Dump Valve TVT Control Vs 784519-1
INTRODUCTION
This brewer incorporates our latest TVT controller technology. At the heart of the system is a LCD display
with digital readout and icons indicating brewer functions. The end user need only set 3 brew criteria for each of
the 3 brew profiles. Simply tell the brewer how hot (Temperature), how much (Volume), and how long (brew
Time) for each brew profile. An additional programming mode allows control of additional features such as sentry
timer, visa-brew time, calibration for flow rate, and display of temperature and volume units. All set from the front
control panel using a digital display for precise control. The following pages will explain the control features and
the process required to program your unit.
Power Up Modes
Once the brewer has been connected to a water supply, you are ready to plug unit in. When plugging
brewer in it will go into one of three power up modes. These modes are; Factory Settings Access, Default
Settings Load, and Normal Mode. Normal mode will be discussed first.
Normal Power Up Mode – This is the mode used for setting up a new piece of equipment from the factory. This
mode will be automatically selected by plugging in the brewer without holding in any of the controllers buttons.
This brewer features a liquid level control board and tank probe to regulate the water level in the tank.
When the brewer is initially plugged in the liquid level board will check for water in the tank and will turn on the fill
valve if necessary to fill up the tank. The brewer will not heat until the fill cycle has been completed. Water will be
replenished when used for brewing or through faucet use.
Once the unit has been filled, it will enter its idle mode. The brewer is considered idle when it is powered
up but is not yet brewing and no settings are being adjusted. If the heater is on, the display will show the
thermometer icon. If the unit is at least 1 degree away from set point temperature the happy face icon will turn on
and the thermometer will pulse in synchrony with the heater as it maintains proper temperature. If the tank
temperature is above set point, both the thermometer icon and tank heater will remain off. See “User Program
Mode” to set brew profile information.
Access to Factory Settings – This mode allows control of additional features such as sentry timer, visa-brew time,
calibration for flow rates, and display of temperature and volume units. This mode may be selected by holding
center button for 2 seconds when first plugging unit in. The current software revision will scroll across the screen
and “Pro” will then briefly display to indicate you are in program mode. Increment values up and down using right
and left buttons when appropriate parameter is displayed. The following are the parameters that may be set in
this mode and the icon that displays for each.
a) En2 – This is an option for future use. It currently has no effect. Leave set on En2.
b) Temperature Display - (Thermometer icon flashes) Temperature may be displayed using either
ºF or ºC. Selected unit is shown in main display area as well as to the right in a smaller font.
c) Volume Display - (Pot icon flashes) Volume may be displayed using either units of ounces or
liters, Oz or L. Selected unit is shown in main display area as well as to the right in a smaller font.
Liters will be displayed in increments of .05. (.05L = 1.69oz).
d) Sentry Timer – (Pot & Clock icons flash) Will countdown after each brew (0:30min – 19:59 hours)
After any brew, the sentry timer will activate & the CLOCK icon will turn on. The CLOCK icon will
flash when the sentry timer expires to indicate the brewed beverage is no longer “fresh” (unless a
new brew is started before the timer is allowed to expire).
