introduction
Type EM 50-1 is an electronic thermostat for fully automatic, economical
control of ice and snow melting systems on small outdoor areas and in gut-
ters. Ice forms due to a combination of low temperature and moisture. EM
50-1 monitors both temperature and moisture, and the heating system is only
activated if a possibility of snow or ice is indicated. EM 50-1 is suitable for
controlling electric heating cables.
glossary
TEMP SET
For setting the temperature at which heating should be acti-
vated.
TIME SET
For setting the afterheat duration. The length of time the
system should continue to provide heat after the moisture/tem-
perature signals have been eliminated by a heating cycle.
CONSTANT
Allows heat to be provided constantly, independently of tem-
perature and moisture.
startup
• Connect a power supply and the LED will light green.
• Adjust TEMP SET to the temperature at which ice and snow detection
should be activated. Recommended initial setting: +3°C.
• Adjust TIME SET to the required afterheat duration (0-5 hours). Recom-
mended initial setting: 2 hours.
• The thermostat is now set up and will begin melting ice and snow when
necessary.
WaRning injury
The appliance may be used by children aged 8 and up and persons
with reduced physical, sensory or mental capabilities or a lack of
experience provided that they are supervised or they have been instructed on
how to use the appliance safely and have understood the resulting risks.
Children must never play with the appliance. Children must never clean the
appliance or perform user maintenance unless they are supervised.
This appliance is designed for domestic use. It can be used safely by un-
trained persons. The appliance can also be used in a non-domestic environ-
ment, e.g. in a small business, as long as it is used in the same way.
Mode of operation/operating instructions
EM 50-1 activates the heating system if the outdoor temperature falls below
the temperature setpoint (TEMP SET) and the moisture sensor simultaneously
detects moisture.
When the outdoor temperature is below the temperature setpoint, the TEMP
LED will light red.
When the moisture sensor detects moisture, the MOIST LED will light red.
When both preconditions (low temperature and moisture) are met, the ther-
mostat will activate the ice and snow melting system, and the RELAY LED
will light red. After the moisture/temperature signals have been eliminated by
a heating cycle, heat will continue to be provided for the specified length of
time, to ensure that all ice and snow is completely melted.

If some ice and snow remains after the heating system has been deactivated,
the afterheat duration should be increased slightly by adjusting TIME SET.
The longer the afterheat duration, the more effective and less economical the
system will be.
If ice and snow is present on the heated area, but the TEMP LED is not lit, the
temperature setpoint (TEMP SET) should be increased to the point where the
TEMP LED lights red. The higher the temperature setpoint, the more effective
and less economical the system will be.
Constant heat On
In order to force ice and snow melting ON in any condition, it is possible to
turn on the output relay, by turnng the TIME SET knob to Constant. The ON
led flashes as long as Constant is activated. Be aware to adjust TIME SET
back at the desired afterrun time, after all snow and ice has melted, to save
energy.
Note that the CONSTANT HEAT ON setting will result in high energy
consumption/costs.

Fault codes
If faults occur, the thermostat disables all outputs and ceases to operate until
the fault has been remedied.
TEMP LED flashes red:
Temperature sensor (EF 50-25 H/ ATF 5) has
been disconnected or short-circuited.
MOIST LED flashes red:
Moisture sensor in sensor (EF 50-25 H/
F 50-10 RH) has been short-circuited.
RELAY LED flashes red:
Heating element in sensor (EF 50-25 H/
F 50-10 RH) has been short-circuited.
