Stelpro KI STZW402WB+ Z-wave plus thermostat

  Stelpro Z-Wave Plus KI Most thermostats are not compatible with high voltage heating systems. Consequently, many people require numerous thermostats to control their high voltage systems. The most important thing to note is that the Stelpro KI STZW402WB+ can provide up to 4000 watts of power. This means that it can control your high voltage system on its own.  

Although the smart thermostat is powerful, it is energy efficient. With its efficient energy-saving features, it cuts down your electricity bills.

To save on money, this Z-wave line voltage thermostat utilizes four heating levels. Most models do it at one level, allowing the temperature to rise until it passes the set figure. They then await the temperature to drop, and that’s when they can begin heating again. The result is non-uniform room temperature.

Now that this smart thermostat heats in pulses, you are guaranteed an even steady temperature.

On the upside, the smartphone app is supported, letting you regulate things away from home. It is, however, not programmable. To do some customization, you will need to connect to Z-wave.

The biggest handicap is that it doesn’t function with fanned heaters. That is rather mediocre for a device this strong.

  • Installation can be hectic
  • It is not programmable

 Final Verdict 

Putting aside the few drawbacks, the Z-wave line voltage thermostat functions well. If you’re bored of the many thermostats you are using for your system, upgrade to this smart thermostat. It will cut down your energy costs and take your comfort to the next level.

What is a Z-wave thermostat

A Z-wave thermostat is a thermostat that uses the Z-wave protocol to communicate with other smart devices. For that to happen, all the devices, including the thermostat, must be interconnected in a single wireless network. This is effected by a smart hub that works as the central link between the device.  

What is the Z-wave protocol?

The Z-wave protocol is a wireless method of connection used by smart devices. The connection entangles the devices enabling them to communicate.   

What is the function of a Z-wave thermostat?

The work of a thermostat is to sense the temperature of a heating or cooling system then adjust it to a set figure that is considered optimal. They can regulate the temperatures of water heaters, air conditioners, HVAC systems, and typically any other system that deals with heat. If your smart hub can connect to the internet, you can control smart devices remotely using your smartphone.  

Factors To Consider When Buying A Z-wave Thermostat

The market is currently flooded with many types and brands of thermostats. To choose the one that perfectly fits you, there are some factors you need to consider.  


The thermostat you buy should be compatible with the existing smart devices. Do your research well and go to the market knowing which thermostats integrate with which devices. The thermostat should also be compatible with your smart hub. Otherwise, the thermostat will not function.  

Power Source 

Thermostats are either powered by low voltage c wires or batteries. Battery-powered ones are easy to install. Wired thermostats may present a little challenge. If connecting the wires confuses you, find an installation expert.  

User Friendless

It’s important to buy a thermostat that is easy to operate. Check the number of buttons and keep in mind that the fewer buttons it has, the easier it is to operate. Some thermostats are touch screen enabled and are of course easier to use.  

Smartphone Application

Thermostats can nowadays be controlled by mobile apps. They will help you to remotely control your smart home. Don’t buy a thermostat that doesn’t have its app. Also, check the general look of the app. How user friendly is it? How many functions can you perform with it?  


They are set in different places to help the thermostat control the temperature of those zones. Other sensors like the motion sensor make the thermostat sense when you are walking home and adjust to your comfortable temperature.  


This feature is essential when it comes to saving energy. You must have a paired phone in your pocket. When you leave home, the thermostat senses and switches the smart devices into energy-saving mode. When you are walking, it will again sense and set the temperature at a comfortable point.  


You should buy a thermostat that constantly gives you alerts when the temperature reaches critical levels. This way, you will take action before something dangerous happens.  


Some thermostats are expensive literally for no reason. If the thermostat comes with a high price tag, confirm whether they are additional superior features. Otherwise, you will spend extra money for nothing. Better buy a cheap thermostat whose features are well known.  


A good company should give a fairly long warranty. A company that sells you a thermostat without any warranty clearly tells you that they also don’t trust their product.  

The Design

The make and design of thermostats change overtime. Recently, they have sleek well-rounded bodies. Of course, you don’t want a thermostat that looks old-fashioned. Choose the one that appeals to your eye.
