Description of the function
Monitoring starts as soon as the maximum output level is produced in heating mode (see ex-
ample) or as soon as the minimum output level is produced in cooling mode. Starting from this
point, the actual value must leave the monitoring band – the range around the current actual
value at the start of monitoring – within the response time. If it does not, an alarm is triggered.
On leaving the monitoring band, the actual value at the time is used as a reference value for a
new monitoring band. The response time starts over.
Monitoring ends as soon as the maximum or minimum output level is no longer produced.
