Digital temperature controller FTAF55D

programmablewireless

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. ■ Bidirectional controller combined with GFVS 4.0. ■ 60 programmable time settings e.g. day/night operation. ■ Internal relay with 16 A switching capacity and zero transition switching. ■ Connection for optional NTC sensors (NTC 8.2/10/12/15/18 kΩ). Wireless temperature controller Air+Floor with display pure white glossy for single mounting 80 x 80 x 14 mm or mounting into the E-design55 switching system. Installation depth 33 mm. With adjustable day and night reference temperatures. Dis play illuminated. Dis play illuminated. Preset ready to operate. Wired temperature sensor for monitoring of fl oor temperature can be connected. 1 NO contact not potentialfree 16 A/250 V AC. Power supply 230 V. Only 0.4 watt standby loss. Smart Home sensor.
