Command Reply Description
CRHn &| Sets the hysteresis of the precipitation detection thresh-
old to n value.
The value should range within 0 and 20%.
If the 0.1% resolution is set, the value must be ex-
pressed in tenths (for example, write 20 to indicate
2.0%).
Default : 2 (=2% with 1% default resolution)
RRH & n| Reads the setting of the hysteresis of the precipitation
detection threshold.
CSTn &| Sets the reference temperature to discriminate between
rainfall and snowfall to n value expressed in tenths of °C.
The value should range within -50 (=-5 .0 °C) and 50
(=+5.0 °C).
Default : 20 (=+2.0 °C)
RST & n| Reads the setting of the reference temperature to
discriminate between rainfall and snowfall.
CSHn &| Sets the hysteresis of the reference temperature to
discriminate between rainfall and snowfall to n value
expressed in tenths of °C.
The value should range within -5 (=-0 ,5 °C) and 5
(=+0,5 °C).
Default : 5 (=+0,5 °C)
RSH & n| Reads the setting of the hysteresis of the reference
temperature to discriminate between rainfall and
snowfall.
CRADn &| Sets the delay in indicating the beginning of a precipita-
tion, both rainy and snowy, to n seconds (0…32767 s).
The indication of precipitation in progress is generated
only if the precipitation lasts longer than the set time.
Default : 0
RRAD & n| Reads the setting of the delay in indicating the beginning
a precipitation.
CRABn &| Sets the delay in indicating the end of a precipitation,
both rainy and snowy, to n seconds (0…32767 s).
The indication of precipitation in progress ceases only af-
ter the set time has elapsed from the end of the precipita-
tion.
Default : 120
RRAB & n| Reads the setting of the delay in indicating the end of a
precipitation.
CTADn &| Sets the delay in indicating the transition from rainfall to
snowfall, when the temperature dops below the reference
temperature, to n seconds (0…32767 s).
Default : 0
RTAD & n| Reads the setting of the delay in indicating the transition
from rainfall to snowfall, when the temperature dops be-
low the reference temperature.
