CHANGING THE PROGRAMME TIMES
The Controller’s Central Heating 7-day timer has three time periods for each day of the week.
Each time period can be set at minimum intervals of 5 minutes.
The Controller will prevent the On and Off times from being entered in the wrong order.
Attempting to move the On time past the associated Off time, will cause the Off time to move
as well.
The Controller will not allow the three on-time periods to overlap. If the displayed On or Off
time flashes ‘LIMIT‘ while the time is being changed it indicates an incorrect time setting is
being attempted. Incorrect times could be:
-On time cannot be set before midnight of the current day.
-On time is clashing with the next period On time.
-On time cannot be set past midnight of the current day.
-Off time cannot be set before the On time in the current period.
-Off time cannot be set after the On time of the next period.
If a timing clash occurs while setting the time period, the incorrect time must be altered
before the current setting can be correctly entered.
The 3rd time period on any day may be extended into the next day. The Controller will not
allow this period to overlap the next day’s time periods.
The menu item CH Timer is used to configure the Controller’s CH timer; which has three
time periods for each day of the week.
On entry the display shows the current day on the first line. The ‘day’ will be flashing to show
it is the current item. Use the Left and Right keys to select a specific day. To view and edit
that day’s time periods, press the Boost key.
Note that any specific on-time period is disabled by setting the On and Off times to exactly
the same time.
On selecting a specific time setting, the display shows the time period ‘1st’,‘2nd’ or
‘3rd’and the On time setting on the first line. The period Off time is displayed on the
second line.
Use the Left and Right cursor keys to move between each of the On and Off times. As each
time becomes the current item, the digits will be flashing and the symbol ‘‘will be
positioned next to it. Using the Left and Right keys also moves between each available time
period as shown below:
1st 6:30
8:30 1st 6:30
8:30 2nd 12:00
12:00
3rd 5:30
10:30 3rd 5:30
10:30 2nd 12:00
12:00
The Up and Down cursor keys are used to increase or decrease the selected time in 5
minute intervals. N.B. holding either key down will cause the numbers to auto-scroll.
