Timer For Use With Brew Belts, Heating Pads / Trays
This solution works. Simply push down the black segments evenly so that you get a constant temperature. Pushing them all down will turn the heating device on 100%, while pushing every second one down will turn the heating device on 50% etc. (see the timer instructions below).
Things that don't work:
The instructions on most brew belts that ask you to move the belt up and down DO NOT work. Moving the belt up to reduce heating effect is utter madness: it simply creates a thermoclyne (a hot layer on top) that will destroy your brew. Heating pads don't work either (without a timer) since there is no way to control the temperature.
1). Insert the timer into the required socket outlet, and then plug the brew belt to be controlled into this timer.
2). Push down the black segments on the timer face corresponding to the desired operating time. (One segment = 15 minutes)
3). Turn the disk clockwise, following the direction of the arrows, until the grey marker is pointing at the current time.
4). To activate the timer function ensure that the switch on the side is down and so indicating the timer symbol.
5). For manual override, to disable the timer function, move switch to the up position and thus covering the timer symbol.
6). The LED indicator will illuminate to show power to the timer socket outlet, when it is in operation. Maximum load=13A (3120W)
