A temperature/time controller is required for all Electric UFH installations and is especially
important under wooden fl ooring.
Select from 6 different operating modes
External sensor: An additional wireless temperature sensor can be taught in.
Internal sensor: Temperature is regulated by an internal temperature sensor.
Int. sensor+fl oor: Temperature is regulated by an internal temperature sensor and a maximum fl oor
switch-off temperature can also be set.
Floor sensor: Temperature is regulated by an external fl oor temperature sensor.
PWM controller+fl oor: Temperature is regulated by an external fl oor temperature sensor using PWM.
PWM actuator: Temperature is regulated using PWM 5 to 60 min and a maximum fl oor
switch-off temperature can also be set.
