kitControl-Tstat
This component provides basic thermostatic (On/Off) control with a StatusBoolean Out property and StatusNumeric inputs for controlled variable (Cv), setpoint (Sp), and differential (Diff). An Action property configures the operation directly or in reverse. A Null On Inactive property is also available. Default action is Direct (cooling).
Tstat is available in the HVAC folder of the kitControl palette.

| Sp | number (defaults to null) and null definition | Defines the input thermostat Setpoint (Sp). When null is checked, the corresponding value defines the default when a calculation returns null. |
| Dif | number (defaults to null) and null definition | Defines an input differential (Dif). When null is checked, the value displayed defaults to the incoming value from the device.If you remove the check mark you can configure the In value. |
