Asked by: Steve
Finding an appropriate replacement for your current transfer switch necessitates taking many factors into consideration. These factors include, but are not limited to, your desired loads, the configuration of your home and the size of generator that you are currently utilizing. If you are looking to replace your current switch and a replacement is unavailable, we would recommend contacting a certified dealer in your local area. Moreover, a Smart Switch has a load shed module that will handle up to six larger loads with the use of the pre-designated contacts, two of which are designated for air conditioner units. The (2) air conditioner contacts will be connected via the 24v low voltage thermostat wires for your air conditioner. These (2) contacts automatically come ready to use in the switch. If additional load management/shedding is required, we offer PMM modules as individual accessories. Up to 4 PMM modules can be used with each switch to monitor and shed additional large motor loads like your hot water heater, well pump, etc. When the generator starts up, these 6 non-priority loads will remain off for 5 minutes. After 5 minutes, these non-priority loads will stagger start based on priority to ensure the most efficient generator use. First AC contact 1 and PMM Priority 1, thirty seconds later it will start AC2 and P2, then P3, then P4. This eliminates the huge surge of these large motors all at the same time, which allows a smaller generator to power more by running more efficiently. The load shedding module will monitor the generator while it is operating to ensure it is not overloaded. If the generator becomes overloaded, (if the engine frequency drops) the load shed module will shed all of the connected loads, reducing the demand on the generator. The load shed module will then begin a five minute timer, after which, each load will be brought on in priority order. Typically via 30 second stagger start. Each time the generator becomes overloaded, the load shed module will intervene to prevent the unit from shutting down. If you have any other product-related inquiries, please do not hesitate to contact us directly at 888-GENERAC (436-3722).

I have a Kohler generator 45RZG. will the the Generac switch RTSY200A3 work with my unit.

Asked by: Anonymous
The 200 amp Smart Switch, model RTSY200A3, is designed to be paired with a Generac generator, as the generator’s control panel provides the function signals for the transfer switch. Compatibility between the RTSY200A3 and another brand’s generator cannot be guaranteed, as the transfer switches are tested for compatibility with only Generac products.
