Mode 0 alarm is off,
!
Mode 1 alarm comes on when the current temperature exceeds the
first alarm threshold,
!
Mode 2 alarm comes on when the current temperature drops below
the first alarm threshold,
!
Mode 3 alarm comes on when the current temperature exceeds the
first alarm threshold, and at the same time is lower than the second
alarm threshold.
!
Mode 4 alarm comes on when the current temperature drops below
the first alarm threshold or exceeds the second alarm threshold.
!
Mode 5 alarm comes on when the current temperature exceeds the
second alarm threshold, and comes off when temperature drops below
the first alarm threshold (hysteresis). If a power outage appears in this
mode the meter memorises states of relays and the last temperature,
This makes possible correct alarm operation after re-powering.
Alarm modes are presented in a graphical form on page 22.
