Viessmann offers WiFi

These adaptors are compatible with Wired Wall Controllers, but cannot be used alongside the 24V interface.
Why Choose a Wired Controller (Wall Controller) Instead of a Basic Thermostat?
-
Full Control & Communication
The wall controller maintains full communication with the indoor and outdoor unit. Unlike traditional thermostats that often only allow “setpoint / on-off,” these wired controllers provide full system feedback, status, and control over more parameters: fan speed, operating mode, schedule, “turbo” quick heat/cool, etc.
-
More Information Displayed
You can see more data (mode, fan speed, display codes) directly, rather than guessing or having limited indicators with a standard thermostat.
-
Better Comfort & Efficiency
Full communication allows for more control over fan speeds, schedules, modes, humidity, swing etc.. You can optimize performance more precisely (e.g. Turbo Mode, Eco Mode, Follow Me Function) leading to improved comfort and energy savings.
-
Smart / Intelligent
These controllers are “smart” in the sense that they are built for more than just basic temperature control—they integrate more deeply with the system. These Wall controllers speak the same language as the Indoor and Outdoor unit to allow for uninhibited performance, efficiency and comfort
-
Avoid Limitations of On/Off Thermostat
A typical thermostat just turns the unit on/off based on setpoint. It doesn’t manage fan speeds, or allow for full modulation of the inverter system, and doesn’t communicate status or errors. The wired controller adds all that functionality. Depending on application, a 24V thermostat may still be preferred for its familiar interface and functionalities.
Some Practicals: What to Consider When Choosing Accessories
Are you interested in peak efficiency?
If peak efficiency is your goal, start with a wired controller. For those seeking more advanced features and greater control, wired controllers offer the best option.
Do you already have a smart home ecosystem / thermostat?
If yes, using the 24 V interface may allow integration with what you already have.
Where will the control device be mounted?
Wall controllers are mounted on the wall like a traditional thermostat; remotes/wireless are more flexible.
If you’re considering a Vitocal 100-S for your home or project, the base system already delivers excellent performance and comfort. However, if control, scheduling, feedback or smart home integration are important to you, investing in one of the accessories mentioned above can substantially enhance how you interact with the system. These ad-ons offer far greater flexibility and comfort over simply relying on thermostats or wireless remotes alone. With Viessmann’s ductless accessories, homeowners can enjoy complete control, seamless integration, and the ultimate in year-round home comfort.
