3.2.1 Selecting the plant type
The first setting to be made is always the plant type because when selecting the type of
plant, the majority of settings are reset to their default values.
Following will not be reset:
• Texts
• Business card
• Device name
• Terminal types
• Time switch
• Holiday program
The RMH760B contains 41 plant types. If required, every type of plant can
subsequently be changed or complemented via "Extra configuration".
With basic type H, no configuration is predefined. The plant type is to be selected if the
subject plant differs considerably from the preconfigured plant types, so that the effort
required for an adaptation would be greater than the effort required for manual
configuration.
The plant type is made up of the letter "H" and a 2-digit numeral (e.g. H4-5):
• The first digit defines the type of heat generation or heat distribution
• The second digit defines the type and number of internal consumers
First digit of plant type
