Warning
Device is constructed for connection for 1-phase main alternating -current voltage and
must be installed according to norms valid in existing state. Connection according to
the details in this direction. Installation, connection, setting and servicing should be
installed by qualifi ed electrician staff only, who learn this instruction and functions
of device. For right device protection should be fronted-end certain element. Before
installation the main switch must be in position "OFF" and the device should be de-
energized. Don´t install the device to sources of excessive electro-magnetic interference.
By correct installation ensure ideal air circulation so in case of permanent operation and
higher ambient temperature the maximal operating temperature of the device is not
exceeded. For installation and setting use screw-driver cca 2 mm. The device is fully-
electronic - installation should be carried out according to this fact. Non-problematic
function depends also on the way of transportation, storing and handling. In case of any
signs of destruction, deformation, non-function or missing part, don´t install and claim
at your seller. After its lifetime it is possibe to dismount it, recycle, or store at protected
waste dump.

Function
This device is designated for monitoring of parameters of environment (meaning tem-
perature and relative humidity) in switchboards. It enables setting of eight conditions
of constact closing and therefore it is usable for various types of load (e.g. fans, heating,
air-conditioning, dehydrating units,..). While installing it is neccessary to take into ac-
count the fact that hysterisis rises by persistence of measured values between sensor
and ambient environment.
The device is equipped by sensor fault detection. In case of sensor falut, exceeding al-
lowed limits (for temperature -30 °C/-22 °F and 80 °C/176 °F; for humidity 5 % and 95 %)
or in case of faulty internal communcation higher than 50 % (due to e.g. high ambient
disturbances) contact opens and sensor fault i indicated. Sensor fault doesn´t have infl u-
ence on function permanently ON or pemanently OFF.
To ensure correct installation, arrows on the product's housing need to be aiming up-
wards. Ventilation openings must not be covered.
Choice of function / Relay switched under the following conditions:
A: T > Tset or RH > RHset
Relay switches if temperature or humidity exceeds set limits, relay opens if temperature
and humidity is under set limit; e.g. fan switching, fault indication.
B: T < Tset or RH > RHset
Relay switches if temperature is lower or humidity higher than selected limit, relay
opens if temperature is higher or humidity lower than selected limit; e.g. switching
heating unit.
C: T > Tset or RH < RHset
Relay switches if temperature is higher or humidity lower than selected limit, relay
opens if temperature is lower and humidity higher than selected limit; e.g. switching
of cooling unit with moistening.
D: T < Tset or RH < RHset
Relay switches if temperature or humidity are smaller than selected limit, relay opens if
temperature and humidity is higher than selected limit, e.g. fault indication, switching
of heating unit with moistening.
E: T < Tset and RH < RHset
Relay opens if temperature or humidity are higher than selected limit, relay switches
if temperature and humidity drops under selected limit, inverse function to function
A (NC contact).
F: T > Tset and RH < RHset
Relay opens if temperature is lower or humidity higher than selected limit, relay
switches if temperature is higher and humidity lower than selected limit, inverse
function to function C (NC contacts).
G: T < Tset and RH > RHset
Relay opens if temperature is higher or humidity lower than selected limit, relay
switches if temperature is lower and humidity higher than selected limit, inverse
function to function C (NC contact).
H: T > Tset and RH > RHset
Relay opens if temperature or humidity are lower than selected limit, relay opens if
temperature or humidity are higher than selected limit, inverse function to function
D (NC contact).
ON: Manual relay control - relay is always permanently switched (connection test).
OFF: Manual relay control - relay is always permanently open (temporarily out of order).
Note: In case the conditions for switching are not applied, relay is open.
