DB1.7…DB1.0 = 0x89 = 137: Internal temperature = 40*DB.1/255 = 40*137/255 = 21,5 °C
DB0.7…DB0.0 = 0x08: Data telegram
Radio protocol from Controller/Gateway
to MVA valve actuator
VALVE POS: Example in HEX "0x05770008"
DB3.7…DB3.0 = 0x05 = 5: new valve position is 5%
DB2.7…DB2.0 = 0x77 = 119: room temperature = 255 - 119 = 136 => 40 * 136 / 255 = 21,33
°C
DB1.7…DB1.0 = 0x00:
o
DB1.3 = 0: Regular default radio cycle (no summer mode)
o
DB1.2 = 0: DB3.7…DB3.0 is set to valve position %
DB0.7…DB0.0 = 0x08: Data telegram
SET_TEMP: Example in HEX "0x80810408"
DB3.7…DB3.0 = 0x80 = 128: Setpoint temperature is 40 * 128 / 255 = 20,1°C (*1)
DB2.7…DB2.0 = 0x81 = 129: room temperature = 255 - 129 = 126 => 40 * 126 / 255 = 19,8
°C
DB1.7…DB1.0 = 0x04:
o
DB1.3 = 0: regular default radio cycle (no summer mode)
o
DB1.2 = 1: DB3.7…DB3.0 is set to internal temp.-controller with default duty cycle
(Summer bit not active)
DB0.7…DB0.0 = 0x08: Data telegram
(*1) Setpoint temperature 20,1°C is internally stored for use with radio loss situations (safety mode).
