NOTES
If the Scale column has a value for a Data Description, divide the Modbus value by the value in the Scale column to get the scaled value.
Reference Document: ST100I&C PA Parameters and Events, Version 18.0
1. Timer mode: 0 = no, 1 = yes
2. Type of DT Room-Glycol: 0 = no, 1 = contact, 2 = value
3. Predictive Hum Control: 0 = relative, 1 = compensated, 2 = predictive
4. Temp Control Algorithm: 0 = proportional, 1 = PD, 2 = PDI; 3 = intelligent
5. When VFD is set to manual mode (coil 22), the host can control the VFD by the value of register 40019. The Manual VSD
Timer will start to count down. Once it reaches 0, the VFD control mode will switch to auto. The host will need to periodically
reset this timer in order to maintain the manual mode. Consult factory for BMS timer information.
6. Operating state:
Bit 0-1: 00 unit off, 01 unit on, 10 unit standby
Bit 2-3: 00 auto, 01 manual
Bit 4-7: 0000 none
0001 local user
0010 alarm
0011 schedule
0100 remote user
0101 external device
0110 local display
7. Alarm state bit map:
Bit 0 = Reset state
Bit 1 = Active state
Bit 2 = Acknowledge state
Bit 3-7 = Alarm Type
00000: Message
00001: Warning
00010: Alarm
8. Free-cool state: 0 = Off, 1 = Start, 2 = On
