TRC Sidekick systems are the ideal choice for wirelessly controlling irrigation systems with 12 or 24 stations. TRC Sidekick systems are completely portable, making them the ideal choice for commercial irrigation applications. Sidekick systems can be plugged into any 24 VAC irrigation controller outfitted with a Permanent Controller Connector (pigtail). The Sidekick FM provides single station access and is compatible with all DCI connector options. Sidekick systems are not compatible with permanent receiver cards.
