WARNING:
Do not apply any voltage to terminals IN0 and IN1 as this will damage the CCS PCB inside
the air curtain.
NOTE:
The Controller must stay plugged-in for the air curtain to keep working. An optional plug-in
EEPROM is available from Biddle so the Remote Control can be un- plugged and the air curtain stay
working. Visit the Biddle website for details.
Overheat safety cut-out indication
For electric heated air curtains the CCS PCB includes a fault indication signal for if the overheat safety
cut-out on the electric heater operates.
Volt free changeover contacts (1A 240VAC 30VDC) can be wired via the 7-way screw terminal (see Fig
10).
Refer to Section Overheat Safety cut out, for how to reset a overheat safety cut-out situation.
Weather compensation control (Summer/Winter)
To save heating energy on warmer days a simple weather compensation (Summer/Winter) heat control
strategy can be used. Fit an outdoor air thermostat with volt-free contacts (supplied by the installer) to
a north facing wall.
Use a 2-core cable to connect the outdoor air thermostat to 2-way terminal IN1 on the CCS PCB (see
Fig 11) and on the CCS PCB, set DIP 4 to OFF as per Table 3.
