4: Running the Programmer:
4.1: To run the programmer:
Move the SET switch to RUN. The run pointer on the display points to AUTO. “AUTO” indicates that the
programmer will switch on/off at the times entered. Press the SELECT button. The run pointer moves to ONCE.
“ONCE” indicates that your system will start at the first ‘on’, (CH ON 1) and remain on until the last ‘off’. This is an
“on by day”
and
“off by night”
option. Press the SELECT button again. The pointer moves to ON. Your system will
remain on constantly, by day AND by night. Press the SELECT button again. The pointer moves to OFF. Your
system will remain off constantly. Press the SELECT button again. The pointer returns to AUTO.
4.2: Information Displayed when Programmer is Running:
When the programmer is running the display provides the following information: the current day; the current time;
the run option chosen, (AUTO, ONCE, ON, OFF); and whether your system is currently on or off. Additionally, if
you are running in AUTO, you are told which on/off period is current. For example: CH ON 2 tells you that you are
in the second heat period. There is also a red status light on the front of the programmer. When this light is on
your system is on, and when it is off your system is off.
5: Additional Functions:
EXTEND & ADVANCE are functions you may find useful. They operate in AUTO mode and are explained below.
5.1: ADVANCE:
If your system is ‘on’, pressing ADVANCE will switch it off. It will remain off until the next ‘on’ time.
If your system is ‘off’, pressing ADVANCE will switch it on. It will remain on until the next ‘off’ time.
“ADVANCE” is visible on the display. If you press ADVANCE again, the ADVANCE is cancelled.
5.2: EXTEND:
If your system is ‘off’ pressing EXTEND will reactivate your system for one hour, (or until it reaches the next
programmed ‘on’, whichever comes first). If you press it twice your system will come on for two hours and if you
press it three times your system will come on for three hours. Pressing it four times will cancel the EXTEND
function.
“EXT 1”, “EXT 2”, or “EXT 3” as appropriate appear on the display.
If your system is ‘on’, pressing EXTEND adds an extra hour to the normal ‘on’ period. If you press it twice, two
extra hours are added and if you press it three times, three extra hours are added. Pressing it four times will
cancel the EXTEND function.
“EXT 1”, “EXT 2”, or “EXT 3” as appropriate appear on the display.
6: General:
6.1: Power Failure:
The programmer has a memory backup that saves all settings for up to one year following loss of mains power. In
the event of longer power-cuts the date, time and on/off settings will have to be re-entered.
6.2: Maintenance:
Your programmer is a maintenance free device. In the event of a minor problem such as loss of display or
programmer hang-up, press and hold the RESET button for 2 seconds. This will return your on/off settings to
default settings. You will have to re-enter your on/off times. In the event of a more serious problem contact a
professional. Do not attempt to remove the programmer from the wall as removal results in live wires being
exposed on the wiring plate.
Note 1: Your programmer set-up can be altered. This action can only be performed by a qualified professional.
