I purchased the Controller and six valve system. The manual does not describe what the lights on the power mean for the controller. Mine starts green, turns red, then turns to flashing between green and red and I can only see on the DTV + display that a UI device is being updated. It has been like this for 4 hours. Could it really take that long? The ethernet connection shows two green lights.

DTV+ actually works great, make sure your installer(plumber and electrician read the installation requirements before install. My outlet is a dedicated circuit and running our system with the 6 valve mod., water pressure is set @60psi running an overhead rain shower, 2 separate his/hers wall mounted shower, his/hers separate body sprayers and 1 hand held. Pressure is great and very responsive to controller inputs. If your system is not functioning correctly, your installer has done something wrong period!

Required this part and the DTV+ Interface when our DTV-I interface display failed after 15 years (control functions were still operable but display was nearly unreadable). Actual control of the DTV valve system now resides in this electronic module rather in the Interface. The PID algorithm to control temperature is improved over the DTV-I. At the end of a shower, this Module now shuts off the valves one by one rather than all at once (as did the DTV-I), providing almost no water hammer effect - nice! We are not using any other functions besides shower valve control.

This system is so disappointing coming from a company I’d admire greatly and whose products are throughout my entire home. The software and interface is so glitchy, constantly needing reset and is almost impossible to program. The Kohler Kinect app is not much better. Come on Herb, do better with this!!
