ETTING THE WATER HEATER ADDRESS
The managing water heater of the cascade system is connected to the AL-BUS connection on terminals 20-21
This connection also provides the power for the communication bus. The depending water heaters are all parallel
connected to the managing water heater communication bus.
The bus power is provided by the managing water heater on termi-
nals 20-21, switch S1 must be set in the OFF position (all controls).

ETTING OF THE CASCADE PARAMETERS
1. Enter the main menu by pushing the menu button
now select settings by toggling the up and down
arrow and enter settings by pushing the enter but-
ton.
3. Select the
Module Cascade Settings
and
NOT Boiler Cascade Settings
2. Now select Boiler Settings and enter the right pass-
word to continue.
4. Change burner address into Managing (Master) or
Dependent
with the correct sequence number.
( Dep2 is the first depending boiler e.g.)
Changes in parameter may only be carried out by a skilled commissioning/service
engineer, who has had specific training for setting up the HW range water heaters.
He will be able to check whether the installation functions correctly after the parame-
ter change has been done.
Parameters for cascade operation are found in the
Module cascade settings
menu,
located in the Water heater settings menu.
Parameters in the
Boiler heater cascade settings
menu should
NOT
be used.
Address rules
The cascade managing ad
dress (parameter 184) must be set to ‘Managing’ on the managing water heater.
The cascade depending addresses (parameter 184) must be set in a logical numbered order from 1= Dep. 2,
2= Dep. 3 etc. on the depending water heaters.
The total number of water heaters in the cascade must be stored in parameter 147 on the managing water
heater.
When the number of water heaters is set to 4, the first three depending controls are expected to be available
for the cascade. In this case depending controls 2, 3 and 4 must be selected. When any of these 3 are not
present on the communication bus the managing control detects the loss of a depending control and generates
the warning: Comm. Lost with module.
