AFT 06/17 Thermostat
Brand: Danfoss
The thermostats operate according to the liquid expansion principle. For the AFT 06, AFT 17 designs, the setpoint adjuster is directly fitted to the actuator.
There are two sensor designs with different time constants:
- AFT06 smooth sensor ~120 sec
- AFT17 spiral sensor ~20 sec
Temperature control of domestic hot water systems with storage tanks and restriction of the return flow temperature in district heating transfer station are the main fields of application.
