10.2 Production control via network
To control production via a network connection, configure the humidifier
using following parameters:
digital 27 , digital 37 and integer 6 0 ( Modbus 188)
When D37 is set to 1, the humidifier ignores the external control signals
(external controller or probes) and uses the value of integer 60 (Modbus
188) as the control signal. Humidity production can be managed in two
modes:
To manage production as a percentage:
• Set D 37 = 1;
• Set parameter A0 = 1 (Carel 20, Modbus 148, proportional mode);
• Set Carel integer variable 60 (Modbus 188) to the desired level (0-1000
= 0-100.0%).
To manage production with a humidity probe managed by the Main unit:
• Set D 37 = 1;
• Set parameter A0 = 2 (Carel 20, Modbus 148, humidity probe mode);
• Set Carel integer variable 60 (Modbus 188) to the desired level (0-1000
= 0-100.0 rH%);
• Set Carel integer variable 52 (Modbus 180) to the desired humidity set
point.
When D37 is set to 1, if communication is lost for the number of seconds
set by parameter C4, the “Main Offline” alarm is activated (see Alarm table)
and production stops.
Production can be activated/deactivated via digital parameter D27 (see
the Parameter table).
If D27 = 1 the humidifier is disabled and production stops
if D27 = 0 the humidifier is enabled and production is activated.
D27 is independent from the status of D37.
10.3 Washing cycle activation via network
A washing cycle can be performed at any time by managing digital
variable 38.
Setting the variable to 1 will immediately activate a washing cycle, even
if the unit is in standby, and even if both automatic washing and washing
due to inactivity are disabled by their corresponding parameters.
The variable will keep the value 1 throughout the duration of the washing
cycle, and will automatically be reset at the end of the cycle.
