  • Page 10 FCP manual To ensure compliance with the safety standards, the electrical system must be fitted with a suitable switch or disconnector (compliant with standards IEC 60947-1 and IEC 60947-3), located near the appliance. If the appliance is used in a manner that is not specified by the manufacturer, the protection featured for the appliance may be compromised and the appliance may be seriously damaged.

    Parameter copying key Programming key PSOPZKEY00/A0 The programming keys PSOPZKEY00 (Figure 5.1.a) and PSOPZKEYA0 (Figure 5.1.b) are used to copy the complete set of parameters relating to the CAREL FCP controller parameters. The keys must be connected to the PROG KEY connector (4 pin AMP) fitted on the controllers, and work even without switching the controller on (see the summary diagram in Figure 5.1.c.)

  • Page 17: Outside Temperature Compensation (Feedforward Function)

    FCP manual Outside temperature compensation (feedforward function) The operation of the controller can be modified according to the temperature measured by probe B3, proportionally increasing the minimum output value set. This function is especially useful when probes B1 and B2 measure temperature values because, as temperature probes are intrinsically slower to respond than pressure probes, it brings forward the effects of any changes in the outside temperature, increasing the output as the outside temperature increases.
