OH
Remote humidity
COS: C3
Permissions: Read only
Query
Command
Syntax:
SN[#] OH?<CR>
Description: Requests the remote humidity sensor reading .
Response or
COS Message
Syntax:
SN[#] OH=[value]%<CR>
Example:
SN1 OH=25%<CR>
Node address 1 responds with a remote humidity of 25% RH .
Parameters
Range
value:
humidity sensor value
[--, 0 – 99]
The remote humidity reading source is from Support Module 1, Sensor 2 configured as monitor . If a query command is received and Support
Module 1 is not connected or is temperature only, it responds with
SN[n] OH=--%<CR>
.
If the value of the remote humidity changes by 1% RH or more, a C3 COS unsolicited message is issued (if C3 is ON) .
bIHUM
Built-in humidity

Query
Command
Syntax:
SN[#] BIHUM?<CR>
Description: Requests the built-in humidity sensor reading .
Response
Syntax:
SN[#] BIHUM=[value]%<CR>
Example:
SN1 BIHUM=30%<CR>
Node address 1 responds with a built-in humidity of 30% RH .
Parameters
Range
value:
built-in humidity sensor value
[--, 0 – 99]
If the humidity sensor has an error, the response is
SN[n] BIHUM=--%<CR>
.
RTS

COS: N/A
Permissions: Read only
Query
Command
Syntax:
SN[#] RTS?<CR>
Description: Requests the node’s direct-wired remote temperature sensor (T1 and T2 terminals) reading .
Response
Syntax:
SN[#] RTS=[value][scale]<CR>
Example:
SN1 RTS=68F<CR>
Node address 1 responds with a remote temperature reading of 68°F .
Parameters

[0 – 40]
no sensor attached or error
[--]
scale:
temperature scale
[F, C]
F:
Fahrenheit
C:
