Med ECO900 frostskyddsstyrenheten levereras ett 82 kΩ motstånd. I stället för motståndet kan tempera-
turgivaren ECOA904 installeras. I detta fall visas i displayens grundläge luftens temperatur utöver markens/
takrännans temperatur och fuktighet. Om nederbörd är att vänta på grund av att utetemperaturen sjunker
snabbt, kopplas värmen på för ca 1 timme vid temperaturer under +7 °C.
TEKNISK DATA
Temperaturgivaren är tillverkad av en kabel med ett isolerat NTC motstånd på ändan (bild 1).

ECOA904 TEMPERATURE SENSOR
ENG
INTRODUCTION
The ECOA904 is an air temperature sensor which can be connected to the ECO900 frost protection control
unit.
In rainwater systems the sensor is used to measure the temperature of a gutter.
The sensor can also be used as an accessory both in outdoor areas and rainwater systems. In this case the
sensor is connected instead of the 82 kΩ resistor that is supplied with the ECO900 frost protection control
unit.
ECO900 frost protection control unit is available as versions 1 and 2.

INSTALLATION OF SENSOR
The air temperature sensor ECOA904 is installed with a cable clamp (not supplied with the equipment)
either outside the gutter or on the wall nearby (figure 2). Ensure that the sensor is protected from direct
sunlight. The sensor must not be fitted in areas where heat accumulation can occur, i.e. above windows,
near lights or a chimney.
The connection cable can be extended to 50 meters by using a 1,5 mm² cable. It is recommended to use a
cable with numbered leads for the extension as it is very helpful for example when trying to locate faults
during a malfunction.
Figure 2 shows the installation of the snow and ice sensor ECO903 and the air temperature sensor ECOA904:
