The chronothermostat have two types of regulation:
On/off regulation
During on/off regulation the chronothermostat measures once a minute the environment
temperature and it carries out the regulation on the basis of the following logic:
heating mode
relay ON
relay OFF
SET-DIFF
Temperature
increasing
where SET represents the setpoint and DIFF the differential (useful to avoid continuous
switches on/switches off dangerous for the system in proximity to the reaching of the
setpoint).
Proportional regulation (heating only)
In heating mode, the on/off regulation is available and also the proportional regulation
which in some systems allows a more precise regulation to obtain a constant
temperature.
This regulation requires to specify two parameters:
• the band, which represents the temperature values within whom to perform the
proportional regulation. The band is centered on the setpoint and it can have values
between 0.5°C and 5°C; outside these values the heating will be
always on (if setpoint-band > environment temperature) or
always off (if setpoint + band < measured temperature).
• the regulation period which represents the duration of the regulation cycle
(activation time + deactivation time of heating) and it can have values of 10, 20 or
30 minutes.
