ELEKTRA TDR 4022-PRO
controller
for DIN bus mounting in electric switchboards,
applied in extended and complex heating
systems, two relays, load 8A each,
recommended total power of directly
connected self-regulating heating cables
is 600 W. The controller allows to set two
temperature levels and to adjust hysteresis.
The controller cooperates directly with BMS systems
via ModBus or Televis protocols or in an analog mode
via a relay operating in the alarm mode.
5.2. Controls of gutter, downpipe and roof
heating systems
The most efficient and economical heating system will be controlled with
a device equipped with a temperature and moisture sensor. The system
will be then switched on only when both sensors indicate snowfall,
freezing rain or icing. Depending on the size of the system and number of
zones to be heated, ELEKTRA ETR2 controllers are recommended with one
moisture sensor, or ELEKTRA ETO2 controllers with one or two moisture
sensors and an external temperature sensor.
ELEKTRA ETOR2
controller
for DIN bus mounting, load 3x16A,
factory-equipped with one temperature
and moisture sensor, allows to connect
the second auxiliary moisture sensor
for protection of two heated zones.
