Description
EB-Therm 300 is an electronic thermostat with LCD display. The thermostat
has three separate temperature control functions. You can choose between
room thermostat, floor thermostat or room thermostat with overheat
protection in the floor. The thermostat has three temperature setback
programs: two of them are pre-programmed (for homes or offices) and one
is for user settings. The EB-Therm 300 is approved for installation in wet
rooms, SEMKO-certified and CE-marked. The thermostat is designed for
flush or surface mounting. The front panel has an LCD display (Fig 1a), a
dual-function LED (Fig 1b) and a dual-function knob (Fig 1c). Settings and
temperature readings are shown digitally and graphically on the display (Fig
1a).
Fuzzy technology
Temperature regulation is based on an algorithm, which uses fuzzy
technology. This means that the thermostat collects data from the start and
calculates when it should switch on and off on the basis of that data. This
approach reduces temperature fluctuations, providing a more uniform
temperature and lower energy consumption. The temperature in the floor
varies by less than +/- 0.2 degrees. See the diagram below.
Installation
Flush mounting - EB-Therm mounts in a standard 65 mm mounting box.
The location should be chosen so that the thermostat is protected from
direct sunlight and draughts. The floor sensor must be installed in a conduit
laid in the floor. The end of the conduit must be sealed to make it easy to
change the floor sensor. All incoming conduits to the mounting box must be
sealed so that the air temperature sensor is not affected by draughts.
1.
Make sure that the mounting box is flush with the wall.
2.
Remove the setting knob. Press the latch (Fig 2a) and lift of the
front cover and the frame.
3.
Connect 230 V AC electric power, the load and the floor sensor
cable. If the floor sensor cable needs to be extended, use
power wiring. Connect the protective conductor for the incoming
supply and for the heating cable with a terminal block in the box
(Fig 3).
4.
Place the thermostat in the mounting box and secure it with the
screws provided.
5.
Refit the frame, front cover and setting knob.
Mounting with distance frame - (E 85 816 68), (Fig 4). Fix the distance
frame to the wall with screws. Then install the thermostat, following the
instructions above.
Mounting in a wet room – Install the IP 21 gasket (21 066 57) (Fig 5).

Temperature
Turning the knob clockwise increases the desired temperature (set point);
turning it anticlockwise reduces it. The actual value reading (the current
temperature of the floor or of the room) may differ from a thermometer
reading, owing to the properties of the room (underfloor heating design,
room insulation, etc.).
Time and date
The thermostat shows the time and the date. The calendar adjusts
automatically for leap years and for summer/winter time. Before the
temperature setback program can be used, the time and date must be set.
This is done as follows (Fig 6):
-
press the knob once
- turn,
choose
SETTINGS
and press
-
turn , choose
SET CLOCK
and press
-
set year, month, day, time and summer/winter time by turning and
pressing the knob
Thermostat settings
The EB-Therm can provide three distinct functions.
•
“R&F” = room and floor thermostat - a built-in sensor regulates the
room temperature between 5°C and 37°C. The external floor sensor
operates as a floor temperature limiter. The limit can be set from 5°C
to 45°C. The factory setting is 27°C.
•
“F” - floor thermostat (factory setting) – The external floor sensor
regulates the floor temperature. The preset value is 22°C.
•
“R” - room thermostat – A built-in sensor regulates the room
temperature. This function cannot be chosen when the floor sensor is
connected. If the floor sensor is not connected when the system is
switched on for the first time, the thermostat chooses this function
automatically.
Functions are chosen as follows (Fig 7):
-
press the knob once
- turn,
choose
SETTINGS
and press
- turn,
choose
THERMOSTAT MODE
and press
-
choose the required function (

&

) and press
Overheat protection – This function protects the floor from overheating. The
factory setting of the overheat protection (27°C) can be changed. This is
how to set the temperature limiter for an external floor sensor (Fig 8):
-
press the knob once
- turn,
choose
SETTINGS
and press
- turn,
choose
OVERHEAT PROTECT
and press
-
set the required temperature by turning and pressing the knob.
