Description and Utilization
TAR2 actuator is wireless switching unit of a system (wireless relay) which allows direct switching low
power input load or switching control signals of high power relay which can then switch even very high
power inputs. The actuator is equipped with memory relay which minimizes consumption because the relay
only consumes current during switching pulse at the duration of 10 msec. This allows supplying the unit
from a replaceable lithium battery with an estimated life longer than 2 years of operation.
Attention! For setting and controling of the Actuator it is essential to have wireless Central Unit in
system, see
http://www.tesla.cz/en/tera-centrala/
. The Central Unit is not included with package of
TAR2 and it is sold and delivered extra.
Setting and configuration of TAR2 Wireless Actuator and whole system is also managed by connected
computer to Cenral Unit and TERAview application on PC.
TERAview application, drivers and user manual with detail configuration description is free downloaded on

TAR2 Wireless Actuator can be used in this system:
TERA System for Regulating Radon Concentrations (Figure 1)
Regulating system diagram description - Radon measuring probes located in a building transmit their
current radon concentration values to central unit wirelessly. The central unit analyzes this information and
on the basis of measured (set) concentration level value it sends wireless command to actuator which is
hardwired with power relay. Power relay switches on a fan which decreases radon concentration within an
area. After decreasing of radon concentration, the actuator receives a command to switch off the fan. This
cycle repeats depending on an increasing or decreasing volume activity of radon a building.
