Network Variable and Configuration Property Definitions
nciRefrigerant
Chiller refrigerant type, UNVT_refrig, level 1
This configuration property defines the type of refrigerant that the chiller uses. It will be
set when the LCI-C is bound into the UC800 controller. It is a read-only configuration
property that cannot be modified over LonTalk communications.
• Range: Range of enum values
• Default: Invalid (0xFF)
• UCPT reference: UCPT_refrig_type
nciSndHrtBt
Send heartbeat time, SNVT_time_sec, level 1
This is the maximum period of time that will expire before each bound heartbeated
network variable output will be automatically updated once. The configured minimum
send time (nciMinOutTm) is ignored. If nciSndHrtBt = 0x7FFF (6,553.5 s), which is the not
valid value, the controller will use the default value of 300 s for the send heartbeat time.
• Range: 0–6,553.4 s, 0 disables
• Default: 300 s (0x0BB8)
• SCPT reference: SCPTmaxSendTime (49)
