TS16 Wall Display Unit
The TS16 Wall Display Unit has a LCD display and control buttons for changing the setpoint, system
operating mode and manual fan mode. The WDU also has an internal temperature sensor. The display
serves as a common display for many functions. It normally shows the current room temperature but
switches to show setpoint, mode or other functions when buttons are pushed. Two on-screen indicators
show the state of the manual fan and setback mode.
Any changes, such as the temperature or control button operations at the WDU are sent to the HVAC
Control Unit. In turn, the Control unit can send changes in setpoint or modes up to the WDU. When
updates are received, they are displayed on the LCD for 3 seconds and then the display returns to the
current room temperature.
LCD Display
The LCD display is a two digit multifunction display that normally shows the current room temperature. It
has a continuous backlight for easy viewing anytime. Whenever any of the control buttons are pushed, the
LCD display will change to show that function’s current status. The LCD display will stay in the new display
mode as long as buttons are being pushed. After 3 seconds of no activity, the display will change back to
show current temperature.
The right decimal point on the LCD display will turn on whenever manual fan is ON. The left decimal point
will flash whenever the setback mode is ON.
Remote changes in setpoint or modes that are received from the Control Unit will cause the LCD display to
switch and display the updated data for 3 seconds and then return to current temperature.
Control Buttons
The
UP
and
DOWN
buttons control the setpoint temperature. Pushing the
UP
or
DOWN
button
once
will
cause the LCD display to change to
show
the current setpoint temperature (but won’t change it). Pushing
the button again, before the display switches back to current room temperature, will decrement or
increment the setpoint value by one degree. Pushing and holding a button down will cause the setpoint to
continuously ramp up/down until the button is released. After 3 seconds of no activity, the LCD display will
change back to show the current room temperature and the new setpoint value will be sent to the Control
Unit.
The max cooling setpoint is 110 deg F (43 deg C). The max heating setpoint is 106 (41 deg C).
Min setpoint is 40 deg F (5 deg C) for heating and 44 deg F (7deg C) for cooling.
