Data sheet Thermostats AFT 06, AFT 26, AFT 17, AFT 27 Description AFT 06 AFT 26 AFT 17 AFT 27 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; For the AFT26 and AFT27 designs - wall mounted, it is delivered separately. There are two sensor designs with different time constants. 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. Combinations: temperature controller, safety temperature monitor, safety temperature limiter, see page 4. Type-tested according to EN 14597 in connection with the following valves: VFG 2, VFG 21, VFGS 2, VFG 33 and VFU 2. Main data (valve & thermostat): • DN 15-125 • PN 16, 25, 40 • Setting ranges: • Temperature: - Circ. water / glycolic water up to 30 %: 2 … 130 °C • Connections: - Flange • Flow and return mounting. −20 … 50 °C / 20 … 90 °C / 40 … 110 °C / 60 … 130 °C / 110 … 180 °C and −20 … 50 °C / 20 … 90 °C / 40 … 110 °C / 60 … 130 °C DEN-SMT/SI VD.GA.G3.02 © Danfoss 05/2015 1
