TEMPTRAC INTERFACE GUIDE, GATEWAY SETUP AND POINTS LIST
OVERVIEW OF INTERFACE METHODS:
This document is a quick reference for connecting the TempTrac water heater / boiler control to a Building
Automation System (BAS). Direct connection via MODBUS RTU or using a gateway to interface to protocols other than MODBUS RTU are the methods covered in this manual.
BAS to Heaters direct, using MODBUS RTU:
BAS
PVI WATER HEATERS
Other equipment
Building Automation System (BAS) connecting directly to water heaters using MODBUS RTU twisted pair wire. (Wiring is RS-485 physical layer.)
BAS to heaters using a Protocol Gateway:
BAS
PVI WATER HEATERS
GATEWAY
Other equipment
Building Automation System (BAS) connecting to a PVI gateway. This can provide interface to BACNET
MSTP, BACNET IP, LONWORKS, and MODBUS TCP.
(Wiring from gateway to heaters is RS-485 physical layer. Wiring from BAS to gateway will depend on
Protocol.)
BAS to heaters using discrete connections:
This is simply control of the heater using the external ENABLE/DISABLE contacts, remote equipment contacts and the alarm contacts. See wiring diagram of equipment for details.

Stop Bits: 1 (Not adjustable)
Start/Stop: Silent interval of 3 characters minimum
Minimum Time Between Retry: 500 msec.
Maximum read command is 5 words
Steps to change the TempTrac MODBUS address:
Editing parameters should be done without any device trying to communicate through the MODBUS port.
To avoid interference from a gateway or BAS, you should unplug the MODBUS adapter port on the back of the TempTrac at the white header, while making changes to the TempTrac parameters.
The first step to interfacing with a TempTrac or group of TempTracs will be the assignment of the address number for each boiler. The default for TempTrac is Address #1. You can assign any number in the range of 1-247. This is the limitations of the MODBUS RTU standard.
The MODBUS address is the Adr parameter, and it is in the Pr2 menu.
Enter the Programming mode by pressing the SET and DOWN key for more than 3 seconds. (Lead with the SET key.)
Pressing the DOWN key, parameters will display in top, and value in bottom.
Select Pr2 / PAS (parameter / value), and press the SET key.
The lower display will show the value 0 - - with a flashing zero.
Use UP or DOWN keys to input the security code in the flashing digit; confirm each digit by pressing SET. The security code is 321.
After hitting SET on the last digit, you will be in the Pr2 menu.
Once you have entered the Pr2 menu press the DOWN key to move through the parameters until the Adr parameter appears on the top display.
Now press the SET key once and the value number will begin to blink. Use the arrow key to set the address and then hit the SET key.
After hitting the SET, it will automatically go to the next parameter. Let it time out, or cycle power to the TempTrac.
Each TempTrac on a RS-485 network must have a unique MODBUS address.
The TempTrac MODBUS adapter port:
The MODBUS adapter is an orange dongle with 2 green screw terminals attached to an 8 inch cable that plugs into the back of the TempTrac at a white header. This can be an option installed on heater, or it may be a separate line item part. When the option is available, it is MBUSC option code. As a standalone part, it is PN: 11807.

TEMPTRAC PROTOCOL
The MODBUS RTU protocol is well established industry protocol and technical references for this are readily available on the Internet.
Data Types Used
The TempTrac only uses one data type
Holding Registers (40001
– 49999) Read/Write
Other data types such as Coils are not implemented in the TempTrac control.
Only the data points in the POINTS LIST should be accessed.
Physical Layer RS-485
MODBUS RTU uses the physical layer RS-485.
RS-485 (EIA-485): A 2 wire (twisted pair) multi drop network. Each device can send data by holding positive and negative voltage on the line and reversing polarity on the 2 wires. When no devices are transmitting, the line will be tristate. The recommended arrangement of the wires is as a connected series of point-topoint (multi-dropped) nodes, i.e. a line or bus, not a star, ring, or multiply connected network. The number of devices that can be connected to a single line is defined in the RS-485 standard by the input impedance of 32 UNIT LOADs. The wire and circuits interfacing on this 2 wire connection is considered the PHYSICAL
LAYER. (RS-485 is the same physical layer as used with BACNET MSTP.)
No provisions for biasing resistors or termination resistors are provided on the control. If required, this will need to be provided externally.
The PVI gateway does provide optional biasing (default) and can provide a termination resistor, if required.

WIRING BAS TO GATEWAY AND THEN GATEWAY TO TEMPTRAC:
Each gateway has 3 connection points.
The 6 position terminal block contains connection for power and MODBUS RTU (going to heaters).
The Ethernet port is for configuration, BACNET IP, or MODBUS TCP.
The 3 or 2 pin terminal is for the BAS interface: BACNET MSTP, or LONWORKS.
Power Connection:
Gateway power supply, 6 position terminal +PWR, -PWR.
Use supplied wall wart style power supply. 15VDC. Do not power other devices with same power supply.
If power adapter has not already been connected, cut and discard the connector on the end, strip and terminate the power adapter in the proper terminals. Verify polarity. If another supply is to be used, it must be isolated. Do not use 24VAC power from heater.
Gateway Connection to Heaters:
Wiring from Gateway to the heaters, use twisted pair wire.
Connector on the orange dongle adapter that is on the end of a 8” cable plugged into the back of the
TempTrac.
The wiring is standard 2 wire RS-485 wiring. You will connect all devices together in a daisy chain. We recommend the gateway to be at the start of this connection.

GATEWAY CONFIGURATION CONNECTION:
Both the LONWORKS and BACNET gateway have an Ethernet port. Connect the computer using a patch cable or cross-over cable to establish a direct connection to the gateway. Older units may require a crossover cable or two patch cables with an Ethernet switch. If using BACNET IP or MODBUS TCP interface, connect the BAS Ethernet cable to the gateway when configuration is complete.
At this point, each heater and the gateway should all be powered, and have all wiring finished. The RUN
LED will toggle every second to indicate the gateway is running.

CONFIRM OPERATION:
Heater Communication:
Communication between gateway and heaters is evident by rapid flashing of the TX and RX LEDs on the gateway. If only the TX is flashing (may be as slow as 30 seconds between flashes), that will indicate no response from the heaters.
Building Automation System Communication:
Using the HTML interface, you can confirm some operations and under USER MESSAGES, confirm there are no errors messages. At this point, the BAS will need to discover the gateway and implement the points into its integration.
TROUBLESHOOTING GATEWAY:
ï‚· ERR Red LED on o Gateway is reporting an error. o Connect to gateway with HTML interface to view error messages
ï‚· PWR LED not on o Confirm power on +PWR and
–PWR
ï‚· TX & RX not flashing o Confirm connections to heaters and MODBUS addressing o Confirm gateway has been configured
ï‚· TX flashing, RX not flashing o Gateway is talking to TempTrac, but not getting response from TempTrac. Confirm wiring, confirm TempTrac is configured to proper address, Baud, Parity, Stop bits.

NOTE: This point is not generated by the heater; it is generated internally by the gateway. It is a status of the communication connection between the gateway and the heater. If active (GOOD), the gateway is talking to the heater. If inactive (NOT_PRESENT) then the gateway does not have good communication with the heater. This point may take up to 3 minutes to register properly after communication is established or interrupted. If this value if reading NOT_PRESENT, then no all over values are suspect, as the device is not communicating.
Generally the Gateway will hold the last value received. The only way to ensure you have the current values from the heater is to verify this point is ACTIVE as well.
