Symaro sensors for flush mounting –

innovative and energy-efficientEnergy-saving Symaro sensors for flush mounting – suited for use

with the range of DELTA switches

22

Symaro™ sensors have an extremely low energy consumption and excel through highly precise measuring

techniques as well as very fast value transmission. They thus establish a sound basis for energy- and cost-efficient

control of the entire HVAC plant.

The sensors for flush mounting are very compact and available in the design of the DELTA switches. As a result,

they fulfill the highest requirements regarding variety of color and design.

1 Worldwide for any requirement

The range for flush mounting

can be used with all types of re-

cessed conduit boxes, worldwide.

Both active and passive types

are available. The active sensors

can be configured in the output

signal ranges DC 0…5 V, 0…10 V,

0…20 mA, 4…20 mA, and

0/4…20 mA and additionally pro-

vide a freely selectable switching

contact for each measuring vari-

able. As a result, Symaro can be

perfectly adjusted to your indi-

vidual requirements.

3 The ideal sensor for every application

The flush mounting range

includes sensors that measure

one measuring variable and

comfortable multisensors that

simultaneously handle several

measuring variables. Symaro

sensors for flush mounting

measure carbon dioxide (CO2),

volatile organic gases (VOC,

mixed gas), temperature, and

humidity individually or in com-

bination – depending on your

requirements.

4 Simple and safe

The front modules of the Symaro

sensors are equipped with snap-

on catches that have been filed

as a patent. The snap-on catches

ensure easy and correct mount-

ing of the front modules onto

the base modules or with pas-

sive sensors onto the mounting

brackets respectively. The stud

for anti-theft protection has also

been filed as a patent: It prevents

unauthorized removal of the

front module.

2 Flexibility in design

In design matters, the sensors

leave nothing to be desired.

With Symaro, you benefit from

the extensive range of colors

and designs of the DELTA switch-

es. The choice is yours: from

classic frames that blend per-

fectly into any room to frames

in exclusive design. The wide

range of frames includes differ-

ent dimensions and is available

for all international standards.

This shows an active sensor. With passive sensors, a mounting bracket has to be used instead of a base module.

Symaro sensors in DELTA switch

design for flush mounting blend

perfectly into any surroundings.

Broad range for flush mounting

in all applications

Symaro offers you a range of sensors

specially developed for flush mounting.

Besides sensors for temperature, humid-

ity, and air quality, the Symaro sensor

range for flush mounting also comprises

comfortable multisensors for the simul-

taneous acquisition of several measuring

variables. In addition, the sensors can

be precisely adjusted to your individual

application thanks to their diverse con-

figuration options, such as active and

passive output signals.

All in harmony – thanks to uniform

room design

Symaro sensors for flush mounting can

be mounted into all types of commer-

cially available recessed conduit boxes,

worldwide. They also meet all installation

requirements: In combination with the

versatile frames of the DELTA switches,

they blend perfectly into any room sur-

roundings. Symaro sensors thus provide

a high level of flexibility and can be easily

integrated into existing as well as new

systems and applications.

Enjoying a perfect feeling of comfort –

while saving energy

Only accurate and expressive measuring

values ensure energy-efficient room con-

trol plus maximum comfort. The sensors’

optimized design enables them to acquire

the measuring variables quickly and accu-

rately. At the same time, disturbances like

the temperature of the wall are compen-

sated for. Hence, Symaro sensors are the

ideal basis for saving energy and costs.

Accurate measuring values are needed

for energy-efficient ventilation, for

example, ensuring that the amount of

outside air supplied to the room does

not exceed the amount actually required.

So air quality sensors are very important

components of demand-controlled ven-

tilation. They acquire the exact CO₂ con-

tent of the room air or the level of mixed

gases produced by paints or given off by

materials. The fan’s output is controlled

depending on these measured values.
