HELTUN High Load Switch (HE-HLS01)

The HELTUN HE-HLS01 High Load Switch with Thermostat Functions brings incredible capabilities to any connected device: saving energy, wireless control of connected devices, and absolute comfort and convenience for your home. It fits easily behind outlets or switches in standard electrical junction boxes—or in a circuit breaker panel connected to entire banks of lights or outlets — making them "Impossibly Smart" with over-the-Internet monitoring, control, and advanced programmability.

Full thermostat functions

The High Load Switch provides Internet-connected thermostat functions where a local display and controls are not needed such as roof or driveway de-icing systems. An included NTC temperature sensor can be installed on the wall, under floorboards, on the roof, or under decking allowing accurate monitoring of ambient or radiant floor/roof system temperatures.

Inputs & outputs

It can also be connecting to external switches or systems—such as a light switch or alarm system, etc.— through a pilot wire to allow direct or pre-programmed control of connected devices using eight different modes.

Know how much energy you use

Determine how much energy is used by major appliances, entertainment systems, computers, small appliances, or entire lighting systems by monitoring how much energy has passed through the HE-HLS01 during any particular day, week, or month.

Makes circuit breakers "Impossibly Smart"

Since the High Load Switch can handle up to 16 Amp loads, it is a perfect addition to your circuit breaker panel for monitoring and controlling groups of devices from the Internet through a Z-Wave™ gateway.


The High Load Switch adds safety to your home by protecting against overloads, overheat, sparks conditions, and it can even be configured to turn off an outlet if a family member leaves a high load device turned on for a long period of time, possibly preventing a fire.

Enables scenarios triggered by time

The High Load Switch has an onboard Real Time Clock (RTC) that enables scenarios where connected devices can be triggered on a schedule.

Based on the latest Z-Wave platform

The HE-HLS01 integrates a Z-Wave Plus™ v2 700 platform module allowing it to be used with Z-Wave home automation systems. The HE-HLS01 supports Z-Wave ‘S0’ and ‘S2’ security protocols, SmartStart technology, and can be connected (associated) to other Z-Wave devices, such as relays, motor controllers, dimmers, etc.

Compatible hub / Works with

Aeotec, ComfortClick, Eedomus, Ezlo, Fibaro HC LITE, HC2, HC3, Jeedom, Home Assistant, Homey, Hubitat, RazBerry, SmartThings, Thinka, Zipato gateways and Z-Wave JS library

Heltun compatible hubs

Functions & Features

The functions and features of HE-HLS01 could be different depending on how the device is included in Z-Wave network. Depending on the number of button presses (two or four) during the inclusion process HE-HLS01 could function as either "Binary Switch" or "Thermostat". In case if the device is already included in Z-Wave network and there is a need to change the device type, it should be removed from network and re-included with the corresponding type.
