21040012 9
Chapter 1: Introduction
Some features require additional sensors or equipment. Water usage requires a water meter with pulse output. Humidity monitoring and control requires a Relative Humidity Sensor. Additional zones or outdoor temperatures require additional temperature probes.
A powerful four-zone controller
The Supra automatically monitors and controls the temperature in up to four separate zones. The Supra controls the temperature in each zone by operating ventilation equipment such as fans, heaters, inlet actuators, curtain machines, or other equipment according to your programmed settings.
The Supra has two seven-step growth curve programs you can configure for up to 250 days. This powerful feature automatically adjusts the temperature set points over time to control the temperature in a room or zone.
More than just temperature control – monitor water usage and control humidity
Not only can the Supra monitor and control temperatures using ventilation equipment, it can monitor water usage and control humidity.
The Supra’s pulse counter allows you to connect a water meter (with pulse output) and monitor water usage. With an optional Relative Humidity Sensor, you can monitor humidity and automatically adjust your ventilation control strategy accordingly.
Temperature setback for day/night temperature control in greenhouses
Temperature setback allows you to automatically change the temperature set point for specific periods during the day. When temperature setback is enabled, the Supra subtracts the setback amount from the set point. At the end of the setback period, the Supra returns to the normal set point.
Temperature setback is ideal for maintaining different method (DIF) and in greenhouses.
Security and peace of mind
The Supra has a five-level PIN (personal identification number) security system. Each level has access to different menus of the Supra. When you enable security, users must enter their PIN before they can access a specific menu or function. This allows you to track who makes changes to your system and its settings.
The Supra is compatible with most alarm sirens and alarm systems. You can connect the Supra to an alarm siren or other external alarm system. The customizable list of alarm settings allows you to choose which alarm conditions you want to be notified about. The Supra automatically logs all alarm conditions.

If you do not install external surge suppression devices, you risk damage to
the electronics inside the Supra, which may cause the Supra to fail.
Because it is not possible to completely protect this product internally 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: Installation
What you need to know before installing the Supra
1. Read Understanding power surges and surge suppression below.
2. Using the installation worksheets in Appendix D (starting on page 123), list all the equipment you
want to control using this Supra. Install the equipment and make your electrical connections according to the sheet.
3. Using the configuration worksheets in Appendix E (starting on page 125), decide which relays
you want to use for each piece of equipment, and how you want the equipment organized by zone in the Supra. You can connect more than one piece of equipment to a single relay as long
as the total amps do not exceed the relay’s limit. For more information about the control
ratings, see Supra electrical ratings on page 20.
Understanding power surges and surge suppression
Power surges can be caused by external 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. 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 recommends 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.
21040012 18
What you need to know before installing the Supra
Some power contactors include snubber filters. For more information, read
Using power contactors to increase the capacity of relays on page 20.
For more information about snubber filters or other Phason accessories, see
your dealer or visit www.phason.ca.
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.
Phason highly recommends installing filters on all inductive loads.
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 (part number 127-0) are intended 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.
Install a filter in parallel with the load, as shown in the following example.

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 (load) is within the limits. 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 the FLA rating. Actuators require two relays: one for opening, one for closing. You can connect a maximum of two actuators. Tip: You can increase the load capabilities of the Supra´s variable stages 3 and 4 by connecting slave units. Each slave unit increases the current capacity of the stage it is connected to by 20 A. For more information, read Slave units on page 11.
Supra electrical ratings
Using power contactors to increase the capacity of relays
Phason’s 240-volt power contactors are heavy-duty relays that allow you to increase the load handling capability of control relays. Power contactors are ideal for secondary ventilation fans and electric heaters.
Phason’s power contactor relays have the following electrical ratings.
Coil: 10.2 mA at 240 VAC Contact: 25 A at 240 VAC; resistive
2 HP at 240 VAC, 1 HP at 120 VAC; motor, power factor 0.4 1300 W at 120 VAC; tungsten
Phason offers three power contactor options.
Power contactor relay (model PC-240) – includes power contactor relay and mounting hardware
for easy mounting in an enclosure.
Power contactor kit (model 122-1) – includes power contactor relay, on-off-auto switch and
label, snubber filter (reduces electrical noise), and mounting hardware for easy mounting in an enclosure.

Mounting the Supra
1. Select a location for the Supra. 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
swing it open.
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.
21040012 23
Chapter 2: Installation
Use the electrical knockouts for bringing wires or cables into or out of the Supra enclosure. Do not make additional holes in the enclosure; this can damage the watertight seal or control components and void the warranty.
The Supra’s built-in diagnostic tests are useful for testing your equipment after installing and configuring it. For more information, read Performing diagnostic tests on page 105.
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.
Connecting equipment to the Supra
Follow all instructions when installing the Supra and connecting equipment to it.
Connecting actuators
You can connect up to two actuators to a Supra. Actuators are used for control elements that are not OFF or ON. Instead, they vary by a percentage. For example, inlets can be opened various distances from 0 percent to 100 percent.
Typically, linear actuators are connected directly to the inlets, or by cables and pulleys. Inlets are generally located in the ceiling or walls. Inlet systems are usually spring loaded to help close the inlet, or counter weighted to help open the inlets.
Each actuator you connect requires two relays: one for extending the actuator arm (opening the inlet), and one for retracting the arm (closing the inlet). You can connect the actuator to any of the available relays, but side-by-side relays are recommended.
Feedback potentiometers
Each actuator you connect must have a feedback potentiometer. The feedback potentiometer, which you connect to one of the Supra’s two feedback terminals, lets the Supra 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 can control the actuator.

1/3 HP at 120 VAC, 1/2 HP at 230 VAC
360 W tungsten at 120 VAC
If you are connecting an actuator that exceeds the relay ratings, you must install a power contactor. For more information, read Using power contactors to increase the
capacity of relays on page 20.
Refer to Appendix D: Installation worksheet on page 123 and Appendix E:
Configuration worksheets on page 125 when installing actuators.
When connecting a feedback potentiometer, connect it to ACT1 for actuator 1
and ACT2 for actuator 2.
If you are unsure of the potentiometer wiring for your actuator, see Determining
correct actuator feedback wiring on page 121.
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.
If you are measuring AC power with a DMM, note that if a limit switch opens the
circuit, the DMM measures voltage after the relay switch even if the relay is open.
DC-powered actuators, filters, and power supplies
If you are connecting DC-powered actuators, you must connect snubber filters to absorb the transient energy the motors generate. Installing filters helps extend the life of Power Block relays. For more information, read Reducing electrical noise using filters on page 19.
Phason offers two models of DC-actuator power supplies. Both models are CSA-approved and
include snubber filters.
DC power supply (124-0) – includes +18 and –18 VDC fused outputs and a snubber filter, all
mounted in an enclosure.
DC power supply (124-1) – includes +18 and –18 VDC fused outputs and a snubber filter, all
mounted in a large enclosure. The enclosure has room for two power contactor kits (PC-240 or 122-1).
A 36-V DC-powered actuator positions more slowly and accurately with an 18-V power supply, but has less thrust. For more information about power supplies or other Phason accessories, see your dealer or visit www.phason.ca.

Connecting equipment to the Supra
If the Supra’s circuit board does not have the jumper, you cannot use the sensor Make sure the jumper is on the two left pins before switching on the power to
the Supra. If the jumper is not in the correct position when you switch on the power, the sensor will be damaged. This will void the warranty.
The water meter must measure one unit or greater per pulse. Also, the units per pulse must be a whole number; the Supra does not accept fractions or decimals. For example, 1 gallon per pulse or 10 gallons per pulse would work; 0.5 gallons per pulse or 1.5 gallons per pulse would not work.
To connect a Relative Humidity Sensor
1. Place jumper JA1 on the two left pins as shown below.
2. Connect the sensor to the ANALOG terminal as shown below.

What you need to know before configuring the Supra
This chapter does not explain set points, idle speeds, or other settings. For information about those settings, read Chapter 4: Programming on page 64.
Chapter 3: Configuration
What you need to know before configuring the Supra
Configuring the Supra means telling it what equipment it will be controlling, and to some extent, how it will be controlling that equipment. For example, the Supra has 12 relay stages. You need to tell the stages if they will be controlling curtains, heating or cooling elements, or timed events. In addition, you need to tell the stages in which zone (1, 2, 3, or 4) they will be controlling those elements.
In addition to configuring the variable and relay stages, configuration also includes information that you set once or change very rarely, for example, the name of the Supra.
Before you begin configuring the Supra, make sure:
It has power All equipment has been properly connected to the correct terminals. You know which equipment is connected to which relays and variable stages
How zones work
Because the Supra is a four-zone controller, you can divide your facility into real or imaginary zones – areas that can each be controlled independently of the others. Part of the configuration process is assigning relay stages and variable stages to zones (only one zone per stage).
A zone defines an area set off as distinct from surrounding or adjoining parts. Zones might or might not be separated by walls. For example, a large room could be divided into two zones to provide better control response.
Example 1: two rooms, two zones
You have a large finisher barn that is divided into two rooms. You have a forced-air ventilation system consisting of fans and inlets. You will use one Supra to control both rooms, one zone per room. The configuration could be as follows:

SET UNIT NAME Name: Phason Supra Version: 2.00 Address: 50B61AC8
Identifying the Supra
To identify a particular Supra, you need to give it a meaningful name, such as West Barn or Finishing
Room. This is even more important when you have several Supras networked together.
If you move the Supra, or change how you use the area controlled by the Supra, you might want to change the name to something more descriptive.
Two additional pieces of information can be found on the Set Unit Name screen.
The version number tells you which version of firmware the Supra has. Phason constantly improves and adds new features to their products. If there are new features available, you can upgrade the Supra using firmware updater. For more information, read Supra firmware updater on page 12.
The address is a unique number generated for the Supra when it was manufactured. If you have a network of Supras and use SupraWare, you will need to remember this number. For more information, read the SupraWare user manual.
To give the Supra a name
1. From the Main Menu, select Maintenance (2).
2. From the Maintenance menu, select Set Unit Name (5).
The display should look like the following example.
3. Scroll to the second line and then press ENTER.
4. Enter the name (maximum 14 characters) for this Supra. For more information, read Entering

beginning of the line. To cancel the change, press BACK.
5. Press BACK twice to return to the Main Menu.
Configuring the startup timer
The Supra’s startup timer allows you to delay the startup of each Supra’s loads when the controls return from a power failure. Configuring the timer allows you to distribute the initial startup load the backup generator must handle, allowing you to use a lower-capacity, more-economical generator.
You can configure the startup timer to delay starting the Supra’s loads from 0 to 59 seconds. For example, say you have 4 Supras in your facility and you set the delays to 0, 10, 20, and 30 seconds.

Changing the type of temperature probe
The Supra comes with a Phason 3K temperature probe – the standard for most Phason controls. If you want to connect a 1K probe, you need to tell the Supra that you have connected a different type of probe.
By default, the Supra is set to normal for 3K temperature probes. You need to select the type of probe only if you are not using a standard Phason 3K temperature probe. A 1K probe is typically used in (embedded inside) heat mats, such as, Master Mat.

Chapter 3: Configuration
Replace damaged probes as soon as possible. If a probe is damaged, unless you have temperature averaging enabled, the Supra automatically selects the next active temperature probe. For more information, read Configuring temperature
averaging below.
When averaging is on, if a probe is damaged, the Supra uses the temperature from the remaining averaged probe(s) for the zone.
If all of the averaged probes for a zone are damaged (in other words, there are no probes available), the Supra switches all the heating elements off and switches all the cooling elements on 100% for that zone.
Probe 1 Normal Probe 2 Normal Probe 3 Normal Probe 4 Normal
To change the type of temperature probe
1. From the Main Menu, select Maintenance (2).
2. From the Maintenance menu, select Temperature Probe.
The display should look like the following example.
3. If you are using a 1K temperature probe, scroll to the line corresponding to the zone where you
installed the probe and then press ENTER.
4. Press + or – to change Normal to Special and then press ENTER.
5. Repeat steps 0 and 4 for each 1K probe you installed.
6. Press BACK twice to return to the Main Menu.
Configuring temperature averaging
Temperature averaging allows you to take temperature readings from up to four probes and average the values.
For example, say you have a large room controlled as a single zone. Because the room is large, you want to have temperature readings from two different ends of the room. You enable temperature averaging and then set up zone 1 to average probes 1 and 2. If probe 1 reads 72.0°F and probe 2 reads 74.0°F, the Supra uses the average of 73.0°F as the temperature for the zone.
44 Phason
Configuring the main control functions
Use the Temperature averaging worksheet on page 127 when configuring temperature averaging.
Averaging is: Off
Another advantage of temperature averaging is that it prevents the Supra from using an undesirable probe if the one for a zone becomes damaged.
For example, you have four probes connected to the Supra and are using four zones. Temperature averaging is off. If probe 3 is damaged, the Supra uses the probe for zone 4 to control zone 3. If the probe for zone 4 is a heat mat probe, this can cause the ventilation equipment for that zone to operate undesirably. To prevent this, use averaging to isolate dissimilar zones.
With averaging, you could set up the Supra to average one probe for each zone as follows: zone 1 ­probe 1; zone 2 - probe 2; zone 3 - probe 3; zone 4 - probe 4. In this case, if probe 3 is damaged, the Supra does not default to probe 4; instead, it switches off all the heating elements and sets all the cooling elements to 100% for that zone.
Temperature averaging and high/low temperature alarms
The Supra generates an alarm condition if any averaged probe measures a temperature that is an alarm condition.
For example, a Supra has four probes averaged and alarms enabled for each of them. The low temperature alarm setting is 65°F. Probes 1, 2, and 3 read temperatures of 68°F, but probe 4 reads 64°F. Because probe 4 reads a temperature that is below the low alarm setting, the Supra gives a low temperature alarm, even though the average temperature is 67°F, 2°F above the low alarm setting.
To configure temperature averaging
1. From the Main Menu, select Maintenance (2).
2. From the Maintenance menu, select Averaging On/Off.

Configuring the control stages
Configuring the control stages means selecting where, how, and what the variable stages and relays will be controlling.
For each variable stage or relay, you have the option to enable tunnel mode (set tunnel turn off to
yes). Tunnel mode is valid only for variable stages and relays configured as cooling elements
(including actuators and curtains). If you enable tunnel mode for heating elements, it has no effect.
For more information about tunnel mode, read Programming the tunnel mode set point on page 70.
Variable stages
The Supra has four variable stages that you can configure as one of three options.
Heat – the stage controls a heating element. Cool – the stage controls a cooling element. This is the default. Unassigned – the stage is always off.
Relay stages
The Supra has 12 relay stages that you can configure as one of several options.
Unassigned – the relay is always open (off). This is the default. Actuator – the relay controls a cooling element called an actuator. Actuators require one relay for
opening and one for closing.
Heat – the relay controls a heating element and switches on when the temperature falls below
the temperature set point. An example of a heating element is an electric heater. Temperature­based duty cycles are also included in this configuration.

Curtain – the relay controls a cooling element called a curtain machine. Curtains require one
relay for opening and one for closing.
Duty Cycle (time-based) – the relay controls an element that operates for specific durations (on
duration and off duration) during certain hours of the day. An example of a time-based duty
cycle element could be a feed auger.
Timed Event – the relay controls an element that switches ON or OFF at certain hours of the
day, regardless of the temperature or other conditions. An example of a timed event element could be lights.
Variable DC outputs
If you have a Variable DC Expansion Kit installed in the Supra, you can configure an additional four variable stages. The variable 0 to 10 VDC outputs have the same options as the normal variable stages.
For more information about the expansion kit, read Variable DC Expansion Kit on page 12.
Slave units
If you have Single-Phase Slave (PSU-20) units connected to the Supra, you do not need to configure any additional items. When a PSU-20 is connected to variable stage 3 (VR3), it follows the configuration and settings for variable stage 3. When connected to variable stage 4 (VR4), it follows stage 4.

Calibrating actuators
After configuring the actuator relays, you need to calibrate the actuators. Calibrating the actuator lets the Supra know the position of the actuator when it is fully extended and fully retracted. The Supra uses the limits to define the range of motion it uses to position the inlets. These limits tell the Supra how much to adjust when you want the actuators, for example, only 25% extended.
There are two stages to calibrating actuators. Stage 1 is testing the open and close functions and setting the limit switches. Testing an actuator really means testing the inlets it is controlling. Stage 2 is calibrating the actuator. In the following steps, we assume the actuator is positioning an inlet.

Chapter 3: Configuration
Calibrating actuators takes several minutes. You can stop the calibration process at any time, but if you do, the Supra will not be able to properly control the inlets.
If the actuator stops after moving in the close direction, or if it fails to position
the inlet properly, the Supra is not receiving a proper feedback signal. This can be incorrect wiring or a defective potentiometer. Correct this problem and then restart the calibration at step 1. For more information read, your actuator’s installation guide and Connecting actuators on page 24.
If the calibration fails (for example, if the actuator jammed), the display shows
the reason for the failure. The date and time the actuator was last calibrated does not change. Check the alarm messages and then look up the problem in

Testing the configuration
After configuring all the control elements (variable stages relays, and so on), test the Supra to make sure the configuration is correct. In other words, make sure what you think is connected to a particular relay or stage is actually connected to that relay or stage.
You can test the configuration by using the diagnostic feature of the Supra. The diagnostic feature allows you to operate the equipment, regardless of temperature or time. As you operate each piece of equipment, visually check to see if that equipment is doing what you tell it.
For example, when you switch on variable stage 1 at the Supra, does the fan or heater you think have connected to that stage switch on? When you switch it off, does the fan or heater switch off?
For more information about the diagnostic test, read Performing diagnostic tests on page 105.

Configuring hysteresis
Hysteresis helps prevent damage to the relays, variable stages, and equipment connected to them by preventing the stages from switching on and off rapidly when the temperature is hovering close to the set point.
For example, a household thermostat might turn on a furnace at 68 °F when the house is cooling down, but turn it off at 72 °F when the house is warming up. The difference between these two values is the hysteresis.
To set hysteresis values
1. From the Main Menu, select Maintenance (2).
2. From the Maintenance menu, select Hysteresis (7).
The display should look like the following example.
3. Scroll to the second line and then press ENTER.

The Supra interprets the last digit as a decimal. For example, to enter 0.5°F, press 05.
Actuators have three hysteresis values: one for temperature, one for position, and one for duration. For more information, read the Hysteresis worksheet on page 129.
For de-icing to work properly, you must have a temperature probe connected to
the OUT TEMP terminal. For more information, read Connecting temperature
probes on page 31.
If de-icing is enabled and there is no outdoor probe (or it is damaged), the Supra
operates as if the outdoor temperature is below the de-icing temperature.
4. Enter the temperature using the numbers on the keypad, or press + or – to adjust the hysteresis
and then press ENTER.
5. Scroll to the next line.
6. Repeat steps 4 and 5 for each setting.
7. Press BACK twice to return to the Main Menu.
Configuring de-icing
The Supra’s de-icing feature helps keep variable-speed fans from icing up if the outdoor temperature is too cold. When de-icing is enabled, variable-speed fans start at full speed before dropping to the idle or normal speed. Configuring de-icing means setting the temperature at which de-icing starts, setting the duration it lasts, and selecting which variable speed fans to de-ice.
For example, if you set the de-icing temperature to 32°F and the duration to 3 seconds, when the fan starts up, it automatically runs at full speed for three seconds before dropping down to its normal speed (whatever the normal speed should be for the current temperature in that zone).

Configuring the pulse counter
If you have a water meter connected to the Supra’s pulse counter terminal and will be monitoring water usage, you need to tell the Supra how much water (in litres or US gallons) goes through the meter for each pulse the meter puts out. The Supra uses this information to convert the pulses to water usage values.
For example, let’s say your water meter puts out 1 pulse for every 10 gallons of water that goes through it. If the Supra received 125 pulses from the meter during the day, you used 1250 gallons of water.
To configure a pulse counter
1. From the Main Menu, select Settings (1).
2. From the Settings menu, select Water Meter.
The display should look like the following example.
3. Scroll to the second line and then press ENTER.

Chapter 4: Programming
What you need to know before programming the Supra
The difference between “programming” and “configuration” is that configuration is information
that you set once, or change very rarely; programming is information you change more often.
Programming the Supra means telling the control what you want it to do and when you want it done. For example, for a single-speed fan set for cooling, you might say: “Switch on when the temperature rises above 80°F.”
Before you begin programming the Supra, make sure:
It has power All equipment has been properly connected to the correct terminals. You know which equipment is connected to which relays and variable stages All variable and relay stages have been properly configured and tested. For more information,
read Chapter 3: on page 37.

Chapter 4: Programming
Use the Group set point worksheet on page 131 when setting up groups set points.
Programming the zones
Programming the zones means entering the target temperatures for each zone. There are two options for the zone temperatures:
Group set points (below) Growth curves (on page 67)
You can set up both group set points and growth curves. If a growth curve is enabled for a zone, the control uses the growth curve settings. If there is no growth curve for a zone, the control uses the group set points.
Other options
In addition to the group set points and growth curves, you can program three optional features:
Tunnel mode set point (en page 70) Temperature setback (on page 71) Humidity control limits (on page 73)
Setting the group set point
A group set point is the desired or target temperature for a zone. The individual set points for each variable and relay stage will be adjusted relative to the group set point for that zone. Make sure you
set the group set point before setting the individual set points.
For example, say the group set point for zone 1 is 80°F, a variable-stage fan set point is 5 degrees higher (85°F), and a single-stage heater set point is 7 degrees lower (73°F). If you lower the group
set point to by 5 degrees to 75°F, the set points for the fan and heater will also be lowered by 5
degrees to 80°F and 68°F respectively.
Once a group set point is set, it remains at that temperature until you change it, or until an enabled growth curve adjusts it.
To program a group set point
1. From the Main Menu, select Settings (1).
2. From the Settings menu, select Group Setpoint (1).

Programming the zones
The Supra interprets the last digit as a decimal. For example, to enter 80.5°F, press 805.
Zone 1 85.0°F Zone 2 85.0°F Zone 3 85.0°F Zone 4 85.0°F
The display should look like the following example.
3. Scroll to a zone you want to change and then press ENTER.
4. Enter the temperature using the numbers on the keypad, or press + or – to adjust the set point
and then press ENTER.
5. Repeat steps 0 and 4 for each zone you want to set up.
6. Press BACK twice to return to the Main Menu.
Programming growth curves
A growth curve is an extension of the group set point concept. The growth curve automatically adjusts the temperature set points over time to control the temperature in a room or zone. It is called a growth curve because it adjusts the set points as the animals grow.
For example, in hog production, newborn piglets require a high temperature for comfort and health. As they grow older, they need a steadily lower temperature. Using the growth curve, you can have the Supra automatically adjust the temperatures. For example, start at 76°F for 1 day, drop to 74°F for 1 day, then to 71°F for 21 days, 68°F for 14 days, and so on.
You can have up to seven steps in a growth curve. Each step has a start day and temperature set
point. The Supra automatically calculates the temperature set points for the days between the steps
and adjusts the set points at midnight each day. Individual set points for the variable and fixed stages are adjusted relative to the growth curve temperature for that particular day. This is an extremely powerful feature because it lets you put fan and heating strategies in place once, and then adjust them automatically over time.

In the following example, step 2 has a duration of 10 days. The difference between the starting set point (86.5°F) and the starting set point for the next step (85°F) is 1.5°F.
The Supra divides the temperature difference by the duration 1.5 ÷ 10=0.15 and then automatically adjusts the set point by 0.15°F each day for 10 days.
You can define two growth curves: Growth Curve A and Growth Curve B. This lets you control two different areas of your facility with independent set points.
You cannot define two growth curves for the same zone. If all zones are controlled by a single growth curve, use Growth Curve A.
Growth curve status
There are several options for the growth curve status:
Disabled – the growth curve is ignored. When enabled, the growth curve starts at day 1. Enabled – the growth curve is active for the zones specified. Suspended – all set points stay at their current values. The growth curve remains on its current
day until it is enabled again. When enabled, it starts where it left off.
Override – the growth curve advances one day at a time (in other words, the clock still
advances), but the control uses the group set point instead of the growth curve.
When enabled, the control uses the growth curve set point for that day. This can cause a sudden change in temperature if the group set point is very different from the growth curve set point.

Programming the zones
If you are programming your growth curve a few days before you want it to start,

Programming the temperature setback
Temperature setback allows you to automatically change the temperature set point for a specific period during the day. The temperature setback can be from 1.0 to 25°F (0.6 to 13.9°C). When the setback is enabled, during the selected hours of the day, the Supra subtracts the temperature setback amount from the set point. At the end of the setback period, the Supra returns to the normal (group or growth curve) set point.
Temperature setback works for both group set points and growth curves. There are two separate setback groups: A and B. Having two setback groups allows you to have different setbacks for different zones or times of the day.
Using setback for day/night temperature control in greenhouses
Different method (DIF) is a means of maintaining different day/night temperatures in greenhouses. DIF helps control plant height and growth.
DIF is calculated by subtracting the nighttime temperature from the daytime temperature. Higher day temperatures give a positive DIF and promote growth. Lower daytime temperatures give a negative DIF and slow down growth. Negative DIF helps control plant height.
Using temperature setback, you can maintain a lower temperature set point during the critical dawn hours, and then return to the normal (group or growth curve) set point later in the day.
Example 1
Example 1 shows how you can use the two setback groups (A and B) to have two different setback values for different times in the same zones.
The setback for zones 1 and 2 is 8.0°F between 6:00 AM and 12:00 PM, and 5.0°F between 12:00 PM and 9:00 PM. If the group set point for zones 1 and 2 is 78.0°F:
From 6:00 AM to 12:00 PM, the adjusted set point
will be 70.0°F.
From 12:00 PM to 9:00 PM, the adjusted set point
will be 73.0°F.
After 9:00 PM and before 6:00 AM, the set point
would be the normal 78.0°F.

Programming the humidity control
If you have installed and configured a humidity sensor, you need to program the humidity compensation. Programming the humidity compensation means setting the humidity factor and the upper and lower humidity limits. The Supra uses these settings to compensate for high humidity levels and it adjusts the ventilation accordingly.
The humidity band is the humidity range in which the Supra attempts to compensate for humidity. The band is defined by the upper limit and lower limit.
The humidity factor is a number between 0 and 10 that determines the amount of humidity compensation. A lower value produces a slight ventilation adjustment, while a higher value produces a greater adjustment.
How humidity compensation works
The Supra uses the humidity band and humidity factor to adjust the ventilation for the zone. At the beginning of the band (the lower limit), very little adjustment is made. As the humidity rises, the adjustment increases. At or above the upper limit of the band, the maximum adjustment is applied.
For example, if the maximum acceptable humidity for your zone is 70%, set the lower limit to 70%. The upper limit could be set for 90% (90% is the maximum allowed and 20% is the minimum difference between the limits). When the humidity is below 70%, the ventilation rate is controlled by the zone’s normal, programmed settings. As the humidity rises above 70%, humidity compensation starts to take effect and the ventilation rate increases. When the humidity reaches 90%, the humidity compensation reaches its maximum adjusted rate.
If the outside air is cooler than the zone temperature, the ambient temperature in the zone drops due to the increased ventilation. This causes the heaters to switch on, which help to dry the air. It is
important to balance this effect with your heating system’s ability to maintain the temperature while
drying out the room. A lower humidity factor starting at a lower humidity level, and spread over a wider band, is better for lower-capacity heating systems.
21040012 73

Before programming the humidity compensation, you must assign the humidity sensor to a zone. For more information, read Selecting a humidity zone on page 60.

78 Phason
Programming the stages
The Supra’s actuator control function requires a potentiometer feedback on the
motor. Using actuator control without a potentiometer feedback can burn out the motor.
If you are not using a potentiometer feedback, use the curtain function to
provide timers for opening and closing. For more information, read Programming
curtain control relays on page 81.
Programming actuators means setting the temperature set points, differential, and position for each stage of the actuator. Each actuator has four stages. For each actuator you are setting up you need to program the:
Minimum set point temperature Minimum position Set point temperature, differential temperature, and position for stages 1 to 4
How actuators work
While the temperature is below the minimum set point, the actuator is closed. When the temperature rises to the minimum set point, the actuator moves to the minimum
position.
As the temperature rises, the actuator has four stages it moves through until it reaches its
maximum open position. This method lets you gradually open inlets instead of fully opening
them when the temperature rises above a single set point.
For example, you might decide to have the actuator open to 40 percent at stage 1, 60 percent at stage 2, 80 percent at stage 3, and 100 percent at stage 4.
However, you do not want the actuator to open directly to 40 percent. That is why there are two temperature settings for each stage. The first setting is the stage set point. This is where the actuator starts opening. The second setting is the differential. This is where the actuator reaches the stage
position.
In other words, “when the temperature is here (stage set point), I want the actuator to start opening. When the temperature reaches here (stage differential), I want the actuator to be at this position (stage position) percent.”

Configuring relays for curtains on page 54.
Programming the curtains means setting the temperature set point, idle band, and idle and run times. Each curtain has six settings:
Set point – the temperature at which the curtain holds its position. Idle band – the buffer around the set point within which the curtains hold their position. Open run time – the duration the curtains open during the OPEN cycle Open idle time – the duration the curtains hold their position during the OPEN cycle Close run time – the duration the curtains open during the CLOSE cycle Close idle time – the duration the curtains hold their position during the CLOSE cycle

Use the Curtain worksheet on page 137 when setting up curtains.
Idle band (+/– 2°F)
When the temperature is within the idle band, the curtain remains in its current position.
Set point (80°F)
Open run (00:30 mm:ss)
If the temperaturee rises above the idle band, the curtain opens for this duration.
Open idle (02:00 mm:ss)
After the curtain opens for the “open run” duration, it holds its position for the open idle
duration.
Time (duration)
Close run (01:00 mm:ss)
If the temperature drops below the idle band, the curtain closes for this duration.
Close idle (01:00 mm:ss)
After the curtain closes for the “close run” duration, it holds its position for the close idle
duration.
How curtains work
Curtains hold their position while the temperature is within the idle band of the set point. For example, if the set point is 80°F and the idle band is 4°F, the curtain holds its position when the temperature is between 78°F and 82°F.
If the temperature rises above the idle band (above 82°F in our example), the curtain opens for the
open run duration. After opening, it holds its position for the open idle duration. If the temperature
is still above the idle band, the curtain again opens for the open run duration and the process repeats.
If the temperature drops below the idle band (below 78°F in our example), the curtain closes for the close run duration. After closing, it holds its position for the close idle time. If the temperature is still below the idle band, the curtain again closes for the close run duration and the process repeats.

Programming heating and cooling elements and temperature­based duty cycles
Heating and cooling elements control the temperature by switching single-stage heating equipment such as electric heaters, or cooling equipment such as misters ON or OFF. Before setting up the elements, make sure you have properly configured the relays. For more information, read
Configuring relays for heating, cooling, or temperature-based duty cycles on page 53.
21040012 83
Chapter 4: Programming
Use the Heating and cooling elements worksheet on page 138 when setting up heating and cooling elements or temperature-based duty cycles.
The relay does not switch ON until a temperature condition has been met. For example, if the temperature rises above 85°F, switch on a mister for 5 minutes and then OFF for 10 minutes. Repeat this until the temperature is below 85°F.

There are two types of heating and cooling element setups: “standard” and “temperature-based” duty cycle. Programming a standard element means setting the temperature set point and selecting Off for the duty cycle. Programming a temperature-based duty cycles means setting the temperature
set point, selecting On for the duty cycle, and setting the on duration and off duration.
How temperature-based duty cycles work
For heating elements
When the temperature is above the set point, the heating element is off. When the temperature drops below the set point, the element switches on for the on duration and then off for the off
duration. If the temperature rises above the set point, the duty cycle switches off and will not switch
on again until the temperature drops below the set point.
For cooling elements
When the temperature is below the set point, the cooling element is off. When the temperature rises above the set point, the element switches on for the on duration and then off for the off duration. If the temperature drops below the set point, the duty cycle switches off and will not switch on again until the temperature rises above the set point.
To program heating or cooling elements (without a duty cycle)
1. From the Main Menu, select Settings (1).
2. From the Settings menu, select Heat/Cool Stages (2).

Programming timed events
Timed event relays control equipment such as lights that need to be switched ON or OFF during certain times of the day. Programming timed events means setting the “on” and “off” times. Timed events must occur in pairs. This means that every time you set a relay to switch on, you must set a time for it to switch off.
Before setting up the timed events, make sure you have properly configured the relays. For more information, read Configuring relays for timed events on page 56.

Programming time-based duty cycles
Time-based duty cycles are a cross between temperature-based duty cycles and timed events. Unlike temperature-based duty cycles, time-based duty cycles occur between certain hours of the day, regardless of temperatures.
Setting up a time-based duty cycles means setting the on duration, off duration, start time, and end
time.
Before setting up the time-based duty cycles, make sure you have properly configured the relays. For more information, read Configuring relays for time-based duty cycles on page 55.
How time-based duty cycles work
The relay does not switch on until the From time (start time). Between the start time and the To time (end time), the relay switches on for the ON duration and then OFF for the off duration. When the time reaches the end time, the relay switches off (if it is not off already) and does not switch on again until the time reaches the start time.
88 Phason
Programming the stages
This section explains how to set up time-based duty cycles. If you want to set up temperature-based duty cycles (duty cycles that operate for specific durations while the temperature is above or below a certain value), see Programming heating and
cooling elements on page 83. If you want to set up elements that turn on and off at
specific times, see Programming timed events on page 86.
Use the Time-based duty cycle worksheet on page 141 when setting up time-based duty cycles.
The relay does not switch on until the “from” time (start time). The relay switches off (if it is not off already) at the “to” time (end time) and does not switch on again until the time reaches the start
time.

Programming the alarm and display settings
After programming the variable and relay stages, you can move on to the alarm and display settings.
Alarms (below) Status screen display (on page 93)
Programming alarm settings
The alarm settings for the Supra determine which alarm conditions are enabled, which are disabled, and their settings. All these work together to determine how and when the alarm relay activates (in other words, signals an alarm condition).
The alarm relay activates if an alarm condition (one that is enabled) is present for longer than the minimum duration. Minimum duration prevents alarms from activating when the temperature rises or drops for just a few seconds. Minimum duration can be between 0 and 10 minutes; setting it to 0 activates the alarm relay immediately after an alarm is detected.
90 Phason
Programming the alarm and display settings
Another important setting is alarm silencing. Silencing temporarily disables an alarm setting after an alarm has been acknowledged. This prevents the alarm relay from activating immediately after acknowledging the alarm. If the alarm condition is still present after the silencing period, the alarm relay activates again.
You can set the silencing duration to be from 0 seconds to 30 minutes. If you set it to 0 seconds, acknowledging the alarm will not deactivate the relay; the alarm relay remains active until the alarm condition goes away.
Besides the standard high and low temperature alarms, the Supra has many other alarm conditions. For a complete list and descriptions, see the Alarm settings worksheet on page 142.
How alarm settings work
Let’s say the high temperature alarm setting is 85.0°F, the minimum duration is 5 minutes, and the
silencing duration is 15 minutes. If the temperature rises to 86 degrees, but drops below 85 degrees 2
minutes later (before the minimum duration of 5 minutes), the alarm relay does not activate.
If the temperature rises to 86 degrees and stays there for 5 minutes, the alarm relay activates. The alarm relay remains active until a user acknowledges the alarm or the temperature drops below the
high temperature alarm setting. After the alarm has been acknowledged, if the temperature remains
above the high temperature alarm setting, the relay activates again in 15 minutes (after the silencing
duration).
How alarm biasing works
The purpose of alarm biasing is to prevent the alarm from sounding on very hot days when the temperature set point cannot be maintained. The bias temperature is added to the high temperature
alarm setting if the outdoor temperature is higher than the high temperature alarm setting.
21040012 91

A bias temperature of 5°F allowed so that the room temperature can rise to 85°F before an alarm occurs.
The room temperature exceeds the normal alarm temperature. No alarm occurs because the room temperature is lower than the high temperature alarm plus the alarm bias.
