The controller has outdoor temperature dependant heating control of two radiator systems HS1and HS2 using
for each one or two control valves (HS1-CV1, HS1-CV2 and HS2-CV1, HS2-CV2). Also control of tap hot-water
using either one or two separate control circuts HW and THW or a single control circuit with two sequences
THW-CV1 and THW-CV2. Also two independent timer outputs TO1 and TO2 for controlling external functions
such as door locks, lighting etc.
