ATQ ACOUSTIC SINGLE PHASE FAN WIRING DETAILS
STOCK REFERENCE NUMBERS:
ATQ 100-12C, ATQ 125-12C, ATQ 150-12C, ATQ 160-12C, ATQ 200-12C
ATQ 250-12C, ATQ 315-12LC, ATQ 315-14HC, ATQ 400-14C.
NOTE: The ITC and ITC-DS controller operate by detecting the current flowing to the fan. If it is necessary to switch
the fan On/Off for any reason; e.g. fan Off at night, this switch operation must be done via the ITC and ITC-DS
controller by making or breaking a contact connected across S1-SG. Otherwise a fan failure will be registered.
