Dip Switches: SED-T series stats come directly from production with all dip switches set to 0. The dip switches settings must be changed otherwise the device will not send any telegrams.
Example on how to use the dip switches:
If the dip switches are set to 1= OFF, 2 = ON, 3 = ON, 4 = OFF, the stat would wake up every 10 seconds and take a look at the values. if they changed, the stat will send a new telegram with the new value. if the value did not change however, the stat will go back to sleep until the next 10 seconds elapse (first iteration). If the value did still did not change before the 7th iteration, then the stat will randomly send a telegram with the unchanged value at any time between the 7th and the 14th iteration. that is a minimum of 10*7 = 70 seconds and maximum of 10*14 = 140 seconds.
Solar cell: When removing the unit from the box for the first time, its energy banks (super capacitor) need to be charged using one of the methods below in order to be able to learn the device. A minimum of 2.1VDC is required before the stat can wake up and send a telegram and Ideally, the Super cap voltage should be between 4 to 5Volts.
Method 1: Power the sensor with 24VAC for 1 hour (3volts/hour)
Method 2: expose the solar cell to light for x amount of time depending on the light source:
1- Room with LED panels: 24hr minimum charging time (0.1Volts/hour)
2- Lit room with day light: 3-4 hours minimum charging time (0.7Volts/hour)
3- Direct sunlight: 1/2 hour minimum charging time (3.5Volts/hour)
Battery: The 20mm coin cell battery does not charge the super capacitor, however it slows down the depletion of super capacitor once its charge drops below 2.1Volts.
