Q7300H COMMUNICATING SUBBASE SYSTEM INTEGRATION USER ADDRESS MANUAL
User Address
tMaxHtStg Maximum number of heating stages allowed by the subbase.
tNextOcc Occupancy state called for next by the thermostat time-of-day schedule. Occ, UnOcc, Null.
tOCool Equipment output relay
tOff User Mode Switch–Off setting. True= selected; False= not selected.
NOTE:
tOKrdwrStPts Future use.
tPgmVer Each thermostat program code version has a PgmVerCode. Each subbase code version is only compatible
with the tPgmVer specifically designed for subbase compatibility. The subbase reads the tPgmVer and checks
for compatibility. If the subbase is not compatible, a tPgmVerAlrm is generated and the Q7300 no longer
communicates with the subbase. If the subbase is compatible, the subbase uses tPgmVer to change its
functionality to be compatible with the software version of the thermostat. The only tPgmVer currently
recognized is 0.
tPump Equipment output relay
tReHum Equipment output relay
tSubBaseId Future use.
tSystemState The thermostat internal system state flag. Some of the values are listed in hexadecimal:
tTAT Equipment output relay
tTmpSetPt A temporary setpoint is displayed and used by the thermostat; True = Yes, False = No.
