Control Modes - LEGRAND Wattstopper FSP-212D Instructions D'installation

The FSP-212D has five selectable modes, each of which has preset parameter settings. Once
the mode is selected, you have the ability to further customize operation by adjusting the Set
and the Time rotary trimpots.
Select the Mode and adjust the other rotary trimpots using a small screwdriver.
NOTE: A sixth mode, Test mode, is accessed automatically when mode A is selected. See
page 5 for details.
Set – This rotary trimpot is used to adjust three different parameters, depending on the current
mode: Desired Light Level (in foot candles), Hold Off Setpoint, and High Trim.
• The FSP-212D has a photocell which measures the ambient light continuously. In
Modes B, C, and D, this trimpot will adjust the Desired Light Level, with a range from
0 footcandles to 200 footcandles, and the FSP-212D will then adjust the dimming of the
load so that the combined amount of ambient light and electric light reaches the desired
light level. When this trimpot is set to the minimum position, the daylight control is disabled
and the FSP-212D will adjust the light level based only on occupancy without regard to
ambient light.
• In Mode A, this trimpot determines the light level for the Hold Off Setpoint, with a range from 0 footcandles to 200 footcandles.
When set to the minimum position, the light level hold off set-point is disabled.
• In Mode E, this trimpot controls the current dimming level, allowing visual confirmation of the High Trim level. The high trim level
is used to calculate the low dim amount, which varies based on the mode, as described below. It also determines the maximum
lighting level in Mode A, and if the photocell is disabled, determines the maximum lighting level for Modes B, C, and D.
Time – This rotary trimpot sets the amount of time delay after occupancy is no longer detected before the loads go to the Low Trim
value. Additionally, for Modes A and B, this controls the amount of time before the load goes from the Low Trim to OFF. The time will
be half of the initial delay. For example, if time is set to 20 minutes, the load will go from ON to the Low Trim level 20 minutes after
occupancy is no longer detected. The the load will then turn OFF 10 minutes after it goes to the Low Trim level.
Fade Time – Fade times for each mode can be found in the following chart. Note that fade up time in modes B, C, and D is dependent upon
the position of the Set trimpot.

Mode A – High/Low/Off Dimming for Indoor Parking Structure or High-Bay
Features: Transition between High, Low, and Off levels; Adjustable Hold Off Setpoint;
High trim and low dim levels are variable
This mode has a hold off light level set point, which can be adjusted to the desired light level
using Set trimpot, or disabled (when the Set trimpot is turned to the minimum setting).
Anytime occupancy is detected with ambient light level below the hold off set point, the load
turns ON (ramping up to the High trim level).
NOTE: In this mode, since there is no daylighting control, the High Trim level will be the
maximum amount of light for the load. (The High Trim level is set in Mode E.)
Once no occupancy is detected and the time delay expires, the load will fade down to the Low
Dim level which is 10% of High Trim level. As long as the area remains unoccupied, the load
stays at the Low Dim level for half the amount of the time delay, and then load turns OFF.
When the hold off light level set point is enabled using the Set trimpot, once the Load turns
OFF, after 5 seconds if the ambient light level is more than the set point value, the load will
stay OFF even if occupancy is detected. But if occupancy is detected within the 5 seconds, the load will return to the High Trim value,
even if the ambient light level is more than the hold off level.
NOTE: When you select mode A, The FSP-212D will initially enter Test mode and stay in test mode for 5 minutes, after which it will
switch to mode A operation. (Test Mode is identical mode to A, with the exception of Time Delay, which is fixed at 5 seconds.)
