How to use the LUMii Contactor:-

The LUMii unit can be hung from a wall by the attached fixing bracket. This is highly recommended to keep all elecricals safe and out way of water and feeding hydroponic systems. With the unit unplugged, programme the timer on the front by moving the tabs on the face of the Grasslin timer to the outer position for those times that you would like power to be on, and set the others to the inner position for the times you would like the power to be off. Each segment corresponds to 15-minutes. A pencil or other small item can be handy for pushing the segments in or out with.

Move the timer-face clockwise until the current time lines up with the arrow. The hands on the clock in the centre will then also correspond to the correct time. There is an override switch to the lower-right side of the clock. This can be set to "0" for "Always Off" or it can be set to "1" for "Always On". The centre position of the switch is for "Timed On" and this will be the normal setting for the unit when it is in use to switch your lights on and off according to your set programme.

Plug your ballasts, fans or other electrical items to be switched, into the sockets on the LUMii Contactor Switching Unit. Make sure that the switches on the outlets are in the "On" position. Insert the rubberised mains plugs into separate mains outlets. Ensure the timer override switch is in the middle position. The contactor will now switch your lighting system on according to the programme set on the timer. Do not overload the contactor by using it to switch more than 4KW. Also, do not plug more than 1 grow light into each socket.

Although the LUMii Contactor with Grasslin Timer can handle the switching of up to 4000 Watts, it is worth bearing in mind that traditional (non-digital) HID lighting ballasts draw a considerable surge at switch-on which is well more than their normal running wattage. Several lighting ballasts being switched on simultaneously may cause the circuit breaker in your consumer unit to trip if that circuit is being run too close to its limit.
