This code programs water temperature setback schedules for either the entire week or for each day of the week. This feature is primarily used for night, or whenever the building is empty.

The control panel uses 24 hour military time. Choose the hour (on the hour) for setback to begin, say 6 p.m., or 1800 hours in the example above. Then enter the amount to set back, which can be anywhere from 1°F to 99°F. The example above assumes 5°F. After entering the “on time", and the degrees to be setback, press the enter key (#). When # is pressed at the end of each entry, it not only enters the values into program memory, the display is advanced to the next slot.

Next, input the time to turn the setback off to return to normal running conditions, 6:00 am in this example. The panel now knows to lower the water temperature by 5 degrees at 6 p.m. and return to the original temperature at 6 a.m.

An important feature of the panel is that it begins the warming process two hours prior to the programmed time. Thus, the panel will begin monitoring both the outside and Return Line Temperatures at 4:00 a.m to determine the most fuel efficient way to reach the desired water temperature by 6:00 a.m..

Each of the codes 30 through 37 can handle four complete on and off setback schedules every 24 hours. Remember that code 30 sets the time for all seven days of the week, and 31 through 37 sets each individual day for its own setback. A simple way to customize certain
