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 .
