Changing the Default Time and Temperature Program
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.
How to access the PROGRAM menu
To access the menu screens, press the OK key twice. The first menu
displayed is the PROGRAM menu. Press the OK button to select.
Initially, the numbers for the Weekdays will be selected and flashing –
you can scroll through all the various options for day selection
weekdays (1-5) weekends (6-7) all 7 days (1-7) 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.
