Installation and operation manual BM mini
Starting of operation with given values (pre-setting)
E.g.
Given values:
Heat requirement of underfloor heating system
2000 W
Supply temperature of radiator-/boiler system
70°C.
Return temperature of underfloor heating system
40°C
Difference pressure of the radiator-/boiler circuit
10 kPa
Specific heat capacity of water
1,163
W
/
(Kg x K)
Wanted values:
Flow from the radiator-/boiler circuit =
m = Q/(c x dT) = 000 W / (1,163
W
/
(kg x K)
x 30 K) = 58 l/h
Pre-setting:
If the difference pressure from the radiator-/boiler circuit at the inlet and
outlet of the BM mini is 10 kPa and the flow requirement of the BM mini is
about 60 l, the mixing valve pre-setting has been opened by 1,6 turns.
