If more Local burner/boiler systems exist in the network than
can reasonably fit on the page, Previous page and Next page
buttons (see Fig. 45) are used to move between the burner/
boiler systems on the page. These buttons appear only when
the total number of burner/boiler systems exceeds the display
limit.

COMMISSIONING
Commissioning Process
Commissioning the R7999 using the S7999D System Display
requires the following general steps:
1. Connecting the R7999 to the S7999D and logging into
the system with a password. (This is the commissioning
password for the R7999 controller. The factory default is
"password" (without the quote symbols)). This prevents
unauthorized users from modifying the modulation curve.
2. Specifying the base configuration: one or two fuels, with
or without FGR.
3. Selecting system parameters such as Low Fire Hold.
4. Specifying the characteristics of the actuators and
setting the valve/damper endpoints for those actuators.
5. Creating a modulation curve (profile) for each fuel and
verifying it from maximum to minimum modulation.
(While you are commissioning the system, you must
monitor the burner operation with appropriate safety
instrumentation to verify the modulation curve.)
Commissioning Overview
The following table provides a step-by-step overview of how a
system is commissioned.
The Notes column in the table provide references to detailed
information when completing the more complex operations.
.
The S7999D requires you to enter the R7999
Commission password. The factory default password
is "password".
