PART 1. GENERAL INFORMATION
APS
Air pressure switch
BCB
Boiler Control Board
BDB
Boiler Display Board
Blocking
Limit situation is touched, boiler OFF;
when the safe situation is restored, boiler On.
CCB
Cascade Control Board
CDB
Cascade Display Board
CH
Central Heating
Condensate
Water vapor generated as a product of combustion,
which has a low pH.
DHL
Two independent sensors (high limit and outlet water)
in a single well
iDHW
Indirect Domestic Hot Water
Diverter valve
Motorized valve with spring return
DHW
Direct Hot Water production (instantaneous)
Hard Lock Out (HLO)
A significant error or issue with the appliance or system,
such as multiple failures to light or an unsafe pressure
differential. An error code at this level will trigger a shutdown
of the affected appliance(s). Service or repair is required.
HLO
Hard Lock Out—Manual reset needed to restart the
appliance
HMI
Human Machine Interface
Hysterese
Blocking set temp offset temperature—
hysterese is starting temperature for the boiler.
ICM
Interface Cascade Manager (with or without WiFi)
Indirect Tank
Sanitary hot water tank with a built in heat exchanger
often used as a component in an iDHW system
INI
Baseline data initialization, runs by default every 14 days
Masterless Lead-lag System
In a multi-appliance system this control system will work
all connected appliances as one large team. This insures
smooth distribution of the work load and even aging of all
appliances connected within.
In addition, proprietary software manages common
vented systems insuring equal back-pressure on all
connected appliances and safe operation in the event
of a component failure of one or more of connected
appliances.
Modbus
For Ethernet or RS232 or RS485 bus system for Lead and
Leg communication
Offset
Overriding temperature above set blocking: boiler OFF
PAVO
Zone controller
PCB
Printed circuit board—burner control board
Soft Lock Out (SLO)
Manual reset or appliance reset needed for restart
Tank
Domestic Hot Water Tank without internal heat exchanger
3-way-valve
Motorized valve: turning to the right and to the left
Parameter
P followed by a letter and number (Ex: PS18 = parameter
S-18)
n.a.
Not applicable. Constant value.
TBD
To be defined
Z-INI
First INI process
