Placement of the HE-FT01 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-FT01 approximately 1.5 meters above the floor.
Remove the display unit and backplate of the HE-FT01 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
wires to the correct HE-FT01 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 “POWER”.
• Fan speed source:
Connect the required power source for Fan to terminal IN-1-3.
• Valves source:
Connect the required power source for Hot & Cold water valves to terminal IN-4-5.
• Fan speed wires:
Connect fan speed control wires to relays output terminals OUT-1, OUT-2, OUT-3:
- OUT-1 for the Fan low speed
- OUT-2 for the Fan medium speed
- OUT-3 for the Fan high speed
• Valves wires:
Connect valves control wires to relays output terminals OUT-4, OUT-5.
If you use two-valves fan coil system, follow diagram on Figure 1 or 3:
- OUT-4 for the heating valve
- OUT-5 for the cooling valve
If you use one-valve fan coil system, follow diagram on Figure 2 or 4:
Connect valve wire to both outputs OUT-4 and OUT-5.
Note:
HELTUN recommends installing cord terminals (electric wire ferrules) on the ends of wires before connecting them to the
HE-FT01 outputs (various colors terminals are included).
Note:
Zero-Cross technology is unavailable if the device uses DC voltage (24-48VDC).
Tighten wires using Phillips screwdriver in slot beneath each wire.
Making sure the HE-FT01 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-FT01 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.
Next, switch On the main power at the circuit breaker. The HE-FT01 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.

INSTALLATION
The HELTUN HE-FT01 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-FT01.
WARNING: Electrical power must be switched off during installation.
