Description EB-Therm 100 D
EB-Therm 100 is an microprocessor controlled thermostat developed for optimal regulation of underfloor heating systems. The thermostat controls the
heating in 3 ways. You can choose between room thermostat, floor thermostat or room thermostat with overheat protection in the floor. EB-Therm 100 is
supplied with a front cover and frame suitable for the Eljo Trend wall box system. An extra front cover suitable for Elko RS is also included. EB-Therm is
approved for installation in wet rooms, SEMKO-certified and CE-marked. The thermostat is designed for flush or surface mounting. The front panel is fitted
with a double-pole switch (Fig 1a) and a dual-function LED (Fig 1b). The temperature setting can be locked on the underside of the knob (Fig 1c). The
thermostat has built-in auto-calibration of temperature sensors and fault monitoring of floor sensors. If the floor sensor is damaged or goes open-circuit, the
thermostat contact opens and the LED starts to flash (twice a second). The floor sensor can be replaced. If the room sensor becomes faulty, the thermostat
must be replaced.
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 +/- 0.3 degrees. See the diagram below. The fuzzy technology can take up to 120
minutes after the thermostat has been connected to complete its learning process.
Installation
Flush mounting EB-Therm mounts in a standard 65 mm wall box. The location should be chosen so that the thermostat is protected from direct sunlight
and draughts. The sensor must be installed in a protective tube in the floor. The end of the tube must be sealed. All incoming pipes and ducts must be
sealed so that the temperature sensor is not affected by draughts.
1. Make sure that the wall box is flush with the wall.
2. Remove the setting knob. Loosen the screw. Remove the front cover and the frame.
3. Connect the 230 VAC electric power supply (Fig 2a), the load (Fig 2b) and the sensor cable (Fig 2c). If the sensor cable needs to be extended, heavy-
current cable must be used. The protective earth (PE) (Fig 2d) is connected past the thermostat via a terminal block.
4. Place the thermostat in the wall box and secure it with the screws provided.
5. Refit the frame, front cover and setting knob.
Mounting with extension frame Extension frame E 85 816 68, see Fig 3.
1. Fix the extension frame to the wall with screws.
2. Install the thermostat as described above.
Wet room installation Use the IP 21 rated gasket E 66 210 06 as shown in Fig 4.
Setting
The EB-Therm 100 can provide three distinct functions.
•
A - Room and floor thermostat – The thermostat regulates the room temperature by means of the built-in sensor. We recommend this setting for
wood floors. The external floor sensor operates as a temperature limiter. The setting as shown in Fig 5a of approx. 27°C applies to wooden floors.
•
B - Floor thermostat (preset at the factory) - The thermostat regulates the floor temperature by means of the floor sensor. Setting as shown in Fig 5d
(maximal turning to the left).
•
C - Room thermostat – The thermostat regulates the room temperature by means of the built-in sensor. Setting as shown in Fig 5e (maximal
turning to the right).
In function mode A the external temperature limiter is normally not changed, but it can be adjusted on the potentiometer, with a small screwdriver. Overheat
protection can be regulated from 15°C (Fig 5b) to 39 °C (Fig 5c). The room temperature is set with the setting knob (Fig 1c). In function modes B and C,
only the temperature setting knob is used to set the floor- or roomtemperature (Fig 1c). Normal setting for A and C is between 3 and 4. Normal setting for B
is between 4 and 5.
