  Note! If you want to use the thermostat as a room or combination thermostat, you need to order an additional room sensor, product number ECOAC2.

Installation

• 3.1. Mount the thermostat onto a DIN-rail.

• 3.2. The thermostat does not have a main switch on the product itself. Install a main switch elsewhere in the circuit.

• 3.3. Connect the thermostat in accordance with figure 1.

  • The thermostat has screw connectors. The stripping length is 8mm.
  • Connect the floor sensor to the Floor S1 and S2 connectors.
  • Connect the room sensor to the Room S1 and S2 connectors.
  • Connect external temperature control to the connector marked with ΔT. You can use any phase for the external temperature control. The default for external con-trol is 10 °C. You can modify the settings with the Ensto Heat Control application.
  • A fault current switch with a nominal operating current of max. 30 mA must be installed.

• 3.4. Make sure that the heating load is equivalent to the thermostat power rating.

• 3.5. Measure the insulation resistance and the circuit resistance of the heating load controlled by the thermostat. See the correspondence between temperature and the sensor resistance value on Table 1.

• 3.6. Put the floor sensor cable in a dry protective tube between heating cables.
  Note! Make sure, that there is not water in the protective tube.

• 3.7. Route the room sensor cable in a protective tube to the room to be heated. Install the sensor in an appliance box for example with a cable tie. Install the sensor at the height of approximately 1,5m measured from the floor. Protect the sensor with a centre plate, product number LS994BWWFI. You need also a cover frame to complete the assembly, product number LS981WW85FI.

Commissioning and Operation

• 4.1. Turn on the thermostat with the separate main switch.
  • The default mode for the thermostat is “Floor”. You can change the operation mode with 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.
• 4.2. Adjust the floor temperature by turning the adjustment wheel C. The termostat switches on the heat, when the floor temperature measured by the floor sensor is lower than the set value.
• 4.3. The thermostat uses a 47 kOhm 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”.
• 4.4. 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 A alternatively. The blink-ing 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 the Application

• 5.1. Download the Ensto Heat Control application from Apple Store or Google Play, figure 3.

Note! Pair your mobile device and thermostat only via the Ensto Heat Control ap-plication. 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 application 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 application 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 commission-ing. 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 4:
  • Switch on the thermostat with the separate main switch.
  • Press the adjustment wheel C on the thermostat for 1 second [1]. The blue LED indicator A blinks [2].
  • When the application has found your thermostat, your mobile device displays the default name ”New thermostat” .
  • Press the ”New thermostat” button within 45 seconds [3].
  • The blue LED indicator A turns off, when the pairing is completed or 45 seconds is exceeded.
  • Now you can find your thermostat in ”Devices / My devices”.

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 temper-ature. Select the floor setting temperature with the adjustment wheel C.

  • In ”Room” mode the thermostat adjusts the heating according to the room tem-perature. In this case a room sensor is needed. Select the room setting tempera-ture with the adjustment wheel C.

  • In ”Combination” mode the thermostat adjusts the heating according to the room temperature as well as according to the minimum and maximum floor tempera-tures. Define for the floor material appropiate minimum and maximum tempera-tures from ”Settings / Floor temperature limits”.
    If the floor temperature rises higher than the set temperature, the blue LED indi-cator A blinks four times per minute as a warning and the load switches off until the floor temperature has dropped sufficiently. This operation method is intended to protect sensitive floor materials such as parquet. Most parquet manufacturers recommend the maximum temperature of floor covering approximately 27°C. Note! The floor sensor only measures the concrete temperature. The floor cov-ering material temperatures are usually about 5°C lower than the concrete tem-perature, in which case the maximum limitation temperature can be set at about
    + 32°C. It is recommended to set the limitation as low as possible and raise the value afterwards if necessary. However, each flooring material is unique, so when an accurate temperature limit is required, the floor temperature must be checked with a separate thermometer.

  • 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 wheel C. 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 wheel C on the thermostat.
  • The change may be either a rise or a drop in temperature.
  • The blue LED indicator A 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, during week-ends you may want to drop the temperature overnight. Note! When making set-tings 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.
• 5.7. The “Calendar”, “Boost” and “Vacation” buttons are on / off buttons. When the temperature change is activated, the “Calendar” and “Vacation” buttons are green, the “Boost” button is orange.
• 5.8. Press the button on home display to enter the editing mode.

5.9. When the function ”Adaptive temperature change” is active, the thermostat will advance the heating, so that the desired temperature has been reached at the sched-uled time. By default, the function is on.
External Temperature Control

• 5.10. You can use external temperature control, if external voltage is connected to the thermostat.
  • Disable / Enable the function from “Settings / External control”.
  • From “Temperature” you can set the desired temperature value. The default tem-perature setting for external control is 10 °C.
  • “Temperature change” can be either a rise or a drop in the set point temperature.
  • The blue LED indicator A is on when the temperature change is in use.
  • If the external control is enabled you cannot use the adjustment wheel for setting temperature.

Resetting the Factory Settings

• 5.11. Reset the factory settings:
