You can switch on and off the controller any time by briefly
pressing the button.
The first pressing of any function button always turns the display
backlight on, only the second pressing activates a given
function.
During programming, failure to press any button for 10 seconds
is the same as pressing the button .
Notes
Pulse-Width Modulation mode (PWM)
When changing hysteresis settings, you can enable PWM mode.
In PWM mode, the controller switches on the heating device in
cycles to minimize temperature fluctuations. The controller
monitors the temperature rise and drop time.
Temperature
Time
Preset
temperature
Room
temperature
With these values determined, the controller switches the heating
device on and off in cycles that enable maintaining temperature as
close to the setpoint as possible.
CAUTION: In PWM mode, the controller can switch on the heating
device even though the temperature in the room is higher than
preset temperature. This is because the PWM algorithm tries to
maintain the preset temperature and stays ahead of the heating
system behaviour.
