12Α.13.2. Time adjustment in Sleep Mode
• In 10V4, the user can make use of the Off-Timer to extend the Sleep Time from
7 hours to 12 hour (max). The operation of the new “Extended Sleep Mode” is
illustrated by the graphs below.
• Case 1 is the Standard Sleep Mode, which is the only sleep mode in previous
version of MCU. The A/C unit simply works for 7 hours, then goes to SB.
• Case 2 is the new Extended Sleep Mode. If an active Off-Timer is set to turn off the
A/C between 7-12 hour, relative to the starting of Sleep, the Sleep time is extended.
And, instead of going to SB at the 7th hour, the A/C will work until reaching the Off-
time.
• Case 3 is an exception to case 2. The Sleep Mode will not be extended to the Off-
Time when the Off-Timer is preceded by an On-Timer, which is also between 7-12
hour.
