ENVISION CONSOLE INSTALLATION MANUAL

BACnet Variables

Envision Console Controls

The variables will be listed with the point type and instance
preceding the variable name.

Analog Input (Type 0)

0:1

Space Temp

[Read only, shows the space temperature]

0:2

Discharge Air Temp

[Read only, field mounted sensor unless supplied

as a factory special]

0:3

Effective Clg Setpt

[Read only, shows the active cooling setpoint]

0:4

Effective Htg Setpt

[Read only, shows the active heating setpoint]

0:5

Space Humidity

[Read]

0:6

Water Coil Temp

[Read, shows the refrigerant temperature at its

coldest, for predictive freeze condition detection]

0:7

Low Temp Limit

[Read, shows the water coil low temperature (freeze

sensing) limit that will result in unit shutdown.]

0:8

ECM Cmd Output

[Read, shows the commanded speed (0-100%) of

the ECM Blower]

0:9

Alarms Enumerated

[Read only, 0=no alarms, 1=condensate alarm,

2=Compressor Hi Discharge Pressure alarm,

3=Compressor low Suction Pressure alarm,

4=Freeze sensing alarm, 8=Faulty Freeze

Sensor

alarm, 9=Loss of Charge]

0:10 AO2 Value

[Read, shows the output value (0-100%) of AO2]

Analog Output (Type 1)

1:1

Space Setpoint

[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]
