SPEED CONTROLLER 2-SPEED CONTROL

The hat rack module adjusts the EC fan speed in two stages. The stages are selected via a switching contact input. If a timer switch is connected to the module's switching contact input, the fan speed can be adjusted according to the time of day (day and night mode). Alternatively, the current speed level 1 or 2 can also be selected via a manual switch. The two speed levels can be set using two rotary dials. In stage 1 (day operation), the fan speed can be set from 0 to 100 %. In stage 2 (night reduction), the fan speed can be set from 0 to level 1. Features
