Use
– Check
Enable
for each sensor that you want to include in the
combination algorithm used to determine the output value.
D:
R:
Enabled index (1)
checked or unchecked
Calibration
– If needed, enter a
Calculated Value
by adding the
Calibration
to the
Raw Value
for each ZS or wireless sensor.
D: 0 to 10
Combination Algorithm –
If using more than one ZS or wireless sensor, select
how the enabled sensors' values are to be combined to determine the output
value. When the calculation is performed, only sensors with a valid value will
be included.

Input Smoothing
– If the raw value from the sensor changes frequently, you
can select one of the following options to send out an average of several
readings on the output wire.
None
- The raw value
Minimum
- The average of the last 2 readings
Medium
- The average of the last 5 readings
Maximum
- The average of the last 9 readings

Show on sensors
– Select
Local Value
to have each enabled sensor display its
individual sensed value, or
Calculated Value
to have each sensor display the
value determined by the
Combination Algorithm
.

Display Resolution
– Defines the resolution of the value to be displayed on the
sensor. For example, 1 displays only integers (e.g., 74) and 0.5 displays values
to the nearest 0.5 (e.g., 74.5).

COV Increment
– To reduce Rnet traffic, you can force the microblock to
update its output only when the sensed value changes by more than the COV
Increment.

Occupancy Contact State –
The current hardware state of the controller's
REMOTE
input.
R:
Open/Closed
Sensor Invalid
– This internal input monitors the communication between the controller
and the SPT sensor.
Off
indicates communication is normal.
R:
Off/On
Rnet Sensed Occupancy
– Displays occupancy status detected by wireless infrared
motion sensor.
R:
Off/On
Hot Water Valve
- The current value of the controller's
HWV/ACT
output.
R:
0 to 100%
Heating Stage 1
- The current hardware state of the controller's
HEAT1
output.
R:
Off/On
Heating Stage 2
- The current hardware state of the controller's
HEAT2
output.
R:
Off/On
Fan S/S or EH 3
- The current hardware state of the controller’s
FAN/HEAT3
output.
The function of this output depends on the terminal type.
R:
Off/On
