Programming Running mode
1.
Press the 'Program' button and then press the 'OK' button when option '1'
appears on the display.
2.
The next option screen allows you to choose which days of the week to
schedule. You can set all week days to be the same, setup week then
weekend days, or each day individually. Select the appropriate option by
using the Arrow keys to scroll and then pressing the 'OK' button. You will
need to return to the menu several times if you want to setup days individually.
3.
Next, the target temperature and setback temperature (on and o ) need
to be set for each 'heating cycle'. Once again, use the Arrow keys to scroll
and OK to select a temperature.
4.
Once this is set, you need to choose the periods of the day that you want
to be heated. Each one is referred to as a 'heating cycle' and is denoted on
the display by a series of blocks corresponding to the times of day marked
next to it. Set the first heating cycle by scrolling to select a start time and
pressing OK. Then select an end time and press OK. Running mode allows
up to 4 independent heating cycles. Each one of these needs to be set,
however, if you require less than 4, simply set the on and o times for
unwanted cycles to the same time which will e ectively cancel them.
