Well, a buddy was suppose to come help me wire my squirrel cage exhaust fan. It's a 240 V and I wired it and made sure it worked in the installation phase. I got this timer and installed it but I'm unsure how to wire it. I don't want to get it wrong. I understand a fair amount about wiring but reading the instructions isn't helpful. Here's some pic. Any help would be greatly appreciated. My grow room is at the stage where I need it.:wall:
I think it's the bottom right on that wiring diagram pic.

Sorry to provide no help what so ever to your question, an more than likely just provide annoyance, but why such a beefy timer?

The fan is 240v so less will make it run fucked up with 120v (I was told). It's the exhaust for the entire grow room. The timer can be set for 30 min. increments. No annoyance at all. thx for bumping it up I guess.

it was
make sure you set the dipswitches for the proper voltage.- 2&3 on for 220 volts.
your guess of the bottom right is correct if you want to power it from the same 220 volt feed.
to wire it for 220,you will have 2 seperate 110 legs,most likely red and black wires. the first 2 terminals are labeled timer,red goes to one,black to the other,add a jumper wire from the first terminal to the first NO terminal and a jumper from the second terminal to the second NO terminal.next run a red and black wire from the 2 com terminals (1 to each) and attach the fan.the timer case is plastic so it cant be grounded but be sure to ground the fan.
