• To exclude the Boost on a specific day of the week, simply do not use the
#1 Day Time schedule . See "Schedules" on page 42 .
• When in Boost, the control displays a message indicating it . See
"Display Messages" on page 24 .
• The Early Shutdown (ESD) is used to switch to Night earlier than the last
Night Schedule . The control does that by starting to change the target
temperature to the Fast Cool Down setting earlier than the last Night
Time based on the outdoor temperature .
• If no Space Average exists, the ESD ends at the last Night Time
schedule .
• If Space Average exists, the ESD ends when the Space Average drops
below the Night Target .
• When in ESD, the control displays a message indicating it . See "Display
Messages" on page 24 .
Boost Modes
Off - Boost is always disabled .
Vari-Boost - This Boost begins earlier than the Day # 1 time . The
length of the Boost time depends on the outside temperature . During
the Boost period, the Multi-MOD Platinum increases the target
temperature by the number of degrees set by the Boost Adjustment .
• If the ambient building temperatures are too cold at the Day # 1
time, then increase the Boost Adjustment in increments of 10°F . If
the Boost Adjustment is turned all the way up, and it is still to cold
at the Day # 1 time, it might be necessary to reduce the Setback
setting . See "Setback" on page 34 .
• If it is too warm at the Day # 1 time, then decrease the Boost
Adjustment in increments of 10°F
Vari-Boost with ESD (Early Shutdown) - This feature is used in
commercial buildings where the building is unoccupied at night . The
Vari-Boost runs as indicated above . In addition, the ESD switches
the Schedule to the Night earlier than the latest Night setting .
• The warmer it is outside, the earlier the Multi-MOD Platinum shifts
to the Night setback .
• During the Early Shutdown the Multi-MOD Platinum uses the Fast
Cool Down setting as the target temperature .
• If the Multi-MOD Platinum has an Internet communication package
and Space Lockout has been activated, the Early Shutdown will
lower target temperature to either Minimum Water Temp setting or
70°F, depending on the Fast Cool Down setting, until the Space
Average has reached the Night Target .
• If Space Lockout has not been activated or no communication
package is available, the Target temperature will be the Night
Setback .
