (Quinta
Pro 45 and/or Quinta Pro 65). The flow and return of each boiler
can be directly connected to these.
Please contact us for further information.
3.3.3.
Calorifier connection
A calorifier can be connected to the boiler. Our product range includes
various calorifiers.
Please contact us for further information.
The calorifier can be connected to the boiler in two ways:
4
Using a 3-way diverting valve.
4
Using a calorifier pump.
3.3.4.
Water flow rate
The boiler’s modulating control system limits the maximum difference
in temperature between the heating flow and return and the maximum
speed at which the flow temperature increases. For this reason the
boiler is, so to speak, insensitive to a flow which is too low.
In all cases, maintain a minimum water flow of 0.4 m
3
/h.
If DHW regulation is progressively activated with parameter
p35
,
then maintain a minimum water flow of 0.8 m³/h.
