Installation and Operating Instructions
ECO10BTW-J is a floor thermostat which, is designed to control electrical floor heating. The
thermostat is equipped with a 30mA residual current device (RCD) and therefore the product
suits buildings where it is difficult to connect an external RCD to the circuit.

Before Installation

2.1. Make sure that all the parts and tools needed for the installation are available.
2.2. Ensure that the heating load is equivalent to the thermostat power rating.
2.3. Measure the insulation resistance and the circuit resistance of the heating load con-
trolled by the thermostat.
3. Installation
Disconnect the power supply before carrying out any installation or maintenance work on
this thermostat and associated components.
3.1. Mount the thermostat as the cover of a 1-component mounting box or as a part of a
multiple-component instrument panel.
3.2. Put the sensor cable in a dry protective tube between heating cables.
Note! Make sure, that there is not water in the protective tube.
3.3. Connect the thermostat in accordance with figure 1.
• Connect the earthing wires (PE) to the separate connector.
• Connect the temperature change to the connector marked with ∆T. Any phase can be
used to control the temperature change.
• The connectors are screwless. Strip the conductors at the length of 14 mm.
3.4. Check the operation time and operation current of the RCD with a separate test equip-
ment according to the local electrical safety regulations (figure 2).
3.5. Remove the sheath of the sensor cable at a suitable length and put the conductors
through the hole in the installation plate. Strip the conductors at the length of 7 mm. Connect
the wires to the spring connectors (figure 3).
3.6. Mount the thermostat into the mounting box with screws.
3.7. Mount the thermostat frame, cover and adjustment knob (figures 4 and 5). Protect the
thermostat from potential dust during construction.
