relay module is missing. Wait no more than 2 minutes for automatic
recognition, or reset the device.
• TIMED OPERATION (
symbol).
At the end of the set time in hours, the thermostat returns to oper-
ating at the Comfort temperature level.
• OFF.
You may choose between Off (OFF symbol) and Timed off. In the
latter instance, the remaining time in hours until restarting is dis-
played; this time may be changed using the
button and con-
firmed with OK button.
• HYSTERESIS.
Adjusts the value of the temperature hysteresis parameter.
Hysteresis is the amount by which the ambient temperature can
deviate from the set-point before the system is switched on and
off. By adapting the hysteresis parameter to the type of system, it
is possible to prevent repeated switch-on and switch-off around
the set-point value; systems with high inertia (for example with cast
iron radiators) require a low hysteresis value, whereas systems with
low inertia (for example fan-convectors) require a higher value.
Example.
With a temperature set-point of 20 °C and a hysteresis of 0.3 °C,
the system will switch on when the ambient temperature drops
below 19.7 °C, and will switch off when the ambient temperature
reaches 20.3 °C.
• TEMPERATURE SCALE.
Used for setting the units of measurement for temperature, choos-
ing between degrees Celsius and degrees Fahrenheit.
• RESET.
Simultaneously pressing the
, and OK buttons, the ther-
mostat resets and returns to the following default values:
- Comfort temperature: 20 °C
- reduced temperature: 15 °C
- Off timer: 12h
- reduced temperature timer: 12 h
- antifreeze: 5 °C.
- thermal differential: 0,2 °C.
