Example 2: Master with Slave Units
The remote interface feature oers the opon of lower cost 2-way or mul-way switching by
connecng up to ve slave switches to a single TDS3 master unit. Unlike parallel wiring (Example 1),
this method retains full control from any switch locaon, and does not increase the minimum load
requirement. The master unit controls the ming cycle and switches the load, and any of the slave
switches will funcon idencally to that on the master unit.
Each slave switch may be either a TDS-S slave unit (which provides an idencal touchsensive
buon) or an ordinary normally-open mechanical switch (such as a pushbuon or retracve rocker).
Referring to the steps under Installaon, connect as follows.
• TDS-S: Use 3-core mains-rated cable and connect as shown below. Figure 5 illustrates a typical
wiring example using two TDS-S slave units; Figure 6 represents the same conguraon as
applied to a typical ceiling rose lighng circuit.
• Other switches: Use 2-core mains-rated cable and connect to the R+ and R- terminals only
(polarity does not maer); do not use the V+ terminal.

The slave switch connecons are referenced to the mains supply of the unit, and are therefore not
safe to touch when the unit is powered. All switches and cables must be rated for mains voltages.
