  • What's Included
  • 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

    Insteon is a powerful home-control networking technology. Insteon messages are transmitted throughout your home both wirelessly and through the home's existing wiring. All Insteon messages are confirmed and repeated by Insteon devices in the network, contributing to the outstanding reliability and performance of Insteon products.

    dependable only for a while Review by Pete
    dependable only for a while

    These 220V switches have controlled my hot water heater and my pool pump for years. They worked perfectly for a while, but they quit working and had to be replaced several times. This website says they are not available now. I really need then for my hot water heater and my pool pump. Will they eventually be available?

    Works poorly with Alexa. Review by Douglas
    Works poorly with Alexa.

    Works poorly with Alexa. Bought 2 of these to control two AC's via 8 button switch. Everything worked initially. However, the insteon hub would not send these devices to Alexa, so I used my ISY hub to do that. For a while that worked. Now the buttons have no effect whatsoever on the units. Alexa can reach them say one time out of 5 tries (the other 50 devices on the network work on the first command). Also when I opened them up, it said "Resistive loads only", which AC's are not. Nowhere was that stated in the specs. Bottom line, after spending $200 on these, threw them both out and am using inline on/off switches wired to a Din contactor (basically made my own unit for less) that is 100% reliable.

    I am sorry to hear you are experiencing issues. Please note that these are listed as not being compatible with the Alexa skill. You can find a complete list of compatible devices at the link below.

    While the product page does not reference Resistive loads, it is referenced on page two of the owners manual which is linked to on the product page. I will forward this concern along to the team to see if they can add it to the specifications tab as well.

    Pool Pump Automated. Check! Review by Vann
    Pool Pump Automated. Check!

    I have been considering this switch for some time now. I have installed it to automate my pool pump. Installation was easy and it works flawlessly. I have combined it with an automation routine in Houselinc.
    Should have done it a long time ago it is great.

    Problems with reactive loads Review by michael
    Problems with reactive loads

    The specs don't differentiate between resistive and reactive loads. I put a N/O unit on a water heater and it has worked fine for years. I put a N/C unit on a well pump and it is constantly sending on/off messages back to my controller. I think the reactive pump load caused power fluctuations that affect the insteon control because the false messages occur when the pump turns on. I'll try to add some capacitance to the circuit and see if that helps.

    Great pump controller Review by PETER
    Great pump controller

    I installed 2 of these for my pool and spa pumps, along with leak detectors, programmed through my ISY. They seem bullet-proof, and already saved me some grief when we had a leak in the equipment room while we were away, and the auto shut down program prevented a serious flood. Well worth the money, especially at this price!

    Does the job but not reliable Review by michael
    Does the job but not reliable

    This device provides high current load control for my water heater, but I have had two fail in 5 years. Completely fail. I'm not sure what the problem is, but I suspect that relay noise affects the circuitry because they tend to get flakey every once in a while and are unreachable.

    I think a better approach is to use an Insteon micro controller driving a 220V relay. You can size the relay to get the load support you want and the micro controllers have never given me a problem. I use this technique to control heating coils attached to rain gutters for ice melting.

    2 years working Great Review by cjg
    2 years working Great

    Had a problem with the first unit where it would not stay connected. Got the new unit and its now 2 years no problems. It controls a hot water heater in a vacation home such that I can turn the water heater off when nobody is there.

    Review of 2477sa2 Review by James
    Review of 2477sa2

    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.

    Review of 2477sa2

    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.

    New; not much experience yet. Seems to work as described. I use it to turn off hot water heater while we are away.
