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:
1) Main: Main parameters control the main operation of the control.
2) 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.
3) General: General parameters are common to all programs. These
parameters can have only one setting which is the same in all
programs.
4) Setup: Setup parameters control the overall operation of the unit.
These parameters can have only one setting which is the same in all
programs.

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.

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 ld button.

TVS operation
Figure 2 shows the operation of each stage of the TVS. This particular diagram shows the temperatures at
which the stages would turn on and off if the TVS was operating according to the factory settings in
program A. Some settings are listed here but the entire factory program table can be found on page 20.
The circled numbers in the diagram correspond to the parameter numbers. Use these numbers to cross
reference the parameters in the diagram to their descriptions. All stages except the low temperature and
high temperature alarms have a programmable hysteresis, parameter # 23.

12 Low Temp Alarm -3.0
13 High Temp Alarm 10.0
NOTE: When the variable speed stages turn on, they will run full speed for three seconds and then
decrease to the required speed.
EXAMPLE
As an example, say the temperature is 75oF and rising. At this point the Low Temp Alarm will be on.
When the temperature rises to 82oF, the Low Temp Alarm will turn off and the Stage 1 fan will turn on.
The Stage 1 fan will run at full speed for three seconds and then slow down to the Minimum Ventilation
setting.
At 85oF the Stage 1 P-Band begins. While the temperature rises in the P-Band, the Stage 1 fan will
increase in speed. At 87oF Stage 1 will be at full speed.
When the temperature rises to 88oF the Stage 2 P-Band begins. Since the Stage 2 fan has been off until
now, it will run full speed for three seconds and then slow down to the required speed. As the temperature
rises, the Stage 2 fan will increase in speed proportionally to the temperature. At 90oF the Stage 2 fan will
be at full speed.
At 90oF Stage 3 (cool) will turn on.
When the temperature rises to 95oF the High Temp Alarm will turn on.
