Specifications Overview • 1
1Overview
The Emerson Programmable Touchscreen Thermostat (P/N 810-1600) is a 
configurable device intended for light commercial applications. The thermostat is a
communicating, intelligent sensor and controller combination with built-in 
temperature and humidity sensors used to control systems such as conventional
Rooftop Units (RTU) and Heat Pumps (HP). The thermostat communicates over a
Modbus RTU network that easily integrates with a building management system
(BMS).

2 Installation
2.1. Enclosure
2.2. Thermostat Location
The thermostat should be mounted:
> About 5 ft (1.5 m) from the floor.
> On a part of wall without hidden pipes or ductwork.
> In a room that operating limits are within 32°F to 122°F (0°C to 50°C).
> In a room that humidity operating range is within 0% to 95% relative humidity, 
non-condensing.
The thermostat should not be mounted:
> Nearby a window, on an outside wall, or next to a door leading to the outside.
> Where exposed to direct light and heat from any heat source, such as a lamp, the sun,
a fireplace, or any heating element which may cause a false reading (temperature 
measurement offset).
> Nearby a direct airflow from supply registers (air vent or duct outlet).
> In areas and locations with poor air circulation such as behind a door.

2.3. Thermostat Installation
2.3.1. Opening and Closing the Thermostat Enclosure
To open the thermostat enclosure, grip the top and the bottom edge of the front part
of the device and pull straight. A certain physical resistance is normal from the 
24x contacts pins (terminal strips and terminal blocks) that have to be separated
during the operation.
To close the thermostat enclosure, make sure to align the top and the bottom tabs 
between the front part and the baseplate, and then push the front part firmly toward
the wall. Again, some force is required to mate both parts.
2.3.2. Mounting the Baseplate on the Wall
Figure 2-2 - Exploded View of Thermostat
NOTE: Both top and bottom securing screws are optional and normally not installed on the
units.
Figure 2-3 - Baseplate (Back view)

Thermostat Installation Installation • 5
To fix the baseplate on a wall, pass the wires through the opening of the baseplate,
and use either 2x self-taping screws and dry-wall anchors, or regular 6-32 machine
screws to attach on a standard single-gang electrical junction box (2” x 4”).
2.3.3. Wires and Electrical Connection
Once the baseplate is affixed on the wall, proceed with the wiring connections to the
terminal block. Please refer to Section 2.4., Wiring and Connections for 
configuration and signals definition.
CAUTION! Do not over-tighten the screws when attaching the baseplate on a wall as
physical damage may occur.
CAUTION! Keep the thermostat housing and vents clean and free of any debris to avoid
malfunction of the device.

Graphical User Interface (GUI) Operation • 9
3Operation
3.1. Graphical User Interface (GUI)
The display of the device is used as the Graphical User Interface to show some of
the status, setpoints and actual measurements such as room temperature and relative
humidity. The display is a resistive touch-type that allows users to navigate and to
change values that are shown on the display (see Figure 3-1).
3.2. Configuration Menu
To access the Configuration Menu (see Figure 3-2), press the icon for five (5)
times within 15 seconds. This step is to prevent unintentional access to the 
configuration menus.

3.2.1. Configuration Menu — Modbus Device Address
The first configuration menu (see Figure 3-3) allows users to change the Modbus
device address. Ad is shown on the right side of the display to indicate which 
parameter is being changed (Ad stands for Address). To change the value, press 
either the up or down arrow, and then press the check icon to go to the next 
parameter. Press CA to cancel and exit the configuration menu without saving any
changes.

3.2.2. Configuration Menu — Modbus Device Baud Rate
The second configuration menu (see Figure 3-4) allows users to change the Modbus
device baud rate. “br” is shown on the right side of the display to indicate which 
parameter is being changed (br stands for Baud Rate). To change the value, press 
either the up or down arrow, and then press the check icon to go to the next 
parameter. Press CA to cancel and exit the configuration menu without saving any
changes.

3.2.3. Configuration Menu — Thermostat System Configuration
The third configuration menu (see Figure 3-6) allows users to set the thermostat 
system configuration. SC is shown on the right side of the display to indicate which
parameter is being changed (SC stands for System Configuration). The current 
revision of the Emerson Programmable Touchscreen Thermostat supports 
Conventional HVAC Systems such as RTU and Heat-pump Systems using a 
reversing valve. There are 4x possible configurations: IDLE, RTU, HP_O and 
finally HP_B. The first system configuration is IDLE. In this configuration, all the
outputs of the thermostats are open and the thermostat controls are inactive. This is
to prevent any issue in current configuration compared to the equipment connected

to the thermostat. To change the value, press either the up or down arrow, and then
press the check icon to go to the next parameter. Press CA to cancel and return to the
normal display without saving any changes.

(1, 2, or 3) Current Configuration
• When the system is not in nominal configuration, for example, configured in IDLE,
then all the configurations are accessible through the menu as below:
• When the system is already configured in RTU, HP_O or HP_B, only the IDLE and the
current configuration are accessible through the menu:
NOTE: The thermostat is always as a 2H/2C configuration system for both RTU and Heat
Pump. In the case the system has only 1 stage (1H/1C), this configuration is inclusive within
the 2-stages configuration. In this case, connect stage 1 terminals (Y1 and W1) and leave
stage 2 terminals floating.
Menu Option Number System Configuration

*NOTE: O and B signals are both reversing valve control signals, but are logically
complementary (opposite).

Table 3-4 - Thermostat System Configuration
IMPORTANT! Prior to any change of system configuration, the unit must be set to IDLE
configuration first, and then to the final desired configuration.

Configuration Menu Operation • 13
IMPORTANT! A factory reset of all parameters will occur when the system is in IDLE
configuration, except the current date and time that are kept with the use of a Real-Time
Clock (RTC). This factory reset will be triggered on the first start of the device, and when
newly configured from RTU, HP_O or HP_B to IDLE configuration.
IMPORTANT! Upon the first start of the thermostat, the default System Configuration will
be set to IDLE. This means that the first step to get the device started is to configure the
appropriate system configuration. This menu will appear by default upon the first start (See
Figure 3-5). To access the configuration menu, press the icon for five (5) times
within 15 seconds.

Configuration Change)

IMPORTANT! Device restart time is about 5 to 10 seconds. Prior to device restart, the
display will show “- -” to indicate that the device is not in trouble and that the booting
sequence is underway. (See Figure 3-7). When the device is rebooting, the display will turn
off for few seconds until reboot operation is completed.
Figure 3-7 - Thermostat Display When Restarting to Occur (Rebooting)
Figure 3-8 - Thermostat System Configuration Menu (New System Configuration Mode after IDLE)
IMPORTANT! To change the current system configuration to a different one, the operating
system requires the system configuration is set to IDLE prior to the final configuration each
time. This mechanism is to prevent any undesired operation on such an important setting.

Configuration Menu Operation • 15
3.2.4. Configuration Menu — Full Segments Display Test
The fourth configuration menu (see Figure 3-9) allows users to test the full 
segments display. This allows a complete review of the display segments and to 
inform the user of all possible segments in the current Emerson Programmable
Touchscreen Thermostat revision. Press the check icon to go to the next parameter.
3.2.5. Configuration Menu — System Revision Display
The fifth and last configuration menu (see Figure 3-10) allows users to obtain the
current system revision number. This number is shown with 3 digits. Note that there
is no decimal after the first digit, but the revision number contains the decimal point.
For example, revision number 100 shown on the display means in fact 1.00. The
software revision will be updated for the latest official release, and will likely be
higher than 1.00. Press the check icon to terminate the configuration menus. Press
CA to cancel any previous change and return to the normal display without saving.
