Radio Controlled Clock; Control Menu - Salus S Series Instruction Manual

SETTING DST
Once you have set the date and time you will be asked to set the DST to ON/OFF, the screen will now
change to T_Zone. On this menu you can choose from -1,0,1,2 or 3hrs by using the Touch Ring to
scroll, and confirm the setting by using the OK button. Press the Arrow key to return to the previous
screen display, or do nothing for 10 seconds and the ST620 will return to NORMAL mode.

RADIO CONTROLLED CLOCK

The ST620 time and day of the week settings are updated automatically every day
(at 12:00 AM or 2:00 AM) by the use of a very accurate internal
Radio Controlled Clock.
The RCC status indicator will be displayed for 10 minutes during clock updates.
The indicator will flash during the time update process, after which the indicator
will be displayed for 5 minutes before turning off.
The time and date will also be automatically updated when the ST620 is
powered up, or after the Reset Button is pressed.
If for any reason the ST620 fails to automatically update the time setting, then the data stored in the
internal memory will be used. The clock settings can also be changed manually if required – manual
settings will be overwritten at the next successful automatic update.

CONTROL MENU

By selecting the Control menu, the user can change the
control method used by the thermostat - either ON/OFF
or Pulse Width Modulation(PWM). On entering the menu,
scroll to select the preferred option (ON/OFF or PWM
control), and confirm the choice using the OK button. Use
the Arrow key to return to the Menu Option display. PWM
mode should only be selected by the Engineer carrying
out the installation, or other qualified person.
