TEMPERATURE PROBE CONNECTION (RTD)
On the Caddy Alterna, a RTD has to be installed on the side of the appliance using the support provided with the
unit. In order to secure the RTD support, remove the two screws already secured to the furnace on the side where
you have chosen to install the pellet central processing unit (Pellet CPU). Then, secure the RTD support using the
two screws you previously removed. Using a drill and a 9/32'' bit, drill a hole in the plenum so that the RTD rod can
pass into it. Then, secure the RTD in place on the plenum using the two self-tapping screws provided with the
owner's manual. The RTD has to be connected to the pellet central processing unit (Pellet CPU). The RTD is a
sensor (probe type) that reads the temperature inside the hot air plenum. Refer to electric diagram for connection
details.
