REC Duo 150 Decentralized Heat Recovery Unit
Product Information
The REC Duo 150 is a decentralized heat recovery unit designed
for residential ventilation. It is compliant with the ErP Directive
2009/125/CE and EU Regulation 1253/2014. This double flow unit is
classified as a Residential Ventilation Unit with an energy class A
rating. It features a humidity sensor for improved performance.
The REC Duo 150 is equipped with a ceramic heat exchanger that
accumulates heat from extracted air during the pull cycle and
releases it to fresh air during the push cycle. It is an ideal
solution for noble rooms such as bedrooms and living rooms,
effectively addressing humidity and condensation problems.
Installation Examples
The REC Duo 150 can be installed in two configurations:
- Coupled installation in a single room
- Coupled installation in two separate rooms
Both installation examples offer maximum benefit, providing
efficient heat recovery ventilation.
Operating Scheme
The REC Duo 150 operates in push-pull mode with reverse flow. It
runs for 24 hours in push-pull modality at low speed, which can be
selected between two options during installation. When speed boost
is activated through a remote control switch or RLS controller, the
unit switches to extraction operation modality. The maximum speed
can be set using a timer, adjustable from 0 to 30 minutes. After
the timer concludes, the fan automatically switches back to
push-pull operation modality at low speed.

Usage Instructions
To use the REC Duo 150 PLUS RC, follow these instructions:
- Press the desired button on the remote controller to activate
the corresponding operation modality:
- 0: On/off
- 1: Push-pull operation modality – 24 hours reverse flow running
at the selected speed - 2: Speed 1 – Low speed set up (preset at 35 m3/h)
- 3: Speed 2 – Low speed set up (preset at 50 m3/h)
- 4: Boost speed with timer (extraction mode only)
- 5: Sleep mode – Operation at low speed is frozen for 8 hours to
ensure high acoustic comfort during the night. Press any button
(except button 0) to unblock the function at any time. - 6: Flow control operation – Press once for extraction mode,
press twice for intake mode only. - 7: Free-cooling mode – Air exchange without heat recovery.
Press once to stop the reverse flow and keep the fans running at
the current flow. Press twice to reverse the flow of all fans and
run at the new selected flow.

PRINCIPLE OF OPERATION
REC duo 150 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.

MODELS AND OPERATION
REC DUO 150 Cod. 2RC1500
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 remote control switch or RLS controller (available as accessory). The maximum speed is provided with a timer (adjustable from 0 to 30 minutes). Once concluded the overrun via timer, the fan automatically switches back to the push-pull operation modality at low speed.
REC DUO 150 MHY
Cod. 2RC1501
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 automatically 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. The unit is supplied with a remote controller for the selection and activation of advanced comfort ventilation functions.

The unit switches to the extraction operation modality when speed boost is activated, manually or automatically: 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 concluded the overrun via 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.
