R s16 1 This indicates the time remaining days before the ECC
sensor must be calibrated or replaced. Calibration

R u8 1
R f32 2 The voltage supplied to the device at the nominal 24.0
volt input, in millivolts.
R u16 1 Gas calibration interval in days
R u8 1 For example:
If A1:rising/A2:rising -> 0x11, 0b00010001
If A1:rising/A2:falling -> 0x21 0b00100001
R u8 1 For example:
Relay1 to Alarm 1 (01)
Relay2 to Alarm 2 (10)
Initial relay1 status to De-energized (0)
Initial relay2 status to Energized (1)
Then, the bits are 0b00101001, which is 0x29
R u16 1 Delay between allocated trigger occuring and actual
relay activation
