INSTALLATION:
WIRING THE 30120
First of all, decide if the wire is going to run through the
bottom or back opening. In case of running the wire
through the bottom opening, remove the plastic plug by
sliding outward. For hydronic heating system, run a pair of
wire (18-20AWG) from each of P-03 sensor to the
corresponding terminal blocks:
Sensor of Supply Piping to “T1 T1” or “OUT”.
Sensor of Return Piping to “T2 T2” or “IN”.
For other systems, T1 corresponds to location 1 and T2
corresponds to location 2 of the sensors.
When 24VAC input is applied, the power consumption
from the lithium battery will be disabled. Always pull away
the plastic tab from the battery to activate the battery
power or as backup power.
INST ALLING THE FRONT COVER
This is the reverse process of removing the front cover.
The hinges on the bottom of the front cover can be aligned
with the base to provide pivot for the front cover to close.
Swing the top part of the front cover all the way until it
snaps tightly with the base.
OTHER OPERATION ISSUES:
OUT OF RANGE
If the temperature is under -58 F (-50 C), “LLL” will be
displayed
If the temperature is over 302 F (150 C), “HHH” will be
displayed
LOW BATTER Y INDICATOR
If the battery is low, symbol will be flashing.
Change the battery as soon as possible.

MOUNTING THE SENSOR:
The sensor 30121 is designed to strap on a pipe or
insert onto a temperature immersion well.
Sensors should be strapped to the pipe with cable tie.
The flat side of the sensor should be resting on the pipe. In
addition, they should be covered with a layer of insulation
to minimize the effects of ambient temperature for a more
reliable temperature reading.
The sensor 30121 can also be insert onto a 3/8”(10mm)
or ½”(12.7mm) ID temperature well.

Note: Do not run sensor wires parallel to other electrical wiring
or telephone wires. In case there is strong source of
electromagnetic interference, twisted pair 20AWG wire is
recommended.
