Multi-configurable controller with communication capability, and with digital user surface, for controlling heat-ing and drinking water supply. Particularly suitable for use with one or two converter control loops in local- and district-heating networks. Weather-compensating control of the secondary flow temperature and limita-tion of the primary return temperature. Room-temperature connection in conjunction with a room-temperature sensor or remote-control unit. Analogue inputs for Ni1000 temperature sensor. Outside tem-perature is transmitted via device bus. Pulse input for quantity or flow counter and limiter. Outputs for motor-ised drive(s) fitted to valves or control valves (3-pt.), pumps (on/off) and for configurable functions.
