When non-Riverside Hydronics boilers are controlled by the OnTrac boiler management system, the
optional TempTrac Boiler Control module can be applied as a fully functional operating control or used
to enable and disable only.
The communication interface is made as described on page 5 of this manual. Each TempTrac Control
Module will be wired in a daisy chain fashion along with the other boilers in the OnTrac system. See the
terminal illustration on the following page for connections.
The TempTrac must be assigned an individual address in order to communicate with the OnTrac. See
“ASSIGNING BOILER ADDRESSES” on in the OnTrac Programming Manual 34-152.
If the module is applied as an enable/disable (ON/OFF ONLY), the R1 & R2 terminals will interrupt the
operating circuit of the boiler. The modulation, staging and primary temperature regulation function will
be controlled by the existing boiler controls. WARNING: Do not disable the existing boiler controls or
bypass the existing temperature limits. When the (ON/OFF ONLY) function is used the TempTrac
temperature sensor can be used for displaying the boiler temperature only or left to display the room
temperature. The sensor is coiled and placed inside the enclosure. Do not disconnect sensor.
