A recuperator is a vital component of HVAC systems, designed to recover and reuse energy by exchanging heat between incoming and outgoing airflows. Through Pierre’s smart control, users can optimize the operation of their recuperator to improve energy efficiency and indoor air quality.
Key Features:
1. On/Off Control:
• The Pierre system allows remote on/off control of the recuperator, ensuring it operates only when needed, based on room conditions or scheduled automations.
2. Speed Control:
• In addition to turning the recuperator on and off, Pierre provides precise speed control, allowing users to adjust the fan speed based on the current airflow or ventilation needs. This helps maintain optimal air exchange rates and energy efficiency, depending on indoor and outdoor conditions.
3. Automation:
• The recuperator can be integrated into custom scenarios. For example, it can automatically adjust its speed based on indoor air quality, temperature, or humidity, working in sync with heating and cooling systems for optimal energy recovery and comfort.
4. Temperature and Humidity Regulation:
• By managing both the recuperator’s operation and speed, Pierre ensures a balanced exchange of heat and humidity between indoor and outdoor air, contributing to improved indoor air quality and comfort while reducing the load on heating and cooling systems.
5. Energy Efficiency:
• The recuperator helps reduce overall energy consumption by reusing heat from exhaust air, and speed adjustments further optimize energy usage, ensuring the system operates as efficiently as possible.
6. Remote Monitoring:
• Users can monitor and adjust the recuperator’s settings via the Pierre app, ensuring optimal operation whether they are at home or away.
This smart integration of recuperators with Pierre enhances control over ventilation and heat recovery, ensuring better energy savings and indoor climate management

What happens if there is a power outage?
If the power goes out, smart devices will retain their last state and resume functionality when power is restored. For critical devices, battery backups can be used to maintain operation during an outage.
Is a thermostat required?
No, a classic thermostat is not necessary. Instead, a temperature sensor integrated with the PIERRE system can monitor the room’s temperature and manage the heating/cooling devices accordingly.
Does Pierre have its own thermostat?
Yes, PIERRE offers its own smart thermostats, which can be found in the thermostat product category.
If I remove an old thermostat, can I replace it with a PIERRE display for heating control?
Yes, you can replace an old thermostat with a PIERRE display, as long as the display includes a temperature sensor for temperature monitoring.
Can a display work as a thermostat?
Yes, most Pierre displays have built-in temperature sensors and can control heating/cooling systems just like a thermostat. All displays have relays that can send signals to heating/cooling devices to turn them on or off.
How can heat quantity measurement be solved with the PIERRE system?
To measure heat quantity, a PIERRE Pro Controller and an Intesis Mbus to Modbus converter are required. The heat meters are connected in series to the PIERRE Controller.
Can I adjust different temperatures in different rooms?
Yes, you can control the temperature room by room.
In a multi-apartment system, how should the circulation pump be controlled?
The circulation pump’s operation is based on automation, so if the valve in any apartment’s floor heating system is activated, it simultaneously activates the circulation pump. If separate control is needed, it can only be handled locally within the apartment.
Regarding heating and cooling, how can I set it up later to ensure the requested hot or cold water reaches each apartment? How can I start the circulation pump per apartment?
Starting from the apartments, the process works as follows: humidity and temperature values are measured in the apartments. To reach the desired temperature, we control the distribution manifolds in the apartments. The circulation pumps for each floor are turned on when any apartment’s distribution manifold valve is open.
Can we program PIERRE so that the valve opens at a given temperature and the pump starts in the valve open position?
Yes, this can be solved per manifold. Alternatively, PIERRE can be programmed so that the valve opens at a certain temperature and the pump starts when the valve is in the open position.
How will the heat pump be connected to the PIERRE system?
The heat pump can be controlled by PIERRE in two ways:
- Winter and summer modes can be switched via a potential-free contact, and a similar contact can be used for starting and stopping the heat pump (start/stop function).
- Modbus RTU communication. It’s important to consult the manufacturer or distributor in advance about the Modbus register addresses and required documentation based on the heat pump model to ensure the proper control process.
What equipment can be controlled by the PIERRE system for starting heat pumps, hot water tanks, and motorized valves in underfloor heating zones?
The motorized valves for underfloor heating zones can be controlled without any issues by the PIERRE system, whether they are On-Off or 0-10V valves. In the mechanical room, the PIERRE system handles the following controls: winter-summer mode switching via a potential-free contact, circulation pump control, hot water circulation pump control, and 0-10V mixing valve control with supply water temperature measurement.
