3.2 Product description

3.2.1 Ventilation unit

● Low energy consumption through electro-
nic volumetric flow control for a constant air
flow. Degree of heat provision up to 89%.
● Savings of approximately 50 % on electri-
cal power consumption through the "Plus
function" (summer operation with exhaust
fan). The "Plus function" can only be
activated with the digital RLS D1 WR
room air control.
● Fans, with particularly energy-saving
DC motor.
● Separate setting for the supply air and
exhaust air quantities for ventilation levels
1, 2 and 3 are possible Air volumes can be
adjusted by a trained electrician through
6 potentiometer adjusters on the control
circuit board.
● Volumetric flow range from 80...300 m³/h
or 100...400 m³/h, depending on the unit
type. The pre-selected volumetric flow is
maintained even in the case of system
pressure changes caused, for example,
by dirt in the filter.
● The highest permitted resistance in the
channel system at maximum ventilation
power is 150 Pa. Increased resistance in
the channel system reduces the ventilation
power.
● Safety circuit breaker for the fans. Both
fans switch off automatically if the front
shutter is opened.
● Simple filter exchange without using tools
In the outside and exhaust air, each with air
filter of filter class G4. Also with pollen filter
of filter class F7 in the outside air.

● Frost protection monitoring. Prevents
the heat exchanger from freezing up at low
temperatures.
● A frost protection temperature sensor moni-
tors the temperature at the heat exchanger
permanently. The supply air fan switches
off if the temperature at the heat exchanger
falls below the preset frost protection
switch-off value (see also Chapter 9.6.4).
The fan remains switched off until the
temperature at the heat exchanger reaches
the frost protection switch-on value again
(see also Chapter 9.6.4). Only then does
the supply air fan switch back on.
● Plate heat exchanger: The supply air and
the exhaust air are fed through the heat
exchanger in separate channels for the
heat transfer.
● External bypass (option). Bypass shutter
can be adjusted by hand. Cool outside air
can be fed past the heat exchanger and
into the supply air channel through the
bypass channel.
● Summer cassette (option): The heat
exchanger is replaced with the summer
cassette during the summer months. When
operating with the summer cassette, the
outside air is fed into the rooms via the
supply air channel.
Recommendation: Only deploy the
i
summer cassette in combination with
pre-cooled outside air, e.g. through an
earth heat exchanger.
● 4x Ø 160 mm duct connections.
● ¾" condensation run-off connections.
For connecting a drain hose. The conden-
sation run-off must run into a siphon as
otherwise unwanted air is sucked into the
ventilation unit through the drain tube, see
also Chapter 9.4.
Further accessories, see also Chapter 11
● TH 10 thermostat (safety device). The ven-
tilation unit switches off if the temperature
falls below the frost protection temperature.
● Electrical preheating register, e.g. ERH 16-2
electric air heater, see Chapter 9.6.5,
connection option 7.
