There are cheaper ones available.

Make sure your controler and coil (on the contactor) have the same voltage. I screwed up and and blew my coil.

im using this contactor

C25BNF240A

the controller says 20 - 260vAC

so will that combo work?

and where are cheaper ones?

Thanks

That contactor has a 120v coil.

This is the controler I use.

When you order, you will have to buy the unit that matches your coil on your contactor.

the controller says 20 - 260vAC, so doesnt that mean it does 120?

I don't know...

You'll be better off using a SSR (Solid State Relay) rather than a contactor for heater loads. The SSR will switch on at the zero cross over and ramp on the cycle.

Your contactor has a 120vac relay coil. To use it, you'll need to use the J2 relay in the controller. DO NOT connect it to the SSR output terminals of the controller. The controller will RUN on 20-260vac and 120vac falls in that range to the best of my math. What is the voltage of your heater coil(s)?
