2. 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

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.
• The thermostat has screwless connectors. The stripping length for conductors is 14 mm.
• Connect the temperature change to the connector marked with ∆T. Any phase can be used to control the temperature change.

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.

4. 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 ”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.

5. 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 8).

Note! Pair your mobile device and thermostat only via the Ensto Heat Control appli-cation. DO NOT pair the thermostat using the device’s own Bluetooth menu. If you have paired the thermostat from the mobile device’s own Bluetooth menu, the ap-plication is not able to contact the thermostat. To correct the situation first remove the thermostat from the mobile device’s own Bluetooth menu and then pair it via the application. When paired via application the connection works. The thermostat also appears in the mobile device’s own Bluetooth menu.

When pairing allow the Ensto Heat Control application to use the location service, if the application requests it. It depends on the mobile device, if the application needs permission to use the location service from the mobile device itself in order to use the Bluetooth low energy radio on the mobile device. If you do not give the permission, the application is not able to use the Bluetooth low energy radio and the application is not able to connect to the thermostat. The Ensto Heat Control does not collect user’s location information and does not need the location service itself, but the application requires the Bluetooth low energy radio for wireless data transfer between the appli-cation and the thermostat.

5.2. Open the application. In the “DEMO” mode you can practice using the application. The Tutorial video shows application’s features and guides you through the commissioning. At any time, you can go back to the Tutorial through the “Support” menu.

5.3. After the Tutorial, pair your mobile device with your thermostat (figure 9):

• Remove the adjustment knob E (1).
• Switch on the thermostat with the power switch A (2).
• Press the Bluetooth button D on the thermostat for 1 second (3). The blue LED indi-cator C blinks (4).
• When the application has found your thermostat, your mobile device displays the default name ”New thermostat”.
• Press the ”New thermostat” button within 45 seconds (5).
• The blue LED indicator C turns off, when the pairing is completed or 45 seconds is exceeded.
• Now you can find your thermostat in ”Devices / My devices”.
• Put the adjustment knob E in place.

Operation Modes
5.4. Change the operation mode from the menu ”Settings / Mode”.

• In ”Floor” mode the thermostat adjusts the heating according to the floor tempera-ture. Select the floor setting temperature with the adjustment knob E.
• In ”Power” mode the thermostat adjusts the heating without sensors according to power. Select the length of the power cycle from ”Settings / Power mode cycle time”. Select the desired heating power 0 – 100% with the adjustment knob E. The heating operates in cycles of the selected period of time. The heating power (%) you select determines how long the heating is on and off during one cycle. For example, if you select 60 minutes for the cycle time and 60% for the heating power, the heating is on for 36 minutes and off for 24 minutes.

Temperature Change with Calendar, Boost and Vacation Functions

5.5. You can change the setting temperature adjusted with the adjustment knob E on the thermostat.

• The change may be either a rise or a drop in temperature.
• The blue LED indicator C is on when the temperature change is connected.

5.6. You can carry out temperature changes in different ways depending on what kind of a change is needed.

• ”Calendar” is intended for weekly reoccuring events. For example, on weekdays you can drop the temperature overnight and while you are away. Note! When making settings for overnight, the night must be in two sections.
• ”Boost” is intended for a temporary temperature change. For example, after a shower you can raise the temperature in the bathroom, so that the floor will dry faster.
• “Vacation” is intended for long-term changes in temperature, e.g for a weekend break or an annual holiday.
