Quick Start Guide
Congratulations on purchasing the miniZ Daylight
Harvesting Controller. The miniZ is designed to be
easy to install and configure with a few simple steps.
Simplest Install Steps:
1. Physically install unit and any peripherals
2. Terminate power & control wiring
3. Enable AutoCal & Auto Burn-In
4. Power up system
5. Installation & configuration complete!
Supplement this guide with the full installation manual
provided for more advanced applications.

Control Input: US Models 120VAC& 277VAC terminals, Canadian Models 120VAC & 347VAC terminals

Step 2:
Refer to the Quick Connection Guides found on pages 11-15 of this
guide to connect the line voltage and low voltage circuits. Select the
diagram based on the model you have purchased.
Note: The dimming models have the 0-10V control output wires leaving the
miniZ controller through the same nipple as the supply and load circuit wires.
They are color coded to different zones as indicated in the manual.
For two zone applications:
•Zone 1 should be connected to the luminaires closest to the daylit area such
as the windows or skylights. This is generally accepted to be approximately
12’ to 15’ from the daylight source.
•Zone 2 should be connected to the luminaires in the next area beyond 15’ to
approximately 25’ from the daylight source.
For three zone applications:
•Zone 1 should be connected to the luminaires closest to the daylight area
such as the windows or skylights. This is generally accepted to be
approximately 8’ to 10’ from the daylight source.
•Zone 2 should be connected to the luminaires in the next area beyond 10’ to
approximately 15’ from the daylight source.
•Zone 3 should be connected to the luminaires beyond the 15’ area.

Step 3:
Connect the photocell, occupancy sensor (if used), and the wall station
control per the Quick Connect Guides.
Note: The twozone MZD20 can have two separate wall station controls (see
manual) to operate each zone independently in the manual mode only. If only
one wall station control is used, jumper the two switch input terminals to
control both zones.
Step 4:
Turn the power on to the circuit. The luminaires will come on.

Step 5:
In a closed loop configuration, move the Auto-Cal switch to the ON
position as shown in the manual to activate.
Note: This feature operates the luminaires at full output for a period of 24 hours.
During this time, the miniZ will record the lowest foot-candle reading from the photocell
and record that value as the target illumination. The target illumination is the level that
the miniZ will maintain with the load control output as daylight is available to the
space. The lights will automatically raise or lower (dimmed models) based on how
much daylight is contributing to the overall foot-candle value present to the photocell.
Step 7:
Adjust the proportional dimming output (dimmed models only). The miniZ
has proportional dimming using only one photocell input. Tooptimize the
light level balance in the space, adjustment to the daylight harvesting
threshold trim pots may be necessary.
For a 2 zone application:
•The zone closest to the daylight source (zone 1) should be turned to 10 or full
clockwise. The next zone (zone 2) should be adjusted to 4 on the dial. This will
balance the dimming so that the light level across the space is more uniform.
For a 3 zone application:
•The trim pots should be zone 1 = 10, zone 2 = 7 and zone 3 = 3.
Step 6:
If the fluorescent lamps are new, move the Burn-In switch to the ON
position as shown in the manual to activate the 100 hour Burn-In feature.
This will keep the lamps from dimming until 100 hours of operating time.
After that they will operate in the dimmed mode.
Note: Both the Auto-Cal and the Burn-In can occur at the same time.
