PLUS user manual Getting started
Getting started
Thank-you for purchasing a Phason PLUS control. This manual will help you get the most out of your
PLUS control. Read the manual before installing and configuring your PLUS control.
See Installing the PLUS control on page 15 for installation and wiring instructions. The equipment
connected to the PLUS control must not draw more current than what the control stages are rated.
Equipment that is rated higher than the control ratings will damage the control and void the warranty.
Fill out the Variable speed settings, Relay stage settings, and Inlet actuator settings worksheets.
Use these set-up sheets when making changes to the control’s set points.
If you plan to use the growth curve, fill out the Growth curve setup sheet, and then program the
growth curve settings before adjusting the individual stages.

The Status bar
The Status Bar shows the present status of all stages of the PLUS Control.
NOTE
•
The Alarm indicator lights up when an alarm condition exists.
•
The variable speed indicators, VS-1 and VS-2, light up when power is being supplied to variable
speed fans 1 and 2. You may notice one of these indicator lights glowing fainter than the other, the
fan represented by the fainter light, is running at less than full speed.
The PEC+ layout is shown. The SEC-HD+ has only three relay stages and one actuator
stage.
• The stage indicators, ST-1 to ST-6 (ST-1 to ST-3 for the SEC-HD+), indicate which relays are ON
or OFF.
• The TEMP indicator lights up when the digital display is showing a temperature.
• The TIME indicator lights up when the display is showing a time setting. Two digits to the right of
the decimal will be shown when the value is less than 10.0 minutes and only one when the value is
10.0 minutes or greater.
• The SPEED indicator lights up when the display is showing a speed value (0 to 100%).
• The POS indicator lights up when the display is showing a position value (0 to 100%).
• Pressing Max/Min displays the maximum ambient temperature in the room or zone over the
previous 24 hours, press it again to display the minimum ambient temperature over the previous 24
hours.
• The display “blinks” in this mode. This lets you know the displayed temperature is not the current

Duty cycle
You can designate a relay stage as a duty cycle relay stage (after designating it as either heat or cool)
by using the O/C Time (relay open/relay closed time) button to set an ON and OFF duration for the
relay. The most common uses for this are misters and curtain machines.
The ON time is the duration a relay is active. The ON indicator lights up when this mode is selected.
The OFF time is the duration a relay is inactive. The OFF indicator lights up when this mode is
selected. The duration is set in hundredths of a minute. See the example below.
Toggle to ON to set the ON time for the relay. The digital display will show the current setting, use the
Up or Down buttons to adjust the duration the relay will be closed (active).
Toggle to OFF to set the OFF time for the relay. The digital display will show the current setting, use
the Up or Down buttons to adjust the duration the relay will be open (inactive).
The PEC+ layout is shown. The SEC-HD+ has only three relay stages. You must press OK
after each change to save the settings.
The STAGE MODE indicator at the bottom right of the panel glows green when
you are in stage mode.
On the PEC+, the Stage 1 to 4 indicators light up if two inlet actuators are
connected to the control. If only Stage 1 and 2 are illuminated, only one inlet
actuator is connected. If no indicators are lit up in the left column, no inlet
actuators are connected.
On the SEC-HD+, the Stage 1 and 2 indicators light up if an inlet actuator is
connected to the control. If no indicators are lit up, no inlet actuators are
connected.
The SEL button scrolls through the stages and the Alarm Hi/Lo. The indicators
in the left column light up when you select the corresponding stage. If you scroll
past your desired stage, keep scrolling through the stages by pressing SEL until
you reach it.
Heat or cool
You must designate a relay stage as either heat or cool. To do this, press the
H/C button. The HEAT indicator lights up when you assign the stage as ‘heat’.
The COOL indicator lights up when you assign the stage as ‘cool’. You cannot
assign a relay as a ‘heat’ or ‘cool’ stage if it has been assigned to an actuator.
Example: If you set the ON time to 100 and the OFF time to 500, the relay will be active for one
minute, then inactive for five minutes. When the temperature rises above the set point for a cooling
stage (falls below for a heating stage), the relay will be active for one minute, then inactive for five
minutes. After the five minutes, the control does a check; if the temperature is still above the set point,
the relay will be active again for one minute, then inactive for five minutes.

PLUS user manual Actuator mode
Actuator mode
Calibrating actuators
Each time you place the jumper over the ACTUATOR PRESENT IN pins (see Figure 11 on page 23),
the actuator will be calibrated. During calibration, the actuator opens, pauses, and then closes. The
inlet should open completely then close completely if it is operating properly.
If the calibration procedure stops after closing for the first time, or fails to position, the feedback signal
is not connected correctly. Try reversing the positive and negative feedback wires. If this does not work,
the potentiometer may be defective. Call your dealer for further assistance.
To recalibrate an inlet, remove the actuator jumper, and then replace it on the ACTUATOR PRESENT
IN pins. The actuator will recalibrate when you replace the jumper.
You can position an inlet manually provided the inlet has calibrated correctly. By adjusting the minimum
position setting, you can manually set the position of the inlet. The inlet will stay at this position until you
change the setting. Follow these steps to position the inlet manually.

PLUS user manual The growth curve concept
The growth curve concept
The growth curve allows you to select a period where the temperature set points in a zone or room are
adjusted automatically.
The growth curve set points are group set points. In other words, the individual set points for the
variable and fixed stages will be adjusted without losing the relationship between these stages. This
extremely powerful feature allows ventilation strategies to be put in place. Set points will change as
they should, but the relationship between stages will remain consistent.
You can use the growth curve to automatically change the set points for the stages in each step. Once
you program the growth curve, the control makes the changes to the set points once every 24 hours.
The PLUS control has an internal timer that counts 24-hour periods (days). The count begins when the
control is first powered up. In the event of a power interruption, the day count will be retained, but the
time elapsed in the current day will be reset to zero. You can reset the day count to zero by restoring
the factory settings (see Restoring factory settings on page 13)
The growth curve proportionally changes the current settings towards the next growth curve point over
the duration for the current set point. During the seventh growth curve point, the set point remains
constant. When the seventh growth curve point is complete, the growth curve restarts at step 1 with the
step 1 settings. This is shown in the graph below.
170057 rev 13 9
The growth curve concept Phason
Setting the growth curve
The G.C. MODE indicator in the bottom right of the panel glows green when you are in this mode.
The growth curve is not active when the control is shipped from the factory. The growth curve activates
when the duration for step 1 is set to a value above zero. Follow the steps below to set up the growth
curve:
1. Press Mode until the G.G. MODE indicator is lit.
2. Press GC Select to select the step you want to modify. One of the seven indicators will glow red to
show which step you are modifying.
3. Press Up or Down to adjust the temperature for the step. The TEMP indicator in the status bar will
be lit up and the digital display will show the setting.
4. Press Temp/Duration to change to the duration setting. Press Up or Down to adjust the duration
for the step. The TIME indicator in the status bar will be lit and the display shows the setting.
5. Press OK to save the settings. The display will flash
Acc to show the changes have been accepted.
6. Repeat the process for all seven steps of the growth curve. Press Mode when you have finished
configuring the growth curve.
You can verify the growth curve is active by watching the G.C. MODE indicator while displaying the
ambient temperature. If the indicator flashes, the growth curve is enabled—if it is off, it is not enabled.
Growth curve tips
• Keep a record of the growth curve settings. See the Growth curve setup worksheet on page 35.
• ALL seven temperature set points must be set, and all seven time intervals must be set to values
greater than zero or the control will not operate properly.
10 2005-04-13
PLUS user manual The growth curve concept
• You can make changes to all settings on the growth curve after it has been activated. If you make
changes to a setting that has already passed in the growth curve cycle, the change will not take
effect until the growth curve restarts.
• You cannot set a new duration for an active step that is less than the time that has elapsed for that
step. This will cause the growth curve to proceed to the next step.
• Press GC Select while displaying the ambient temperature to observe the current step of the
growth curve and the number of days until the next step.
• When you set up the growth curve, set the step 1 temperature equal to the Temp SP for VSP-1.
The Temp SP for VSP-1 is the target temperature.
• Set the last duration for the last step for a longer period than you will need. This will allow you time
for unexpected delays, cleaning, or other activities before the growth curve restarts its cycle. If the
animals leave earlier than expected, you can always reset the growth curve at step 1.
• When new animals enter the room, you may want to restart the growth curve at the beginning.
Follow this procedure to restart the growth curve:
1. Press GC Select while the ambient temperature is displayed and then verify the seventh
growth curve indicator is lit.
2. Press Mode until the G.C. MODE indicator lights up.
3. Press GC Select until the growth curve indicator lights up.
4. Press Temp/Duration and note the duration.
5. Press Down until the duration is 0 and then press OK. This causes the current growth curve
step to complete. The growth curve will restart at step 1.
6. Press Mode until the G.C. MODE indicator lights up.
7. Press GC Select until the seventh indicator lights up.
8. Press Up and adjust the duration to the previous setting (procedure 4).
9. Press OK to save the setting.
10. To verify the growth curve has restarted, press Mode until the ambient temperature is
displayed. The G.C. MODE indicator will flash indicating the growth curve is active.
11. Press GC Select to verify the current growth curve step and it’s duration.
• If you change any of the non-growth curve temperature settings while the growth curve is active,
when the growth curve restarts after step 7, the settings will not return to their original values.
Deactivating the growth curve
• Reset all durations to zero starting at step 7 and working to step 1
• Once the last duration is set to zero and Mode is pressed to exit the growth curve, the G.C. Mode
indicator will shut off. This indicates the control is operating in conventional mode. Reset the control
as indicated in the Stage Mode and Variable Speed Mode sections.

Surge suppression
It is not possible to internally protect this product completely from the effects of power surges. We
recommend that surge suppression devices be installed. Power surges can be the result of external
influences (lightning, utility distribution problems), or they may be generated internally (by starting and
stopping inductive loads such as feed mills). See your electrical contractor for specific
recommendations. The user's lack of such precautions acknowledges their willingness to accept the
risk of such loss or injury.

Three-phase wiring
When you wire the PLUS control to a three-phase system, wire the control power and the variable
speed stages to the same phase, as shown in Figure 6 below.
DO NOT wire the PLUS control and the variable speed fans with different phases. If you wire the

Installing the PLUS control Phason
Connecting an actuator (continued)
In a typical installation, a linear actuator is connected to the inlets with a network of cables and pulleys.
These inlets are generally small and are located in the ceiling or walls. They are usually spring loaded
to help close the inlet.
In other installations, larger inlets can be connected to the actuator directly or with a linking arm. A
system operates with the most precision when using the largest amount of stroke that is feasible with
the actuator.
The actuator must have limit switches and a feedback potentiometer. Most linear actuators are
available with internal adjustable limit switches and potentiometer feedback. A 10k Ohm, ten turn
feedback potentiometer works best, but it can range between 1k and 20K Ohms.
Phason suggests using Grainger part # 5A652, von Weise (Fasco) model # V00099BA76, or equivalent
DC linear actuator which can be used with a DC power supply (Phason part # 124-0). You may require
a bracket to prevent the actuator arm from rotating while it is extending.
The DC power supply should have a snubber filter installed to protect the relay contacts from excessive
electrical noise and transients.

PLUS user manual Installing the PLUS control
Connecting temperature sensors
The PLUS control can operate with one to four temperature sensors installed. The control detects when
a sensor is installed and averages the temperatures before displaying it. A sensor can be installed in
any of the four terminals.
• Do not run the probe 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.
Connect the temperature sensors to the control as shown in Figure 14 below.

Figure 14: Connecting a temperature sensor
Extending the sensor
• You can extend temperature probe cables to lengths of up to 500 feet.
• Use two-wire 18 AWG jacketed cable. Phason recommends Belden # 9408, Alpha # 5052, or an
equivalent. Extension cable is also available from Phason. For more information, contact your dealer
or Phason.

B Strip the ends of the wires and then twist them together.
C Solder the wires together using rosin-core flux solder—DO NOT use acid core solder.
D Slide the heat shrink tubing over the solder joints.
E Shrink the tubing using a heat gun.
F Your connection should look like this.
Networking the control
To connect your PLUS controls to a computer, you need to purchase the PLUSWARE software and
install it on your computer. You also need to connect all your PLUS controls to each other and the
computer.
You can program each control with an identification number so it is easier to recognize the controls
when using the computer. See Control ID on page 13 for programming instructions.
Communication cable requirements: 100 Ω, CAT 3, two-pair, unshielded twisted-pair cable
Termination resistors
The last control on a communication channel must have the termination resistors or a termination
module installed. If you have already removed the termination resistors from the last control, you can
order a termination module (part number 210510) from your dealer.
Remove the termination resistors on all the other controls by cutting the resistor leads with wire cutters.
Only one end of each resistor needs to be cut to disconnect it from the circuit.
The termination resistors are labelled R9 and R10.

Wiring the network
The computer must have a serial port to communicate with the PLUS control. The RS-485A Converter,
which is available from your Phason dealer, is required to connect the computer to the PLUS controls.
For information about wiring the network using the converter, see the RS-485A Converter installation
guide.
Connect the controls to the network as shown below.
Connect all the PLUS controls to a single branch or line.

Phason Care and maintenance
Care and maintenance
Moisture will not cause a problem with the control if you take proper care during installation. The
control's enclosure is made of fire retardant plastic and sealed with a rubber gasket. The sensor entry is
sealed with a liquid-tight cable connector.
Use caution when washing the room with a high-pressure washer. DO NOT direct a high-pressure
washer at the control. To clean the surface of the control, wipe it with a damp cloth.
CAUTION:
Turn off the power before cleaning or servicing the
control.
Maintenance
• After the first two weeks of operation, remove the cover from the unit and check inside for moisture.
Be sure to turn off the power to the control before opening the cover.
• If there is moisture present, wipe it out with a dry cloth and check the cable entry points and rubber
gasket for proper sealing.
• If the cable connectors are not sealing, apply RTV or Silicon II sealant around the cable.
Some silicone sealants release acetic acid while curing. This can cause corrosion and
damage the control. Let the silicone cure completely (one to three days). Failure to do this
may damage the control and void the warranty.
• Check the control again after two weeks to verify it is sealing properly.
• Open and inspect the control for moisture once a year. Proper care and maintenance will extend
the life of the control.
Additional tips
A field test board (part number 170042) is available that enables you to quickly test your PLUS
•
series control to ensure it is wired correctly. The test procedure verifies the variable speed and relay
stages are operating properly by testing each stage in order.
• The field test board plugs easily in place and allows you to move through the tests by pressing the
button on the board. After you have completed the testing, simply remove the test board and fasten
the cover back on the control. You do not have to turn the power off while installing or removing the
test board.
• If you are using a single speed fan and want to take advantage of the variable speed 1 and 2
stages, set the variable speed minimum idle to 100%. This allows you to use the variable speed 1
and 2 stages like regular relays, with the set point being the idle off parameter.
