(a)
(a) There are actually two relays under parameter 5-40 (Relay 1 and Relay
2). When entering 5-40, the required setting on Relay 1 = Alarm (9) as
shown here but then you also need to scroll down to Relay 2 and confirm
that Relay 2 = Run (5). The relays are NOT interchangeable. Relay 1
must always be set to Alarm (9); Relay 2 must always be set to Run (5).
