Set Relay Parameter and Limits
Use the RSEL command to show or set the parameter that controls the
relay, and the limits that are applied.
RSEL [parameter lo_value hi_value]
where
parameter = Parameter that controls the relay. Available parameters
are:
RH relative humidity
T temperature
Tdf dew/frost point temperature
Td dew point temperature
Tw wetbulb temperature
h enthalpy
x mixing ratio
a absolute humidity
dTd dew/frost point depression
Disabled no parameter, relay disabled
lo_value = Low limit of relay activation.
hi_value = High limit of relay activation.
Example (show current settings):
>pass 9000
>rsel
Relay configuration : RH (88.00 ... 92.00 %)
Example (set temperature as relay parameter, low limit 25, high limit 30):
>rsel t 25 30
Relay configuration : T (25.00 ... 30.00 'C)
