11.0 CONTROL AND SAFETY EQUIPMENT
11.1 General
The boiler 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 instrument panel or
with a laptop/computer or PDA (with optional software and interface).
For tamper proofing and security reasons the control has three levels of access:
1. User level - owner access
2. Service level - access with service code by qualified personnel
3. Factory level - access by PC with factory code
11.1.1 Instrument panel layout
The instrument panel consists of (see fig. 25):
1. Operating switch
2. PC/PDA connection for monitoring
3. Facility for incorporating a weather compensator
