Extending the wireless range

A wireless signal gets weaker as it travels. Metal surfaces and metal in
constructions in particular can block the signal. The Danfoss Icon2™ Zigbee
repeater can help you improve your thermostats' connection. If the Icon2™
Master Controller is installed in an enclosure, you can add an external antenna.
