Description
When the pipe temperature is above the
space temperature and the hybrid control is
enabled, than the offset is suitable for
heating.
When the configured timer expires, the pipe
sensor reading is compared to the threshold
setting, if the pipe sensor reading is above
the threshold, it will generate water
temperature. No heating alarm will be
raised.
When the pipe temperature is below the
space temperature and the hybrid control is
enabled, than the offset is suitable for
cooling.
When the configured timer expires, the pipe
sensor reading is compared to the threshold
setting, if the pipe sensor reading is below
the threshold, it will generate water
temperature. No cooling alarm will be raised.
