3. Introduction
The Evolution Variable Output models with Override Pot are Hired-Hand's latest addition to the electronic
controller product line. These additional models have the same operational features as the previous models
except the latest models contain the Intensity Control Pot. This Intensity Control Pot allows additional
functionality over the previous versions, including the ability to override the main control system or the ability to
use these units in conjunction with more primitive systems such as 24 hour time clocks for lights or thermostats
for fans. The Evolution Variable Output w/Override Pot is available in two versions: The 4KW/4HP model and the
8KW/8HP model.
The Evolution Variable Output models can be used in conjunction with Evolution 3000/3001 Control Systems,
Farm Hand Control Systems (Stage Master, etc.), alternative manufacturers, 24 hour Time Clocks as a standalone unit, or to any dry contact control output for variable operation of lights or fans.

6. Initial Setup of Variable Output Control Board (PCB 174 rev C or later)
The following sub-sections describe the usage and settings of each connection, jumper, and switch included on the EV-VAR PCB
#174 revision C or later. The board layout with wiring/setting location references are shown in Section 6.1. The latest PCB174
revision C or later include the following product enhancements:
•
Sunset light control functionality is now provided along with the Sunrise feature which was available on the previous
version EV Variable Output controls. The Sunrise and Sunset features can now be used with less sophisticated systems.
•
The Evolution Variable Output controller is now capable of accepting a 0-10 Vdc input signal from alternative control
systems and use that voltage to dim the lights or vary the fans. This function was previously achieved only with HiredHand Environmental Control Systems.
The Evolution Variable Output models can be used in conjunction with several different control devices such as the Evolution
3000/3001 Control Systems, Farm Hand Control Systems (Stage Master, etc.), alternative manufacturers, 24 hour Time Clocks as a
stand-alone unit, or to any dry contact control output for variable operation of lights or fans. Use the PCB 174 Board Layout and
Setting Locations along with the table listed in Section 6.1 as a quick reference to help direct the specific application to the
appropriate switch settings and wiring diagrams on the following pages.

120 VAC is present when power is applied. DISCONNECT POWER prior to setup or maintenance.
Power Source Selector Switch
The Power Source selector switch sets the option for either Local “120 Vac AC” or Remote “DC 10-15Vdc” powering of the
Variable Output control circuitry. Select “120 Vac AC” for control circuit local powering from the 120 VAC “AC Supply” J4
connection. Select “DC 10-15Vdc” for control circuit remote powering from a nearby Evolution or alternative manufacturer’s
controller supplying the required 10-15 Vdc supply voltage to the J1 connection.
NOTE: Even if Remote “DC 10-15Vdc” Power Source is selected, the 120 VAC “AC Supply” must also be connected for
monitoring the AC frequency.
6.4
Input Selector Switch
The Input Selector switch sets the option for either “Hz-Evolution” (Hired-Hand manufacturer) or “0-10Vdc Input” (alternative
manufacturers) control of the Variable Output light or fan operations. Select “Hz-Evolution” at the “Input Selector” switch for
connections to a Hired-Hand variable module. Select “0-10Vdc Input” for connections to an alternative manufacturer’s control.
NOTE: If “0-10Vdc Input” is selected, ensure the “Sig” connection to J1 is a 0-10Vdc variable input and “12V” is a constant 1015Vdc input from the alternative manufacturer’s equipment.
6.5
Time Clock Connections (Time Signal or Dry Contact Switch)
This connection must be used when an Electronic Controller (Evolution 3000/3001 or Stage Master) is NOT connected.
The switch can be any normally open dry contact, such as a thermostat or a relay output from another control system.
DANGER:
6.6
120 VAC is present when power is applied. DISCONNECT POWER prior to setup or maintenance.
Evolution Connections
The Evolution connections must be wired to the electronic controller (Evolution 3000/3001 or Stage Master) unless an electronic
controller is not used. Observe polarity connections (+ to +; - to -) when an electronic controller is used.
This connection is not used if a 24 hour Time Signal or Dry Contact Switch is connected to the Time Clock connections.
See wiring diagrams for more specific information.
6.7
Variable Out Connections
The Variable Out connection is FACTORY WIRED to EV-VAR PCB #172. (EV-VAR w/Override Pot models only.)
6.8
Status LED
The Status LED should default to a Green color indicating that the power supply is OK. There is also a “Heartbeat” indicator which
will cause the Status LED to turn to an orange or amber color. This is an indication of the processor functionality and the current
mode of operation. The following information details the modes of operation and how they are represented by the flashing orange
color.
•
LED off = check to insure power is present.
•
LED green, no flashing orange = processor error (replace PCB174 board).
•
LED green with quick orange flash = Control in Manual mode; Intensity controlled by override pot.

6.9
LED green with steady orange flash (1/2 second on/1/2 second off) = Control in 0-10 Vdc mode; Intensity controlled by 0-10 Vdc
external signal.
LED green with slow orange flash (1 second on/1 second off) = Control in EV Pulse Mode; Intensity controlled by Evolution
3000/3001 external signal.
Sunrise/Sunset Pot (Light Control Only)
The Sunrise/Sunset Pot is for lights only and will function only in a stand-alone application with either a normally open timer, dry
contact switch, or a 0-10Vdc input signal connected.
The Sunrise/Sunset Pot is used to allow the lights to gradually come ON when a 24 hour timer or dry contact switch is closed and
gradually turn OFF when a 24 hour timer or dry contact switch is opened. Refer to Section 6.13 for a wiring diagram.
The Sunrise/Sunset Pot can also be used with a 0-10 Vdc input signal from an alternative manufacturer’s control. The maximum
light intensity is determined by the specific 0-10 Vdc input voltage. The Sunrise/Sunset Pot is used to allow the lights to gradually
come ON until reaching the specific maximum light intensity determined by the input voltage and gradually turn OFF when the
input voltage is removed. Refer to Section 6.14 for a wiring diagram.
NOTE: The timer or dry contact switch for a stand-alone application is not included with the Variable Output unit.
The Sunrise/Sunset Pot allows settings from 0 to 30 minutes. For example, if 0 is selected, the lights will turn ON immediately
when the timer/contact switch is closed and will turn OFF immediately when the timer/contact switch is opened. If any other
interval is selected, the lights will take the selected amount of minutes to go from low intensity to full light intensity after the
contact is closed and from full intensity to low light intensity after the contact is opened.
6.10 Variable Curves Jumpers
The Variable Curve jumpers are used for selecting the light setting or fan motor curves. The jumper must be placed in the
appropriate position or removed based on the equipment being varied.
IMPORTANT:
Software version V0.07 and later includes new functionality which allows the EV-VAR to function with CFL and CCL bulbs.
Dimmable CFL and CCL bulbs do not dim in the same manner as incandescent bulbs and therefore require testing to choose the
best specific intensity curve that is programmed into the EV-VAR controller.
It is important that both the “Light” curve (jumper installed in the “Light” position) and also the “Jumper Removed” curve (selected
by removing the jumper altogether) be tried and tested to select the one that works best with the customer chosen CFL or CCL
bulbs. When determining which curve to use, vary the intensity of the bulb from 0 – 100% and make sure that there is not a point at
which the bulbs strobe or flicker. If the bulbs strobe or flicker at any point in the curve, it may shorten the life of the CFL or CCL
bulb. Also give special attention and observe the point at which the lights are at full intensity. For example, if the lights seem to be
at full intensity at dimmer setting “6” on the “Light” curve, remove the jumper altogether to see if this gives finer control
throughout the variable range.
The “Jumper Removed” curve is optimized for CFL bulbs such as the ones that Retrolite distributes. It gives the user finer intensity
control throughout the entire range from 0 – 100%.
•
Ensure that software version V0.07 or later is installed before use of CFL or CCL bulbs.
•
If controlling dimmable CFL or CCL bulbs, the jumper selection should be tested for the best results.
Failure to follow these instructions may result in premature bulb failure.
See Curve and Condition Table below for each jumper setting and description.

Condition
For use with incandescent light bulbs; Sometimes also used with CFL and CCL bulbs. Refer to
instructions above.
For this curve, the jumper is not installed in any of the 4 positions. This curve is sometimes used
with CFL and CCL bulbs. Refer to instructions above.
This curve is optimized for use with Hired-Hand’s line of Funnel Flow Fans that are 24” or less.
Also, the line voltage must be Single Phase.
This curve lends itself better to operation of 36” fans. The power distributed at each percentage
is somewhat greater than that of curve FAN0. Therefore, the speed will be a little greater than
that of curve FAN0.
This curve is optimized for use with the Emerson 1/3 hp motors which is used with 24” and
smaller fans.

6.14 EV-VAR To Alternative Manufacturer’s Controller Wiring Connections
The EV-VAR has the capability to be controlled through a 1-10 Vdc output on any control system. If used in this manner, the
“Input Selector” switch must be set to “0-10”.
The EV-VAR can be powered from the control systems DC Supply as long as it is between 10-15 Vdc. If this EV-VAR powering
method is desired, the “Power Source” switch must be set to “DC”.
NOTE: A connection must still be made to a 120 VAC source on the “AC Supply” terminal. This allows the EV-VAR to monitor
the AC frequency to adequately vary the equipment.

6.15 Separating Circuits to Operate Different Equipment
In some cases, you may want to operate a combination of lights and fans. This may be accomplished but only one can be operated
using the manual override pot. The following is an example of how one would wire two circuits for lights and then two circuits for
fans while integrated into the Evolution 3000.
NOTE: In this example, Manual Override using the Intensity Control Pot is only associated with the light circuit.
