The principle of thermocyclic heating control
What's new?
Conventional single-room systems are slow. They transfer the room temperature data with long time intervals, turning heat on and off too late, resulting in being either too warm or too cold, sweater on, sweater off or opening a window. They do not sufficiently take into account the energy stored in the room and heating system. Users of underfloor heating get to feel this poor temperature control very strongly due to the large heat inertia involved.
- However, the patented THZ scheme is fast and efficient: it calculates in advance when the actuator or heating unit must be switched on and off. This is made possible by a completely new and unique control method that learns the particularities of each heating system and room independently and adapts to them automatically with a proactive approach.

And how does it work in theory?
Daily heating periods lead to constant fluctuations in temperature, often by several degrees, resulting in a unpleasant room climate. However, on the other hand, the temperature fluctuations do contain information on system constants and environmental conditions. This is exactly where the THZ regulation system comes into play. It extracts this information and regulates these fluctuations down to very small levels. These micro-controlled-fluctuations are continuously evaluated and constantly instruct the control system. The micro-vibration cycles have given the THZ control system its name: Thermocyclic control (German abbreviation: THZ) = heat fluctuation - control.

How does it work in practice?
Microprocessors make this sophisticated form of modelling possible. All the components of the THZ regulation system are therefore based around a microprocessor. Room temperature is measured and processed with the RG or RS room units. This way, the desired (target) temperature can be set.
The ST switching steps switch the radiators or circuits on and off. The switching steps are mounted near the valve (e.g. at the heating circuit distributor) and can control all the valves that can be electrically switched (motor and solenoid valves, thermoelectric actuators, etc.)
The ZE central unit can control up to 30 room units. Up to 30 rooms can thus be regulated - simultaneously yet independently. A large display and an easy-to-understand user guide in plain language help the user make their desired settings. All the data can be accessed via a serial port.
The optional VR flow control regulates the heat provider and sets the optimum inlet flow temperature.
All the components are connected to each other via a simple double line system (bus line). Power is supplied at low voltage via this bus.
