valve removal – this option is used to remove the valve from the controller 
memory. Valve removal is used  e.g.  at disassembling the valve or  module 
replacement (re-registration of a new module is necessary)

nformation on how to set those parameters which have not been described in detail  
above, may be found in section Valve 1,2 and 3. 

IV.f)Internet module

Note:   This   type   of   control   is   available   only   after   purchasing   and   connecting   an  
additional   controlling   module   ST-500   which   is   not     included   in   the   standard  
controller set.

Internet module is a device enabling the user remote control of the CH boiler 

via   the   Internet   or   local   network   .   The   user   controls   the   status   of   all   Ch   boiler 
system devices on the home computer screen and the operation of each device is 
presented in the form of animation. 

Apart from the possibility to view the temperature of every sensor, the user 

can change the set temperatures for both the pumps and the mixing valves.

After   switching   the   module   on   and   selecting   DHCP   option,   the   controller 

automatically downloads such parameters as IP address, IP mask, gateway address 
and DNS address from the local network. If any problems arise when downloading 
the   network   parameters,   they   may   be  set   manually.   The  procedure   of   obtaining 
these  parameters is described in detail in the instruction  manual of  the Internet 
Module. 

Module password reset function may be used when the user has changed the 

default password on the login page. If the user's new password is lost, the default 
password may be restored by resetting the module password. 

IV.g) GSM module

Note:   This   type   of   control   is   available   only   after   purchasing   and   connecting   an  
additional controlling module ST-65 which is not  included in the standard controller  
set.
