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’ and ‘S2’ 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 floor.

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

3.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 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

Connection diagram 1

Connection diagram 2

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 settings.

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.

Symbol: Name:	Function:
Plus	Increase Set Point Temperature
Minus	Decrease Set Point Temperature
Time	Change Schedule
Settings	Open Parameters Menu
Manual	Manually Switch Heating Element On or Off
Heating	Change the Operational Mode: (COM, TIME, DRY, ECO, VAC, MAN)
Mode

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
