WARNING:
This electronic device can be fitted independently for the fully automatic electric
heating of open spaces, garage drives, stairs, ramps, flat roofs and gutters.
The device must only be installed in the housing by a qualified electrician in
accordance with the connection diagram. Pay strict attention to the VDE’s and the
local electricity supply company’s safety instructions. The device is intended for
installation in control cabinets or distributors To achieve protection class II
appropriate installation measures must be taken. The device complies with DIN EN
60730 and works in accordance with operating mode 1C.
Proper operation is only possible if the system is already put into operation before
there is frost or snow and not only when the open spaces or gutters to be heated are
already covered with snow or ice. It is recommended that the system is left on during
the entire heating period!
Note!
The system can only work properly if the thermal output of the space to be heated has
been calculated properly or adapted to local conditions. Please contact your system
installer.

Instructions:
The ice detector is installed for the fully automatic electric heating of open spaces, garage
drives, stairs, ramps, flat roofs and gutters. Unlike manually controlled (touchdependent) or thermostatically controlled (only temperature dependent) systems, the
heating will only be switched on if there is a danger of slippery conditions, i.e. snow, ice or
sleet and will, naturally, be switched off after thawing. This ensures energy savings of up
to 80% compared with thermostatically controlled systems.

Table 2: Alarm messages
The settings of the menu items can be changed during an alarm; The display carries on
flashing at one-second intervals to display the alarm.
The alarm statuses are still displayed up to approximately 5 secs. after fault clearance. When
sensor heating is switched on (sensor temperature <4°C) it is permanently monitored for
short circuits. It is switched off. for 1 second every 4 minutes to test it for a break. If sensor
heating is switched off (sensor temperature > 4°C) it is permanently monitored for a failure.
It is switched off for 1 second every 4 minutes to test it for short circuits.

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 the heating will remain off.
The open space or the gutter heating remains switched on until the set humidity falls
below a predetermined value or the set temperature is exceeded,
If the post purge heating function is needed (generally only if there is still snow remaining
on the sides after the heating has been switched off) you can recall this function by
pressing the MENU-button and the desired time set. The post purge heating process takes
over before the EM 524 89 switches the heating off again, as the temperature or the
humidity no longer meet the conditions to be switched on.
The lower temperature limit is set (–5°C…–20 °C) in the RANGE menu item
The upper temperature limit is fixed at +6°C. Outside this limit the heating can only be
switched on using the CONTINUOUS HEAT menu item.
The surface of the ice and snow sensors ESF 524 001/011 and ESD 524 003 is heated
intermittently to, for example, thaw snow and ice. Water is formed that the sensor will
identify as humidity.
The BASE TEMP menu item has a setting range of –15°C....–1°C and OFF. This base
temperature is, for example, –5 °C and has to keep the surface to be heated from falling
below the preset value of –5 °C. If the temperature falls below this preset value, the
heating will be switched on until this temperature is exceeded. The lower temperature
limit has priority over the base temperature. This means that if the base temperature is
set lower than the limit temperature, the base temperature cannot be maintained as the
ice detector will be already be in “stand-by” mode.
Please take note: The higher the set temperature, the higher the heating costs will be.
Design
The equipment consists of the central control unit EM 524 89, the separate ice and snow
sensor ESF 524 001/011 and the combined temperature and moisture sensor
TFF 524 002/012 for open space heating e.g. the ice and snow sensor ESD 524 003 and the
temperature sensor TFD 524 004 for gutter heating. Additionally, the TFD 524 004 sensor
can be connected as an air temperature sensor and to detect when there is a drop in
temperature.
Attention
The sensors are operated with safety extra low voltage. The appropriate regulations
for safety extra low voltage are to be adhered to. In order to ensure trouble-free
operation, we recommend that the sensor cables are laid at a sufficient distance
from the load circuit and power supply lines.

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 and 5 on p. 17).
The sensor’s steel plate is set in the ground during the construction phase and the
wooden mould is placed on top. The steel plate must be used to fix the sensor to
guarantee the impermeability of the fixing hole. If the steel plate cannot be inserted due
to constructional reasons, then a washer with a nut must be used. This is the only way in
which the impermeability (press fit) in the bolt hole can be guaranteed. Note the red
information tag!
A protective metal pipe must be installed flush to the wooden block for the connection
lead. Seal the pipe ends to avoid any foreign bodies (tar, concrete, etc) clogging the
protective tube.
After applying the top road surface, the wooden mould is removed and the sensor is fixed
on the steel plate using the M 6 x 35 screw.
Ensure that the sensor cannot, for example, be covered by snow being cleared outside
the heated area. Any foreign bodies or materials can impair the operation of the sensor.
Any existing gaps must be filled with, for example, silicone, tar, mortar or depending on
the composition of the surface. Max. casting temperature 80 °C (179 °F).
The sensor’s connection lead, default length 15 m (50 ft.), can, in accordance with VDE
0100, be extended up to a length of 50 m (164 ft.). with a cross section of 1.5mm2 (20
gauge)
It is recommended that a numbered cable is used for the extension. This is very helpful,
for example, when trying to locate faults during a malfunction.
12
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 switched off).
Heating cables must bypass the combined sensor with a minimum distance of 2.5 cm (1“)
(see fig. 6 on page 17).
Ensure that the heating cables running parallel to one another do not touch. The combined
sensor must be fitted so that it is directly exposed to the weather conditions (snow, rain,
melt water, etc) (see figs. 4 and 5 on p.17).
The combined sensor’s steel plate is embedded in the ground during the construction
phase and the wooden mould is placed on top The steel plate must used to fix the sensor
to guarantee the impermeability of the fixing hole. If the steel plate cannot be inserted
due to constructional reasons, then a washer with a nut must be used. Only in this way can
the impermeability (press fit) in the bolt hole be guaranteed. Note the red information
tag!
A protective metal pipe must be installed flush to the wooden block for the connection
lead. Seal the pipe ends to avoid any foreign bodies (tar, concrete, etc) clogging the
protective tube.
After the applying the top road surface, the wooden block is removed and the sensor is
fixed onto the steel plate using a M 6 x 35 screw.
Ensure that the combined sensor is fitted so that it is, for example, not covered by snow
being cleared outside the heated area and that no vehicles can drive over the combined
sensor ( for example, when entering or leaving a garage). Any foreign bodies or materials
can impair the operation of the combined sensor.
Any existing gaps must be filled with, for example, silicone, tar, mortar or depending on
the composition of the surface. Max. casting temperature 80 °C (179 °F).
The combined sensor’s connection lead, default length 15 m (50 ft.), can, in accordance
with VDE 0100, be extended up to a length of 50 m 164 ft.). with a cross section of
1.5 mm2 (20 gauge).
It is recommended that a numbered cable is used for the extension. This is very helpful,
for example, when trying to locate faults during a malfunction!
13
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 (5-core connection cable) is fitted outside the heated
surface.
The TFF 524 002/012 sensor 4 core connection cable) is fitted inside the heated surface.
Installation of the sensor in the FAG 524 111 sensor housing
Only the two sensor types ESF 011 and TFF 524 012 are suitable for installation in
the sensor housing.
With both of these sensors the connecting cable does not come out from the side but
from underneath.

14
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 sensor housing cannot be pushed into the soft ground.
Ensure that there is sufficient cable in the lower part of the sensor housing so that, when
necessary, the sensor can easily be withdrawn from the housing.
Sensor housing in a concrete road surface
The sensor housing can be inserted in during the cementing process and the sensor
inserted later.
Suitable measures must be taken to ensure that the concrete does not get into the
housing.
The housing is to be installed so that the sensor surface is level with the ground surface.
The sensor must not, under any circumstances, project from the ground surface. A level,
horizontal installation is fundamental even with a sloping surface.

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 so that it lies in the flow direction of
the discharged water with the two metal pipes pointing upwards. The water running off is
led to the sensor surface by the extruded blower. The blower can be cut to fit the existing
conditions of the gutter
The sensor’s connection lead, (default length 4 m, 13 ft.), can, in accordance with VDE
0100, be extended up to a length of 50 m (164 ft.). with a cross section of 1.5mm2 (20 gauge)
It is recommended that a numbered cable is used when extending the connection lead.
This is helpful when trying to locate faults during a malfunction.
The temperature sensor ESF 524 004 (2 core) is fitted as follows.
The temperature sensor can be fitted outside either on the gutter or near the gutter but
whichever one you choose, care must be taken to ensure that the sensor is protected
from direct sunlight. The sensor must not be fitted above windows or in areas where heat
accumulation can occur (roof sills, chimney, attic windows and the like).
The sensor’s connection lead, (default length 4 m, 13 ft.), can, in accordance with the VDE
0100, be extended up to a length of 50 m (164 ft.). with a cross section of 1.5mm2 (20 gauge).
It is recommended that a numbered cable is used when extending the connection lead.
This is helpful when locating faults during a malfunction.

Setting desired values
Range setting
The RANGE menu item is called up with the MENU button and the lowest temperature
limit is set with the VALUE button.
This temperature value specifies the lower operating temperature limit.
The upper working temperature is fixed at +6 °C (42.8 °F).
Up to this temperature limit the ice detector operates in normal mode (Heating ON,
when the conditions for switching it on are satisfied). Below this temperature the ice
detector will be in “Stand by” mode. Attention: The temperature range set here has
priority over the base temperature.
Temperature setting
The TEMPERATURE menu item is called up with the MENU button and the desired
temperature set with the VALUE button and the value is saved by pressing ENTER.
An optimum temperature setting is +3 °C (37 °F).
Moisture setting:
The MOISTURE menu item is called up with the MENU button and the desired setting
selected with the VALUE button. The value is saved by pressing ENTER.
An optimum moisture setting is 5. If there is a greater danger of pollution a setting of 6 or
7 must be made. If the heating switches off too early, even though conditions are still
humid, you can prevent this by adjusting the moisture value to 3 or 2.
Base temperature setting
The BASE TEMP menu item is called up with the MENU button and the desired setting
selected with the VALUE button. The value is saved by pressing ENTER. We recommend a
setting of –5 °C. The higher the set temperature, the higher the heating costs will be. This
menu item is hidden in the roof application.
Please ensure that the ground temperature set value is not lower than the lowest ground
temperature value set.

2: During the initial installation the default value for the Language menu item is German, for the display
menu item, °C, for the application menu item, Ground, after which these menu items no longer form part
of the default settings.
In the default settings (standard program) the heating will be controlled by a
combination of temperature and humidity. The heating is switched on when the
temperature falls below 3 °C (37.5 °F) and the humidity exceeds 3. If the temperature falls
below 3 °C (37.5 °F) the set post purge time will be switched on. The heating will be
switched off once the post purge time has expired. If the humidity of 3 is exceeded the set
post purge time will turn on and the heating will be switched off once this time has
elapsed.

BASE TEMP
–5 °C (23 °F)
The BASE TEMP menu item is set at –5°C (23 °F), the rest of the settings are as in point 1.
The operation is as described in point 1. An added factor is that with a temperature
beneath –5 °C the heating will be switched on regardless of the humidity and will stay
switched on until the temperature goes above –5 °C (23 °F). If the subsequent heating
time is set the heating will stay switched on till the time has elapsed.

If the MOISTURE menu item is set to OFF the ice detector will thermostatically control the
heating. If the set temperature falls below the preset value the heating will be switched
on and if exceeded the heating will be switched off depending on the post purge time.
5. Monitoring the heated area when there is a drop in temperature
This function is only possible when the air temperature sensor TFD 524 004 is connected
(see connection diagram EM 524 89 Using open space heating).
If there is a sudden several degree drop in temperature and it drops below 7 °C (45 °F)
then the heating is switched on as a precaution for 1 hour as it is highly likely that it will
rain and the temperature will decrease. Depending on the set temperature and humidity
the heating will stay switched on or will switch off after 1 hour.
This sensor must be installed as well as the default sensors (Ice and snow sensor
ESF 524 001/011 and combined temperature and humidity sensor TFF 524 022/012). They
should be fitted in a covered area approx. 2–3 m above ground level. The sensor
connection is shown in the connection diagram.
Attention:
The air temperature sensor must not be fitted over doors, windows or next to lights
or spotlights.
23
Maintenance
Ensure that the surfaces of the ESF 524 001/011, TFF 524 002/012 and ESD 524 003
sensors are kept clean at all times.
A regular inspection of the control unit is recommended so that any alarm messages can
be recognised and rectified in a timely fashion. Only then will it be possible for the system
to operate flawlessly.

Brief operating instructions for ice detector EM 524 89
for open space and gutter heating
Application:
The ice detector is used for the fully automatic electric heating of open spaces, garage
drives, stairs, ramps, flat roofs and gutters. Unlike manually-controlled (touch
dependent) or thermostatically-controlled (temperature dependent only) systems, the
heating will only be switched on if there is a danger of slippery conditions such as snow,
ice or sleet and will, naturally, be switched off after thawing. This ensures energy savings
of up to 8 0 % compared with thermostatically-controlled systems.
Operation:
For problem free operation a default program is saved. The ice detector works on the
basis of this default program after installation.
These settings can be recalled at any time using the STANDARD PROGRAM menu item.

Use the MENU button to select all of the menu items in order. The selected menu item is
shown in the top display line. The bottom display line shows the current value for this
menu item and “ACTIVE”.
For example:
TEMPERATURE
3 °C ACTIVE
The desired value can be changed with the VALUE button. When the highest desired value
is reached and the button is pushed again it will start at the lowest value again. The
current desired value is marked with the word ACTIVE. If another value is selected only
this will be in the bottom line. According to the above example after pressing the VALUE
button 4 times the display would be:
TEMPERATURE
0°C
If this value is now to be applied press ENTER. The new value will be applied to the control
program and displayed with the word ACTIVE. The display is now:
TEMPERATURE
0°C
ACTIVE
If you do not press ENTER or if after you have selected the new desired value with the
VALUE button another menu item is selected with the MENU button, the new value will
not be applied. If no button is pushed for 10 seconds the display changes to ”Measured
value“ mode. The mode changes between display of the measured temperatures on the
one hand and the humidity and the heating on the other at 3 second intervals. If the
supplied resistor is connected instead of the air temperature sensor, the value for the air
temperature is not shown.

measured values continue to be displayed:
For example:
