HE-HT01 Thermostat for Electric Heating
User Guide

Overview

This is the user manual for HELTUN HE-HT01 Advanced Programmable Thermostat for Heating Systems. The HE-HT01 can be flush mounted over standard electrical junction boxes. It is designed to maintain a constant room temperature by providing sensors for both ambient and radiant floor heating systems. It is recommended for control of electric heating systems (radiator, convection, electric fireplace), boilers, or electric underfloor heating. Heating elements are directly controlled by a single-pole switch. The maximum load for the HE- HT01 thermostat is 16 Amps (4000W @ 250VAC) which must be connected through a circuit breaker.

The HE-HT01 has an LCD screen, six sensitive capacitive touch control buttons, and two temperature sensors (for ambient air temperature and an external NTC floor sensor). It is also equipped with built-in sensors for humidity, illumination, and energy consumption.

The HE-HT01 integrates a Z-Wave 700 platform module allowing it to be used with Z-Wave home automation systems. The HE-HT01 supports Z-Wave S0′ andS2′ security protocols, SmartStart technology, and can be connected (“associated”) to ten other Z-Wave devices, such as relays, switchers, etc.

You can select one of six  operation modes 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 off if the temperature reaches 40°C.

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

Installation

HELTUN recommends the HE-HT01 thermostat 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 off during installation.

1. Placement of the HE-HT01 is of utmost importance for proper operation and must be away from sunlight and sources of direct heat. We recommend installing the HE-HT01 approximately 1.5 meters above the

2. Remove the display unit and backplate of the HE-HT01 from the

3. FIRST ENSURE THE POWER IS OFF at the main circuit breaker, and then test the wires with a probe or multimeter to Insert the power and heater wires to the correct HE-HT01 terminals by inserting a small Phillips-head screwdriver in the slot beneath each terminal to open. Follow the connection diagram and 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
     

4. If using the HE-HT01 for radiant floor 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 Parameter value in the settings menu (Parameter 01 – FSr) – see “Settings Menu” section below.

5. 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.”

6. Making sure the HE-HT01 backplate is oriented on the wall with the word “TOP” pointed upwards, secure the backplate onto 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 first carefully aligning the two top snap connectors, and then gently pushing the entire display unit until it ‘snaps’ into position all the way around.

7. Next, switch On the main power at the circuit breaker (see photo above). The HE-HT01 will start up showing the original default factory

8. Remove the clear protective film from the display unit by pulling on the top right-hand tab.

Disassembly

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

Touch Panel Operation

The touch panel has six capacitive-touch buttons which require minimal pressure to operate.

The Plus “ + ” button will increase Set Point temperature by 0.5°C (or 1°F) with each touch. The Minus “­ – ” button will decrease Set Point temperature by the same 0.5°C (or 1°F). The Set Point temperature is displayed in the bottom left corner of the LCD display under “SET TEMP.”

Note: The minimum Set Point is 4.0°C (or 39°F) and the maximum Set Point is 37.0°C (or 99°F).

The HE-HT01 has two working modes: HEATING (switched On) and IDLE (switched Off). In HEATING mode, the heating element icon ( ) will appear near the right bottom corner of the display (to the left of the connectivity icon). The heating element icon will disappear when the HE-HT01 is in IDLE mode.

Operation Modes

The current Operating Mode is shown on the middle, right of the LCD display under the label: “HEATING MODE.”
The HE-HT01 has 6 Operating Modes:
COM  – Comfort Mode (heating)
TIME  – Time Mode (schedule different Set Point per time and day)
DRY  – Floor Drying Mode
ECO  – Economy (power efficient / energy saving) Mode
VAC  – Vacation Mode (i.e. ‘Away’ Mode)
MAN  – Manual Mode

Change Modes by touching the MODE button (bottom right of display unit) until the desired Mode is reached. Each operating mode has individual temperature Set Points. The HE-HT01 will operate automatically depending on the current Set Point indicated under the SET TEMP label. To change the Set Point value, choose the desired mode and press Plus “ + ” button to increase, or Minus “­ – ” button to decrease. You may alternatively control Set Points through your Z-Wave gateway software.

COM – Comfort Mode (Heat)
This mode is recommended for normal comfort. The factory default set point is 25.0°C (77°F).

TIME – Temperature Schedule Mode (Auto Changeover)
The Temperature Schedule (TIME) Mode can adjust home temperatures automatically to align with your personal habits, saving energy while you are away, and maintaining a comfortable temperature while you are active at home.

The HE-HT01 can have different Schedules for Morning, Daytime, Evening and Night. For example, the “Morning” Schedule could be set to 25.0°C (77°F) starting at 7:00. The “Day” Schedule could then be set to 11.0°C (or 52°F) at 9:00 when everyone has gone to work or school, and so on. Here are recommended Scheduled Set Points for heating during the work week ­ you may wish to change these on weekends depending on your family’s schedule (see example below):

To set up the time and temperature for each Schedule press and hold the Clock “ ” button for three seconds. The display will change to the Time menu.

To set up the start time for each Schedule, choose the Schedule by pressing the Clock “ ” button then adjust the time by pressing the Heating Element “ ” button to increase, or “MODE” button to decrease. Press the Clock “ ” button again to advance to the next schedule and set the time for all four: Morning, Day, Evening & Night.

To choose the temperature Set Points for each Schedule, choose the day of the week by pressing the Gear ” ” button, then choose the Schedule by pressing the Clock “ ” button and adjust the temperature Set Point up or down by pressing the Plus “+” or Minus “­ – ” buttons. Do this action for each day of the week.

Note:  All four Schedules (Morning, Day, Evening, & Night) are the same for all seven days of the week.

Note:  TIME mode will only work properly if the correct current time and date have been set. The time can be automatically corrected from your Z-Wave gateway if the Parameter 9 value is set to 1. Or it can be set manually in Parameters 11, 12, and 13 in the Settings Menu (see below).

Note:  When in TIME mode, the temperature Set Point (under the label SET TEMP) will be automatically changed depending on the Schedule. At any time, the Set Point can be adjusted up or down manually but it will be effective only until the next Schedule.

DRY – Fast Floor Drying Mode
This mode is recommended for use if a high floor temperature is required for a limited period of time. For example, after washing the floor. By choosing DRY Mode, the HE-HT01 will increase the temperature to the selected Set Point for the time specified in the “Dry Time” parameter (Parameter 7). A time range of 5 to 90 minutes can be set. As the Dry Time passes, the HE-HT01 will automatically change to the Mode set in Parameter 8.

To change the Dry Time Parameter, open the “Settings Menu” by pressing the Gears “ ” button for three seconds.

Use the and  MODE  buttons to scroll up and down through the menu to Parameter 07. Then use keys ”  + ” and “­ – ” to increase or reduce the Dry Time setting (in minutes).

To choose the mode to revert to after Dry Time has elapsed (while still in the Settings Menu), press the   or  MODE  button to select Parameter 8, then use keys “ + ” and “ -­ ” to choose the desired Mode as follows:

   VAC| 5|
   MAN| 6| If MAN Mode is chosen, the HE-HT01 will select IDLE state

Note:  Factory defaults for Dry Time are: 30 minutes at 30.0°C (86°F).

ECO – Energy Saving Mode
This Mode can be used if lower temperature and energy consumption is desired. It can also be used at night or when away from all or part of the property for a length of time. The factory default ECO Set Point is 20.0°C (68°F).

VAC – Vacation Mode (Away)
Use Vacation Mode when you are planning to be away from home for some period. The factory default temperature Set Point is 15.0°C (59°F).
Note:  The minimum set point for each mode is 4.0°C (39°F) and the maximum set point is 37.0°C (99°F).

MAN – Manual Control Mode (Off)
In this Mode the HE-HT01 schedules are disabled and the heating state is switched On & Off manually by pressing the Heating Element “ ” button. Note: When in Manual Control Mode the SET TEMP will indicate “OFF.”

Child Lock (LOC)

The Child Lock feature allows you to disable the HE-HT01 touch buttons temporarily. To activate the Child Lock Mode, press and hold the Heating Element ( ) button for five seconds until the Lock Icon ( ) appears in the bottom center of the display.

Input Configuration

Parameter 01 (“FSr”) – Floor Sensor Resistance
If the external floor NTC temperature sensor is used it is necessary to select the correct resistance value in Ohms (Ω) of the sensor. The selection range is 1 to 100 kiloOhms (kΩ). One 10kΩ NTC floor temperature sensor is included in the HE-HT01 package with a 3-meter connection wire. The factory default value is 10kΩ.

Note:  If the floor sensor is disconnected or damaged “—” will be shown on the LCD display under the FLOOR TEMP label.

Parameter 02 (“In 1”) – S1 Input Mode
The HE-HT01 can be connected to the dry output contacts of an external device (i.e. security system) to control the Thermostat operating modes depending on the state of the external device through.
Two different connection diagrams are possible.
Note:  In case of using “S1 connection diagram 2”, it is MANDATORY to connect S1 terminal to the same wire connected to terminal L on the device (labeled as “IN”) through dry contacts of an external device (like wall switch).

If Parameter value = 0 no action will be taken (the input state is ignored by the Thermostat logic).
If Parameter value = 1 the Thermostat will be switched to the operating mode selected in Parameter 3 if the output was short-circuited. The Heating Thermostat will go back to previous mode as soon as the input is open.
If Parameter value = 2 the HE-HT01 will be switched to the operating mode selected in Parameter 3 if the output was short-circuited, but it will not undertake any action if the input is open again.
Note:  The Mode switch is blocked when the Source Sensor (Parameter 4) is: P (value = 5), PA (value = 6) or PF
(value = 7). Factory default value is 0.

Parameter 03 (“In 2”) – Operating Mode For S1 Input Action
This Parameter allows selection of which Operating Mode the HE-HT01 should revert to if the external input is shortcircuited. 1 = COM, 2 = TIME, 3 = DRY, 4 = ECO, 5 = VAC, 6 = MAN mode with IDLE (Off) state, 7 = MAN mode with HEATING (On) state. Factory default value is 6.

Parameter 04 (“SEn”) – Source Sensor
The HE-HT01 has seven Regulation Modes based on different sensors values. Use the Plus “+” and Minus “–” buttons to choose follow modes:

1)  A – Air sensor
2)  AF – Air sensor + Floor sensor
3)  F – Floor sensor
4)  FA – Floor sensor + Air sensor
5)  P – Power regulator
6)  PA – Power regulator + Air sensor
7)  PF – Power regulator + Floor sensor

1. A – Air sensor: Regulation (heating control) is based on the SET POINT applied to the internal room air temperature sensor.
2. AF – Air sensor plus floor sensor: Regulation is based on SET POINT applied to the internal room temperature sensor but also controlled by the floor temperature sensor ensuring that the floor temperature remains within the set limits. The lower floor temperature limit is specified in Parameter 16 (FtL) and the high temperature limit in parameter 17 (FtH).
3. F – Floor sensor: Regulation is based on the SET POINT applied to the external floor temperature sensor.
4. FA – Floor sensor plus air sensor: Regulation is based on SET POINT applied to the external floor sensor but is also controlled by the internal air temperature sensor ensuring that the room temperature remains within the set limits. The lower air temperature limit is specified in Parameter 14 (AtL) and the higher temperature limit in Parameter 15 (AtH).
5. Power regulator: Regulation is based on the time settings for heating which will be ON during the time in Parameter 05 (POn) and then OFF during the time in Parameter 06 (POf). This cycle will be repeated constantly.
6. PA – Power regulator + Air sensor: Regulation is based on the time set by Parameters 05 and 06 but also controlled by the internal air temperature sensor ensuring that the room temperature remains within the set limits. The air temperature limits are specified in Parameters 14 and 15.
7. PF – Power regulator + Floor sensor Parameters: Regulation is based on the time set by Parameters 05 and 06 but also controlled by the floor temperature sensor ensuring that the floor temperature remains within set limits. The floor temperature limits are specified in Parameters 16 and 17.

Example:
In FA mode the SET POINT is set to 30°C, AtL is set to 24°C and AtH is set to 27°C:
a) If floor temperature is lower than 30°C and the room temperature is lower than 27°C the HE-HT01 will operate in HEATING mode.
b) If the floor temperature is higher than 30°C or the room temperature is higher than 27°C then the HE-HT01 will enter IDLE mode which switches off the heater.
c) If the room temperature is lower than 24°C the Heating Thermostat will operate in HEATING mode even though the floor temperature is higher than 30°C.
Caution:  Be careful when setting the lower limitation — Parameters 14 (AtL) and 16 (FtL) — to be sure that the value is not too high and it can be reached. Otherwise the HE-HT01 will stay in HEATING mode.

Notes:

• For safety reasons the HE-HT01 will enter IDLE mode if the floor temperature reaches 40°C despite Parameter settings.
• If there is no floor sensor installed, or it becomes damaged (indicated by ” – – “ in the “FLOOR TEMP”), the regulation mode (A) will be automatically selected as the source sensor. This can only be changed to (P) or (PA). If one of the source sensors is selected from the list (F), (FA), (AF) or (PF), the message “Err” will appear on the screen.
• Factory default value is 3 (F).

Time Configuration

Parameter 05 (“POn”) – Power Regulation ON Time
This Parameter defines floor HEATING time in minutes when Power Regulator (P, PA or PF) is selected as the source sensor in Parameter 04. Time values can be changed in the range: 10 to 240 minutes. The factory default value is 30 minutes.

Parameter 06 (“POF”) – Power Regulation OFF Time
This Parameter defines floor IDLE time in minutes when Power Regulator (P, PA or PF) is selected as the source sensor in Parameter 04. Time can be changed in the range: 10 to 240 minutes. Factory default value is 30 minutes.

Parameter 07 (“dr 1”) – Dry Time
This Parameter specifies how long in minutes the Heating Thermostat will be in HEATING mode when the DRY mode is selected. After this time the HE-HT01 will enter the mode specified in Parameter 8. The time range is 5 to 90 minutes. Factory default time is 30 minutes.

Parameter 08 (“dr 2”) – Mode To Switch After Dry Mode Operation Completion
This Parameter indicates the mode that will be set after Dry Time: 1 = COM, 2 = TIME, 4 = ECO, 5 = VAC, 6 = MAN mode with IDLE state, The factory default value is 1.

Parameter 09 (“tCr”) – Time Correction By Main Controller
If this Parameter value = 1 and the HE-HT01 is connected to a Z-Wave gateway, the HE-HT01 time and day will be periodically polled and corrected from the gateway. To switch off auto correction set the Parameter value to 0. The factory default value is 1.

Parameter 10 (“tFo”) – Time Format
Either 24 hour or 12-hour time formats may be selected. Parameter value 0 = 24 hour format. Parameter value 1 = 12 hour (AM/PM) format. The factory default value is 0.

Parameter 11 (“dAy”) – Day of the Week
This parameter allows manually adjustment of the day of the week in case the HE-HT01 is not connected to any ZWave gateway or Parameter 09 (auto- correction) is selected as 0. The factory default value is 1.

Parameter 12 (“tIH”) – Hour
This Parameter allows manual adjustment of Time:Hours.

Parameter 13 (“tIL”) – Minute
This Parameter allows manual adjustment of the Time:Minutes.

Temperature Configuration

Parameter 14 (“AtL”) ­ Air Temperature Minimum (Lowest level)
This Parameter is the room temperature low limit ­ reading the internal temperature sensor. This only comes into effect if FA or PA are selected as the source sensor in Parameter 04. The factory default value is 21°C (69°F). Note: The AtL value cannot be higher than AtH value ­1°C.

Parameter 15 (“AtH”) ­ Air Temperature Maximum (Highest level)
This Parameter is the room temperature high limit ­ reading the internal temperature sensor. This only comes into effect if FA or PA are selected as the source sensor in Parameter 4. The factory default value is 27°C (80°F). Note: The AtH value cannot be lower than AtL value +1°C.

Parameter 16 (“FtL”) ­ Floor Temperature Minimum (Lowest level)
This Parameter is the floor temperature low limit ­ reading the external NTC temperature sensor. It only comes into effect if AF or PF are selected as the source sensor. The factory default value is 18°C or 64°F. Note: The FtL value cannot be higher than FtH value ­1°C.

Parameter 17 (“FtH”) ­ Floor Temperature Maximum (Highest level)
This Parameter is the floor temperature high limit ­ reading the external NTC temperature sensor. It only comes into effect if AF or PF are selected as the source sensor. The factory default value is 32°C (89°F). Note: The FtH value cannot be lower than FtL value +1°C.

Parameter 18 (“dEg”) ­ Temperature Units
Celsius (value = 0) or Fahrenheit (value = 1) temperature units can be chosen. Floor and air temperature, as well as Set Point and all Parameters will be indicated in the chosen mode. Factory default value is degrees Celsius (0).

Parameter 19 (“AtC”) ­ Air Temperature Calibration
This Parameter defines the offset value for room air temperature. If the internal air temperature sensor is not correctly calibrated, then manual calibration can be made by adjusting the values up to ±9.5°C or ±17°F. This value will be added or subtracted from the internal air temperature sensor reading. The factory default value is 0.

Parameter 20 (“FtC”) ­ Floor Temperature Calibration
This Parameter defines the offset value for floor temperature. If the external floor temperature sensor is not calibrated properly, then manual calibration can be made by adjusting the values up to ±9.5°C or ±17°F. This value will be added or subtracted from the floor temperature sensor reading. The factory default value is 0.

Parameter 21 (“HyS”) ­ Temperature Hysteresis (HyS)
This Parameter defines the hysteresis value for temperature control. The HE- HT01 will stabilize the temperature with selected hysteresis. For example, if the SET POINT is set for 25°C and HYSTERESIS is set for 0.5°C the HE-HT01 will change the state to IDLE if the temperature reaches 25.0°C, but it will change the state to HEATING if the temperature becomes lower than 24.5°C. The hysteresis can be changed from 0.2°C to 10.0°C range in Celsius mode, and from 0.3°F to 18.0°F in Fahrenheit mode. The factory default value is 0.5°C (0.9°F).

Display Brightness

The HE-HT01 has two brightness levels for its LCD display: Active Level ­ when any key is pressed the display becomes brighter, and Inactive Level ­ after five seconds of inactivity the display becomes less bright. The actual display brightness in either level may be adjusted (see below).

Parameter 22 (“Abc”) ­ Display Auto-Brightness Control
The HE-HT01 can adjust its display brightness automatically depending on the illumination of the ambient environment.
