SAFETY REQUAREMENTS
Read these instructions carefully to make sure CS-503
will work without any problem in all conditions.
Do not install any kind of cascade controller
equipment directly on boiler or boiler
equipment surface to protect device and
cables against high temperatures.
Cables connecting each boiler should be
covered and positioned in a safe way, so no
heat ash or dust will damage them in long term
use.
Prevent
installation
of
electronical
components in boiler rooms with high
humidity.
CS-503 cascade controller shouldn’t be
installed close to any kind of wireless or
electromagnetically operated device. Safe
distance is 50cm or more.
Update boiler control unit to the latest
firmware version to make sure cascade
operation is included in controller’s submenu.
Communicate the exact way of operation with
your installer to be sure cascade controller
operates all boilers in a way you need.
Consider both possible operations with CH
boiler temperature sensor and outside
Weather sensor.
Weather sensor is included in 431N module
packaging which is part of each burner box. To
make weather cascade operation work, also
431N module must be installed into the boiler
connected in 1
st
RS output of cascade
controller.
