ZANO GRID RANGE
USING THE MINIMUM LEVEL PRE-SET
The Zano grid range can control a range of loads depending on
various factors which are laid out in the table below. See overleaf
for maximum total loads on cover plate recommendations.
The minimum level pre-set is located on the side of the ZGRID500
and the ZGRID700. This is used to set the minimum level of light
to a stable level to get the best from your dimmable lamps. This
can be adjusted with a small screwdriver when the dimmers
potentiometer is turned to the lowest point. Ensure mains are
isolated and adjust in small intervals to find stable light point at
minimum level ensuring it’s safe.
( Be sure to turn power off before adjusting!)
It is essential before making any connections to check the load
that requires dimming and to cross check the table to ensure the
load meets the specification of the dimmer switch. Connection
loads outside of the specification will invalidate the guarantee.

1. Most dimmers have a micro processor which is not suitable with linear
loads as these can be too efficient and chip doesn’t recognise load.
2. Dimmers without minimum level pre-sets can dim load too low which
causes gasses in lamps to cool down to an unstable level or voltage is
reduced beyond lamps minimum voltage level for operating.
If you are dimming LED loads we now recommend our ZGRIDLED
dimmer, it differs from our standard grid dimmers with brand new
technology which ensures silent, flicker free LED dimming every time.

Dimming Information
Electronic transformers
Mains tungsten halogen
To meet the load specification only lamps with an integral fuse
should be used. We recommend lamps from the following
manufacturers: Philips, Osram, GE, Sylvania, Megaman and Aurora.
Wire wound & torroidal transformers
Wire wound transformers are intrinsically dimmable and
provide a very reliable load for any dimming product. Take
note to de-rate as per loading chart.
The ZGRID500 uses leading edge technology, which unlike
transformers which are trailing edge, does not cause
flickering and buzzing. We recommend transformers from
manufacturers Collingwood and Mode. It is generally
recommended that transformers are loaded to a minimum
of 70% of their rating to avoid lamp flicker or poor dimmer
operation. Zano Controls can advise or test if a specific
transformer is required. Call our friendly technical support
team on 0845 519 5858.
We provide this information as guidance only and accept no
