10.1 Introduction to parameter codes
The controls platform makes use of an advanced system to categorise
parameters, measurements and counters. Knowing the logic behind these
codes, makes it easier to identify them. The code consists of two letters
and three numbers.
The first letter is the category the code relates to.
A
Appliance: Appliance
B
Buffer: Hot water tank
C
Circuit: Zone
D
Domestic hot water: Domestic hot water
E
External: External options
G
Gas fired: Gas-fired heat engine
P
Producer: Central heating
Category D codes are appliance controlled only. When the domestic hot
water is controlled by an SCB, it is handled like a circuit, with C-category
codes.
The second letter is the type.
P
Parameter: Parameters
C
Counter: Counters
M
Measurement: Signals
The number is always three digits. In certain cases, the last of the three
digits relates to a zone.
10.2 Changing the parameters
The boiler’s control unit is set for the most common central heating
systems. These settings will ensure that virtually every central heating
system operates effectively. The user or the installer can optimise the
parameters as required.
Caution
Changing the factory settings may adversely affect the operation
of the boiler.
10.3 List of parameters
10.3.1 CU-GH13 control unit settings - C 340
All tables show the factory setting for the parameters.
Important
The tables also list parameters that are only applicable if the boiler
is combined with other equipment.
