SC++, SC--
Increment or decrement the controlling thermostat cool setpoint COS: N/A
Permissions: Write only
Assignment
Command
Syntax: SN[#] SC++=[value]<CR>
Syntax: SN[#] SC--=[value]<CR>
Description: Increments or decrements the controlling thermostat cool setpoint to [value] based on the ++/--.
Examples: SN1 SC++=1<CR>
SN1 SC--=5<CR>
Response Syntax: SN[#] SC++=[value][scale]<CR>
Syntax: SN[#] SC--=[value][scale]<CR>
Example: SN1 SC++=1F<CR>
Node address 1 responds with incrementing the cool setpoint by 1°F.
Parameters Range
value: controlling cool setpoint change value
scale: temperature scale [F, C]
F: Fahrenheit
C: Celsius
The thermostat controlling cool setpoint corresponds to the active cool setpoint to which the thermostat is controlling the cooling equipment.
This command is ignored if the controller type is set to humidistat.
When the thermostat system mode is set to AUTO, the heat and cool setpoints are interdependent and must abide by the deadband. If an
assignment command is received with a cool setpoint decrement value that causes a deadband violation, the heat setpoint is automatically
decreased to fulfill the deadband requirement. If the deadband requirement cannot be fulfilled by decreasing the heat 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 Heat, Emergency Heat or OFF, this command is ignored.
If the resultant setpoint is outside the allowable range for the setpoint temperature, the command is ignored.
