Active = BACnet BMS control applies, inactive = standard hardwired
BMS control (next 5 entries are ignored)
Active = cooler run
Active = indirect cooling (no
Both inactive = vent operation
added water vapour)
Active = direct cooling (adds
water vapour - applies to
supercool only)
from 0 to predetermined maximum
Inactive > active = invokes tank drain
Cooler continues to run but with reduced performance
Inactive > active = reset these warning errors - can be done anytime
Also resets fan motor critical error generated in the case of one only
supply fan motor error and / or one only exhaust fan motor error
Cooler will be in forced vent or forced shutdown mode (in line with
settings)
Inactive > active = reset these critical errors - only successful with
control mode in the "off" position
For convenience this action also resets the warning errors outlined
above
PLC clock - analogue values 9 through
of year number)

"RTC set" is active

Active = able to adjust time analogue values 9 through 15, active >
inactive = load adjusted time into PLC clock (inactive = normal ongoing
setting)
Active = client has written
BACnet
active to this object since the
"COMS" flag
last PLC inactive write
on settings
screen (as set
during CW-80
commissioning)
This BACnet object is provided to
confirm integrity of the current BACnet
communications
Client must write active to this object at
least once every 30 minutes to maintain
BACnet control of this cooler
Otherwise cooler will adopt hard wired
BMS control due to loss of BACnet
communications
In the event of no signals present at
these hard wired terminals, the above
will result in cooler shut Down
