11 CONTROL AND SAFETY EQUIPMENT
g
Important!!
The subjects described in this
chapter apply to each boiler module.
11.1 General
Each boiler module is supplied with a standard set of
defaults pre-programmed for normal operation but can
be tailored by the Engineer to suit most site conditions.
These values are set and read, using the built-in instru-
ment panel or with a notebook computer or PDA (with
optional software and interface).
For security the control has three levels of access:
1. User level - free access
2. Service level - access with service code by qualified
personnel
3. Factory level - access by PC with factory code
(Remeha only)
