Total fault message

WHF00 WARM HOLDING FUNCTION is a local option for each station.

NAC00 RECHARGING PRIMARY is a central option. It is activated and

installed on one device in the cascade and applies centrally to all

devices in the cascade.

The parameters for thermal disinfection are set at the master. The

corresponding info messages are also specified at the master. With

regard to a fixed command station (cascade mode = 0) with a local

circulation pump, the zone valves of the slave stations remain closed

and are therefore not disinfected. If the circulation pump is central

(KAS07 = 1), all zone valves are opened for disinfection to enable flow

through the entire installation.

The total fault message output is non-floating (relay L5 (Error): 230V

AC). The total fault message is triggered as soon as an error occurs in

the controller. In order to identify the error in question, it is necessary

to check the controller display. The logic of the relay switching can

be defined with the parameter KOM03. The total fault message is a

local function. With regard to cascade operation, each station needs

to be connected individually as slave stations do not relay their error

messages to the master.
