30 minutes.
During the operating, at the beginning of the regulation period, the instrument
measures the environment temperature and it compares it with the programmed
setpoint; on the basis of this difference the activation time is calculated (and
consequently the deactivation time). The more the measured temperature is next to the
setpoint value – band, the more the activation time will be predominant in comparison
with the deactivation time; on the contrary, the more the measured temperature is next

comparison with the activation time).
Once regulation period is passed, the instrument compares again the environment
temperature with the setpoint and it updates the activation and deactivation times for
the new period.
The result of the proportional regulation is subordinated to the correct selection of the
parameters.
