temperature indication will blink.
6.4 External temperature sensor
Instead of the unit built-in sensor, it is possible to use an ex-
ternal temperature sensor with radio transmitter (MDTEMP).
Once installed and learnt, the wireless temperature sensor
will replace the built-in sensor for all functions.
By default, the temperature detected by the built-in sensor
is still displayed with smaller numbers next to the external
sensor temperature.
The two indications can be inverted and the display of the
built-in temperature detector can be disabled.
Once the detector has been learnt, its supervision is auto-
matically enabled with 12-hour intervals (fixed value).
If the detector does not communicate with the unit for 12
hours the message
???°
will start blinking on the display; if
the detector controls a boiler, the boiler will be switched off.
The temperature detector sends data any 15 minutes or
when a temperature value changes; the minimum interval
between data transmissions is 3 minutes.
The external detector can be calibrated only through the
built-in keypad.
Remote interrogation commands are available to notify the
two temperature values via SMS.

Example
For example, referring to above image:
• in time interval 6-7 level 2 is applied (small square on row
2)
• in time interval 9-10 level 1 is applied (small square on
row 1)
• in time interval 11pm-12am level 3 is applied (no small
squares)
