3.9.2 Floating Setpoint - changeable analogue input slope NTC

Introduction The CH. AI SLOPE NTC mode can be used to modify the setpoint in function of the NTC sensor which

is connected to a changeable analogue input (and programmed) the user is able to choose to use the

floating setpoint or not. The result of using the CH. AI. SLOPE NTC mode is that the unit will change

setpoint according to the measured temperature. The floating setpoint parameters and functions can

be set in the user/floating setpoint menu.

description

Explanation When the temperature measured with the NTC sensor is 20 °C (reference), then the original setpoint

will be used. When the measured temperature rises, the active setpoint will change downwards. When

the measured temperature drops, the active setpoint will change upwards.

Remark: when you use the floating setpoint, the value of the setpoint on the readout and setpoint menu

can be different. The readout screen will show the calculated value and the setpoint screen the set

table.

A: Active setpoint

B: Setpoint
