The network variables will be listed by point type:instance
convention. 2:1 would mean point type 2, point instance 1.
All volatile points will revert to the uncommanded values
after a power interruption.
Analog Input (Type 0)
0:1 Space Temp
[Read, shows the sensor value connected to
terminals RS and AIC on the terminal board]
0:2 Disch Air Temp
[Read, shows sensor value connected to AI4 on
the
FX10]
0:3 Freez Temp 1
[Read, shows the water coil heat exchanger
temperature For circuit 1.]
0:4 Freez Temp 2
[Read, shows the water coil heat exchanger
temperature For circuit2.]
0:5 Active Clg Setpt
[Read, shows the active cooling setpoint value]
0:6 Active Htg Setpt
[Read, shows the active heating setpoint value]
0:7 Freez Temp Limit
[Read, shows the low temperature limit of the
water coil heat exchanger.]
0:8 nvoAlarms
[Read, shows the current alarm status of the heat
pump, 0=No alarms, 1=Condensate detected,
2=Compressor 1 Hi Discharge Pressure,
3=Compressor 1 Low Suction Pressure, 4=Circuit
1 Low Temp Limit on Coax, 5= Compressor 2 Hi
Discharge Pressure, 6= Compressor 1 Low
Suction Pressure, 7= Circuit 1 Low Temp Limit
on Coax, 8=Circuit 1 Bad Refrigerant Temp Sensor,
9= Circuit 2 Bad Refrigerant Temp Sensor]
0:9 Economizer Temp
[Read, Shows the source water temperature for
Economizer operation.(effective on units released
after
8/11/07]
Analog Output (Type 1)
1:1 Common
Setpoint
[Write, Adjust the midpoint value between Active
Clg Setpt and Active Htg Setpt, raises and lowers
both from a single command.]
1:2 Space Temp Ovrd
[Write, Override the space temperature.]
Analog Value (Type 2)
2:1 Occupied
Cool
[Read/Write, Occupied cooling setpoint,
nonvolatile]
2:3 Occupied Heat
[Read/Write, Occupied heating setpoint,
nonvolatile]
2:2 Unoccupied Cool
[Read/Write, Unoccupied cooling setpoint,
nonvolatile]
2:4 Unoccupied Heat
[Read/Write, Unoccupied heating setpoint,
nonvolatile] Shutdown with antifreeze,
nonvolatile.]
2:5 Economizer Setpt
[Read/Write, adjust the temperature threshold for
economizer operation.]
2:6 Max Htg Setpt
[Read/Write, The upper limit that the heating
setpoint may be adjusted to.]
2:7 Min Clg Setpt
[Read/Write, The lower limit that the cooling
setpoint may be adjusted to.]
2:8 Remote Setpt Max
[Read/Write, Sets the upper value for the remote
setpoint adjust. A 2 setting gives you + 2 degrees
maximum.]
2:9 Remote Setpt Min
[Read/Write, Sets the lower value for the remote
setpoint adjust. A 2 setting gives you - 2 degrees
maximum.]
2:10 Zone Temp Offset
[Read/Write, This value is added to the sensor
value for For zone temp, and the sum is shown
on the Space Temp Variable. This is used for
calibrating the Space Temperature, nonvolatile.]
2:11 Economizer TempOffset
[Read/Write, This value is used for calibrating the
Economizer water temperature.]
Binary Input (Type 3)
3:1 Blower Cmd Status
[Read, shows the commanded status of the blower.]
3:2 Comp1 Cmd Status
[Read, shows the commanded status of
compressor
1]
3:3 Comp2 Cmd Status
[Read, shows the commanded status of
compressor
2]
3:4 Rev Valve Status
[Read, shows the reversing valve position,
inactive = heating, active = cooling.]
3:5 BO-5 ElectHeat
[Read, shows command status of BO-5 for
electric
heat]
3:6 BO9 Spare
[Read, shows command status of BO-9]
