EB-Therm 55 Temperature regulator EB-Therm 55 Ebeco Instruction Manual

EB-Therm 55 Temperature controller EB-Therm 55 Ebeco

This is EB-Therm 55
EB-Therm 55 is a microprocessor-controlled thermostat for optimum regulation of underfloor heating sys-tems. The front is fitted with a locka-ble knob for regulating temperature, as well as an on/off switch that shows whether the underfloor heating is in operation.

Temperature control is carried out by means of an algorithm that uses fuzzy technology. The technology entails EB-Therm testing and collect-ing data from start-up, and based on this, calculating when to turn on and off. This technology reduces temper-ature variations and thus provides a more constant temperature and lower energy consumption. The floor temperature varies less than +/- 0.3 degrees.

   Manual Quick guide

Installing EB-Therm
The floor sensor should be mounted in a spiral hose laid in the floor. The hose endings should be sealed so that the floor sensor can easily be replaced.

Installation
Mount EB-Therm in a 65 mm stand-ard appliance box.

1. Make sure the box is level with the wall.

2. Remove the knob and undo the screw as in the illustration. Lift off front and frame.

3. Connect power, voltage 230 VAC, load and floor sensor cable.
   Any extension to the floor sensor cable must be by means of high-voltage current. Protective conduc-tor for incoming feed and for heating cable is connected with a con-nection clip in the box. See wiring diagram below.

4. Insert the thermostat into the ap-pliance box and screw tight with the existing screws.

5. Read the How the thermostat works/Regulating functions sec-tion on how to set the regulating functions.

6. Mount frame, front and knob.

7. If the thermostat is mounted in a multi-compartment frame, the internal corners of this frame must be removed.

Getting started

• After installation, wait 2-4 weeks before starting the underfloor heating. Precisely how long you wait depends on the type of floor you have and the instructions for the floor putty. Then increase the heat gradually.
• In order to adapt the underfloor heating system to your own heating requirements as much as possible, it is important that you read the entire manual.
• If you have any questions about the use of EB-Therm 55, you are more than welcome to contact Ebeco. Call +46 31 707 75 50 or send an e-mail to support@ebeco.se. Feel free to visit ebeco.com for more information.

How EB-Therm works

This section describes all you need to know about how EB-Therm 55 works and how you set it.

Turning EB-Therm off and on
The heating is not controlled in standby mode. Depress the on/off switch for a second to access stand by mode. Return to normal mode by once again depressing the button for a second.

Control functions

• The thermostat can regulate the temperature in three different ways. This enables the comfort temperature and any flooring temperature requirements to be combined. How the settings are adjusted is described on the next page.
• Room thermostat (R) – The thermo-stat has built-in sensors for meas-uring the room’s temperature and controlling the heating.
• Floor thermostat (F) – A sensor in the floor measures the temperature and then regulates the heating accordingly. This is the factory setting.
• Room and floor thermostat (R&F) – The built-in sensor regulates the room temperature and the sensor in the floor functions as a floor temperature limiter. The limitation can be set to between 25°C and 45°C. The factory setting is 35 °C.

Important

• In rooms with large windows that are exposed to solar insolation, we recom-mend the Room and floor thermostat function. In rooms with wooden floor-ing, the Room and floor thermostat function must always be used.

The adjustment of the regulating function, must be done by a quali-fied electrician. The knob and the front first have to be removed. Dis-connect from power supply before removing.

Then slide the control to the required position using a small screwdriver.
The overheating protection is adjusted here.

Temperature

• Regulating function
• EB-Therm 55 regulates the temperature via a sensor in the floor that measures the temperature and regulates the heating accordingly.
• Set the temperature required Change the floor temperature by turning the knob. Min. position on the control corresponds to 10 °C, max. position corresponds to 45°C. An appropriate setting is usually between 2 and 3.
• The temperature does not stabilise until the underfloor heating system has been on for a few days. It might then be necessary to adjust the thermostat’s setting.

Indication

• The colours on the on/off switch show the current status for EB-Therm.
• Red light – the thermostat is on and the underfloor heating is activated. Green light- the thermostat is  on and the underfloor heating is switched off.

Delay between turning off and on
There is a built-in delay in order to avoid unnecessary wear and tear on internal components and to extend the life of the thermostat. If you raise the desired temperature so that the thermostat comes on, and then lower it shortly afterwards, then it takes 30 seconds before it goes off again.

Key lock button
When you have found a suitable setting for the temperature you can lock the knob. This prevents the control being changed accidentally.
See illustration below. First remove the knob. Then move the two plastic parts so that they define the interval required. Replace the knob.

Troubleshooting

Important : The underfloor heating system is an electrical power installa- tion and any faults must therefore be remedied by a qualified electrician.

Fault indication

• If the floor/room sensor is damaged or interrupted, the thermostat will cut out and the lamp start to flash alternatingly green and red.
• If the floor sensor should become faulty, it can be replaced provided it is installed in a spiral hose laid in the floor as instructed. The room sensor cannot be replaced. The thermostat must be replaced if there is a fault with the room sensor.

Test values for floor sensor

• The following values apply when the floor sensor’s measurements are checked.
