Configuration settings:
backlight colour, hysteresis, delay, offset, clock calibration
Configuration settings are presented for changing in the following order
To enter the configuration settings change mode press the buttons simultaneously
and hold them for 5 seconds until the display backlight starts flashing.
1. BACKLIGHT COLOUR CHANGE
Flashing backlight indicates that you can change
the backlight colour with the buttons.
Confirm the setting by pressing the button.
The regulator will proceed to change the next parameter.
2. HYSTERESIS CHANGE
Hysteresis is designed to prevent switching the con-
trolled device on and off too frequently due to minute
fluctuations of temperature.
E.g. for the HI 2 hysteresis, when the temperature is set
to 20 °C, the boiler will be switched on at 19.8 °C, and
switched off at 20.2 °C. For the HI 4 hysteresis, when
the temperature is set to 20 °C, the boiler will be switched on at 19.6 °C, and switched
off at 20.4 °C
The hysteresis change mode is signalled by flashing text “HI”. You can change hysteresis
settings with the buttons.
HI 2 – ±0,2°C (factory setting)
HI 4 – ±0,4°C
HI P – PWM operation mode (see chapter “PWM operation mode”).
Confirm the setting by pressing the . button. The regulator will proceed to change the
next parameter.
3.
OFFSET CHANGE
Offset allows for calibrating temperature indications within the tolerance of ±3°C.
E.g. the temperature regulator indicates that the room temperature is 23°C, whereas
a egular mercurial thermometer placed alongside indicates 24°C. Changing offset by
+1 degree makes the regulator indicate the same temperature as the mercurial one.
The offset change mode is signalled by flashing text OFFS.
You can set the desired value
within the range from
3.0 to 3.0 (factory setting is 0.0).
Confirm the setting by pressing the
button. The regu-
lator will resume normal mode of operation.
