TZ40 question


Hi All...

I have been looking at the TZ40 remote thermostat and have read all the docs. It says it handles up to three remote temp sensors, but the dpocs only show how to wire one of them, making no mention of how to wire more than one. Apparently the one sensor is wired to screw terminals on the WDU (wall display unit) itself. Does anyone know if it really does accept up to three and if so, how are they wired in?
