Essential Info

The INSTEON 220V / 240V 30 AMP Load Controller Normally Closed Relay (Dual-Band) lets you efficiently control the use of heavy duty appliances and take a step towards saving energy and cutting down on utility costs. It allows you to use other INSTEON devices to remotely control appliances, such as a hot water heater, that run on higher voltage, up to 30 Amps in a normally closed state. You can also use the local 'Set' button to toggle the attached load on and off. The relay comes with pre-configured wires and mounting hardware. There is no need to open the box for installation, simply identify the labeled wires and connect one set to your breaker panel and the other set to the high current appliance. This switch also uses INSTEON Dual-Band technology, which sends and receives INSTEON powerline and wireless radio frequency (RF) signals. This allows it to work as a phase bridge for superior signal reliability and as an access point for INSTEON RF and battery powered devices.

The INSTEON 220V / 240V 30 AMP Load Controller is also available as a Normally Open Relay, sold separately.

Required Accessories - Depending on your particular application, you will likely need:
4 to 6 large red wire nuts
3/4" conduit between the product and a near-by junction box
Suitable junction box for connection to existing wiring
Mounting screws

    James -- Florida   5/28/2014
    Owned 2 of the Load Controller Closed modules that were installed on our hot H2O heater. Both failed after a few months. Was not happy with C/S when several questions I submitted were never answered I was basically ignored which really surprised me after several years of great C/S from Smarthome. The open controller on our pool filter pump has operated flawlessly fro several years, but there is something abut the closed unit attached to the water heater that just does not work. Have decided not to purchase a 3rd unit for the water heater.
    chubby -- Deep South   5/7/2014
    It works. Does just what it is supposed to do, turn off the pool pumpo and turn it back on when I want. Easy install and all of that. 4 stars just because it costed more than I think it should have. I'd buy it again but would still complain about the price. One negative, it will not do dishes, housework, or mow the yard. Maybe the next revision will add this feature.
    HARRY -- palo alto, CA   10/4/2013
    New; not much experience yet. Seems to work as described. I use it to turn off hot water heater while we are away.
    STEVEN -- california, KY   9/23/2013
    Works very reliably. Would have given 5-stars if price was cheaper, and size was smaller. Given current cost of switch, it is hard to justify for energy savings.
    FRED -- canton, GA   7/19/2013
    return it, after not having any luck getting any devices to show up when I outside my home network, I didn't want to waste anymore money until I know this system works
    Grant -- Northern California   6/18/2013
    First one failed after 3 days. Second failed at 6 weeks. This is junk but I have little choice to remotely control my 220v pool filter pump. I'll try it again I guess.
    CHRISTOPHER -- cave creek, AZ   5/29/2013
    Did not work right out of the box. Got the last one they had. My guess is that it was already bad and returned. I returned it and am still, some 3 weeks later, waiting on the refund.
    Alex v -- Key Biscayne FL   5/21/2013
    Both relays that I ordered failed after one week. Smarthome would not send me a new one to exchange so I had to pay $100 X 4 2 installs and 2 re-installs WHen I spoke with support they would not send me a product as a replacement without paying. As a platinum customer Im quite disapointed and hope this is not reflective of the quality of this product.
    GEORGE -- bridgeton, NJ   4/9/2013
    Does not play well with others!
    jmw -- Florida   12/10/2012
    My main interest in installing this on my water heater was to turn off the WH when we were away on trips. But it also acts as an RF link for switches on the far side of the house. I have it hooked up to my ISY-99 and works fine, not problems at all, easy to install.
    JKD -- glendale, ca   7/10/2012
    I use this to control a pool pump. No neutral wire needed. Easy hook with the existing Old school timer that was already there. Just connected the wires and searched with the Isy 994i which found it instantly. It has working flawlessly for the past month.
    Don -- schuylkill haven, PA   6/26/2012
    The relay works reliably as advertised, however the dual-band function is not reliable.
    NIGEL -- medford, NJ   6/2/2012
    Original unit stopped working 2 weeks before 2 yr. warranty expired. Great service from Smarthome who replaced it with no problems.
    ANTHONY -- roseville, CA   1/5/2012
    Replaced with the NO version and now everything works great!
    JAMES -- clifton, VA   12/29/2011
    The unit installed without problem and linked immediately. I am still trying to check out the functionality and find the owner's manual a little cryptic about the meaning of the lights and why the unit shows off on the ISY99i console with the load shown as "on" on the unit panel. A little trial and error should let me work it out. This is great as I can turn the water heater on my second home on in advance of when I visit and turn it off if I forget to turn it off when I leave. Works great. I had a litte trouble stuffing the number 10 wiring required inside a 4x4 box but I probably left the tailes of the circuit a little longer than a professional electrician might have. it does make it easier to wire for an amateur but a larger box might be indicated if any such exists ( I am going to ook for one at the hardware store).
    MARK -- jacksonville beach, FL   8/6/2011
    have these in 2 of my homes.. love them...
    JOSEPH -- austin, TX   6/18/2011
    ROBERT -- star prairie, WI   1/16/2011
    Works as advertised. The instructions were easy to follow.
    ROBERT -- miami, FL   1/8/2011
    Works exactly as described. Easy to install and link up to my ISY-99 so I can run a program that limits the on and off time of my Hot Water heater. cons: A tad pricey perhaps?
    4 GUYS -- houston, TX   9/10/2010
    Love it. Just like everything Insteon makes it works perfectly.
