Controlled components
"Manual control" has higher priority than "Output override".
When the selected controlled component (output) is not 'AUTO' , the
ECL Comfort controller does not control the component in question
(pump or motorized control valve e.g.). Frost protection is not active.
The speed controlled pumps V1, V2 and V3 are controlled by 0 - 10 Volt
(0 - 100%) or PWM signals. Each of them can be set to AUTO or ON.
AUTO: Normal control (0 - 100%)
ON: The 0 - 10 Volt or PWM signal is set to the %-value, set below the
indication 'ON'.
When output override of a controlled component is active the symbol
' ! ' is shown to the right of the mode indicator in the enduser displays.
