Lowering mode (ECO)
In many areas of the building, it makes sense to heat to a lower temperature at certain times rather than permanently at the comfort temperature. By connecting
the input terminal Ø to 230 V, the temperature is reduced by 4 °C. This should be controlled by a central clock.
Controller adjustment
Depending on the heating system, the control behaviour can be adjusted. Pulse width modulated control (factory setting): The output is not permanently actuated, but for a time period (pulse width) that depends on the difference between target and actual temperature. This method brings the actual temperature gradually closer to the setpoint temperature.
Two-point control: The output remains switched on until the selected setpoint temperature has been exceeded by 0.5 °C. The output will not be switched on again
until the setpoint value is undercut by 0.5 °C. Since most heating systems respond very slowly, this type of control can entail temperature overshooting.
