CW-3000 alarm connection

It looks like the alarm connection on the CW-3000 is a 3-pin DIN, but no idea how it signals alarm condition electrically. Does anyone here know?

Assume you saw the manual?


That’s a weird way to spec what appears to be a relay that closes for all types of alarms!

Decoder ring!

H1 = common
Common connected to H2 when:

  • Water stops
  • Temp higher than 60C
  • Pump Breakdown

  • Power outage

Common Connected to H3 when:
