On a different note, I have discovered that I am exceeding the maximum power of the RWS17 on a couple of circuits and have purchased Instineon 1000w switches to replace them. I have just read that these will not work with the RWS19 companions that I have also installed. Is there an alternative that will work? All the wirning is complete and I would hate to have to change the companions as well.
Be advised, the Insteon Dimmers(?) will require a ground (return) for proper operation. This will normally be present in a three way circuit, but may not be run to both boxes. The RWS19 cannot be used as a companion in a three way circuit. The Insteon switches are 2 way X10 compatible - they will transmit on/off x10 commands when operated. This gives you some interesting options.

- 1.) For a wired 3 way installation you could use 2 of the 1000W Insteon switches (expensive) or you could pair a single 1000W switch with a 600W Icon switch (less expensive). If you use a lower power Icon switch as the companion you MUST make certain that the 1000W switch is controlling the load.
- 2.) Since the Insteon switches are X10 2-way, you could created a "vitual 3-way circuit". For this configuration you would rewire the 1000W switch directly to the load. The second switch (Insteon or other 2-way) is wired from power to common with the output capped and can be placed anywhere in the house. The switches are then programmed to the same house and unit codes. When the Virtual switch is activated it will transmit is X10 house and unit code + on/off and the hardwired switch will respond.
- 3.) Dispense with the Insteon switches and get a Leviton (HCM10??) 1000W switch + slave. These can be wired in a three way circuit and the common lead connection is provided (for noise immunity) but optional.
I have all of the above configurations in my house.
