Chemoclean function
Just like the timer function, Chemoclean can also be used to start a cleaning cycle.
However, Chemoclean also gives you the added option of defining various cleaning and
rinsing intervals and of dosing cleaning agent.
Therefore, it is possible to clean irregularly with different repeat cycles and to separately
set the cleaning times with post rinse times.
Please note the following:
To use the Chemoclean function the transmitter has to be equipped with a designated
relay board (see product structure or chapter "accessories").
The timer and Chemoclean are mutually dependent. While one of the two functions is
active, the other cannot be started.
For the Chemoclean function, the relays 3 (water) and 4 (cleaner) are used.
If the cleaning is prematurely aborted, a post rinse time always follows.
If the setting is "Economy", cleaning only takes place with water.
