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.
