Integrated Controller Description The controller Type BS Plus is integrated in the insulation. It is designed for the application in various basic systems. This controller has 2 standard relay outputs and 4 sensor inputs for Pt1000 temperature sensors. The illuminated display with system monitoring (with blinking symbols for a clear allocation of the indicated data) permits a simple and clear appliance and function control. The controller is equipped with a storage temperature limit, an operation hours’ count, a thermostat function, a heat metering as well as (selectable) pipe collector functions. V-Bus.
UL/CSA certified. Supplied with 4 Pt1000 sensors (Ø6 mm, 1 with silicon wire) and 4 immersion sleeves (1 x 60 mm, 2 x 100 mm and 1 x 150 mm long).
