Parameter setting

For the regulator to be able to recognize this installation you need to
set the following parameters as shown in the table.
Installation ID
– Setting mode = INSTALLER
(please refer to the "Parameter setting levels" paragraph)
Par Description
140 LPB address
148 Timer
170 H1 input management
173 Function of contact connected to H1
NOTE: In the case of non-condensation boilers, the return tempera-
ture must be raised in order to avoid the problems related to the flue
gas condensate. To do so, the OEM 22 parameter must be modified.
– Setting mode = MANUFACTURER
(please refer to the "Parameter setting levels" paragraph)
Par Description
22 Min. limit of cascade return temperature
3.2.4 Verifying the correct recognizing
To make sure the regulator has correctly recognized the installation on
the basis of the input parameters, display the "Installer" parameter on
line 53.
Installation n° 34 must appear (n° 36 in the case of DEWY EQUIPE).
