Programmable Touchscreen Thermostat  

Setup in E2 and Site Supervisor  

Quick Start Guide  

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:

Thermostat Installation and Mounting  

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.  

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:  

> 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.

EMERSON Programmable Touchscreen Thermostat Setup in E2 and Site Supervisor User Guide Overview

Summary of Contents

• Page 1: Programmable Touchscreen Thermostat 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. The thermostat communicates over a Modbus RTU network that easily integrates with a building management system. To open the thermostat enclosure, grip the top and bottom edge of the front part of the device and pull straight. To close the thermostat enclosure, align the top and bottom tabs between the front part and the baseplate, then push the front part firmly toward the wall. To fix the baseplate on a wall, pass the wires through the opening of the baseplate and use either self-taping screws or regular machine screws. Do not over-tighten the screws when attaching the baseplate on a wall as physical damage may occur. The thermostat should be mounted about 5 ft from the floor and in a room with operating limits within 32°F to 122°F. The thermostat should not be mounted nearby a window, on an outside wall, or next to a door leading to the outside. Keep the thermostat housing and vents clean and free of any debris to avoid malfunction of the device.
• Page 2: Thermostat wiring and connections involve connecting the terminal block after affixing the baseplate on the wall. The thermostat power and communication matrix outlines connections for various systems, including 2H/2C systems and heat pump systems. For systems with only one stage, the second stage terminals can be left floating open. On the first start-up, the default system configuration is idle, requiring configuration for operation. To access the configuration menu, press the technician icon for 10 seconds. If previously configured, the technician icon must be displayed by touching the right-bottom corner of the screen. The document includes a part number and revision information. The content is intended for personal use and may be photocopied. For the latest technical documentation and updates, a website is referenced.
• Page 3: Configuration menu access allows users to change the Modbus device address. The first configuration menu shows Ad on the display to indicate the address parameter being changed. To change the value, press the up or down arrow and then the check icon to proceed. Press CA to cancel and exit the configuration menu without saving changes. The Modbus device address range is from 1 to 247. The second configuration menu allows users to change the Modbus device baud rate. “br” is displayed to indicate the baud rate parameter being changed. To change the baud rate value, use the up or down arrow and then the check icon to proceed. Press CA to cancel and exit the baud rate configuration menu without saving changes. Document part number is 026-4850 Rev 1.
• Page 4: Thermostat system configuration allows users to set the thermostat 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 four possible configurations: IDLE, RTU, HP_O, and HP_B. In the IDLE configuration, all outputs of the thermostats are open and the thermostat controls are inactive. 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. By default, the thermostat is configured as a 2 heat-stages and 2 cool-stages thermostat. The number of heating/cooling stages can be changed in the subsequent menus. When the system is not configured, all other configurations are accessible through the menu. Configuration menu options include IDLE, RTU, HP_O, and HP_B.
• Page 5: 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. In order to change the thermostat’s configuration from a functional configuration to another one, the thermostat must be set to IDLE configuration first. A factory reset of all parameters will occur when the system is set to the IDLE configuration, except current date and time that are kept with the use of a Real-Time Clock (RTC). The number of heating stages can be modified inside this menu. The letters “HS” stands for Heating Stages. Possible values for heating stages are 1 heating stage, 2 heating stages. The number of cooling stages can be modified inside this menu. The letters “CS” stands for Cooling Stages. Possible values for cooling stages are 1 cooling stage, 2 cooling stages. Values will not be saved until the last configuration menu is reached.
• Page 6: Thermostat display when restarting occurs (rebooting) System configuration menu (new system configuration mode after idle) 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. System revision display 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. The software revision will be updated for the latest official release.
• Page 7: System revision display If at least one of those parameters has been changed, the thermostat will reboot. Prior to device restart, the display will show “- -” to indicate that the device is about to reboot. The programmable touchscreen thermostat requires adding a description file to E2.
