HELTUN HE-HT01 Heating Thermostat User Guide
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 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. For
air temperature proper measurement 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 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).
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 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.
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”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).
6. 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 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. 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.
