Installation and Operating Instructions
1. Safety Instructions
• Installation must only be carried out by a electrically skilled person.
• Read the installation instructions carefully before starting the installation work.
• The instruction manual must be stored in a safe location and be available for future installation and
service.
• The information provided in this manual in no way exempts the user of responsibility to follow all appli-
cable codes and safety standards.
2. Before Installation
2.1. Make sure that all the parts and tools needed for the installation are available. This package contains
a thermostat, an adjustment knob, a cover, a frame, an additional connector for earth wires, a sensor cable
and this instruction manual.
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 controlled by the ther-
mostat.
3. Installation
Disconnect the power supply before carrying out any installation or maintenance work on this ther-
mostat and associated components.
3.1. Mount the thermostat as the cover of a 1-component mounting box or as a part of a multiple-compo-
nent instrument panel.
3.2. When the thermostat is used for underfloor heating solutions, 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 earthing wires (PE) to the separate connector.
3.4. Connect the thermostat in accordance with figures 1 and 2.
• The thermostat has spring connectors. The stripping length is 9 mm. The conductors can be discon-
nected from the spring connectors by simultaneously twisting and pulling.
• A fault current switch with a nominal operating current of max. 30 mA must be used.
3.5. Mount the thermostat into the mounting box with screws.
3.6. Mount the thermostat frame and cover (figure 3). Protect the thermostat against potential dust during
construction.
4. Commissioning and Operation
4.1. Turn on the thermostat with the power switch A (figure 4).
• The thermostat is in "Floor" mode. You can change the operation mode by using the Ensto Heat Con-
trol application.
• The LED indicator B is green, when the thermostat is on and the heating is off.
• The LED indicator B is red, when the heating is on.
4.2. You can adjust the thermostat limitation range with the minimum and maximum limiters on the
adjustment wheel (figure 5).
4.3. Check the temperature after approximately 24 hours. If the temperature does not match the set value,
calibrate the thermostat (figure 6).
• Remove the adjustment knob and shaft without changing the thermostat setting (1).
• Pull the knob out from the shaft toothing (2).
• Put the shaft to the original position (3).
• Put the knob on the toothing in such a manner, that the knob indicates the actual temperature (4).
• Set the desired temperature with the adjustment knob (5).
