Climatic Controllers for central heating
400 line controllers are electronic type with integrated circuit with two-relay floating output signal.
Signals are activated as proportional impulses, whose duration is proportional to the difference of the controlled variable tempera-
ture with respect to the set value.
These controllers are equipped with two sensing elements (supply sensor and outside sensor) and they control hot water supply
temperature in function of outdoor temperature value, according to a preset slope.
Suitable field devices are globe valves motorised by MVB2x and MVH2x actuators or shoe valves motorised by MDB24-44+AM72.
