This 3-position rotary switch for water heat exchangers from AUTOTERM is intended for manual operation of the fan in compatible water heat exchangers. The switch provides direct selection between the positions Off, Low, and High.
The three switch positions include two active fan speeds as well as an Off position. The switch thus provides stepped selection of low or high fan speed and does not function as a thermostat or stepless speed controller.
The rotary switch is designed for compatible water heat exchanger systems with 12 V or 24 V system voltage. It can be used with the AUTOTERM TENERE PERFORMA 3D60 models FR014 and FR039 as well as the TENERE II models FR049 and FR050. It is also an accessory for the water heat exchangers with item no. 50.266.01 and 50.266.02, which are supplied without an integrated switch.
The switch is designed with a black rotary knob and is constructed for panel mounting via a threaded bushing. The operation concerns the heat exchanger's fan and is not a control panel for the Flow liquid heater itself.
