PROGRAMMING THE ST620
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.
