SUN AND WIND SENSOR V1.l and SUN SENSOR SWITCH V4 by Draper Page 6 of 9
SUN assuming fixed levels
The sun sensor is capable of sending independent bus commands as a result of each of the 5 sunrise and sunset
events, and the thresholds may be adjusted individually. However, once this capability is enabled, the user selectable
"level" is disabled. The Sun Sensor Switch is simply a display of sun levels in this case.
Setting any sun event to a custom value (S+7+7 > C# > C1 or C2 > Cx . . . ) automatically turns off the users ability
to set the level. You can force the ASM to allow user selection using S+7+7 > C# > C10 > 04 > S, however,
operation may be strange.
Setting Sun Thresholds individually
S+7+7 > C# > C4 or C5 > Ow > Ox > Oy > Oz may still be used to set multiple thresholds at once; please see that
section above. The highest 5 (as though the user selected high level) are the values used in fixed mode.
To set a specific sun threshold you must enter the two-digit threshold after selecting the threshold to set. For
example, setting the medium sunrise threshold to 86 would be done with the following sequence: S+7+7 > C# > C4 >
C3 > 08 > 04
The following sequence must be completed to change any threshold:
1. Press 5+7+7 > C#, the GREEN programming LED must tight.
2. Press C4, the LED will blink off then GREEN, and you are setting sunrise thresholds (or press C5 for sunset).
3. Press C 1-5 to select which threshold to set, the LED will blink RED then GREEN.
4. Press 0 1 - I0 to select the 10's of percent for this threshold (0 10 select 01, the LED will blink RED then GREEN.
5. Press 0 1-1 0 to select the 1's of percent for this threshold, the LED will blink off and then be GREEN.
If bad numbers are entered, the LED will flash GREEN & RED a few times and then be GREEN and the original
thresholds are UNCHANGED; the accessory is still in program mode but must get a close command next.
Errors include:
-Entering a sunrise threshold smaller than the associated sunset.
-Entering a sunset threshold larger than the associated sunrise.
Programming any individual threshold automatically sets the "level" to high (default).
If you are not using the Sun Sensor Switch to change between the thresholds, then the thresholds as described under
"intermediate positions using default"' are the ones used.
After installation be sure to select a Sun Sensor Delay of at least 10 minutes.
Installing SUN AND WIND SENSOR using radio (RFTM): Step by Step
The SUN AND WIND SENSOR may be connected to an RFTM for wireless operation. However, the batteries on an
RFM will not power the SUN AND WIND SENSOR for very long, so a DCPM must also be used. The "change
radio address" may be used if more than one SUN AND WIND SENSOR is connected to a system using radio and
they happen to have the same address. Connect everything as shown:
This setup allows the SUN AND WIND SENSOR to convert BUS commands received on the Sun Sensor Switch
(DSK) port to radio commands. You must have a method of getting commands into the Sun Sensor Switch port to
program the SUN AND WIND SENSOR. This can be accomplished by temporarily plugging an eye in the Sun
Sensor Switch jack.
Using an IR only handheld transmitter, program the SUN AND WIND SENSOR to radio mode (S+7+7 > C# > C8 >
02).
Press the "learn" button on the RR that you want the SUN AND WIND SENSOR to talk to. Its LED must come on.
Quickly press a button on the IR transmitter aimed at the eye plugged into the SUN AND WIND SENSOR. (This
will cause the SUN AND WIND SENSOR to send a radio command that will be learned by the RR.) The LED on the
RR must go out when the button is pressed indicating the RR has learned the radio address of the SUN AND WIND
SENSOR.
