EARLY SHUTDOWN CURVES

Setting matches Vari Boost
SELECT Settings/<System Settings>/<More Settings>/Boost/ Vari+ESD
• Early Shutdown (ESD) is calculated based on the latest night schedule for that day. It allows the control to switch to the Night
setting earlier than the latest night schedule. This normally is useful in buildings where heat loss is minimal.
• The same curve setting that determines the Vari Boost also determine the Early Shutdown operation, but in reverse. The curves
cannot be set separately.
• Early Shutdown time decreases with colder outdoor temperatures.
• The maximum time spans for the Early Shutdown are half as long as the Vari Boost - ranging from 0 to 90 minutes instead of
0 to 180 minutes (compare vertical axis of the two graphs).
• If space sensors are available and the Space Lockout is set to enable, the ESD message may end sooner if the Space Average
reaches the Night Space Target. From that time,, the MPC Platinum will continue using the Night settings.

WARM-UP ENABLE AND LEARN

• The Warm-up Enable and Learn Features are only available through the Internet when the
Vari Boost or Vari+ESD Boost is set to enable.
• Warm-up adds additional time to the calculated Vari-Boost period to account for the time it
takes to establish heat. By default, it starts 15 minutes before the Vari Boost.
• If Learn is set to enable, the control will measure the Boost establishing heat time and then
use it as the Warm-up time before the next day Vari-Boost.
• Heat-Timer recommends setting the Warm-up to Enable and the Warm-up Learn to Yes.
