Definition of terms

NORMAL OPERATION The TVS is in normal operation when it is displaying room temperature.

When alarms occur, the display will alternately flash the alarm signal and room temperature.

PROGRAMS Programs consist of the Main, Differential, General and Setup parameters.

The TVS has seven programs that can be selected and reprogrammed by the user.

OPERATING PROGRAM The TVS operates according to the parameters in the operating program. Any

one of the seven programs may be selected as the operating program.

PARAMETER LIST The parameter list is shown on page 19, and is printed on the front of the

TVS control. It is a list of all the parameters that may be programmed by the user.

PARAMETERS Parameters are the individual settings that may be programmed. Read the

PARAMETER DESCRIPTIONS section on page 16 for an explanation of each parameter. There are four categories of parameters:

Main: Main parameters control the main operation of the control.

Differential: These parameters are programmable differentials. They are the number of degrees above or below the temperature set point the particular stage starts or turns on.

General: General parameters are common to all programs. These parameters can have only one setting which is the same in all programs.

Setup: Setup parameters control the overall operation of the unit. These parameters can have only one setting which is the same in all programs.

Adjusting the TVS

Selecting a new operating program

As livestock mature, often the room climate needs to be changed. The TVS has seven different programs in memory for seven different climate settings. Any one of these programs can be the operating program. In order to change the operating program of the TVS, follow the instructions below. For a list of the factory settings see Table 2 on page 20.

1) Press the PROG button once.

The TVS will display the current operating program (one of A, b, C, d, E, F or g). The display will flash the program name and Pr.

2) Press the PROG button several times until the desired

program is displayed.

By pressing the PROG button, the program names are displayed one after another. To change to a different operating program, press the PROG button until the proper program is displayed.

3) Press the STORE button to enter the desired program

into memory.

When the correct program is displayed, pressing the STORE button will tell the TVS to use the selected program as the operating program. After Stor is displayed, the TVS returns to normal operation.

Changing parameter settings

Follow the steps below to view and/or edit the parameters in any program. After editing the parameters, mark the changes in the Blank Program Tables in Appendix D for future reference.

1) Press the PROG button until the program that you want to

edit is displayed.

The display will flash the program letter (A to g) and Pr.

2) Press the PARM button once.

The first (left-most) digit shows the program letter that is being edited.

The second digit indicates if the program is the operating program. An o means the program is the operating program, a blank means it is not the operating program.

The two right-most digits show the parameter number to be edited.

3) Press the UP or DOWN key to turn memory protect off.

The display will show Ao 0 and then oFF, indicating memory protect has been turned off. The parameters can now be adjusted. If memory protect is not turned off, the parameters can only be viewed. Attempting to adjust the parameters while memory protect is on will result in an Err message being displayed.

10245506 9

TVS user manual Phason

4) Press the PARM button to step through the parameter list

until the desired parameter is reached. Refer to the front cover of the TVS control or see Table 2 on page 20 for the parameter list.

5) Use the UP / DOWN buttons to adjust the setting.

The parameter can be adjusted to any value with in the

parameter's range. The ranges can be found on page 19.

6) Press STORE to save the setting in memory.

The display will show Stor for 1 second indicating the new setting has been stored in memory. If the PARM button is pressed before pressing STORE the next parameter will appear and the previous one will change back to its previous

setting.

Continue through the parameter list by pressing the PARM button and making changes to the settings where needed. Follow the same procedure shown in steps 4 to 6 above.

7) To return to normal operation (displaying of room

temperature) at any time, press the RETURN button.

When RETURN is pressed, memory protect is automatically turned back on. If a parameter has been changed but the value has not been stored, pressing RETURN will change the parameter's setting to the last stored setting and return the control to normal operation.

NOTE: If the TVS is left displaying a parameter it will revert back to normal operation in 1 minute automatically. If STORE was not pressed the displayed parameter will change back to its previous value.

Phason TVS user manual

Setup parameters

The setup parameters should be programmed when the installation has been completed to configure the TVS, and then generally the parameters do not need to be reprogrammed. These parameters are different from the other parameters because they do not have a different setting for each program and cannot be edited in the normal way. Each setup parameter setting is common to all programs. Follow the instructions below to change the setup parameters.

When the setup parameters have been programmed, the blank program table in Appendix D should be filled in with the new settings for future reference.

To edit the setup parameters

Press the PARM button once to enter the edit mode. If you wish to edit the setup parameters, you must turn off the memory protect now. See page 9 to turn off the memory protection.

Next, press the PROG and PARM buttons simultaneously to get to the setup parameters. The Setup parameters can be adjusted as needed and stored in the same way the normal parameters can. After the setup parameters have been changed and stored, press the RETURN button to return to normal operation.

Programming tips

Scrolling backwards

When viewing or editing the parameters, sometimes it is helpful to scroll backwards through the parameter list. To do this, press the PARM and UP buttons simultaneously. Instead of the TVS displaying the next parameter on the list, it will display the previous parameter.

10245506 11

TVS user manual Phason

Selecting a parameter to edit

The parameters are stored in a table in memory that is similar to the Factory Program Table on page 20. Any parameter in any program can be edited when memory protection has been turned off. Follow these procedures when editing parameters to become more efficient.

To move down to the next parameter press the PARM button.

To move up or backwards to the previous parameter, press the PARM and UP buttons simultaneously.

To move right, press the PROG button until the desired program is displayed, then press the PARM button once to edit the same parameter number that was being edited before.

To Move Button(s)

 PARM  PARM and UP  PROG

An example of where this method of programming is useful is a situation where the temperature set point of each program needs to be changed. This can done by turning off memory protection and changing the temperature set point in the operating program (the operating program is displayed with an o and the program name). Then press the PROG button twice to edit the next program. Press the PARM button and edit the parameter. To continue to the next program press the PROG button twice again. Remember that STORE must be pressed after each change to save the new setting in memory.

Fast editing

When editing the setting of a parameter by adjusting it up or down, hold down either button and then press the other one. This will change the setting ten times faster. If you want to increase the setting, hold down the UP button and then press the DOWN button. The setting will increase ten times faster. To decrease the setting ten times faster, ho down the DOWN button and then press the UP

button.

GENERAL PARAMETERS

General parameters have one setting common to all programs. When they are changed in one program, they change in all programs.

14 LOW POWER ALARM [ON - OFF] - When the line voltage drops below the proper operating level

a low power alarm will be displayed (A LP). This alarm may be disabled by adjusting it to OFF. When disabled, the display will still flash A LP but the alarm relay will not activate.

15 LATCHING ALARMS [ON - OFF] - When this parameter is turned ON, all alarms will be

displayed on the TVS and will continue to flash after the alarm condition is gone. They can be reset by pressing the RETURN button. This feature is useful to keep track of the alarms that occur during times when the control is not being supervised. For example; in the morning, the TVS could be checked for alarms that occurred during the night and then the alarms could be cleared. If this parameter is turned OFF, the display will only show the alarm when the condition is present. When the alarm condition is gone, the alarm will no longer be displayed.

16 VENTILATION [ON - OFF] - When this parameter is turned OFF, the variable speed outputs and

cooling stages are turned off completely and all alarms will not be displayed. The heating stages are not affected. Ventilation may be turned OFF when a room is vacant to conserve energy. When it is turned OFF the TVS will display VoFF. DO NOT use this to shut down fans to work on the wiring ensure the breakers are turned off.

22 2009-09-15

appear for 2 seconds and then disappear. The high temperature alarm appears when the room temperature is above the high

temperature alarm setting (parameter #13). Check if the fans are operating properly. This alarm may occur on very hot days when the desired room temperature can not be maintained.

The low temperature alarm appears when the room temperature is below the low temperature alarm setting (parameter #12). Check if the heater is operating properly.

Phason TVS user manual

The low power alarm turns on when the line voltage drops below 190 for 230 VAC operation or below 95 for 120 VAC operation. This indicates a problem with the electrical service of the building. The control may operate erratically if the voltage drops below these levels.

This indicates the temperature sensor is disconnected. The sensor wire may be broken or damaged somewhere.

This alarm indicates the temperature sensor is short circuited. The sensor or wire may be damaged somewhere.

NOTE: When a A Pd or a A PS alarm occurs, the heating and cooling stages will turn off

and the variable stages will run at idle speed.

The Power Failure alarm appears when there has been an interruption in the power. The control will continue to operate normally and the alarm can be cleared by pressing the RETURN button.

When this alarm appears it indicates an internal error has occurred. To clear this alarm check through the parameters; adjust and store the ones that are incorrect. Next, turn the power off and then back on and the alarm will be cleared.

NOTE: A parameter must be changed and stored and the power turned off and on before

the alarm will be cleared. Another way to clear the alarm is downloading the factory programs. This will reset all the parameters to the factory settings and then they must be programmed to the desired settings again. Consult your dealer or Phason for information to prevent this problem from happening again.

VoFF is displayed when VENTILATION (parameter #16), is turned OFF. When this is displayed, the variable speed stages and the cooling stages will be turned off. The heating stage(s) will operate normally.

Care and maintenance

Moisture will not cause a problem with the control if the proper care is taken in installation. The control's enclosure is made of fire retardant plastic and is sealed with a rubber gasket. The sensor entry is sealed with a liquid tight cable connector.

Caution should be taken when washing the room with a high pressure washer. DO NOT direct a high pressure washer at the control. In order to clean the control, wipe it with a damp cloth.

Be sure power is off before cleaning to avoid electrical shock.

MAINTENANCE

1) To prevent damage to the control, after the first two weeks of operation remove the cover from the

unit and check for moisture inside. Be sure to turn off the power to the control before opening the cover.

2) If moisture is present, wipe it out with a dry cloth and check the cable entry points and rubber gasket

for proper sealing.

3) If the cable connectors are not sealing, apply RTV or Silicon II sealant around the cable.

WARNING: If a sealant is used, be aware that some silicone sealants release acetic acid while curing. This can cause corrosion damage to the control. Let silicone cure completely (1 to 3 days), before closing the control or the control may be damaged and the warranty will be VOID.

4) Check the control again after two weeks to verify that it is properly sealed.

The control should be opened and inspected once a year for moisture. Proper care and maintenance will extend the life of the control.

Power factor correction

Adjusting the P-Band to correct for a particular power factor may improve your ventilation system's performance. Power factor correction is generally unnecessary and there is no danger of damage being done to the control or motor if it is not done. As a result of different power factors between the many makes and models of fan motors, the actual P-Band may be less then the P-Band setting displayed by the control.

If the power factor of the motor is available, use the chart of correction numbers (listed in table 4 below) and CALC 1 below to calculate the P-Band setting required in order to get the desired P-Band. A power factor of 0.8 or greater will cause an insignificant change to the P-Band and does not need to be corrected.

POWER

FACTOR

1.0 1.00

0.9 1.05

0.8 1.10

0.7 1.25

0.6 1.33

0.5 1.60

Table 4: Power Factor Correction Numbers

CALC 1: P-BAND SETTING = DESIRED P-BAND x CORRECTION NUMBER

Example 1: To have a 6oF P-Band with a motor which has a power factor of 0.7, set the P-Band to 7.5oF

(ie. 6

F x 1.25 = 7.5oF).

CORRECTION

NUMBERS

10245506 25

TVS user manual Phason

If the power factor is not known the correction number may be measured. Follow the steps below.

1) Set the Minimum Ventilation parameters (# 2 and 3) to the desired value.

2) Set the P-Band(s) to 10

F (parameters # 5 and 8).

3) Observe the ROOM TEMPERATURE.

4) Adjust the TEMP SET (parameter # 1) to equal the ROOM TEMPERATURE and Stage 2 Start PBand2 (parameter # 7) to 0. The Stage 1 and Stage 2 fans will now be running just above minimum ventilation.

5) Slowly decrease the TEMP SET (parameter # 1) and listen to the fans increase in speed.

6) Observe the TEMP SET (FULL SPEED TEMP SET) at which the motors reach full speed.

7) Use CALC 2 to calculate the Correction number for the motors as follows:

CALC 2:

10oF = Correction number FULL SPEED TEMP SET - ROOM TEMPERATURE

Example 2: ROOM TEMP = 75

F and FULL SPEED TEMP SET = 82oF

Correction Number =

10oF = 1.43

F - 75oF

Now use CALC 1 to find the P-Band setting.

General warnings

BE SURE POWER IS OFF BEFORE DOING ANY WIRING. The TVS should be installed by a qualified electrician. Install all equipment according to the applicable local electrical codes.

Most variable speed fan motors draw more current at fractional speeds than at full speed. Fan motor specifications show current draw at full speed. The increase in current draw may be as much as two times the rated current. Current over 7.5 Amps will cause overheating and eventual failure of the TVS. Please check current requirements for the fan motor by either measuring current draw at all speeds from idle to full speed or consult the dealer for information on the particular fan.

CAUTION: Stages 1 and 2 are for control of shaded pole, permanent split capacitor or universal

motors only.

ATTENTION: Destine uniquement a la commande de moteurs universels, a bague de dephasage ou a

condensateur permanent.

DO NOT mount power contactors inside the TVS enclosure. Power contactors create electrical noise, which may cause the TVS to work improperly.

Warning: Phason controls are designed and manufactured to provide reliable performance, but they are not guaranteed to be 100% free of defects. Even reliable products may experience occasional failures, and this possibility should be recognized by the user. If Phason products are used in a life support ventilation system where failure could result in loss or injury, the user should provide adequate back-up ventilation, supplementary natural ventilation or an independent failure alarm system. The user's lack of such precautions acknowledges their willingness to accept the risk of such loss or injury.

Electrical noise varies according to the type of equipment installed, the wiring layout and many other factors. It's effects are not apparent in most installations but over time it can cause degradation of electronic circuits, relays and power contactors. These transients can cause unreliable operation of your equipment if they are not properly controlled. A false 'A PF' alarm is due to electrical noise caused by high voltage transients in certain installations. Therefore, snubbing filters must be installed on all inductive loads for installations of this type. The filters must be connected in parallel with the load so the snubbing filter may absorb

Mounting instructions

To mount the TVS, remove the four screws in the front cover and lift off the cover. The cover can be unplugged from the bottom to make wiring easier. Mount the box to the wall with the four wood screws provided with the control. Insert the screws into the large holes in each corner of the box and tighten.

Use the knockouts provided at the bottom of the enclosure for mounting cable connectors. DO NOT make additional holes in the enclosure - this will void the warranty! All wires should enter the enclosure through the electrical-knockout holes provided and all grounds should be connected to the ground plate. When installing a control route the wires inside away from the control's electronics so that they are not draped across the components. This may result in a part being broken or damaged, which will affect the reliability of your control.

DO NOT mount the bottom enclosure with the electrical-knockouts located at the top of the enclosure. This may cause moisture to enter the control along the wiring and corrode the electronic circuitry, which voids the warranty.

Grounding and sealing

A - Connect all ground wires to ground studs. B - Use 3/4" liquid tight wire connectors for large holes. C - Use 1/2" liquid tight wire connectors for small holes. D - Use RTV silicone or Silicon II sealant to seal cable

entry points if liquid tight wire connectors are not used.

If silicone is used, be aware that some silicone sealants release acetic acid while curing. This can cause corrosion damage to the control. Let the silicone cure completely (1 to 3 days) before closing the control or the control may be damaged and the warranty VOID.
