DESCRIPTION
The DTC-24 is designed to detect snow or ice and automati-
cally activate a roof de-icing or snow melting cable control
panel.
DTC-24 CONTROl
The DTC-24 control consists of a NEMA 4X enclosure with
a 2 AMP N.O. (Normally Open) relay output contact and a
temperature/moisture sensor. The DTC-24 receives power
from an external class 2 transformer.
A low voltage 6-conductor #22 AWG cable connects the
DTC-24 control to the sensor. All cable leads are color coded
for ease of field wiring.
The DTC-24R comes with a VHB pad for attaching the sen-
sor to the inside of a gutter.
