radiators tends to increase. By keeping ÄT constant, the
reduction in the flow rate is obtained by changing the
operating curve, which produces a lower return
temperature that in turn favours high boiler performance
and the reduction of electricity consumption.
Operationally:
- Access parameter 90
- Set the parameter at a value between 2 and 40 (normally
between 10 and 20).
3 - VARIABLE SPEED CIRCULATION UNIT WITH
MAXIMUM FIXED MAXIMUM SPEED MODE (P90 = 1)
In this mode the modulating circulation unit works
constantly at maximum speed.
It is used on plants with a high load loss in which the
boiler’s head must be used as much as possible in order
to guarantee sufficient circulation (plant flow rate at
maximum speed lower than 600 litres per hour).
This is used when bottles of mixture are involved, with
high flow rates in the circuit downstream.
Operationally:
- Access parameter 90
- Set the parameter = 1
4 – EXCEPTIONAL USE OF A STANDARD CIRCULATION UNIT
WITHOUT SPEED ADJUSTMENT (P90 = 0)
This mode must be used in exceptional cases in which the boiler
is to be used with a traditional circulation unit without a speed
adjustment. It presupposes that the adjustable speed circulation
unit has been removed and replaced with a non-adjustable speed
circulation unit. Warning !!!! the BE06 board connected to
connector CN9 must be removed and replaced with a connector
with a jumper to be inserted into connector CN9. This latter
connection is obligatory and if not formed may cause the system to
malfunction.
Operationally:
- Access parameter 90
- Set the parameter = 0
