      INSTALLATION

      Before installing, make sure the load does not exceed 960W for incandescent lights, 150W for LED's, 3A for fans and motors, or 10A for resistive load. Check your wiring first to confirm that you have all the following wires present in your gang box: load (most often black), line (most often black), neutral (most often white), and ground (most often green).

      If you are not comfortable identifying the wiring and following the instructions, please hire a licensed electrician.

      Here are some helpful wiring tips:

        • Make sure the gang box you are about to install the switch has a neutral wire available - you will not be able to get the ZEN51 relay to work without a neutral wire. If neutral is not available, you'll need to install the ZEN51 at the light fixture.
        • Unlike regular mechanical switches, Z-Wave switches require all of the wires to be connected exactly as indicated - line and load wires can never be swapped as it sometimes happens to the most experienced electricians.

      How to include the Dry Contact Relay to your smart home network?
      1. Bring your Z-Wave gateway hub or controller as close to the switch as possible
      2. Put your Z-Wave controller in inclusion/pairing mode
      3. Click the Z-Wave button on the relay 3 times quickly to finalize the inclusion process
      4. A new on/off switch should appear on your controller's device list

      💜
      my 6’4” husband wore this to our wedding. it looked amazing on him 💜 everything fit pretty good except for the jacket part; that was a little big. it may fit someone who weighs a little more but my husband weighs about 165lbs. we had to tailor it a little bit. other than that, very beautiful suit.

      Mans XXL Light Baby Blue Linen Suit 6'5" 225 lbs
      Mans XXL Light Baby Blue Linen Suit 6'5" 225 lbs "This suit fit me perfectly. I was unsure of fit initially so I looked at measurements carefully and selected -true to my size- On suits that arrived a size too big I used a strategy found on Google to shrink my suit. On the wash setting, set it to hottest water setting and tumble/time setting. On the dryer set it to longest hottest heat setting and two things will happen, it will take out wrinkles and be a perfect fit!

      4.5 Stars.. Comfy, but Really Check the Size Charts
      I love the material of this suit. Very comfy fabric. Out of the box, it was WAY less wrinkled than I thought it would be. The pics I took are of the suit are straight out of the packaging. When it comes to the suit itself, I really have nothing but complements. I will note a few items on the sizing: I am 6'3", 270, and I got the 3XL. The size chart says it goes to 260lb, and I think it is right, but with a caveat... Here's why: Pants: The pants actually fit me great. There is a comfort waistband, but I don't even really need it. I generally wear a 40" jean; 38" when they go to a loose fit.. The inseam is great as well. I am either a 32" or 34", but most 32" inseams are a bit short... Jacket. I tend to wear a XXLT or a 52L from a suit shop. The shoulders of the jacket fit fine. It feels OK through the arms and chest, but it is probably 1/2 - 1" away from a comfortable ability to button the jacket at my "gut". Thus my comment about sizing. I am a bit surprised that the pants fit so well through the waist but the jacket does not fit as ideally. Still - I think I am only a few pounds away from a good fit. So I kept the 5 star review with the note as the size chart does call it out... Being so descriptive here for your benefit.
