▪
Prior to installing the changeover sensor, thermal conductive paste must be applied
to the location on the pipe where the sensor is placed.
▪
Installation Instructions are included with the controller.
WARNING:
•
Sensor inputs 7, 8, and 9 carry live voltage potential. If the sensor's
cables must be extended, the cables used must be suited for live
voltage.
•
The cables used must meet the insulation requirements for live
voltage.
If the room temperature displayed by the controller is inconsistent with the room
temperature being measured, the temperature sensor of the RDF30U can be
recalibrated. To recalibrate, change Parameter P09.
