1. About this manual
1.1 Ventilation system description
Complete ventilation system consists of:
• Heat recovery ventilation unit MinistAIR
• Ducting with diffusers, plenum boxes, inlet and outlet valves, etc.
• Control button HRQ-BUT-LM11 (optional)
• Control button HRQ-BUT-LM04 (optional)
• Control button HRQ-BUT-LCD (optional)
• CO2 wireless sensor(s) HRQ-SENS-CO2 / HRQ-SENS-I-CO2 (optional)
• RH wireless sensor(s) HRQ-SENS-RH (optional)
• Internet bridge HRQ-GATE (optional)
• Silencers (optional).
Mechanical ventilation provides the best level of comfort inside the building. With this type of ventilation it
is very easy to control amount of air extracted from house or blown to house.
Extract valves are mounted in bathrooms and kitchens. Supply valves are mounted in bedrooms and living
rooms. All ducting must be connected to MinistAIR unit.
In normal operation (bypass is closed and frost protection is not active) unit works in two directions: supply
and extract. Supply air is taken from outside and goes through plate heat exchanger to supply valves. Extract
air is extracted from house and goes through heat exchanger to outside.
In heat exchanger heat energy is transported from extract air to supply air without mixing this two airflows.
With standard control devices like HRQ-BUT-LM11 you can manually set one of three fans speeds (low,
medium and high). If you have optional equipment HRQ-GATE connected to your unit, and an active Internet
connection, you can set this three speed via mobile application PremAIR.
With additional CO2 and RH sensors speed can be controlled automatically depending on CO
2
concentration
and relative humidity level (auto mode should be active).
