Chapter 1: Introducing Supra Touch
Getting to know Supra Touch
Supra Touch is a powerful yet easy-to-use climate controller for up to four independent zones. It monitors
conditions in each zone and operates equipment such as fans, heaters, inlets, and curtains to provide the
optimal environment you need.
Secondary modifiers
Supra Touch is more than a temperature-based control. You can measure other conditions such as humidity,
ammonia, carbon dioxide, and wind speed. Secondary modifiers allow you to use these measurements to
influence how Supra Touch controls equipment. For example, if the humidity is too high you can have the
control switch on heaters and/or increase ventilation to reduce it.
VentGrid™
In addition to traditional staged control, Supra Touch offers VentGrid merged mode. VentGrid has up to
10 steps that can provide smoother transitions between steps than staged mode can between stages.
Curves
Growth and minimum ventilation curves allow you to automatically change the temperature set point and
minimum ventilation rate over time to adjust to requirements as your animals grow.
Easy to program, manage, and monitor
The touchscreen display allows you to easily configure, program, and check the status of zones and
equipment. From the status screen, you can easily access configuration, settings, and more. Every powerful
feature is never more than a few taps away. This makes the Supra Touch one of the easiest-to-use and user-
friendly controls.
Security and peace of mind
Supra Touch has a screen lock security system. While screen lock is enabled, users can view the status screen
but must enter the PIN before they can access any of the control’s functions.
Supra Touch is compatible with most alarm systems. You can connect the control to an alarm siren or other
external alarm system. Customizable alarm settings allow you to choose which alarm conditions you want to
be notified about.

Chapter 2: Installing the Supra Touch
What you need to know before installing the Supra Touch
1. Read Understanding power surges and surge suppression below.
If you do not install external surge suppression devices, you risk damage to the
electronics inside the Supra Touch, which may cause the Supra Touch to fail.
Because it is not possible to completely protect this product internally from the
effects of power surges and other transients, we highly recommend that you install
external surge suppression devices. For specific recommendations, see your
electrical contractor.
If you do not take these precautions, you acknowledge your willingness to accept
the risk of loss or injury.
2. List all the equipment you want to control on the Installation worksheets (starting on page 80). Install
the equipment and make your electrical connections according to the sheet.
3. Use the installation worksheets to complete the Configuration worksheets (starting on page 82). List the
equipment that is connected to each of the terminals and how you want it configured.
Understanding power surges and surge suppression
Power surges can be caused by external influences (influences outside the barn; for example, lightning or
utility distribution problems) or they can be caused internally (inside the barn; for example, starting and
stopping inductive loads such as motors).
One of the most common causes of power surges is lightning. When lightning strikes the ground, it
produces an enormously powerful electromagnetic field. This field affects nearby power lines, which
transmit a surge to any device connected to it, such as lights, computers, or environmental controls like the
Supra Touch. Lightning does not have to strike a power line to transmit a surge.
Surge suppression devices offer some protection from power surges. Because it is not possible to internally
protect this product completely from the effects of power surges and other transients, Phason highly
recommend that you install external surge suppression devices. For specific recommendations, see your
electrical contractor. If you do not take these precautions, you acknowledge your willingness to accept the
risk of loss or injury.
Reducing electrical noise using filters
Electrical noise is caused by high voltage transients created when inductive loads, such as power contactors,
are switched on or off. The strength of the transients can be over 1000 volts and can vary with the type of
equipment and wiring, as well as several other factors.

Phason 9 / 98 34740001
Visible symptoms of electrical noise include erratic control operation, cycling inlets, communication
problems, and more. However, the effects of electrical noise are not always visible. Over time, electrical
noise can cause electronic circuits, relay contacts, and power contactors to deteriorate.
Installing filters helps extend the life of equipment
Filters help prevent electrical noise problems by absorbing the transient energy. Even if you do not have
visible symptoms of electrical noise, filters help keep controls operating reliably and can extend the life of
the controls and equipment connected to them.
Phason’s snubber filters (model 127-0) are for use with solenoids, timer relays, DC motors, furnaces, and
other equipment connected to the control’s relays. You can also use the filters with loads connected to
power contactors.
Do not use Snubber filters with variable stages.
Some power contactors include snubber filters. For more information, read Using power
contactors to increase the capacity of relays on page 10.
For more information about snubber filters or other Phason accessories, see your dealer
or visit www.phason.ca.

You can connect more than one piece of equipment to a variable stage or relay as long as they are the same type (for
example, two fans) and the total current draw does not exceed the stage’s limit.
The FLA (full load ampere) rating accounts for the increase in motor current draw
when the motor operates at less than full speed. Make sure the motor/equipment
connected to the variable stage does not draw more than 7 FLA.
Using power contactors to increase the capacity of relays
Phason’s Manual Override Box (model MOB-4) has four 240-volt power contactors that allow you to
increase the load handling capability of control relays. Manual Override Box is ideal for secondary
ventilation fans and electric heaters.

Phason 13 / 98 34740001
Mounting the Supra Touch
1. Select a location for the Supra Touch. Make sure you have enough
cable and wire to reach all the equipment that you want to control.
2. Remove the screws from the front cover and then gently lift it off.
3. Mount the enclosure to a wall using the four screws provided with
the control. Insert the screws into the large holes in each corner of
the box and tighten.
Connecting equipment to the Supra
Touch
Follow these instructions when installing the Supra Touch and connecting equipment to it.
Use the electrical knockouts for bringing wires or cables into or out of the Supra Touch
enclosure. Do not make additional holes in the enclosure; this can damage the watertight
seal or control components and void the warranty.
Supra Touch test modes are useful for testing your equipment after installing and
configuring it. For more information, read Testing sensors and equipment on page 67.
If you used the Installation worksheets on page 80 when preparing, refer to them when
installing equipment.
Connecting actuators (inlets with feedback)
In Supra Touch, actuators are considered “inlets with feedback”. Linear actuators are connected to inlets
either directly or with cables and pulleys. Inlets are generally located in the ceiling or walls. Inlet systems are
usually spring loaded to aid in closing the inlet or counter weighted to aid in opening the inlets.
You can connect two actuators to a Supra Touch. Each inlet requires two relays: one for opening and one
for closing. We recommend choosing relays that are side-by-side.
If your actuators do not require feedback, it is considered a curtain, or, “inlet without
feedback”. For more information, read Configuring relays for inlet actuators or curtains on
page 32.

Phason 14 / 98 34740001
Feedback potentiometers
Each actuator you connect must have a feedback potentiometer. The feedback potentiometer, which you
connect to one of the two corresponding feedback terminals, lets the control know how far the actuator’s
arm is extended.
Most linear actuators are available with potentiometer feedback and internal adjustable limit switches. A
10,000 ohm, 10 turn feedback potentiometer is preferred, but the internal feedback potentiometer can range
between 1000 and 20,000 ohms. Potentiometers outside of this range will affect the precision to which the
Supra Touch can control the actuator.
A system operates more precisely when using the largest amount of stroke that is
feasible with the actuator. The stroke is the distance the actuator arm extends or retracts.
If you are unsure of the potentiometer wiring for your actuator, read Determining correct
actuator feedback wiring on page 78.
When routing the actuator feedback wires, do not run them in or along the same conduit
as AC-power lines. Follow the guidelines in the Control fundamentals guide.
If you are measuring AC power with a digital multimeter (DMM), note that if a limit switch
opens the circuit, the DMM measures voltage after the relay switch even if the relay is
open.
The ratings of the actuator must not exceed the ratings of the Supra Touch.
Supra Touch relay ratings: 10 A at 120/230 VAC, general-purpose (resistive)
1/3 HP at 120 VAC, 1/2 HP at 230 VAC
360 W tungsten at 120 VAC
To connect actuators
Connect actuators as shown below. Refer to your actuator’s installation guide for information about its
power supply requirements.
AC-powered actuators
DC-powered actuators

Phason 15 / 98 34740001
Connecting curtain machines
Curtains are usually controlled by equipment called curtain machines, which are sometimes referred to as
winches. Curtains are opened and closed to let in more air or less air, the idea being more air cools the
building.
Each curtain machine you connect requires two relays: one for opening the curtain and one for closing the
curtain.
In Supra Touch, curtains are considered “inlets without feedback”. If yours does require
feedback, it is considered an actuator, or, “inlet with feedback”. For more information,
read Configuring relays for inlet actuators or curtains on page 32.
For connecting air curtains, see Connecting fixed-speed cooling or heating equipment and
on page 16.
The ratings of the equipment must not exceed the ratings of the Supra Touch relays.
Relay ratings: 10 A at 120/230 VAC, general-purpose (resistive)
1/3 HP at 120 VAC, 1/2 HP at 230 VAC

Phason 16 / 98 34740001
Connecting fixed-speed cooling or heating equipment and air curtains
Fixed-speed heating ting or cooling equipment includes electric heaters, furnaces, single-speed fans, and any
other equipment that is either on or off.
The ratings of the equipment must not exceed the ratings of the Supra Touch relays.
Relay ratings: 10 A at 120/230 VAC, general-purpose (resistive)
1/3 HP at 120 VAC, 1/2 HP at 230 VAC
360 W tungsten at 120 VAC
Gas furnaces using hot-surface ignition or glow plug can draw more current than
indicated on their nameplate and require power contactors. For more information, read
your furnace dealer.
To connect equipment to relays
Connect equipment as shown below.

Phason 17 / 98 34740001
Connecting variable heating or cooling equipment
Variable cooling equipment includes equipment such as variable-speed fans. Variable heating equipment
includes equipment such as heat mats and heat lamps.
Only permanent split capacitor motors appropriate for variable speed control, or shaded
pole motors, can be used on the variable stages.
If you are using three-phase power, connect the Supra Touch and the variable cooling
equipment to the same phase. For more information, read Using three-phase power on
page 18.
The ratings of the equipment must not exceed the ratings of the Supra Touch’ variable
stages.

Variable stage fuses: 15 A, 250 VAC ABC-type ceramic
To connect equipment to variable stages
Connect variable heating or cooling equipment as shown below.

Phason 18 / 98 34740001
Using three-phase power
If you are connecting the Supra Touch to a three-phase system, make sure to connect the control power and
the variable cooling equipment to the same phase. The control must be powered from the same phases that
supply the equipment. If the control and the variable stages are wired to different phases, the equipment will
operate erratically.
Connecting an alarm system
You can connect an alarm system to the alarm terminal on the Supra Touch. The alarm system can be a
siren, alarm panel, auto-dialer, or similar equipment. Read your equipment’s’ installation guide for
information about the type of system: normally open or normally closed. Below are the descriptions for the
alarm terminal.
C / CC: common connection
NC / CA: closed on alarm
NO / OA: open on alarm
For the alarm system to sound (or dial out) during an alarm condition, you must enable the alarms. For
more information, read Programming alarms on page 43.
The ratings of the siren or alarm system must not exceed the ratings of the Supra Touch’
alarm relay.
Alarm relay ratings: 0.4 A at 125 VAC; 2 A at 30 VDC, resistive load
0.2 A at 125 VAC; 1 A at 30 VDC, inductive load
Correct three-phase wiring
Incorrect three-phase wiring

Phason 19 / 98 34740001
To connect a normally open alarm system
If you are connecting an alarm system with a normally open connection,
meaning it closes when there is an alarm, connect it as shown in the
normally open diagram.
If you are connecting the alarm system to more than one Supra Touch,
join all the CC connections together and all the OA connections together.
The alarm relays must be in parallel with each other so any of the
controls can trigger the alarm system when an alarm occurs.
To connect a normally closed alarm system
If you are connecting an alarm system with a normally closed
connection, meaning it opens when there is an alarm, connect it as
shown in the normally closed diagram.
If you are connecting the alarm system to more than one Supra Touch,
join the alarm relays in a continuous loop. The alarm relays must be in
series with each other so any of the controls can trigger the alarm system
when an alarm occurs.
Connecting sensors
Supra Touch gives you the ability to monitor more than just zone temperatures. Connecting additional
sensors gives you the ability to use modifiers that allow you to override settings when certain conditions are
met, such as when carbon dioxide levels are too high. For more information, read Programming modifiers
on page 41.

Follow these guidelines when connecting any type of sensor:
Do not run the sensor cable in the same conduit as AC power cables
Do not run the sensor cable beside AC power cables or near electrical equipment.
When crossing other cables or power lines, cross them at a 90-degree angle.
3K Series temperature sensors
You can connect four Phason 3K Series temperatures sensors to
any of the TEMP1 to TEMP4 terminals. These terminals are for
zone control.
If you have sensors connected to more than one terminal and they are
configured for the same zone, the control will average the temperatures
to provide a more-balanced reading for the zone. For more information,
read Configuring sensor inputs on page 28.
You can also connect a Phason 3K Series temperature sensor to the
OUTDOOR TEMP terminal for monitoring outdoor temperatures.
If there are no functioning temperature sensors, Supra Touch controls the equipment as if
the master set point for the zone is the actual temperature.
Replace damaged temperature sensors as soon as possible. If a temperature sensor is
damaged, disable it until you can replace it with a new one.
When routing the temperature probe cables, do not run them in or along the same
conduit as AC-power lines.
You can extend probe cables up to 500 feet. For more information, read the Control
Fundamentals guide that came with your control.
Relative Humidity Sensor
You can connect a Phason Relative Humidity Sensor (model RHS or
RHS-P) to the ANALOG terminal.
1. Position the jumpers on the pins as shown.
2. Connect the wires from the humidity sensor as shown.
