WIRING OF DUCT SENSOR TEMPERATURE (CDT)
When using ventilation systems with electric duct heater
connection and using the CONTROL BLOCK PRANA-340S H
control unit, a complete duct temperature sensor should be
in the complect.
The complete sensor is housed in a dust and moisture-
proof protective enclosure with a 2 metre-long conductor. If
necessary, the wire can be extended to the required length
using 2x0.75 conductors.
Channel temperature sensor - monitors the set temperature
and regulates the power of heating elements by switching
the heating element on and off alternately. The sensor is
installed in the tidal air duct at a distance of 0.5 m after the
duct heater.
