6.6 More About Boost Mode
Boost mode is determined by two quantities that determine Boost
• Boost temperature
• Boost time
Boost time takes precedence over Boost temperature. Once the Boost period
expires, then the extra heating power is removed regardless of whether the
zones actually reach the configured Boost temperature.
NOTE
Boost only raises the temperatures of those zones that have a Boost
temperature configured.
Boost mode is only available while the system is in RUN mode.
The Boost command may be received locally through the console interface or
remotely via the remote console interface or the Quad IO card.
6.6.1 Manual Boost Display
When the manual Boost command is given, the Mode window shows BOOST
in black letters on a yellow background. The BOOST message displays
until Boost time period expires, after which the zones returns to normal set
temperature and the Mode window shows RUN.
