B-C: Boiler control via 0-10VDC + plate heat exchanger

Description



R3456 EVO with plate heat
exchanger

Tips



Complete accessory kits with plate
heat exchanger are available for

∆T=10-20K (see chapter

„Accessories“).



The primary circuit should be de-
signed for ∆T=20K, this guarantees

a high boiler efficiency.



When the secundary circuit is de-
signed for a ∆T smaller than 20K,

the flow temperature of the plate

heat exchanger will be lower than

the flow temperature of the boiler.

This should be taken into consider-

ation during the design stage.



The plate heat exchanger should
be positioned close to the boiler, to

avoid a negative influence on the

temperature control quality.



In case of a boiler room installed
on the roof, the boiler may never

be hydraulically connected at the

highest point of the installation.
