Description EB-Therm 200 P
is a microprocessor controlled ther
EB-Therm 200
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 200 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 1d). EB-Therm 200 also has a programming button (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 V AC 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 200 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 1d). In function modes B and C, only the temperature setting knob is
used to set the floor or room temperature (Fig 1d). Normal setting for A and C is between 3 and 4. Normal setting for B is between 4 and 5.
EB-Therm 200 - programming
EB-Therm 200 has a built-in night setback program which is suitable for the home or office environment. To choose the function, move the jumper as shown in Figs 5g and 5f.
5g shows the jumper position for the home environment (set at the factory) and 5f for the office environment.
Temperature setback times for the home (Fig 5g)
The temperature is automatically reduced by 5°C between the
following times:
Mon - Fri between 08:30 and 15:00
and Mon - Sun between 23:00 and 05:00
Setting the clock
Before the temperature setback program can be used, the clock must be set. The time must be set at 17.00 on a Monday. Press and hold the button (Fig 1c) until the lamp
starts to flash (after about three seconds). The time is now set, ie the clock is set to 17.00 on Monday.
Starting / stopping the program
To start the program, press the button once (Fig 1c). The LED starts to flash once a second. This confirms that the program is running. To stop the program, press the button
once (Fig 1c). The LED stops flashing. The running reserve of the thermostat is four hours. This is the time for which the programming is held in the thermostat in the event of
power failure. After a long power outage the LED lights up brightly. This means that the clock must be re-set again and the program re-activated.
