SC-20 is designed to control the heating and cooling system. A wide range of configuration
makes the controller perfect for use in typical arrangements, such as boiler or circulating pump
Control and complex, for example: solar collector or fireplace with water jacket control.
Adjustment is based on the measurement from one or two temperature sensors:
–when measuring from one sensor (F10=0) controller mainstains the set temperature switching on the
main output in ''heating'' or ''cooling'' mode with deviation (regulated hysteresis)
– when measuring from two sensors the user can select the operating mode of the controller:
–the output is activated based on the difference (F10=1) or average (F10=2) from two
temperature sensors.
In differential mode, the controller activates, e.g. Collector circulating pump after reaching an essential
difference between boiler's and collector's sensor. And in averaging mode, the controller operates as
an usual temperature controller except that the measured value is calculated from the arithmetic
average of readings from two temperature sensors, for example at the two ends of the pipeline or the
boiler.
Be aware of the conditions where the controller operates. Install in a place, where there is not
too high temperature and humidity and no condensation. Should be ventilated
in order to remove the heat.
ATTENTION!
It is not allowed to work with electric cables when the device is energized.
You should avoid crossing wires using short connections. We recommend securing the source
of controller power supply and temperature sensor input against electrical interference
Controller meets the requirements for immunity to electromagnetic interference in an
industrial environment according to the following standards:
Electromagnetic compatibility (EMC):
–EN-61000 part 6-4 – requirements for emissivity in an industrial environment
–EN-61000 part 6-2 – requirements for immunity in an industrial environment
It also meets the safety requirements according to standard:
–EN-61000 part 1 – safety requirements for eletrical devices
Controller meets the requirements of EU directives No. 72/23/EEC; 93/68/EEC; 89/336EEC.
