Example: Running, remote mode, ready, coolant temp 22.9°C, set-point 23.0°C, pump temp 17.0°C, 76.3%
cooling, Fan Speed 69.2%, tank level low = 119, status: running in remote mode within alarm range, faults: none

STAT1A
Bit Field Definition: convert decimal number sent into binary, read as follows:
|__ __ __ __ | __ __ __ __ | __ __ __ __ | __ __ __ __ |
| | | | | | | | | | | | | | | |___Chiller Running?
1 = RUNNING, 0 = STOPPED
| | | | | | | | | | | | | | |_____Remote or Local
1 = REMOTE, 0 = LOCAL
| | | | | | | | | | | | | |________Chiller Ready?
1 = READY, 0 = NOTREADY
| | | | | | | | | | | | |__________Temp low alarm
1 = Temp < SP - WIDTH
| | | | | | | | | | | |______________Temp high alarm
1 = Temp > SP + WIDTH
| | | | | | | | | | |_____________Chiller Heating or Cooling 1 = HEATING, 0 = COOLING
| | | | | | | | | |__________________System Warning
1 = WARNING, 0 = NONE
| | | | | | | | |_____________________System Alarm
1 = ALARM, 0 = NONE
|_______ rsvd ____| |__________________________ rsvd
The Warning bit is triggered by tank level low and a temperature outside of the +/- alarm width.
The Alarm bit is triggered by an RTD fault, a pump fault, or a fan fault.
