S7999B, S7999C SOLA
Local Operator Interface
APPLICATION
The S7999B and S7999C are microprocessor-based touch-
screen Operator Interface (OI) displays that provide an
operator interface for monitoring and configuring parameters
in the Sola Hydronic Control and Sola Steam Control system.
The S7999B can be used to monitor an individual boiler but is
primarily used for multiple boiler applications in a lead/lag
arrangement. COM 2 port is available for Building Automation
applications. The S7999B display is flush mounted into a
panel cutout (8-1/8 in. W x 5-7/8 in. H). Wiring connections to
the S7999B are through a removable 9-pin wiring header.
The S7999C display is used for individual boiler monitoring.
The S7999C is mounted:
• onto a panel using the wallplate provided.
• from the front into a panel cutout (7.6 in. W X 5.4 in. H)
using 4 #6-32 screws and nuts (provided).
• From behind into a panel cutout (5.45 in. W X 4.3 in. H)
using 4 #6-32 screws, nuts and 4 standoffs (provided).
Wiring connections to the S7999C are made via a 4-pin
connector on the back of the display.
NOTE: If display S7999B is used to monitor a lead/lag sys-
tem, display S7999C can NOT be used.
