Remote switch contacts IN0, IN1
Terminals IN0 and IN1 on the CCS PCB inside the air curtain can be used to provide different control
strategies using remote volt-free contacts (see Fig 9). This could be to provide remote On/Off from a
timer or BMS Digital/Output contact, to work with a door switch or for simple weather compensation
control to disable heating when outdoor air temperatures become warmer. Table 3 describes the
different functions:
