NL-MRF-RX-CO2+RH |
The receiver is used for receiving and
processing measured data from wireless air
quality sensors. One or more battery
powered air quality sensors can be paired
with the receiver.
Received data from sensors are converted to
two independent analog outputs (one for CO
and second for RH). Complete data from all
individual sensors are available via the RS485
serial line using the Modbus protocol. The
receiver also has a pair of relays with NO-C-
NC contact with the possibility of
independent setting of relay trigger level for
each monitored quantity by rotary selector.
Set of wireless sensors consists of at least one
or more battery powered wireless sensors
and one receiver.

Description
The receiver in connection with wireless sensors is
used to control ventilation and heat recovery units.
Based on the current air quality, the receiver then
efficiently controls the ventilation systems.
