After inserting the new batteries, the battery charge is checked. During the
check, the green LED lights up for 2 seconds, provided the batteries are
charged sufficiently.
After the check, the radiator control actuator checks its settings as master or
slave. If set as master, the red and green LED blinks 3 times; if set as slave,
the LED remains dark. The device then automatically calibrates. Afterwards,
the device assumes Normal operation.
