KRISONA CTRL-DUO

• The control can manage up to a total of 6 decentralized recovery units.
• In VENTILATION or RECOVERY modes, the recovery units will start to ensure the balance of the general flow in ventilation mode with heat recovery.

Heat recovery mode
• Winter: Extracted air from the room (hot) is exploited to pre-heating the air supplied to the room (cold).
• Summer: Extracted air from the room (cold) is exploited to pre-cooling the air supplied to the room (hot).
• The connected devices cyclically reverse the direction of fan rotation (extracting and introducing air into the environment) with a set cycle time.
• Speed adjustment (of devices) is automatic and ensures the correct ba-lance of the Input/Output flow rates.

Ventilation Mode
• The devices change internal environment air (without recovering heat).
- Even number devices extract air from the environment.
- Odd number devices introduce air into the environment.
• Speed adjustment (of devices) is automatic and ensures the correct ba-lance of the Input/Output flow rates.

Air Extraction Mode
• All connected devices extract air from the internal environment.
• The air flow rates are all in Output toward the external environment.
