SAFETY

 

 

Before using the device for the first time the user should read the following regulations carefully. Not obeying the rules 

included in this manual may lead to personal injuries or controller damage. The user’s manual should be stored in a safe 

place for further reference. In order to avoid accidents and errors it should be ensured that every person using the device 
has familiarized themselves with the principle of operation as well as security functions of the controller. If the device is 
to be sold or put in a different place, make sure that the u

ser’s manual is there with the device so that any potential user 

has access to essential information about the device.  

The manufacturer does not accept responsibility for any injuries or damage resulting from negligence; therefore, users 
are obliged to take the necessary safety measures listed in this manual to protect their lives and property. 

 

  

WARNING

 

 

High voltage! 

Make sure the regulator is disconnected from the mains before performing any activities involving 

the power supply (plugging cables, installing the device etc.). 

 

The device should be installed by a qualified electrician. 

 

Before starting the controller, the user shoud measure earthing resistance of the electric motors as well as the 
insulation resistance of the cables. 

 

The regulator should not be operated by children. 
 

NOTE 

 

The device may be damaged if struck by a lightning. Make sure the plug is disconnected from the power supply 
during storm. 

 

Any use other than specified by the manufacturer is forbidden. 

 

Before  and  during the  heating  season,  the  controller  should  be  checked  for  condition of  its  cables.  The  user 
should also check if the controller is properly mounted and clean it if dusty or dirty. 
 

 
 

Changes  in  the  merchandise  described  in  the  manual  may  have  been  introduced  subsequent  to  its  completion  on 
16.03.2022.  The  manufacturer  retains  the  right  to  introduce  changes  to  the  structure.  The  illustrations  may  include 
additional equipment. Print technology may result in differences in colours shown. 

 

 

 Care for the natural environment is our priority. Being aware of the fact that we manufacture 
electronic devices obligates us to dispose of used elements and electronic equipment in a 
manner which is safe for nature. As a result, the company has received a registry number 
assigned by the Main Inspector of Environmental Protection. The symbol of a  crossed out 
rubbish bin on a product means that the product must not be thrown out to ordinary waste 
bins. By segregating waste intended for recycling, we help protect the natural environment. 
It  is  the  user's  responsibility  to  transfer  waste  electrical  and  electronic  equipment  to  the 
selected  collection  point  for  recycling  of  waste  generated  from  electronic  and  electrical 
equipment.
