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.
Heat Recovery ventilation systems effectively contribute to preventing the mould forming on the walls when this is caused by insufficient natural ventilation.
DESCRIPTION
- Very high efficiency decentralized HRU with heat recovery up to 90%.
- Ideal for residential applications and in any environment where it is necessary to ensure a constant thermal comfort both in summer and in winter.
- Suitable for any kind of room.
- A coupled installation is recommended to optimize the system’s efficiency, in a single room or in separate rooms.
- Direct exhaust through walls with thickness from 340 to 500 mm (adaptable to other wall thicknesses from 250 to 1000 mm: see section Dimensions).
- Suitable for conveying air to a max. temperature of 40°C.
FEATURES
- Stylish and ultra-slim front cover. Very compact dimensions.
- High efficiency ceramic heat exchanger.
- Provided with G3-class filters both in intake and in extract, easily removable and washable.
- Free-cooling function.
- EC brushless motor.
- Complies with EN 60335-2-80, LVD 2014/35/EU, EMC 2014/30/EU.
- IPX4
- CE marked
INSTALLATION EXAMPLES
Ideal in noble rooms such as bedrooms and living rooms.
Maximum benefit with coupled installation.
OPERATING SCHEME
REC DUO 100 PLUS RC
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-pulloperation modality at low speed.
REC DUO 150 PLUS RC
Cod. 2RC1502
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 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.
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.
RLS
Cod. 2RV4158
Available upon request as accessory for REC DUO 150 and REC DUO 150 MHY
– On-Off
– Boost speed
REC DUO 150 PLUS RC is supplied with a remote controller,
to select the speed and activate the following operation modalities:
0 On/off
- Push-pull operation modality 24 hours reverse flow running at the selected speed
- Speed 1 Low speed set up (preset at 35 m /h)
- Speed 2 Low speed set up (preset at 50 m
- Boost speed with timer (extraction mode only) 3 3 /h)
- 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).
- Flow control operation in intake or extract mode only. Press once: extraction mode. Press twice: intake mode
- 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 new selected flow.
Led signal:
any time a button is pressed, a led switches on the remote controller to
indicate that the signal has been received.
