Function
This device is designated for monitoring of parameters of environment (meaning temperature
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 account 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 allowed
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 uence on function
permanently ON or pemanently OFF.
To ensure correct installation, arrows on the product's housing need to be aiming upwards.
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.
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.
