[Write, Raise and lower the heating and cooling setpoints from a single command point(volatile, reverts to ‘uncommanded’ after power outage).]

1:2 ECM Fan Ovrd

[Write, allows network direct control of the ECM blower speed (volatile, reverts to ‘uncommanded’ after power outage)]

1:3 AO2 Override

[Write, allows network direct control of the Analog Output 2, volatile, reverts to ‘uncommanded’ after power outage)]

1:4 Space temp Ovrd

[Write, allows the network to send space temperature values to the heat pump controller, volatile, these will supersede any temperature sensor connected to the space temperature Analog Input.]

Analog Value (Type 2)

2:1 Occupied Cool

[Write, Cooling setpoint in Occupied mode] 2:2 Unoccupied Cool

[Write, Cooling setpoint in Unoccupied mode] 2:3 Occupied Heat

[Write, Heating setpoint in Occupied mode] 2:4 Unoccupied Heat

[Write, Heating setpoint in Unoccupied mode] 2:5 Temporary Occ Time

[Write, set the duration of the temporary occupancy timer which is initiated by pressing the button on the zone sensor]

2:6 Remote Setpt Span

[Write, sets the offset range that the setpoint knob on the zone sensor may apply to the effective Htg/ Clg setpoints]

2:7 Remote Setpt Bias

[Write, biases the entire readjust range of the remote setpoint adjust to allow zeroing from the network.]

2:8 Space Temp Offset

[Write, Adds an offset to the Space Temp value for calibration]

2:9 Dehumidify Setpt

[Write, sets the humidity value that will cause the heat pump to enter passive dehumidification]

2:10 Low Temp Limit Adj

[Write, sets the water coil low temperature (freeze sensing) limit for shutdown]

Binary Input (Type 3)

3:1 Fan Cmd Status

[Read, show the commanded condition of the Fan Output,Inactive=Off, Active=On]

3:2 Comp Cmd Status

[Read, show the commanded condition of the Compressor Output, Inactive=Off, Active=On]

3:3 Comp Hi Capacity Cmd

[Read, show the commanded condition of the ‘Hi Capacity’ Compressor control, Inactive=Off, Active=On.]

3:4 Reversing Valve

[Read, show the commanded condition of the Reversing Valve Output, Inactive =Heating, Active =Cooling]

3:5 Accessory 1 Output

[Read, Shows the commanded value of the X1 (Accessory

3:8 Alarm Status

[Read, shows the in alarm/out of alarm status, Inactive=Off, Active=On]
