How does Wunda Home regulate temperature?
Your Wunda Home system uses advanced algorithms to manage the temperature efficiently and effectively.
Radiator Control
The Smart Radiator Heads utilise a Proportional Integral Derivative (PID) algorithm to regulate the flow of hot water into the radiators. This method ensures that the room remains close to the set temperature with minimal overshoots. Various factors, such as open doors, windows, or additional people in the room, can affect the temperature, making it challenging to maintain a constant temperature.
The PID algorithm allows the radiator head to open partially and call for heat even when the room temperature is near the setpoint. This proactive approach prevents significant temperature drops, ensuring energy efficiency by reducing the boiler's workload. If an ON/OFF algorithm were used instead, it would result in larger temperature fluctuations, requiring more energy to maintain the desired temperature.
Underfloor Heating (UFH) Control
When managing a UFH system, the thermostats employ an ON/OFF algorithm, and the UFH auto balancing actuators or flow meters regulate the water flow into the UFH loop. This system ensures that the room reaches the desired temperature efficiently.
Additional options
Adaptive Mode - Early Bird & Premium users
Each room can utilise Adaptive Mode in conjunction with scheduling. This function ensures the room reaches the desired temperature by the start of the scheduled heating period, providing greater comfort at the cost of slightly higher energy usage.
Open Window Detection - Early Bird & Premium users
When enabled, it will disable the heating in a room that has detected a sudden drop in temperature due to a door or window being left open to prevent energy wastage.
Radiator Head Algorithms
You can choose how the radiator heads connected to your system regulates the temperature, with three available options:
1. PID (Proportional Integral Derivative)
This algorithm offers accurate and consistent control by slightly opening and closing the valve to achieve the desired temperature. It is ideal for use with boilers.
2. Limited PID
This mode requests heating only if the temperature falls below the setpoint. Once the temperature exceeds the set threshold, the valve remains consistently closed. This approach balances energy efficiency with comfort.
3. ON/OFF
This mode fully opens the radiator valve when the room calls for heat and closes it once the temperature reaches the desired level according to the switching differential setting. While simple, it can lead to larger temperature swings and higher energy consumption.
By selecting the appropriate algorithm and utilising advanced features like Adaptive Mode or Open Window Detection, the Wunda Home system ensures optimal comfort and energy efficiency in your home.
