iO-W1-100 | WireONE Auxiliary Switch | iO HVAC Controls (OBSOLETE)

WireONE Auxiliary Switch

Today’s programmable and communicating thermostats often need a “common wire” to power the radio modules and other electronics. On average, 30% of all homes do not have a common wire at the thermostat. The iO-W1-100 uses multiplexing technology to allow an additional signal to be passed through the common wire.

Features and Benefits:

•  Reduces installation time and cost 
• Eliminates the need to run additional wiring 
• Allows a single signal (W, Y or G) to be multiplexed over a common wire
•  Supports single and dual transformer installations 
• Supports both heat pump and conventional systems 
• Provides short circuit protection through a self-resetting thermal fuse 
• Includes a signal coupler and 5 splice wire caps 
• Compatible with virtually all major thermostat brands
