Switching the radiator on/off
The thermostat has four keys and a display.
The On/Standby 14 key is used to switch the thermostat
on or switch it to standby. When the thermostat is switched
to standby, a flashing dot appears on the display. When the
thermostat is on, the display shows the time and program,
the weekly program mode or the temperature setting (in
the other modes). When switching from standby to on, the
buzzer is activated and a beep sounds, which lasts approx.
1 second. When switching from on to standby, the buzzer
is also activated and two short beeps sound at an interval of
approx. 0.5 seconds.
