HEATING CIRCUIT'S SETUP PARAMETERS
BioClass HM
is equipped with an electronic controller to manage efficiently the automatic functioning
of the boiler. It also has the following additional parameters to regulate the heating circuit connected.
They only may be modified by a person with sufficient technical knowledge of the meaning of each
parameter. Any inappropriate setting of a parameter of
“Technical Menu”
can cause a serious
malfunctioning of the boiler and could cause damages to people, animals or things.
13.1
Heating pump post-circulation time (P.15)
This function keeps the heating pump (
BC
) running for a period of time after deactivating the
heating service, to avoid the overheating due to the temperature inertias of the heating
installation. By means of parameter
P.15
the period of time that the pump continues to operate
may be set. The range of values selectable is 0 - 40 minutes (by default 3 minutes).
13.2
Boiler's pump operating mode (P.18)
The electronic controller allows to select between two operating modes of boiler's circulating
pump (
BC
) by means of
P.18
parameter of the
“Technical Menu”
. The following operating modes
can be selected:
P.18
= 0 => Standard mode: The circulation pump will be run depending if the heating demand
is activated or not.
P.18
= 1 => Continuous mode: The pump continues to run provided that the heating mode is
enabled (boiler temperature set point different to OFF). If there is room thermostat
or remote control connected to the boiler, the electronic controller will regulate the
burner functioning according to the heating demand, keeping the pump running
continuously.
13.3
Minimum boiler water pressure (P.19)
BioClass HM
is equipped with a water pressure sensor that makes possible to know the pressure of
the boiler. If the pressure descends below the value set at
P.19
parameter, the electronic controller
locks out the functioning of the boiler and
E-19
alarm code is displayed (see “
Safety lock-outs
”). The
range of values selectable is 0.1 - 0.5 bar (by default 0.5 bar).
13.4
Maximum heating flow temperature of mixed circuits (P.27)
The electronic controller allows to select the maximum heating flow tempetature for mixed circuits
installed in the boiler with an optional Bio Hydraulic Kit. By means of parameter
P.27
the maximum
heating flow temperature may be set. The range of values selectable is 45 - 80 ºC (by default 45 ºC
for mixed circuits)).
