+This node expects a numeric msg.payload containing the current temperature (number). The msg.topic should be `empty` or set to `setCurrent`. It will calculate the target temperature depending on msg.payload at the current time and output 3 values:
 
 * state (boolean)
-* current temperature
-* target temperature
+* current temperature (number)
+* target temperature (number)
 
 The state (true/false) is used to control an actuator. The current and target temperature outputs can be wired e.g. into an ui_chart node.
