(1) Do not modify these factory settings unless absolutely necessary. For example, for modification of the boiler for: G20 (H gas) or G31 (propane),
high pressure systems, WTW coupling or CLV overpressure
(2) Factory setting depends on installation type
(3) The parameter is only displayed if the SCU-S191 and the solar control system are present
(4) The parameter is only displayed if the SCU-S191 is present
