Description

The REC Duo 100 is a push-pull HRU with reverse flow, featuring a ceramic heat exchanger that accumulates heat from extracted air during the pull cycle and releases it to fresh air during the push cycle. Ideal for bedrooms and living rooms, especially effective when installed in a coupled configuration.

Features

• Wireless technology (REC duo 100 PLUS RC)
• Drastic solution to humidity and condensation problems
• Effective in preventing mold formation due to insufficient natural ventilation

Installation Examples

• Ideal for use in noble rooms such as bedrooms and living rooms.
• Maximum benefit can be achieved with coupled installations.

Operating Scheme

The REC duo 100 operates in push-pull modality at low speed for 24 hours, with the option to switch to extraction mode when speed boost is activated. The unit also features a timer for maximum speed operation.

Models and Operation

Available models include REC DUO 100, REC DUO 100 MHY, and REC DUO 100 PLUS RC, each with specific functionalities and accessories for different operational requirements.

OPERATING SCHEME

REC DUO 100 PLUS RC

PRINCIPLE OF OPERATION

REC duo 100 is a “push-pull” HRU with reverse flow. It is provided with a ceramic heat exchanger that accumulates the heat from the extracted air during the “pull” cycle and releases it to the new fresh air during the “push” cycle.

Heat Recovery Ventilation systems effectively contribute to preventing mold from forming on the walls when this is caused by insufficient natural ventilation.

MODELS AND OPERATION

REC DUO 100 Cod. 2RC1100

• 24 hours running in push-pull modality at low speed (selectable between 2 at installation). The unit switches to the extraction operation modality when speed boost is activated through a remote control switch or RLS controller (available as an accessory).
• The maximum speed is provided with a timer (adjustable from 0 to 30 minutes). Once the overrun via a timer, the fan automatically switches back to the push-pull operation modality at low speed.

REC DUO 100 MHY Cod. 2RC1200

• 24 hours running in push-pull modality at low speed (adjustable by the end-user). Boost speed is available in push-pull modality and turns on automatically via humidistat (adjustable from 40 to 90% of R.H) and increases/decreases progressively according to the detected humidity level. In case of a persistent and high concentration of humidity, the unit automati-cally switches to the extraction operation modality.
• It then switches back to the push-pull operation modality at low speed when the humidity level goes below the pre-selected threshold.

RLS Cod. 2RV4158

• Available upon request as an accessory for REC DUO 100 and REC DUO 100 MHY

REC DUO 100 PLUS RC Cod. 2RC1300

• 24 hours running in push-pull modality at low speed (selectable between 2 at installation). The unit switches to the extraction operation modality when speed boost is activated, manually or auto-matically.
• Manually via control switch or RLS controller (available as accessory). The maximum speed is provided with a timer (adjustable from 0 to 30 minutes).
• Once the overrun via a timer, the fan automatically switches back to the push-pull operation modality at low speed. Automatically via humidistat (adjustable from 40 to 90% of R.H.).
• The fan speed increases/decreases according to the humidity level detected above the pre-selected threshold. It then switches back to the push-pull operation modality at low speed when the humidity level goes beneath the pre-selected threshold.
• REC DUO 100 PLUS RC is supplied with a remote controller, to select the speed and activate the following operation modalities:

0 On/off

1. Push-pull operation modality
   • 24-hour reverse flow running at the selected speed
2. Speed 1
   • Low-speed setup
3. Speed 2
   • Low-speed setup
4. Boost speed with timer
   • (extraction mode only)
5. Sleep mode
   • the operation at low speed is frozen for 8 hours to ensure high acoustic comfort during the night. The function can be unblocked at any time by pressing any button (except button 0).
6. Flow control
   • operation in the intake or extract mode only. Press once: extraction mode. Press twice: intake mode
7. Free-cooling mode: air exchange without heat recovery.
   • No reverse flow. Press once: the reverse flow stops and the fans go on running at the current flow. Press twice: all fans reverse their flow and go on running at the newly selected flow.

Led signal: any time a button is pressed, an LED switches on the remote controller to indicate that the signal has been received.
