HYDROMOTIVE PRESSURE AND PRESSURE DROP
The
BioClass HM 66
boiler must be installed together with a Anti-condensation Kit, optionally
supplied by
DOMUSA TEKNIK
. The kit primarily comprises a high efficiency circulation pump and a
thermostatic mixing valve to ensure a minimum return temperature of 50ºC.
The
BioClass HM 25
and
BioClass HM 43
boilers do not need the Anti-condensation Kit.
24.1
High efficiency circulation pump
The pump can be adjusted in two ways:
1-Constant speed I, II, III (traditional mode):
The pump operates at a constant, pre-set speed.

Yonos Para (constant speed)
2-Variable differential pressure (
∆
p-v):
The setpoint value of the differential pressure H increases in a straight line between ½H and H
within the permitted flow margin. The differential pressure generated by the pump is
adjusted to the appropriate setpoint value of differential pressure.
