The regulation band represents the temperature interval, centered on the setpoint,
in which the proportional regulation is checked.
Half the desired regulation band is set in the device.
The range for this parameter is 0.5 ÷ 5.0°C with 0.1°C resolution
The regulation period represents the duration of the regulation cycle (activation
period + deactivation period)
The value of this parameter is selectable between 10', 20' and 30'
Choose the regulation period value as follows:
- 10' for low thermal inertia systems
- 20' for medium thermal inertia systems
- 30' for high thermal inertia systems
Choose the regulation band value as follows:
- broad band (5°C) for systems with high thermal gradient
- narrow band (0.5°C) for systems with low thermal gradient
• tP regulation
Note. This regulation should be used only if you are controlling a valve for
ThermoPro RF radiators.
This type of regulation allows you to make the ThermoPro RF valve work "by the
opening modulation". In this way, the valve opens in proportional mode according
to the difference between the set temperature (setpoint) and the detected
temperature.
Selecting one of the other regulation types, the valve will not work in proportional
mode, but it will be completely open or completely closed according to the
difference between the set temperature and the detected temperature.
