Turn Off
Threshold for
relay
deactivation
0-100.00%
(default:
depends on
source
selection)
Based on full scale range of the selected sensor, set the
value below which the relay will de-activate. For
example, to deactivate relay when CO
2
setting reaches
790, set this threshold value to 7.90%.

selection
N.O. (default),
N.C.
A N.O. (normally open) relay will be in the open state
until it is activated, i.e., turn-on threshold is met, at
which time it will close. A N.C. (normally closed) relay
will be in the closed state until it is activated, at which
time it will open.
Relay
Settings >
Min On
Min on time
1-240s
(default: 3s)
When relay activates, it will not deactivate until this
time has lapsed, regardless of the turn-off setting. The
relay will deactivate only when this time has expired
AND the turn-off threshold is met.
Relay
Settings >
Min Off
Min off time
1-240s
(default: 3s)
When relay de-activates, it will not activate again until
this time has lapsed, regardless of the turn-on setting.
The relay will re-activate only when this time has
expired AND the turn-on threshold is met.

Sensitivity
Adjust
sensitivity of PIR
motion sensor
0-100
(default: 80)
Sensor sensitivity can be adjusted from 0-100. The
default of 80 achieves the specified distance and
degree. If nuisance triggers occur or a further sensing
distance is required, this value can be decreased and
increased accordingly. See Figure 3 for a visual
representation of this sensitivity value.

Occupied
Delay
Time PIR stays
active after
event
1-120 min
(default: 10
min)
This is the number of minutes the occupancy state
will remain active after each motion event is
detected. This applies to the “occupancy” BACnet
and Modbus point as well as the output relay state,
if set to PIR in
Relay Settings.
