Assignment
Command
Syntax:
SN[#] SP++=[value]<CR>
Syntax:
SN[#] SP--=[value]<CR>
Description: Increments or decrements the active controlling setpoint by
[value]
.
Examples:
SN1 SP++=1<CR>
SN1 SP--=5<CR>
Response
Syntax:
SN[#] S[sp]++=[value][scale]<CR>
Syntax:
SN[#] S[sp]--=[value][scale]<CR>
Example:
SN1 SH++=5F<CR>
Node address 1 responds with incrementing the heat setpoint by 5°F .
SN1 SC--=2C<CR>
Node address 1 responds with decrementing the cool setpoint by 2°C .
SN1 SHUM++=5%<CR>
Node address 1 responds with incrementing the humidification setpoint by 5% RH .
SN1 SDEH--=5%<CR>
Node address 1 responds with decrementing the dehumidification setpoint by 5% RH .

The active controlling setpoint corresponds to the active setpoint to which the control is controlling the equipment .
When the system mode is set to AUTO, the controlling mode is determined by the control . In addition, when the control system mode is set
to AUTO, the heat and cool setpoints or humidification and dehumidification setpoints are interdependent and must abide by the 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 an assignment command is received while the thermostat is running the program schedule, the thermostat automatically initiates a
temporary hold with an end time of the start time of the next scheduled event . If a hold is active at the time of the assignment command,
the hold setpoint is modified . In addition, if a hold is initiated as a result of the receipt of this command, a C17 COS unsolicited message is
issued (if C17 is ON) .
If an assignment command is received and the thermostat program format is programmable (i .e . not non-programmable), and the system
mode is set to OFF, this command is ignored .
If the resultant setpoint is outside the allowable range for the setpoint temperature, the command is ignored .
