blockbypass_control

Information

Control function that sets the position of the bypass valve. The bypass valve can be opened constantly to allow a continous flow or it is controlled via a thermostat that opens the valve in case the temperature goes below the minimum setpoint (minus the bandwidth) and closes the valve once the temperature is above the minimum setpoint (plus the bandwidth).
