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). For more information, download the full user manual (P/N 026-1739) here: https://climate.emerson.com/documents/026-1739-emerson-programmable-touchscreenthermostat-installation-operation-manual-en-5390496.pdf
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 contact 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.
Note that both top and bottom securing screws are optional and normally not installed on the units.
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”).
CAUTION! Do not over-tighten the screws when attaching the baseplate on a wall as physical damage may occur.
Keep the thermostat housing and vents clean and free of any debris to avoid malfunction of the device
The thermostat should be mounted:

On the first start-up of the thermostat, the default System Configuration is idle. This means that the first step to get the device started is to configure the appropriate system configuration. The following menu will appear by default upon the first startup:
To access the Configuration Menu press the technician
Address Number | Modbus Device Address |
1 to 247 | Range from 1 to 247 |
Menu Option Number | Corresponding Baud Rate |
0 | 9600 bps |
1 | 19200 bps (default) |
Thermostat System Configuration
The third configuration menu 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 issues within the 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.
NOTE: By default, the thermostat is configured as 2 heat-stages and 2 cool-stages thermostats. The number of heating/cooling stages can be changed in the subsequent menus.
Menu Option Number | Corresponding Baud Rate |
0 | IDLE |
1 | RTU (Conventional Systems) |
2 | *HP_O (Heat-pump with O as reversing signal) |
3 | *HP_B (Heat-pump with B as reversing signal) |
Menu Option Number | Corresponding Baud Rate |
0 | IDLE |
(1, 2, or 3) | Current Configuration |
IMPORTANT! In order to change the thermostat’s configuration from a functional configuration (not IDLE) to another one, the thermostat must be set to IDLE configuration first, then all configuration options will be displayed on the screen and the new desired configuration can be chosen.
IMPORTANT! A factory reset of all parameters will occur when the system is set to the IDLE configuration, except the current date and time that are kept with the use of a Real-Time Clock (RTC).
Number of Heating Stages
For all systems, the number of heating stages can be modified inside this menu. On the screen, the letters “HS” stands for Heating Stages. Possible values are 1 heating stage, 2 heating stages. Press the Done icon to move on to the next menu. Values will not be saved until the last configuration menu is reached.
Number of Cooling Stages
For all systems, the number of cooling stages can be modified inside this menu. On the screen, the letter “CS” stands for Cooling Stages. Possible values are 1 cooling stage, 2 cooling stages. Press the Done icon to move on to the next menu.
Values will not be saved until the last configuration menu is reached.
Full Segments Display Test
The fourth configuration menu allows users to test the full display segments. 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.
The fifth and last configuration menu provides the current system revision number. This number is shown with three digits. Note that there is no decimal after the first digit, but the revision number contains a decimal. For example, revision number 100 on the display = 1.00. The software revision will be updated for the latest official release, and will likely be higher than 1.00. Touch the letters “CA” to cancel any previous changes and go back to the normal display without saving. Press the check icon to terminate the configuration menus.
IMPORTANT! If at least one of those parameters has been changed, the thermostat will reboot: Thermostat system configuration, number of Heating stages or number of Cooling stages.
Prior to device restart, the display will show “- -” to indicate that the device is about to reboot. When the device is rebooting, the display will turn off for approximately a few seconds until reboot operation has been completed.
