If you press the middle button (value) the value of this menu item, shown in the bottom line, is advanced. If you press...
Menu items: application: range: ground, roof default value: ground the application (gutter or ground)is selected with this setting. The application selected will be retained when you revert to the default program. Range: range: –5 … –20 °c (23 …–4 °f), off default value: –10 °c lower temperature lim...
Operation: range: automatic, permanent default value: automatic with this function, you can switch the heating on continuously, irrespective of the set temperatures and humidity. The heating remains switched on during an alarm. Sensor heater: range: auto, on default value: on in automatic mode the s...
Alarm messages: in the event of an alarm, the display starts flashing at one second intervals. The alarm relay closing contact (terminals 5 and 6) closes. The word “alarm” appears on the top line. At the same time, the cause of the alarm is displayed on the bottom line. This alarm display appears in...
Operating: if the temperature set in the ice detector falls below the predetermined value and if the set humidity is exceeded at the same time, the heating will be switched on by means of the heater relay and the terminals 8 and 9 (see connection diagram). If one of these conditions is not fulfilled...
Ice and snow sensor (5-core)esf 524 001 or esf 524 011 the sensor is equipped with an ntc resistor to measure the sensor surface temperature, a heating coil and two metal rings as humidity sensors. Nominal voltage: 8v- power consumption: approx. 7w surface temperature: approx. 4 °c (39.2 °f) connect...
Combined temperature and moisture sensor tff 524 002 or tff 524 012 (4 core) the combined sensor is equipped with an ntc resistor for ground temperature measurement and two metal rings are installed as moisture sensors. This sensor is, however, not independently heated. Connecting lead: 4 x 0.5 mm; ...
Sensor assembly the ice and snow sensor esf 524 001 (5 core) is assembled as follows. The snow and ice sensor is mounted outside the heated area (see figs. 2 and 3 on page 16). The sensor must be assembled so that it is directly exposed to the weather conditions (snow, rain, melt water (see figs. 4 ...
The combined temperature and moisture sensors tff 524 002 (4 core) are assembled as follows. The combined sensor is installed inside the heated area (see figs. 2 and 3 on page 16) as it must monitor the ground temperature of the heated surface at all times (whether it is switched on or it is switche...
Sensor assembly in fag 524 111 sensor housing determining where to fit the sensor/sensor housing is extremely important to ensure that the system works as well as it can. The sensor must be fitted where it first becomes smooth or where it is smooth for the longest length. The esf 524 001/011 sensor ...
Installation of the sensor in the fag 524 111 sensor housing a protective metal pipe running up to the sensor housing should be provided at the construction site for the connection cable. If the sensor is to be run over an appropriate underlay (foundation or base plate) must be provided so that the ...

Assembly: the esf 524 003 (5 core)ice and snow sensor is assembled as follows. Where possible, assemble the ice and snow sensor near to the downpipe or waste pipe (lowest point) of the gutter between the heating cables (do not let them come into contact with one another). The sensor is to be fitted ...
