If the TempTrac Control Module is applied in the (FULL CONTROL), R1 & R2 terminals will interrupt the
operation of the boiler and T1 and T2 terminals will provide a 4 to 20mA signal to modulate the firing
rate of the burner. If applied, terminals A1 & A2 can be wired to an alarm input from the boiler. The
TempTrac control will communicate boiler water temperature to the OnTrac Multiple Boiler Control.
Alarm condition can also be communicated back to the OnTrac if the alarm input is wired to A1 & A2.
• The first step will be routing the operating circuit through the R1 & R2 terminals (15Amp Max).
This will also require that the existing operating control set-point be raised so as not to interrupt
the normal operation of the boiler. If this is not possible, the existing operating control must be
removed. WARNING: Do not bypass the existing boiler limits.
• Next, the existing modulation control must be disconnected and replaced with the modulation
signal from the TempTrac Control Module (T1 & T2).
• The temperature sensor must
be installed in a location that
allows the control module to
monitor the boiler water
temperature. If the sensor is
not installed in a thermal well,
care should be taken to find a
clean surface location near the
boiler outlet and insulate the
junction well. The sensor probe
dimensions are: ¼” dia x 1 ¾”
long. The wire length is 5ft but
can be increased to up to
100ft.
•
The alarm terminals (A1 & A2)
require a 120Vac input to indicate an alarm condition to the OnTrac.
