Sensors measure and transmit all variations encountered at their location. Measurement is taken based on design features (time constant) and according to specific operating conditions.With wiring run in raceways, the sheath (or pipe) containing the wires must be plugged at the sensor's terminal board so that currents of air cannot affect the sensor's measurements.

  • Page 109 MANUALE USER SUPPORT MULTI-THERMOSTAT MCX06C MCX06C is a multi-thermostat with four 100k NTC inputs. It can control up to 4 temperatures showing them (not more than 2 at the same time) on a couple of displays. It is used to check and adjust oil heater temperatures. it works as follows: as soon as the burner control gives the GO to the digital 1 input (terminals DI1-COM), the adjustment program runs (the relevant LED is ON).

  • Page 116 Alarms & Warning: When the red triangle on the top left lights, one or more alarms are activated. When the red key on the left lights, the output N05-C5 is active and the relay KTRS switches the resistors OFF. Check the reason, correct the failure and, as soon as the temperature is lower than trS, reset it through ALA/rES . In order to show active alarms and warnings, select the relevant menu through ALA/Act.and, using the UP and DOWN buttons, scroll the lines.
