Salus ST620 Owner's manual

PROGRAMMING THE SALUS ST620/ST620RF
The ST620 offers great versatility with its programming options,
allowing the user to programme the ST620 to operate on an individual,
5/2 or 7 day control cycle. The programmable thermostat has a default
set of Programmes that have been designed to meet the needs of most
users. If these default programmes are not suitable for your particular
situation, reprogramming the ST620 with your own settings is a very
straightforward operation. To start programming the ST620, press the
OK key when in NORMAL mode. This will by default select the
PROGRAMME menu - press the OK key once more to start the
programming process. Initially, the Weekdays will be selected and
flashing – you can scroll through all the various options for day
selection (Weekdays, Weekend, 7 days, or individual days) by using
the Touch Ring. As usual, pressing the OK key will select the desired
option.
After correct selection of the day option, the ST620 display will change
to the next programming screen. These screens allow you to set the
required time and temperature settings to provide optimum control for
your heating system.
The hour setting will be the first setting that needs to be adjusted, and
this will easily be seen because the ‘hours’ section of the time will be
flashing. Using the Touch Ring, scroll up or down to adjust the hour to
the required setting and then press the OK key to confirm. After
confirming this setting the ‘minutes’ section of the time will then start to
flash. Change this setting using the Touch Ring in the same way that
you changed the hour setting, confirming your setting with the OK key.

Finally, set the desired temperature setting by scrolling with the Touch
Ring and again confirm with the OK key.
Following this sequence you will have set up Programme 1 – the
ST620 display will then move on to Programme 2. Continue to add your
desired settings for each of the programmes through to Programme 6
in the same way as Programme 1 (hour, minutes, and temperature). If
you decide to enter settings for individual days rather than Weekdays
or Weekends, the ST620 also offers a time saving COPY function that
allows the user to copy settings from one day to another.
After entering the settings in Programmes 1 to 6 for Monday, the ST620
display will change to display a COPY TO screen. On this screen, scroll
to the day that you want to copy the settings to using the Touch Ring,
and then confirm this by pressing the OK key. The ST620 will then
move to the next day and ask if you would like to copy again. In the
example here, Monday has been programmed, and the next day that
has not been programmed is Tuesday. Once the settings for Tuesday
have been programmed by copying, the settings can then be copied to
Wednesday, and so on. Pressing the Arrow key at any time will return
the ST620 to the previous screen. Once all the days have been
programmed, the ST620 will revert to NORMAL mode.
PLEASE BE AWARE THAT EACH OF THE PROGRAMME TIME
SETTINGS MUST BE IN SEQUENCE: for example, Programme 3
cannot be set with a time earlier than Programme 2. If this situation
occurs, then the ST620 may operate in an unpredictable way. The
programmable thermostat will return to NORMAL mode after 10
seconds if no Key is pressed or if no movement is detected on the
Touch Ring. In this case, the Programmes will not be updated.
