Product Description

The new BL-KR Battery Powered Bluetooth Controller from K-Rain means crawling around the valve box trying to program or troubleshoot a battery powered timer is a thing of the past.  The BL-KR timer puts full programming control in the palm of your hand through direct Bluetooth communication up to 32 feet away from the valve box.  With it's 100% waterproof and rugged construction, the BL-KR is ideal for isolated sites and power-restricted areas.  Add multiple controllers (up to 200 timers) and program quickly and easily from 1 free application.
