Reverse / direct sequence follows heat –
cool state of controlle
OFF = control sequences activate based on demand and do not follow
heat – cool state of controller
ON = control sequence follow heat cool state. Reverse sequence will
only be active in heating mode, direct sequences in cooling mode
of controller.
ON, OFF OFF
1L 24
Delay for heat –
cool changeover in case above parameter is OFF
