Electrical box cover

ART•TEC Solar introduces an electrical box cover version of its PV-powered solar differential controller. The new model of the DTC-D solar differential temperature controller is available in an electric box cover version to fit in a 4x4 electric switch box. This will allow for attractive and unobtrusive installation in the living space of residences, while the wires can be run through conduit to the solar utility room. The DTC-D is specifically designed for solar or battery powered collector circulation pumps used in solar heating systems. The digital controller includes an internal battery back-up, which allows the controller to continue to display current temperatures and record max/min temperatures at night, or during overcast days. The controller’s backlight makes it easy to read in dark utility rooms. Features include: adjustable max temperature shut-off with optional over-temperature audible alarm; freeze alarm with optional freeze pumping for systems that operate from batteries; resettable max/min display of recent temperature extremes; and, the front panel controls allow easy changes to settings and manual override of pump to on, off, and auto modes.
