4.3.8.1 BACnet
The BACnet menu allows you to view the
configuration
and
change
the
BACnet
parameters.
In order to configure the VOLTMAX boiler to
your BACnet management system, you must
activate the function.
You must then enter the correct baud rate. Ex:
For a BACnet MS / TP communication protocol
with a
Metasys
system the default baud rate is
38400. You must enter the correct MS / TP
address. Ex : For a BACnet MS / TP
communication with a
Metasys
system, the
address is 5.
The names of the BACnet variables used by the
program are listed in the tables below. Variables
beginning with AV and BV are read variables,
while variables beginning with "W" are editable.
For more information on the BACnet protocol,
please refer to the appropriate documentation.
4.3.9 OCCUPATION
Setting the temperature-lowering period.
4.3.9.1 Occupation setting
This function allows the boiler water temperature
to be lowered for defined periods without having
to lower all the thermostats of the building. This
function can be activated and deactivated within
the menu
Occupation
under
Occupation
mode
. This function allows the set-point
temperature to be lowered when the boiler is
within the hours specified in the
Schedule
Setting
menu. The temperature drop (the value
should be negative) in the set-point can be
changed in the
Occupation Setting
menu.
The
SCR model
allows the connection of a
contact (OCC Contact) on the controller allowing
the use of an external timer to control the
OCCUPATION
function.
The
Contact OCC.
option activates the
operating mode using an external contact
(switch).
Ex: When the contact (switch) is open at the
OCC terminal, then the boiler will be in
temperature-lowering mode. (Night mode) When
the contact (switch) is closed, it will be in normal
occupancy mode (Day mode).
Force
is used to force the boiler to operate
normally (day mode).
A weekly schedule can be programmed under
the
Schedule setting
to modify the occupation
hours of the building.
4.3.9.2 SCHEDULE CONFIGURATION
Changing a Schedule
Use this menu to configure the building’s
occupation schedule. The schedule works on a
weekly schedule (Monday - Sunday) and allow
only 1 lowering Set point periods. The first hour
represents the start of the occupancy period and
the second hour represents the innocupancy
periods.
Ex: In the case currently displayed between
07:00 and 17:59, the set-point temperature will
not be affected. On the other hand, from 18:00
to 06:59, the set temperature will be lowered.
When the building is not occupied for a full day,
you must enter this information as follows, so
that the stpt stay in the lowering mode.
