10.4 Read-only parameters
Parameter UOM range def note
d0 Th probe temperature reading °C/°F 0-1000 0
d1 Th probe humidity reading %rH 0-1000 0
d2 Configurable input reading (optional card) % / %rH 0-100 0
d3 Tank operating hour counter (resettable, see "Reset
hour counter from display") h 0-9999(*) 0
d4 Unit hour counter (read-only) h 0-9999(*) 0
d5 Instant production % 0...100 0
d6 Time remaining to end of piezoelectric transducer life h 0...9999(*) 9999 equal to AF - piezoelectric transducer hour counter
d7 Manage secondary unit production - 0...1 0 R/W parameter:
0 = the secondary exactly replicates the production of the main, as it depends
on the setting of parameter P0 on the main;
1 = the secondary produces according to the request sent by the main and its
own P0 setting; it is not affected by the setting of P0 on the main
d8 Dew point temperature °C/°F 0…1000 0 calculated using d0 and d1
Tab. 10.e
(*) after 999 the display shows to indicate the 1000s (the three digits are displayed with a dot at the top between the first and second digit).
11. HUMIDIFIER CONTROL VIA NETWORK
The variables shown in the list are a set of all the internal variables. DO NOT CONFIGURE ANY VARIABLES THAT ARE NOT SHOWN IN THE TABLE, OTHERWISE
HUMIDIFIER OPERATION MAY BE AFFECTED.
The serial connection (M11) is configured by default with the following parameters:
- Address 1
- Baud rate 19200 bps
- Frame 8,N,2
(not modifiable)
NOTICE:
it is recommended to set on the supervisor (main) the maximum waiting time for a response from humiSonic - after being queried by the supervisor - of
at least 500 ms.
