CAUTION
• If the motor is On/Off type, HI/MED/LOW wire have to connect as common.
For example, If you just connect HI wire to the motor(On/Off), motor is not operating
according to our control logic.
• High, Middle, Low wire from AHU Comm. Kit should not be connected directly to the
motor. Always use it as a motor for driving the relay contacts. Otherwise there is a risk of
damage to product or a fire.
