The Danfoss RTC DDC is used with SCC/SGC series

An A2 return air sensor monitors return air temperature
and provides input to the DDC to determine unit heating or
cooling function.
An A74 room air sensor is used to monitor space tempera-
ture. Do not install the return air sensor if a room air sensor
is used. The room air sensor is wired to the Prodigy® con-
trol by the controls contractor.
The RT1 discharge air sensor monitors discharge or sup-
ply air temperature.

vice or maintenance can cause personal injury, loss
