SETUP
The setup parameters are common to all programs and can only have one setting. They can not be
accessed by the same procedure as the normal parameters. This has been done to protect these parameters
from accidentally being changed. Follow the instructions on page 11 to reprogram these parameters.
17 TEMPERATURE UNITS [
o
F -
o
C] - This parameter programs the TVS to display the temperature in
Fahrenheit or Celsius.
18 STAGE 3 OPERATION [HEAT - COOL] - This parameter programs the Stage 3 output to operate
as a heating stage or a cooling stage. When it is set to HEAT, the stage will be on below the Stage 3
Turn On (parameter #9). If it is set to COOL, the stage will be on above the Stage 3 Turn On (#9).
19 Not Applicable
20 Not Applicable
21 STAGE 1 MINIMUM IDLE [0 - 99] - This is the minimum idle preset in percent of full speed. The
Stage 1 Min Vent (#2) cannot be adjusted below this setting. If it is programmed to 20 the Stage 1
Min Vent (#2) parameter cannot be adjusted below 20. It is recommended that this parameter be
programmed to correspond to the lowest speed at which the motor can safely operate.
22 STAGE 2 MINIMUM IDLE [0 - 99] - This is the minimum idle preset in percent of full speed. The
Stage 2 Min Vent (#3) cannot be adjusted below this setting. If it is programmed to 20 the Stage 2
Min Vent (#3) parameter cannot be adjusted below 20. It is recommended that this parameter be
programmed to correspond to the lowest speed at which the motor can safely operate.
23 HYSTERESIS [0.5 - 2.5
o
F, 0.3 - 1.4
o
C] - This is the number of degrees of difference between the
turn-on point and turn-off point for all stages. It is the number of degrees above the turn-on point that
a heating stage will turn off, and the number of degrees below the turn-on point that a cooling stage
will turn off.
24 STAGE 1 POWER FACTOR COMPENSATION [0.5 - 2.5] - This is set at the factory to 1.0 and
should only be adjusted if the Stage 1 variable speed fan does not operate properly with the TVS.
25 STAGE 2 POWER FACTOR COMPENSATION [0.5 - 2.5] - This is set at the factory to 1.0 and
should only be adjusted if the Stage 2 variable speed fan does not operate properly with the TVS.
