3.4.
Check the operation time and operation current of the RCD with a separate test
equipment 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. Con-
nect 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.

Commissioning and Operation
4.1.
Use the switch A to turn on and off the thermostat. The power is turned on when the
slide switch is on extreme position to the right and turned off when the slide switch is on
extreme position to the left (figure 6).
•
The thermostat is in "Floor" mode. You can change the operation mode by using the
Ensto Heat Control 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.
•
The blue LED indicator (C) is on when the temperature change or external control is
active. The default temperature setting for external control is 10 °C.
4.2.
Adjust the suitable floor temperature with the adjustment knob E.
4.3.
You can limit the thermostat adjustment range by using the minimum and maximum
limiters around the adjustment knob shaft (figure 7).
4.4.
Test the function of the RCD regularly (e.g. monthly) by pressing the test button F.
•
When you press the test button, the current should go off and the slide switch should
move to the OFF-position.
•
Turn the slide switch back to ON-position.
•
If the slide switch does not stay on the ON-position, there is a leakage in the circuit.
In that case the thermostat does not allow switching on the current and the product
is operating properly.
•
An electrically skilled person must always examine the reason of the leakage.
4.5.
The thermostat uses a 47kOhm NTC floor sensor by default. If another type of sensor
is connected to the thermostat, change the sensor type accordingly with the Ensto Heat
Control application "Settings / Sensor type".
4.6.
When you use the thermostat in "Combination" or "Floor" mode, the inbuilt fault
detector detects if the floor sensor is defect or missing. The thermostat indicates the fault
by blinking the red LED indicator B and blue LED indicator C alternatively. The blinking stops
when the fault has been repaired.

User Instructions for Ensto Heat Control Application
With this application you can program and change the settings of your thermostat. Blue-
tooth technology is used for the wireless connection. You can connect to one device at a
time. The range in free space is approximately 5m.
Commissioning
5.1.
Download the Ensto Heat Control application from Apple Store or Google Play (figure
