Overview

This is the user manual for the HELTUN HE-FT01 Advanced Programmable Thermostat for Fan Coil Heating/Cooling Systems. The HE-FT01 can be flush mounted over standard round or square electrical junction boxes. It is designed to maintain a constant room temperature using internal air temperature sensor.

It is recommended for control of air conditioning/heating systems such as: split/multi-split systems, chillers and fan coil unit systems, central air conditioning systems, multi-zone VRF/VRV air conditioning systems, etc. The fan speed is controlled by three relay outputs. Two more relay outputs control cooling and heating valves. The HE-FT01 has two independent inputs for relay channels which allow it to control fans and valves with different power sources or to use relay outputs as dry contacts. Each relay can carry a load of up to 5A.

The HE-FT01 has an LCD screen with auto-sensing or manually adjustable brightness control, six sensitive capacitive touch-control buttons, and internal sensors for air temperature and humidity. The HE-FT01 is also equipped with light sensor and software energy consumption logic.

The HE-FT01 integrates a Z-Wave 700 platform module allowing it to be used with Z-Wave home automation systems. The HE-FT01 supports Z-Wave ‘S0’ and ‘S2’ security protocols, SmartStart technology, and can be connected (“associated”) to 50 other Z-Wave devices, such as relays, switchers, etc.

You can select one of four operation modes (COM, TIME, ECO, OFF) either manually, or by using a Z-Wave controller/gateway. The HE-FT01 operates in four Climate Modes: Heating & Cooling, Heating only, Cooling only, Ventilation, and has six levels for fan speed control: Low, Medium, High, Auto Medium, Auto High, Off.

The display has a user-friendly interface, showing: air temperature, humidity level, user set point, operating mode, climate mode, fan speed, time, weekday and Z-Wave network status. Display brightness adjusts to ambient light conditions automatically making it always easy to read.

Installation

HELTUN recommends the HE-FT01 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-FT01.

WARNING: Electrical power must be switched off during installation.

1.Placement of the HE-FT01 is of utmost importance for proper operation and must be away from sunlight and sources of direct heat. We recommend installing the HE-FT01 approximately 1.5 meters above the floor.

2.Remove the display unit and backplate of the HE-FT01 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 wires to the HE-FT01 “POWER” terminal by inserting a small Phillips-head screwdriver in the slot beneath each terminal to open. Follow the connection diagram and instructions below:

Figure 1: Connection diagram for 1-valve system

Figure 2: Connection diagram for 2-valve system

Power wires: connect Line & Neutral wires to L & N terminals labeled “POWER”

Fan Speed: connect the required power source for Fan (Relays 1, 2 and 3 outputs) to terminal IN-1-3.

Heating/Cooling valves: connect the required power source for Heating/Cooling valves (Relays 4 and 5 outputs) to terminal IN-4-5.

Loads: Connect the loads to relays output terminals: OUT-1, OUT-2, OUT-3, OUT-4, OUT-5:

OUT-1 for the Fan low speed OUT-2 for the Fan medium speed OUT-3 for the Fan high speed OUT-4 for the heating valve OUT-5 for the cooling valve

4.Make sure the HE-FT01 backplate is oriented on the wall with the word “TOP” pointed upwards. Then secure the backplate onto the electrical junction box using the four screws provided (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.

5.Next, switch ON the main power at the circuit breaker. The HE-FT01 will start up showing the original default factory settings.

6.Remove the clear protective film from the display 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-FT01 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 and turning counter-clockwise 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
Climate	Change Climate Modes and Open Parameters Menu
FAN Speed	Change Fan speed
Mode	Change the Operational Mode: (COM, TIME, ECO, OFF)

The Plus “+” button will increase Set Point temperature by 0.5°C (1°F) with each touch. The Minus “–” button will decrease Set Point temperature by the same 0.5°C (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 (39°F) and the maximum Set Point is 37.0°C (98°F).

The HE-FT01 has four operating states: 1) HEATING (OUT-4 is On, OUT-5 is Off), 2) COOLING (OUT-5 is On and OUT-4 is Off), 3) VENTILATION (both OUT-4 and OUT-5 are Off) and 4) IDLE (all outputs are Off). In the HEATING and COOLING states, in addition to OUT-4 & OUT-5, one output from OUT-1, OUT-2, & OUT-3 will be switched on depending on selected speed. The icons HEATING, COOLING, & VENTILATION are displayed in the center, bottom of the display. Those icons will disappear when the HE-FT01 is in IDLE mode.
