LOCATION OF SENSORS
Correct positioning of the temperature sensors is essential to
proper indoor climate control.

To ensure correct functioning, use separate cable ducts for
the power cables (230 Vac) and for the non-polarised ter-
minals.
SM
(flow temperature sensor)Insert in the socket above the
flow pipe outlet from the boiler.
SB
(storage cylinder temperature sensor)Insert in the top
socket on the storage cylinder.
SR
(return temperature sensor)Insert in the socket to be
provided on the boiler return pipe.

To measure effective water return temperature and to control
the temperature stabilisation function, the socket for the return
temperature sensor must be positioned at a distance of 3 to 5
times the diameter of the water return pipe upstream from any
water fittings (condensate prevention pump or recirculation
pump).
