Help with digital timer wiring
I was hoping somebody with more knowledge than me could help with wiring a Frontier Timer for water heater. The heater has 3 green, black & Red color. The timer has 5 connector name,
1. Live
2. Neutral
3. (Dunno)
4. NC
5. No

I'm using 240V/16A here,
This is a link to the timer manual

Any Idea? Thanks for help.

Don't understand the problem---

I mean how to connect...

What I mean is the manufacture should have a wiring diagram i.e. -black & white(red) are live & neutral no= normally open nc= normally closed witch go to the limit switch (green) also check to see if they intend for an axillary switch

According to the wiring diagram in the rightmost pic.,
Terms 1 & 2 need 240v all the time.
Term 3 & 5 is normally open, 3 & 4 is normally closed.
Almost always you'd use 3 & 5 in series with the load and with the 240v power.
I suppose they supplied you with mating female connectors for these connector pins? Don't solder to these terminals unless they say you can.
