1. Features
This thermometer can be used for stove pipe and chimney temperature monitoring.
The meter contains two alarm settings for the built-in buzzer. One can be used for high
limit alarm and the other can be used for low fuel alarm. It also has a third alarm for
the connected external buzzer that can be placed at different floor from where the
stove is located. The gauge is powered by 12V DC through an AC adapter (included)
for continuous operation. It can also be powered by car battery.
5. Parameter Setting
POWER - 12V Power supply input
OUT - Output for external buzzer
INPUT - Temperature probe input
Figure 2 shows the terminals of the meter. Connect the 12V DC power adapter to the
terminal 1 and wall outlet. Connect the external buzzer connector to terminal 2. The
polarity for this socket is center pin positive (+), outer collar negative ( ). Connect the
K thermocouple to terminal 3. Please note that thermocouple connector also has
polarity. The wide blade should go to the wide slot.
4. Connecting the meter
Note 1. Set Alarm for external buzzer.
There are two ways to set the external alarm temperature.
a. During the normal operation mode, press Λ or V once to switch the display from
process value (PV) to set value (SV, or target temperature). The display will start to
blink. Press Λ or V again to increase or decrease the SV. When finished, wait 8
seconds and the settings will take effect automatically (the display will stop blinking).
b. Press SET key once. Use >, Λ and V keys to enter code 0001. Press SET key to
confirm, then the display would be SV (
Su
). Press SET key again to display the SV
setting. Use >, Λ and V keys to enter the new SV value and press SET to confirm.
Press V key to change the display to END. Then, press SET to exit. You can also
ignore the steps after confirmation of SV. The controller will return to normal operation
mode automatically if no key is pressed for 1 minute. The flow chart below shows how
to set the SV and alarms in details.
The default setting for the external buzzer is high limit alarm (see Note 6). The external
buzzer will be on when the tempeature is above SV+Hy (see Note 5), will be off when
the temperature drops back to SV.
