3.7.2 Setting parameters
Set the parameters as shown in the table to ensure that the con-
troller recognises the system, on both the MASTER (parameter
140=1) and the SLAVES (parameter 140=2,3).
MASTER:
System identification
–
Setting mode = USER
(refer to section on parameter setting levels
)
–
Setting mode = INSTALLER
(refer to section on parameter setting levels)
N.B.:
In the case of non-condensation boilers, the temperature of return
to the boiler must be raised and care must be taken to prevent pro-
blems related to condensation of flue gases using parameter 22 0EM.
–
Setting mode = MANUFACTURER
(Refer to section on parameter setting levels
)
SLAVE 1:
System identification
–
Setting mode = USER
(refer to section on parameter setting levels
)
–
Setting mode = INSTALLER
(refer to section on parameter setting levels
)
–
Setting mode = MANUFACTURER
(Refer to section on parameter setting levels
)
NOTE:
If there are only two boilers, use the settings for SLAVE
1 only.
SLAVE 2 (applies to third boiler only):
System identification
–
Setting mode = USER
(refer to section on parameter setting levels
–
Setting mode = INSTALLER
(refer to section on parameter setting levels
)
–
Setting mode = MANUFACTURER
(Refer to section on parameter setting levels
)
