Data protocol with integrity check


Each Digistat RF Transmitter is given one of 4096signal security codes at manufacture which prevents2 or more Digistats in one dwelling interfering witheach other.

When the system is commissioned the transmittersends out its security code as a “Learn” signal to thereceiver, which from then on will only respond to thatsecurity code signal.

The system can be taught a new code if either thetransmitter or receiver needs replacing by simplyre-commissioning.



CommissioningCommissioningThe Learn procedure is :

• Press buttons to enter ‘learn’ mode

• Red and Green LED’s should be on

• Power up the transmitter

• Red LED should ‘flash’ for 7 secondsthen go out

To check that the system isfunctioning correctly, increase the settemperature on the Digistat until theflame appears, the red LED should‘flash’ for 7 seconds then go out & thegreen LED come on
