4.8.11. Visualization
The parameter involved is:
• M190 ENABLE CONTROL OF SEQUENCING SYSTEM: pre-set = YES
The system may has only one user board for all the messages.
Each of them must give information about the source unit, so in the first line of the screen there is the origin displayed.
The standard screen is as the following one:
dd/mm/yy Uxx hh:mm
-----device-----
---information---
+++++++++++++
In the first line the “Uxx” indicates the number of the unit.
When the parameter M190 is set to YES, you can view the status of the system with the following two screens:
1)
U STS CP H VE FC HM
1 ON 1 0 50 50 50
2 OFF 0 0 0 0 0
3 SBY 0 0 0 0 0
2)
U STS CP H VE FC HM
4 --- 0 0 0 0 0
5 --- 0 0 0 0 0
L=x T=yy.y hh:mm:ss
These two screens gives the following information:
• U = unit: it indicates the number of the unit (1...5);
• STS = state: it indicates the state of the unit:
– ON: the unit is on
– OFF: the unit is off
– SBY: the unit is in stand-by. That’s means the unit is on but disabled.
– AL: the unit is in alarm state
– ERR: there’s a serial communication error with the unit
– - - - : there isn’t any unit connected;
• H = heater: it indicates the state of the compressor (1 -> ON; 0 -> OFF);
• CP = compressor: it indicates the state of the compressor (1 -> ON; 0 -> OFF);
• VE = evaporator fan : it indicates the state of the evaporator fan (ON -> 100%; XX -> XX%);
• FC = freecooling: it indicates the state of the freecooling (ON -> 100%; XX -> XX%);
• HM = humidifier: it indicates the state of the digital humidifier (1 -> ON; 0 -> OFF) or the analog humidifier (ON
-> 100%; XX -> XX%);
At the fourth line of the second screen it’s shown which unit is the leader, the internal temperature read by the leader
unit and the time remaining to the next rotation.
If M190 is set to sequencing with stand by management the next screen wil appear, where the running hour of each unit
is showed.
U STS Running hours
1 ON 10h
2 OFF 25h
3 SBY 30h
