Controllers and sensors

Control
Ventilation units can be controlled in several ways:
Application for Android, iOS and via a browser (via the HRQ-GATE internet gateway)

Control via CO2 and RH sensors (we recommend as additional control).

Aplication

HRQ-GATE

The gateway is connected to the local network via the Ethernet port. Communication with the device is wireless. On-line control is possible after installing the application on Andriod and iOS or via a browser on a computer. The application graphically illustrates the operation of the device, allows you to change modes and read basic parameters.

Controller LCD, flush-mounted (HRQ-BUT-LCD) This version has an LCD display, allows you to select 1 of 7 operating modes, program the calendar and read additional operating parameters such as temperatures, current fan speeds or the by-pass status. It also allows you to configure ventilation speeds (according to user preferences).

4-button controller

HRQ-SENS-CO2

HRQ-SENS-RH

HRQ-SENS-I-CO2 (flush-mounted)
Each sensor also functions as a controller – it allows you to select from manual modes and, of course, engage AUTO mode. Indicates errors or dirty filters, but there is no filter status reset option.
Motion sensor HRQ-SENS-PIR
The sensor is designed to detect the presence of a person by motion detection and increase the ventilation demand (70% for 15 minutes). In addition, through a relay, the sensor can switch on the light.

HRQ-BUT-LM11

HRQ-BUT-LM04

This controller allows you to choose between 4 modes. The LM04 model has an AUTO button (instead of PARTY), recommended when there is at least 1 CO2 or RH sensor in the system. Signalling of operation and errors by means of a LED diode.

The HRQ-SW3-I rotary switch is an option for wired control of the ventilation unit and allows you to choose between 3 speeds (AWAY, HOME, HOME +)

Modbus gate (HRQ-MODBUS),
HRQ-MODBUS gate, which allows to control the device using the universal modbus protocol and RS485 data transmission.
NOTE! Controller is not included in the kit. During purchase, choose the controller that is right for you. Multiple controllers can be connected at once – e.g. 4-button controller and an Internet gateway.

Heat Recovery Unit PremAIR, SlimAIR and MinistAIR
Controllers and sensors

Constant Flow (CF)
SlimAIR air handling units optionally can be equipped with the Constant Flow system, whose task is to maintain a constant air flow in the installation. CF works by reading the difference between the dynamic pressure around the fan and the static pressure in the duct in front of the fan. The CF system constantly monitors the pressure in the ducts and if the resistance increases, it increases the speed of the fans to maintain a constant flow, such as on the first day when the ventilation unit was commissioned. During exploitation, the installation pressure is naturally disrupted (dirty filters, condensation of water in the heat exchanger, temperature difference changing the air mass). CF counteracts to those changes, thanks to which the airflows remain sustainable, and only a sustainable system takes full advantage of the air handling unit’s capabilities.
Zoning
HRQ-2ZONE is a device designed for residential ventilation systems, dividing the air supply into two controlled and monitored zones. The air flow is controlled by motorized dampers, which are adjusted according to the demand sent by CO2 sensors installed in each zone. Such a system allows for the detection of the habitant’s presence and provides the right amount of fresh air in the right place at the right time.
Connecting the ground heat exchanger
Heat recovery unit has a possibility to connect the ground heat exchanger. This function allows you to control a valve that optionally supply air through the ground-to-air heating system. To do this, install a dedicated damper with the actuator (DATVTML).

Demand Control Ventilation, DCV

The AUTO mode is the most energy-efficient and demand driven mode of SlimAIR units. Operation in the AUTO mode is possible when at least one carbon dioxide CO2 or relative humidity RH sensor operates in the system. In AUTO mode, the sensor (or several sensors) generates the so-called ventilation demand based on ambient air measurements. This request is sent wirelessly to the control board, which sets the efficiency of the fans in the range defined by AWAY and HOME(+ offset) speeds. It means, that in the case of factory settings, the range will be 15-70%. The RH sensor will guard against excessive moisture. If there is a sudden increase in relative humidity (more than 3% within 24 seconds) or the reading exceeds 85%, the sesnor will send 100% demand to the control panel to effectively and quickly reduce the RH level. The CO2 sensor will keep the carbon dioxide concentration below the specified level (the factory default is 800 ppm, you can choose between 700,800,900,1000 and 1100 ppm) thanks to the proportional PID algorithm. This means that the request sent to the control board will change gradually over time until the CO2 concentration decreases. HRU-PremAIR-SENS-C02 sensors have 2 AUTO modes: Comfort and Eco. Comfort is the basic setting (i.e. 800 ppm by default), while Eco increases the limit by 250 (i.e. 1050 by default).

The CO2 sensor is available in the following versions:

surface

flush-mounted

HRQ-SENS-CO

HRQ-SENS-I-CO2

In case of having several sensors, the unit control board will operate according to the highest indication (highest request). In the absence of any demand from the sensors, the ventilation unit will run at AWAY speed (lowest setting).

Cooperation with the kitchen hood
The cooker hood can be connected to the MVHR system via the X25 contact on the main board of the SlimAIR heat recovery units. It is a potential-free contact. Short-circuits of contact inputs will result in an exhaust fan stopping completely during the period the contact is closed.

Smart ventilation system SmartAIR
SmartAIR heat recovery system with zoning is the most intelligent, efficient system on the market. Why is it intelligent? The ventilation system works independently, based on readings from sensors. Besides knowing how many people are in the house, the system also knows where they are. Thus, it provides the right amount of air at the right time and place. A situation like this can be achieved by zoning, i.e. by dividing the house into day and night zones in accordance with the natural cycle of the day of the household members.

Complete EPP system
Choose thermally insulated EPP ducting. High mechanical strength, pre- insulated, and quick to assemble. You don’t need an additional insulation layer. It comes in 15/43mm thicknesses.
EPP manifolds (distribution boxes) Manifolds FLX-PLO-EPP-R are designed for use in domestic mechanical ventilation systems. They collect 75mm semirigid ducting, which is then distributed to the rooms. Typical installations contain from 1 to 2 such manifolds for the supply air and the extract air. Expanded polypropylene (EPP), the material used for the manifolds, is also an insulating material.
Duct and fittings made of EPP in thickness 15 or 43 mm.

Duct-mounted humidifier

The adiabatic humidifier is designed for domestic mechanical ventilation systems with a maximum airflow 600 m3/h. Filtered water naturally evaporates on a special matrix, and then the humidified air is distributed to the ventilation duct system and to the connected rooms. The humidification process is regulated by a wireless room controller and a duct sensor. Built-in PTC heater compensates for temperature losses caused by the evaporation process. The housing is made of EPP, while the matrix is made of fiber glass.
