HELTUN HE-HT01 Heating Thermostat - Fig. 1-4

OVERVIEW

The HELTUN HE-HT01 Advanced Programmable Thermostat is elegantly designed and ‘Impossibly Smart’ providing wireless over-the-Internet control of your home’s heating system. The HE-HT01 is ‘Impossibly Thin’ on the wall yet packed with features to help you save energy while providing the ultimate in comfort and convenience.

Controls electric heating systems

The HE-HT01 is designed to maintain constant room and floor temperatures by providing sensors for both ambient and radiant floor heating systems. It controls electric heating systems like radiators, convection or electric fireplaces, plus boilers, and electric underfloor heating. Heating elements are directly controlled via a 16 Amp switch.

Multiple built-in sensors

The HE-HT01 has an LCD screen, six high sensitivity capacitive touch buttons, and two temperature sensors for monitoring: ambient air temperatures, and foor temperatures using the included external NTC sensor. It is also equipped with built-in sensors for: humidity, illumination, and energy consumption. You can instantly access information from all sensors on the user-friendly display.

Monitor all important information without even a touch

The at-a-glance display shows: ambient air temperature, foor temperature, user set point, humidity level, current operating mode, time, day of the week, and status of the Z-Wave network & relay. Display brightness adjusts to ambient light conditions automatically making it always easy to read.

Highly configurable with automatic safety

You can select one of six operation modes with individual set points either manually, or by using a Z-Wave controller/gateway. As a safety measure, the HE-HT01 protects radiant floor systems from overheating by automatically switching of if the floor temperature reaches 40°C.

Know how much energy you use

The HE-HT01 built-in Power Consumption System precisely monitors how much energy you used during any particular day, week, or month.

Based on the latest Z-Wave platform

The HE-HT01 integrates a Z-Wave Plus v2 700 platform module allowing it to be used with Z-Wave home automation systems. The HE-HT01 supports Z-Wave ‘S0’ and ‘S2’ security protocols, SmartStart technology, and can be connected (“associated”) to other Z-Wave devices, such as relays, switches, etc.

INSTALLATION

The HELTUN HE-HT01 thermostat must be installed by a licensed electrician in a manner that conforms to local regulations and building codes. Provide these instructions to the licensed electrician who is installing the HE-HT01.

WARNING: Electrical power must be switched of during installation.

Placement of the HE-HT01 is of utmost importance for proper operation and must be away from sunlight and sources of direct heat. For air temperature proper measurement we recommend installing the HE-HT01 approximately 1.5 meters above the floor.
Remove the display unit and backplate of the HE-HT01 from the packaging.
FIRST ENSURE THE POWER IS OFF at the main circuit breaker, and then test the wires with a probe or multimeter to verify. Insert the power and heater wires to the correct HE-HT01 terminals by inserting a small Phillips-head screwdriver into the slot beneath each terminal and unscrew to open.
Follow diagrams on Figure 1 (or 2 or 3 or 4) and the instructions below:
• Power wires : Connect Line & Neutral wires to L & N terminals labeled “IN”.
• Heater wires : Connect Line & Neutral wires to L & N terminals labeled with Heating Element graphic .
Note : HELTUN recommends installing cord terminals (electric wire ferrules) on the ends of wires before connecting them to the HE-HT01 outputs (various colors terminals are included).
Tighten wires using Phillips screwdriver in slot beneath each wire.
Note : It is possible to connect Neutral wire from heater directly to your neutral line (Figure 2 or 4).
Note : Zero-Cross technology is unavailable if the device uses DC voltage (24-48VDC).
If using the HE-HT01 for radiant foor heating, connect the NTC temperature sensor wire to the terminals labeled “NTC”. A 10 kΩ NTC sensor is included inside the HE-HT01 packaging, but any NTC sensor can be used.
Note : If an NTC sensor other than 10 kΩ is used, you must change the sensor resistance value in the settings menu (Parameter 10 – FSr).
Note : If the floor sensor is disconnected or damaged “—” will be shown on the LCD display under the FLOOR TEMP label.
If you will be using an external device to select modes for the HE-HT01 (such as a security system), connect wires from the external device’s dry contacts to the two HE-HT01 terminals labeled “EXT” or “S1” & “Sx”.
Two different connection methods for external control are possible: (see Figures 1 & 3).
Note : In case of using Figure 3 or 4, it is MANDATORY to connect S1 terminal to the same wire connected to terminal N on the device (labeled as “IN”) through dry contacts of an external device (like a wall switch).
Making sure the HE-HT01 backplate is oriented on the wall with the word “TOP” pointed upwards, secure the backplate to the electrical junction box using the four provided screws (do not overtighten).
Once the backplate is secured onto the wall, assemble the HE-HT01 display unit onto the backplate by frst carefully aligning the two top snap connectors, and then gently pushing the entire display unit until it ‘snaps’ into position all the way around.
Next, switch On the main power at the circuit breaker. The HE-HT01 will start up showing the original default factory settings.
Remove the clear protective film from the display unit by pulling on the top right-hand tab.

DISASSEMBLY

To disassemble, ENSURE POWER IS SWITCHED OFF at the main circuit breaker AND THE LCD SCREEN IS BLANK.
To remove the HE-HT01 display unit grasp firmly at the bottom and pull backwards while tilting outwards until all tabs disconnect.
Remove screws from backplate and disconnect the wires by inserting a small Phillips-head screwdriver into the slot beneath each wire and unscrewing to release.

Z-WAVE NETWORK

The HE-HT01 may be operated in any Z-Wave network with other Z-Wave certifed devices from other manufacturers. The HELTUN HE-HT01 will act as a ‘repeater’ for other devices regardless of manufacturer or brand to increase the reliability of the overall network.

Frequency Region

The Parameter 1 (“ Eg”) allows you to manually change the Z-Wave frequency which is mandated in your geographical region. Modification is possible only while the HE-HT01 is in a ‘Non-Included State.’ While in an ‘Included State’, the Antenna icon will be shown at the bottom right corner of the LCD screen and modification of this Parameter will be disabled. To navigate through the different values, use the Plus (+) and Minus (–) buttons. After the Frequency Region has been selected, hold the Clock button to save the Parameter value and reboot the device for the new settings to take effect.

Security

S0, S2 unauthorized, and S2 authorized Inclusion Modes are supported. If you use the S2 authorized Inclusion Mode the security key should be used during the inclusion process. The Security Key is printed on a card located with this quick start guide and also on the HE-HT01 backplate (see Figures 9 & 10).

Note : Be sure to save this key. Without the key, it is impossible to perform an Inclusion in S2 authorized mode.

SmartStart

SmartStart-enabled products can be added to a Z-Wave network by scanning the Z-Wave QR Code shown on the product with gateways/controllers that provide for SmartStart inclusion. In this case, no further action will be required and the SmartStart product will be added automatically within ten minutes of being turned on in the vicinity of a network.

To add the HE-HT01 to the Z-Wave network using SmartStart:

Set the main controller in Security S2 Authenticated “Add Mode”.
Input the thermostat DSK to the controller (or scan the QR code).
Power on the device.
Wait for the adding process to complete.
Successful adding will be confirmed by displaying the Antenna with signal strength bars icon in the bottom right corner of the main screen.

Note : The device security code (DSK) and SmartStart QR code are printed on the HE-HT01 back panel plus on the included Security Card (see Figures 9 & 10).

Including the HE-HT01 to an Existing Z-Wave Network

To add the HE-HT01 to an existing Z-Wave network (i.e. “inclusion”), do the following:

Enter “SETTINGS” Mode by pressing and holding the Gear button for three seconds.
Scroll menu to “Parameter 2 – nEt” using the Heating Element button to scroll up, and the “MODE” button to scroll down.
The current state of the network will display in the Parameter Value position (upper right). It should display “EcL”.
Note : If “InC” is displayed, the HE-HT01 must first be Excluded from an existing Z-Wave network (see “Exclusion” below).
Start the Inclusion Mode from the gateway/controller.
On the HE-HT01 in Parameter 2, press the Plus “+” key to start the Inclusion process.
Note that lines will be moving in the Parameter value position (upper right).
The Antenna with signal strength bars icon should appear at the bottom right corner if Inclusion was successful.
If only the Antenna icon or “Err” is displayed in the Value position, the HE-HT01 Inclusion was not successful (try repeating steps 4-7).

Removing the HE-HT01 from Z-Wave network

To remove the HE-HT01 from a Z-Wave network (i.e. “Exclusion”), do the following:

Enter “SETTINGS” Mode by pressing and holding the Gear button for three seconds.
Scroll menu to “Parameter 2 – nEt” using the Heating Element button to scroll up, and the “MODE” button to scroll down.
The current state of the network will be displayed in the Parameter Value position (upper right). It should display: “InC”.
Note : If “EcL” is displayed, the HE-HT01 is already Excluded.
Start the Exclusion Mode from the gateway/controller.
Press the Minus “–” button in the HE-HT01 Parameter 2 to start the Exclusion process.
Note that lines will be moving in the Parameter value position (upper right).
The Antenna icon should appear in the bottom right corner and “EcL” in the value position if the Exclusion was successful.
If the Antenna with signal strength bars icon or “InC” in value position are displayed, repeat the Exclusion process.

Note : If the HE-HT01 has previously been part of a Z-Wave network and not Excluded since, Inclusion is not possible without first performing an Exclusion or Factory Reset procedure.

Note : If the HE-HT01 is included in the Z-Wave network the Antenna icon will appear in the bottom right corner of the main screen with signal strength bars .

FACTORY RESET (RES)

By pressing and holding the “MODE” key for ten seconds, the HE-HT01 will enter Factory Reset Mode, displaying “REs” in the left bottom corner, “y” in top left corner and “n” in top right corner. Press the Plus (+) button to revert to factory settings, or the Heating Element button to cancel. The factory reset will change all the Parameters to their original factory default values and will also Exclude the device from any Z-Wave network.

Note : Please use this procedure only when the network primary controller is missing or otherwise inoperable.
