• The MPCQ Platinum has two levels of heat. The Day Time level is used when a
building is occupied and people are active.
• The Night Time (Setback) level is used when a building is not occupied, or when
people are sleeping.
• The MPCQ Platinum can have up to four Day Time and four Night Time (Save)
periods for each individual day of the week. The MPCQ Platinum will show which
period is being edited on the 2nd line of the display.
• Every time the MPCQ Platinum updates the clock time, it checks the Day/Night
program. If there is a matching Day/Night time programmed, it sets the heat level
accordingly, otherwise, the heat level is not changed.
• If an office building is unoccupied all weekend, simply set the last Night setting (8:00
PM on Friday). Then, set all the Saturday and Sunday programs to **:**
