Setting Controller Date And Time; Internal Daily Scheduling; Holiday Scheduling; One Event Scheduling - McQuay MicroTech II Operation Manual

The next four sections: "Setting Controller Date and Time",
"Internal Daily Scheduling", "Holiday Scheduling", and One
Event Scheduling" describe functions related to the internal
unit scheduling functions. These are followed by a section
describing the optimal start function which can be use with
internal scheduling and network scheduling. This is followed
by two sections that describe the external time scheduling
and network time scheduling functions.

Setting Controller Date and Time

Table 15: Programmable Parameters
Keypad/Display ID
Menu Name Item Name
Time= hh:mm:ss
Time/Date Day= ddd
Date= dd-mm-yyyy
The MicroTech II controller uses the date and time to exe-
cute its internal scheduling functions. Once set, the battery
backed internal time clock keeps the current time regardless
of whether or not power is being supplied to the unit.
The time of day can be set by entering the hour (00-23),
minute (00-59), and second (00-59) into three fields of the
Current Time. Note that MicroTech II uses "military" time.
The day of the week is not adjustable. The Current Day is set
automatically by the controller based on the Current Date.
The current date can be set by entering the date (00-31),
month (01-12) and year (1999-2155) into the three fields of
the Current Date.

When the Occ Mode= parameter, described in "Auto/Man-
ual Operation" on page 45, is set to "Auto", and the unit is
not disabled for other reasons, it starts and stops according to
the controller internal schedule. One start and one stop time
can be set for each day of the week and for designated holi-
days. An example of how to use the keypad to enter or mod-
ify a schedule is given in "Getting Started" on page 6.
As shown in Figure 5, each daily schedule has four adjust-
able fields: Start Hour, Start Minute, Stop Hour, and Stop
OM 138
Minute. The schedule shown would cause the unit to start up
at 6:30 a.m. and shut down at 6:00 p.m. every Monday, Tues-
day and Wednesday.

Current Time
For continuous unit operation, the schedule fields can be set
Current Day
to "00:00-23:59." For no unit operation for the entire day, the
schedule fields can be set to "00:00-00:00" (this is the
Current Date
default setting).

Holiday Scheduling

Table 17: Programmable Parameters
Special operating hours can be scheduled for up to 16 holi-
day periods during the year by using the holiday scheduling
feature. (The wildcard character "*" in the above table could
be any number between 1 and 16.) Whenever a holiday
period occurs, the controller uses the Holiday Schedule start
and stop time for the period. For example, assume that
Christmas Eve occurs on a Thursday. The building is shut
down on both Christmas Eve and Christmas Day, but oper-

scheduled by setting the Holiday Schedule to "00:00-00:00"
