SDEH
Controlling dehumidification setpoint
COS: C5
Permissions: Read/Write
Query
Command
Syntax:
SN[#] SDEH?<CR>
Description: Requests the controlling dehumidification setpoint .
Assignment
Command
Syntax:
SN[#] SDEH=[value]<CR>
Description: Sets the controlling dehumidification setpoint to
[value]
.
Example:
SN1 SDEH=55<CR>
Response or
COS Message
Syntax:
SN[#] SDEH=[value]%<CR>
Example:
SN1 SDEH=55%<CR>
Node address 1 responds with a controlling dehumidification setpoint of 55% .
Parameters
Range
value:
humidistat setpoint in %RH
[10 – 90]
The controlling dehumidification setpoint corresponds to the active setpoint to which the humidistat is controlling the dehumidification
equipment . Assignment commands are ignored if the controller type is set to thermostat .
When the humidistat system mode is set to AUTO, the controlling mode is determined by the humidistat . In addition, when the humidistat
system mode is set to AUTO, the Humidification and Dehumidification setpoints are interdependent and must abide by the fixed deadband . If
an assignment command is received with a setpoint value that causes a deadband violation, the opposite setpoint is automatically increased
or decreased to fulfill the deadband requirement . If the deadband requirement cannot be fulfilled by increasing or decreasing the opposite
setpoint, the command is ignored and no response sent .
Integer values must be within the range specified . The dehumidification setpoint can be changed through the Home Screens for humidistat
control . If the dehumidification setpoint is changed at the thermostat, a C5 COS unsolicited message is issued (if C5 is ON) .
SDEH++, SDEH--
Increment or decrement the controlling humidistat dehumidification setpoint
COS: N/A
Permissions: Write only
Assignment
Command
Syntax:
SN[#] SDEH++=[value]%<CR>
Syntax:
SN[#] SDEH--=[value]%<CR>
Description: Increments or decrements the controlling dehumidification setpoint to
[value]
.
Examples:
SN1 SDEH++=3%<CR>
SN1 SDEH--=5%<CR>
Response
Syntax:
SN[#] SDEH++=[value]%<CR>
Syntax:
SN[#] SDEH--=[value]%<CR>
Example:
SN1 SDEH++=5%<CR>
Node address 1 responds with incrementing the dehumidification setpoint by 5% RH .
Parameters
Range
value:
controlling dehumidification setpoint increment or decrement value
The controlling dehumidification setpoint corresponds to the active setpoint to which the humidistat is controlling the dehumidification
equipment . This command is ignored if the controller type is set to thermostat .
When the humidistat system mode is set to AUTO, the controlling mode is determined by the humidistat . In addition, when the humidistat
system mode is set to AUTO, the Humidification and Dehumidification setpoints are interdependent and must abide by the fixed deadband .
If an assignment command is received with a setpoint increment or decrement value that causes a deadband violation, the opposite setpoint
is automatically increased or decreased to fulfill the deadband requirement . If the deadband requirement cannot be fulfilled by increasing or
decreasing the opposite setpoint, the command is ignored and no response sent .
If the resultant setpoint is outside the allowable range for the dehumidification setpoint, the command is ignored .
