Connection of floor sensor (terminals 6-7)
! Install line at sufficient distance from
mains cables.
Note: If the sensor line is interrupted or in
the case of a sensor failure, you have the
option to temperarily install a fixed resistor
in order to ensure heating operation.
• Line interrupted (high-impendance) = heating operation
• 25,0 kΩ fixed resistor =ˆ
approx. + 10° C
• 10,0 kΩ fixed resistor =ˆ approx. + 25° C
• 6,8 kΩ fixed resistor =ˆ approx. + 35° C
