you see the 8 channels (numbered 0-7) and, if aktiv, the pitmaster.
It shows the actual-/target temperature and the actuator’s perfor-
mance from 0%-100%
If an alarm is set off a speaker symbol » appears in the left upper
corner and there is a acustic signal – the channel turns
red if the set temperature is exceed and blue if it falls below.
To cancle the acustic signal just press on the speaker symbol » it
will apear struck through. In case of another alarm there will be
again a acustic signal. The alarm will activate it self if all channels
are in the set termerature range again.

By presssing on a Channal » it is possible to set the min/max
temperature of the channel and select the type of probe you are
using. The meat symbol » allows you to select a variety of tem-
peratures for different meats.
Using the jack symbol » you can select the probe you are using.
Without a changeing the resistors in the hardware only the listed
probes can be used.
Tip: the original Maverick probe has a to long jack so it must not
be pluged all the way in. That would create a short and a nonsens
temperature reading.

5. Pitmaster:
With the Pitmaster it is possible to controll the temerature of a
grill or BBQ smokers using a fan or servo motor. Using a electrical
heatsource, SSR (SolideStateRelay) and a standard catering tray a
DIY Sous-Vide bath can be build.

trol curve
• Lid-monitoring : the thermometer dedects when the lid
is open and stops the pitmaster as long as the lid is not
closed again.
• Invert Controll : changes the direction of a servo motor, if a
fan is connected it will stand still at 100% and runns at full
speed at 0% and if using a relay the the NO or NC can be
switched.
