It must not be exposed to morning sunlight, and must not be po-
sitioned above windows, doors, ventilation ducts, balconies under
overhanging roof sections, or close to any other heat source.
Installation height: approx. 2.5 m above ground level.
Temperature range: -50 to 50° C.
Electrical connection
The cables can be connected to the sensor in any order.
Connection cable: 2 x 0.4 - 1.5 mm²
The cable ends are connected to the ECL 310 controller in common
ground terminal and in terminal 29.
S 22 med electronic control of both circuits (App. A266)
From factory the controller is electrically wired to sensors, pump and
actuators according to the diagram to the right.
Mounting of sensor for DHW (ESMU)
Sensor pocket and sensor are factory-mounted in the unit and elec-
trically wired to the controller in common ground terminal and in
terminal 26.
Other sensors
Other supply and return flow sensors are also mounted and electrically
wired to the controller from factory.
Mounting of pumps
The circulation pump P1 is electrically wired to the controller in
terminal N and terminal 11.
The P2 for the heating circuit is electrically wired to the controller
in terminal N and terminal 12.
