Overview
RS485 Thermostat
The TR65 thermostat provides typical thermostat control of a central heating and cooling HVAC system
plus has the added feature of RS485 communications for remote control. The TR65 is a two part
thermostat with a Wall Display Unit and a HVAC Control Unit.
The Wall Display Unit (WDU) has a large, backlit graphical display, control buttons, status LEDs and a
temperature sensor. The WDU can display multiple screens for different functions of the thermostat. In
the default thermostat control screen, shown below, it displays the current room temperature, heating and
cooling setpoints, system mode, manual fan mode, time, and status information.
Display operation
Thermostat control screen
Normally the thermostat displays the thermostat control screen as shown above. Using the “Menu”
button, you can access other screens and functions of the thermostat.
Minimized Display Mode
Optionally, you can set the thermostat to show only the temperature in a “minimized” display mode.
This mode can be set on or off in the thermostat “Us ers Settings” menu.
Backlight
The thermostat has a backlit display for low light and night visibility. It can be set to remain on constantly,
or to turn off after a 20-120 second delay. These are selectable in the User Settings menu.
Function Control Buttons
The thermostats buttons are “Soft Keys” meaning that they change functions when you change screens.
The function of the button is defined by “on-screen labels” that are dynamic and change when you change
screens

Setpoint Display
The current heating and cooling setpoints are displayed next to the Setpoint Up/Down buttons.
Thermostat Operation Buttons
Pressing these buttons will take you to the following screens:
Menu – go to the Main Menu Screen to select other thermostat
settings screens.
System Mode – go to the Sy stem Mode screen to set
thermostat operating mode.
Fan Mode – go to the Fan mode screen to set the fan mode.
Schedule Mode – go to the Schedule mode screen to set
schedule mode or setback.
Setpoint Up/Down Buttons
Press either the Up or Down buttons to go to the Heating or Cooling Setpoint screen.
NOTE: If the thermostat is in the OFF mode, pressing the setpoint Up/Down buttons will take you
to the System Mode Screen. You must first select an operating mode to be able to change the
setpoint for that mode.
Time Display
The current time is displayed in the upper left corner of the main screen. Set the clock from the User
Settings Menu. The time will blink when the clock has not been set.

Setting Heating or Cooling Setpoints
Setpoint Up and Down Buttons
Press either the Up or Down button in the main Thermostat Control Screen to go to the current system
operating mode (Heating or Cooling) Setpoint screen, as shown below.
Heating /Cooling Setpoint Adjustment Screen
The UP and DOWN buttons adjust the setpoint temperature. Pressing the UP button will increment the
setpoint value by one degree and conversely, pressing the Down button will decrement the setpoint one
degree. Pressing and holding a button will cause the setpoint to continuously change until the button is
released.
Setpoint Range: The setpoints can be set from 50F to 90F (4C to 32C) for heating or 55F to 99F
(10C to 37C) for cooling.
Setpoint Push: Note that you cannot lower the cooling setpoint below the heating setpoint. The
thermostat will “push” the heating setpoint lower if you try to lower the cooling setpoint below the heating
setpoint. It maintains a 4 degree separation between the heating and cooling setpoint. The same is true
for raising the heating setpoint above the cooling setpoint. Again the thermostat will “push” the cooling
setpoint up to maintain the 4 degree separation. (Setpoint delta is adjustable in the Installer Settings)
NOTE: If the system mode is OFF, pressing either the Up or Down buttons will take you to the
System Mode screen. You must first set an operating mode before you can change the setpoints.
To change the Heat Setpoint you must be in Heating mode, to change the Cool Setpoint you must
be in the Cooling mode. If you are in Auto mode, the mode of the last system call will be the
setpoint screen displayed.

Special Heat Pump Mode
EHEAT Mode: An additional system mode, “EHEAT” for Emergency Heat will be displayed if the
HVAC system type is set to Heat Pump. If there is a compressor failure with the Heat Pump system,
setting the mode to EHEAT will allow the stage 3 supplemental or aux heat (W1) to come on first
whenever there is a call for heating. It also disables the compressor outputs (Y1/Y2) to prevent
further damage to the HVAC system.
