HELTUN High Load Switch is a Z-Wave module that has Thermostatic and Switching functionalities. This is a perfect tool to control your heating system and integrate it into a smart Z-Wave environment providing remote control and energy savings. This is also a great help to control any high load appliances like groups of lights, heaters or individual sockets. There are a lot of use cases to implement with HELTUN High Load Switch:
Heating Functionality
Controlling electric underfloor heating system
HELTUN High Load Switch controls an underfloor heating system by adjusting the temperature of the system based on the desired temperature set by the user. In order to adjust the temperature of the underfloor heating, the NTC sensor is typically placed inside the underfloor heating to measure floor temperature and send temperature readings to the High Load Switch. The NTC sensor is supplied with HELTUN High Load Switch, you may always find it in the product box.
The High Load Switch can also use data from other sensors, such as motion and occupancy sensors, or security alarm, to optimize the heating for energy efficiency. The High Load Switch can also be controlled from the Z-Wave hub that receives data from other temperature sensors and thermostats.
Controlling electric boilers and radiators
HELTUN High Load Switch controls the electric boilers and electric radiators by sending a signal to the boiler or electric radiator to turn on or off based on the desired temperature set by the user. The High Load Switch can also use data from other sensors, such as motion and occupancy sensors, or security alarm, to optimize the heating for energy efficiency. The High Load Switch can also be controlled from the Z-Wave hub that receives data from other temperature sensors and thermostats.
Controlling water heating system and water radiators
HELTUN High Load Switch regulates the temperature in the room by controlling electric water valves based on the desired temperature set by the user.
Retrofit to existing heating system without wiring
HELTUN High Load Switch can make your heating system smart without wiring. In order to do that the High Load Switch should be associated with a Z-Wave valve and will control this valve based on the desired temperature set by the user.
Zone temperature control with HELTUN High Load Switch
Use HELTUN High Load Switch to control one zone in your building by wiring or associating it with water valves inside the zone. The High Load Switch will control the valve(s) based on the desired temperature set by the user.
Measure precisely how much you spend on heating
The High Load Switch precisely measures power consumption of the connected heating system and sends the data to the Z-Wave Hub. You can see how much you spent on the heating for the given time period, total consumption of your building, or consumption of an individual zone.
Using external connections to control heating mode via security alarm or button
HELTUN High Load Switch has external connection inputs S1/Sx to wire external devices like security alarms or buttons. When S1/Sx is short-circuited, the High Load Switch activates preset mode or turns off. Examples of typical use cases:
automatically activate energy-saving mode when you activate an alarm leaving your home,
automatically activate energy-saving mode when you press the bedside “go to sleep” push button.
Retrofit: Making your existing floor heating system smart
Although HELTUN High Load Switch comes with 3-meter NTC sensor in the box, it is possible to connect it to any NTC sensors ranging from 1 to 100 kΩ. Just replace your “dumb” heating thermostat with HELTUN’s smart one and enjoy intelligent functionality that makes your life comfortable and your heating system energy-saving!
Note: If an NTC sensor other than 10 kΩ is used, sensor parameter value should be changed in the settings menu.
Using voice control to regulate heating
Many Z-Wave hubs work with virtual assistants such as Alexa or Google Assistant, which allows you to control connected High Load Switch using voice commands.
Create intelligent programs based on heater temperature and time
HELTUN High Load Switch allows you to set limits for floor (or other heater) temperature, as well on/off time duration. This provides the opportunity to turn heating on or off for the specified period of time but keeps floor temperature within the set limits.
Quickly dry wet floors with DRY mode
Activate DRY mode if a high floor temperature is required for a limited period of time. For example, after washing the floor. A time range of 5 to 90 minutes can be set. As the Dry
Time passes, the High Load Switch will automatically change Mode to the one set in special parameter “Mode To Switch After Dry Mode Operation Completion”.
Vacation mode: super energy saving mode to activate when you leave for some days
Use energy-saving VAC mode when you are planning to be away from home for some period. The factory default temperature set point is 15.0°C, but any temperature from 1°C to 37°C can be set.
Scheduling your heating profiles with TIME mode
HELTUN High Load Switch can have different temperature schedules for Morning, Daytime, Evening and Night. For example, the “Morning” schedule could be set to 22.0°C starting at 6:00. The “Day” schedule could then be set to 17.0°C at 9:00 when everyone has left for work or school, and so on. The set point will be automatically changed upon activation of the next schedule.
Using built-in hardware consumption meter to create scenarios
Energy saving scenarios may be activated based on measured consumption for a given amount of time. For example, decrease heating temperature if certain amount of kWh per month is exceeded.
Using High Load Switch to remove ice from roofs and paths
High Load Switch may be connected to an electrical de-icing system that prevents ice formation. As HELTUN High Load Switch may work at very low 1–4°C set points, it gives you an energy saving solution for keeping your roofs, paths, gutters, downspouts, and eaves constantly de-iced.
Controlling electric fireplaces
HELTUN High Load Switch controls the electric fireplaces by sending a signal to turn on or off based on the desired temperature set by the user. The High Load Switch can also use data from other sensors, such as motion and occupancy sensors, or security alarm, to optimize the heating for energy efficiency. The High Load Switch can also be controlled from the Z-Wave hub that receives data from other temperature sensors and thermostats.
Control water boiler or electric boiler with High Load Switch
There are several ways to control a water boiler or electric boiler with a smart high load switch:
Remote control: High Load Switches can be controlled remotely using a smartphone app or voice commands, allowing you to turn the boiler on and off from anywhere, and you can even set schedules for the boiler to turn on and off automatically.
