When configuring the relays on a HyperStat, the operation of the fan is determined by the fan setting.
In the example below, Relay 3 is set to 'Fan Enable'. 'Fan Enable' tells the fan to run constantly during occupied hours. It will also run the fan during a heat or cool call during unoccupied.
Setting a HyperStat to 'Fan Enable' gives you the options to set the Fan Mode to either 'Off' or 'Auto'.
Alternatively, you can use the drop down to set the control to 'Fan Low Speed'.
Using 'Fan Low Speed' will give you additional options, such as both 'Off', and 'Auto', as well as 'Fan Low Current Occupied Period', 'Fan Low Occupied Period', and 'Fan Low All Times'.
