3.3.2.
The boiler is ideally suited for a cascade system. Remeha offers a
number of standard solutions for this. For example:
4 Cascade sets (quick assembly) for the installation of 2 to 4 boilers
next to each other.
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.
A calorifier can be connected to the boiler. The product range of
Remeha includes various calorifiers. Please contact us for further
information.
The calorifier can be connected to the boiler in two ways:
4 Using a three-way valve.
4 Using a calorifier pump.
3.3.4.
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
