Chapter 1: Introducing Plus Touch
Getting to know Plus Touch
Plus Touch brings a wealth of features that make it a powerful, versatile, and easy to use control.
Plus Touch has two variable AC stages and six relays to automatically control temperatures by
operating ventilation, heating, and cooling equipment according to your programmed settings.
Plus Touch is more than a temperature-based control; it can use other environmental conditions to
influence how it controls equipment. For example, if the humidity is too high in the zone, Plus
Touch can switch heaters on or increase ventilation to reduce it.
In addition to traditional staged control, Plus Touch offers VentGrid™ merged mode. Merged mode
has up to four steps, with the benefit that merged mode can provide smoother transitions between
steps than staged mode can between stages.
The growth and ventilation curves are powerful features that allow you to automatically change the
temperature set point and minimum ventilation rate over time to adjust to requirements as your
animals grow.
Plus Touch is ideal for swine, poultry, dairy, greenhouse, and light-industrial buildings, and is
compatible with most ventilation strategies.
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 Plus Touch one of the easiest-
to-use and user-friendly controls.
Security and peace of mind
Plus Touch has a screen lock security system. While screen lock is enabled, users must enter the PIN
before they can access any of the control’s functions, except the main status screen.
Plus 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 Plus Touch
What you need to know before installing the Plus 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 Plus Touch, which may cause the Plus 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 using this Plus Touch on the Installation worksheet
on page 77. Install the equipment and make your electrical connections according to the sheet.
3. Use the Configuration worksheets starting on page 79. List which relays and variable stages you
want to use for each piece of equipment, and how you want the equipment configured.
You can connect more than one piece of equipment to a single relay or stage as long as the total
current draw does not exceed the relay or stage’s limit. For more information, see the electrical
ratings on page 11.
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 Plus Touch. Lightning does not have to actually 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.

Chapter 2: Installing the Plus Touch

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.
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 11.
For more information about snubber filters or other Phason accessories, see
your dealer or visit www.phason.ca.

Mounting the Plus Touch
1. Select a location for the Plus Touch. Make sure you have
enough cable and wire to reach all the equipment (fans,
heaters, misters, curtains, etc.) 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 Plus Touch
Follow these instructions when installing the Plus Touch and connecting equipment to it.
Use the electrical knockouts for bringing wires or cables into or out of the Plus
Touch enclosure. Do not make additional holes in the enclosure; this can damage
the watertight seal or control components and void the warranty.
Plus Touch test modes are useful for testing your equipment after installing and
configuring it. For more information, read Testing sensors and equipment on
page 63.
Refer to Appendix C: Installation worksheet on page 77 and Appendix D:
Configuration worksheets on page 79 when installing equipment.
Connecting actuators
You can connect up to two actuators to a Plus Touch. Actuators are used for equipment that is not
OFF or ON, but instead varies by a percentage. For example, inlets can be open various distances
from 0 percent to 100 percent.
Linear actuators are usually connected directly to inlets, or using 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.
Each actuator you connect requires two relays: one for opening, and one for closing. Actuators must
be connected in the following combinations.
Actuator 1: Relay 1 –open Actuator 2: Relay 3 –open
Relay 2 –close Relay 4 –close

Connecting equipment to the Plus Touch
15
Actuators can be connected to relay pairs 1 and 2 or 3 and 4 only. Actuators
cannot be connected to any other combination of relays. For example, you cannot
connect an actuator to relays 1 and 3.
In Plus Touch, actuators are considered “inlets with feedback”. If yours does 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 33.
Feedback potentiometers
Each actuator you connect must have a feedback potentiometer. The feedback potentiometer, which
you connect to one of the Plus Touch’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 Plus 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 75.
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 Plus Touch.
Plus 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 to the Plus Touch as shown below. Refer to your actuator’s installation guide for
information about its power supply requirements.
Connecting curtain machines
Curtains are usually controlled by equipment called curtain machines (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.
You can connect up to two curtain machines to the Plus Touch. Each curtain machine you connect
requires two relays: one for opening the curtain, and one for closing the curtain. Curtains must be
connected in the following combinations.
Curtain 1: Relay 1 –open Curtain 2: Relay 3 –open
Relay 2 –close Relay 4 –close
In Plus 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 33.
The ratings of the equipment must not exceed the ratings of the Plus Touch relays.

Using three-phase power
If you are connecting the Plus Touch to a three-phase system, make sure to connect the control
power and the variable cooling equipment to the same phase.
The Plus Touch must be powered from the same phases that supply the equipment. If the Plus
Touch power 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 Plus Touch’alarm terminal. An alarm system can be a siren,
alarm panel, or auto-dialer. Read your system’s installation guide for installation instructions and
information about the type of system: normally open or normally closed. Below are the descriptions
for the alarm terminal.
COMM: common connection
N/O: normally open; closes during alarm conditions
N/C: normally closed; opens during alarm conditions
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 45.
The ratings of the siren or alarm system must not exceed the ratings of the Plus
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
To connect a normally open alarm system
If you are connecting the alarm system to a network of Plus
Touch controls and your system uses a normally open connection
(closes on alarm), connect the system as shown in the normally
open diagram.
Join all the COMM connections together and all the N/O
connections together. The Plus Touch alarm relays must be in
parallel with each other so any Plus Touch can trigger the alarm
system when an alarm condition occurs.
To connect a normally closed alarm system
If you are connecting the alarm system to a network of Plus
Touch controls and your system uses a normally closed connection
(opens on alarm), connect the system as shown in the normally
closed diagram.
Join the alarm relays in a continuous loop. The Plus Touch alarm
relays must be in series with each other so any Plus Touch can
trigger the alarm system when an alarm condition occurs.
