Remove fitting piece and replace with heat meter.
- do not forget gaskets.
- After mounting of heat meter remember to check and tighten
all threaded connections.
7.5 Mounting of outdoor temperature sensor
The outdoor temperature sensor is delivered separately and must be
mounted on site according to the enclosed illustrations.
The outdoor sensor is always to be mounted on the coldest side of
the property (normally the north side of the property).
The sensor must not be exposed to the morning sun, and should not
be mounted above windows, doors, air vents or other heat sources,
and not under balconies and roof eaves.
Mounting height approx. 2.5 m above ground.
Temperature range: -50 to 50° C
Electrical connections
Two wire non polarized (can be crossed)
Sensor cable: 2 x 0.4 - 1.5 mm²
Connect the cable ends to ECL controller in clamps 29 and 30.
7.6 Mounting of immersion sensor
The immersion sensor for accurate temperature measurement and
control in the cylinder is supplied separately and must be mounted
and connected to the controller on site.
Temperature range immersion sensor: 0 to 100 °C
Temperature range immersion pocket: 0 to 180 °C
2-wire cable (2 x 0.34 mm²) spliced is preassembled in the control-
ler.
1) Mount sensor pocket (separately delivered) in top or bottom of
cylinder.
2) Lay immersion sensor and cable from substation to cylinder and
mount immersion sensor in immersion pocket.
In case the length of the sensor cable is not long enough for your
property, it is recommendable to change the whole cable. The mini-
mum area for the cable is 0,4 mm² and max. length is 125 m.
For electrical connections please refer to enclosed Danfoss instruc-
tions for the ECL controller.
