11.5.9 Scheduled Setback (USER Level Access)
The
SCHEDULE MENU
allows the user to program the unit to automatically lower, or setback,
the operating setpoint when a facility is not occupied, or the use of hot water is curtailed.
1. Press and hold the
HOME
button for 3 seconds to enter the Control System Menu. Use the
NEXT ITEM
button to scroll to the
SCHEDULE
menu. Activate the schedule function by first
turning on the
HEAT SCHD
using the arrow buttons.
2. There are four setback schedule types: 24hr, 5-2, 5-11 and 7DAY. The 24hr schedule
(default) is a daily schedule that will follow the same program every day of the week. All
other schedule types are selected using the arrow buttons. The 24hr schedule allows for a 2
or 4 EVENT/DAY. The 2 event day provides for one occupied time and one unoccupied time
per day. The 4 event day allows for two occupied times and two unoccupied times per day.
NOTE:
Unoccupied setpoints are programed in the same manner as occupied setpoints.
For example, a 24hr type and a 4 event day schedule might look like this:
a) The 1
st
occupied time begins at 6:00am and the 1
st
unoccupied time begins at 11:00am;
therefore, the occupied setpoint will be used between 6:00am and 11:00am.
a) The 2
nd
occupied period begins at 4:00pm; the 2
nd
unoccupied time begins at 10:00pm.
b) Between the 1
st
unoccupied time of 11:00am and the beginning of the 2
nd
occupied
period, the unoccupied setpoint will be used.
c) At 4:00pm the 2
nd
occupied period will begin and continue until 10:00pm.
d) From 10pm until 6:00am, the unoccupied setpoint will then be used.
Note: Schedule times are identified as occupied (
Occ
) or unoccupied (
UnOcc
) here.
3. The 5-2 schedule type provides for a 2 or 4 EVENT/DAY but also allows for one schedule to
be followed Monday
–Friday and another on Saturday and Sunday.
4. The 5-11 schedule type provides for a 2 or 4 EVENT/DAY but also allows for one schedule to
