Summary
The Z-Wave Plus V2 Heltun High Load Switch is an incredibly versatile smart home device
It combines thermostat functions, over-the-internet control, and advanced programmability, making it perfect for controlling outlets, lights, and appliances
With its compatibility with multi-protocol smart home hubs and other smart devices, this switch offers a seamless integration into your smart home network, providing convenience, energy monitoring, and safety features like overload and overheat protection.
Take Control
The HE-HLS01 High Load Switch with Thermostat Functions fits easily behind outlets making them ‘Impossibly Smart’ with over-the-Internet control and advanced programmability. In addition, built-in Power Consumption System helps to monitor how much energy was used. With included NTC temperature sensor it provides thermostat functions where a local display and controls are not needed. The High Load Switch also adds safety to your home by protecting against overloads, overheat, overvoltage, spark and surge conditions.
Impossibly Small

Impossibly Smart
The High Load Switch with Thermostat Functions brings incredible capabilities to any connected device. It makes electric outlets and whole banks of lights ‘smart’ with full remote monitoring, control, and advanced programmability. You can now enable Internet-connected thermostat functions where a local display and controls are not needed, such as with roof or driveway de-icing systems, etc. This brings the convenience of smartphone app control and programmability to ‘dumb’ devices such as electrical outlets & panels, electric water heaters, radiators, fireplaces, and radiant floor or de-icing systems. At 26mm in depth, the High Load Switch is also impossibly small, fitting into any rectangular, round or square electrical junction box, even behind an attached device.
Inputs, Outputs & Sensors
You can connect an NTC temperature sensor to monitor ambient or radiant floor/roof system temperatures. This sensor can be installed on the wall, under floorboards, on the roof, or under decking, allowing you to accurately measure surface temperatures. The HELTUN High Load Switch is fully compatible with NTC sensors from other manufacturers, so there is no need to replace an existing sensor when installing it. You can also control the High Load Switch by connecting it to an external system - like an alarm system - using a pilot wire which could be programmed to automatically reduce the temperature when the house is empty or turn on electric outlets/lights when people come home.
Know How Much Energy You Use
The HELTUN built-in Power Consumption System precisely monitors how much energy has passed through your High Load Switch during any particular day, week, or month. With the High Load Switch, you can determine how much energy is used by major appliances, entertainment systems, computers, small appliances, or entire lighting systems.We have also designed the circuitry so it draws almost zero watts to power itself when in standby mode. This saves you energy and money even if your home is equipped with many HELTUN products.
Thermostat Modes
Even though the High Load Switch does not have a display or buttons, all of its thermostat functions can be accessed through a Z-Wave controller. Here are the available thermostat modes. COM (comfort), ECO (energy-saving), and VAC (vacation) modes maintain the temperature you specified using the Z-Wave controller. DRY mode switches to a rapid heating mode at a higher temperature to dry floors after washing. DRY mode reverts back to the previous mode after the specified time.MAN (manual) mode allows you to override any current mode or schedule and turn the heat ON or OFF manually using your controller interface.
Time Mode: Thermostat
You can reduce your power bill and help the environment just by using TIME mode through your Z-Wave controller. Adjust your home comfort level according to your family’s habits by reducing the temperature while everyone is away, and by boosting it for evenings and early mornings. People spend about 12-14 hours a day at home on average. The rest of the time an empty house needs minimal heating. And considering that much of the time at home your family is sleeping, it can make a huge difference setting your home’s comfort level to 18°C overnight which is considered to be the optimal sleeping temperature. Using TIME mode and your controller, set different temperatures for Morning, Day, Evening, or Night. For example: ‘Morning’ mode might start at 7:00 with 23°C and then shift to ‘Day’ at 8:30 with 17°C when everyone is off to work and school. ‘Evening’ mode might start at 16:00 with 22°C and then shift to ‘Night’ at 23:00 with 18°C. Setting temperatures for these four periods can save a lot on your power bill plus you can adjust for weekdays versus weekend days.
Time Mode: Other Devices
The High Load Switch can be connected to products other than ones that are thermostatically-controlled, such as electric panels, outlets, and banks of lights. Time Mode provides an extremely powerful ability to schedule ON and OFF cycles for groups of connected devices. And just as with the High Load Switch thermostat functions, through a controller you can assign attached devices to be ON or OFF during Morning, Day, Evening, or Night periods. This can make it easy to turn OFF outlets connected to game consoles at night or schedule all outdoor lights for evening turn-ON and morning turn-OFF. The possibilities are limited only by the creativity of the user of the High Load Switch.
Make Circuit Breakers Smart
Since the HELTUN 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, such as: Outlets connected to major appliances, Outlets connected to high load small appliances, Entire groups of electric outlets, Entire groups of lights. The Micromodule Mounting Adaptor is available from HELTUN as an accessory for the High Load Switch to fit standard DIN rails (50mm width), or it can also be mounted directly on the wall using the supplied screws & anchors.
Safety
There are a number of ways that the High Load Switch can add to the safety of your home. Overload – If the High Load Switch detects too much wattage being drawn from connected devices - such as multiple connected electric outlets - it will automatically shut down to protect against circuit overload. This is useful for many applications where multiple loads are connected to one High Load Switch. Overheat – The High Load Switch also constantly monitors temperature offering multiple layers of protection. With an external NTC sensor, it monitors the temperatures inside the junction box enabling automatic disconnection, and notification of the user, if an outlet gets too hot. It can even notify the user of rising temperatures prior to reaching a critical shutoff level, after which it will automatically shut off the outlet when it crosses a dangerous threshold. High Load Timeout – If a family member leaves a device turned ON that draws a lot of power for a long time - such as a clothes iron connected for more than 1 hour - the High Load Switch can be configured to automatically shut OFF connected outlets to prevent a fire. Users can define the high load, time, and temperature shutoff limits and notification settings in the High Load Switch parameters using a Z-Wave controller.
Easy Installation
The HELTUN High Load Switch can be easily installed into any standard electrical junction box (rectangular, square, or round) in just minutes. Installation must only be performed by someone trained in handling high voltage electrical systems.
