In order for MyALARM2-1 and MyALARM2-2 to provide the correct temperature value with their
internal sensor, follow the following points (otherwise for MyALARM2-3 it is necessary to move
the sensor as much as possible from MYALARM2):
1) Turn on MyALARM2 power via the 12V terminal (thus not USB or battery
powered). Do not power external sensors via MyALARM2 12V terminals or
current outputs.
2) Move the sensor as much as possible from MYALARM2. An external sensor to be
connected to the terminals is available as an option.
3) 3 hours from installation, manually calibrate the temperature reading adding an
offset (positive or negative) using SMS command:
SET HVAC.OFFSET
For example with:
SET HVAC.OFFSET -1
Current temperature is lowered by 1°C.
Temperature must be calibrated only 3 hours after turning on MyALARM2 in the reading room.
