Manual switch operation
The "ManualSwitchCondition" output of the module will provide the respective values of OFF(0), ON(1/ 2/ 4) or AUTO(3), depending on the wall module switch operations at the bypass button, the fan switch value and the setting of the extend period parameters. The following table shows the dependencies of the different switches and the output results:
To activate the bypass button one has to press it for a time longer or equal to the controllers cycle time.
The changes will occur in the second cycle after the controller has detected the bypass button change.
The bypass can take three positions:
By default the bypass button is in the auto position.
Pressing the bypass button, it's value will by set to the next value of the next value of the cycle - see next table.
e.g. pressing once the bypass will switch from auto to day.
