be used on frost protection systems. This application allows for wind machine, sprinkler or other forms
of frost protection using single contact or a temperature transducer.
The auto start functions and auto throttle methods to choose from are listed below.

Start/Stop Timers
The Start/Stop Timers menu provides the operator the ability to add a countdown timer and start/stop times.
The countdown timer allows for the operator to set a desired countdown time and walk away from the engine
for a controlled shutdown when the timer expires. There are eight Start/Stop Timers the operator can choose
from within this menu that allows for the specific day and hour the controller will start and stop utilizing the
internal clock. Review Start/Stop Timers under Menu Glossary section of this manual for full list and definition
of each setting.
Start/Stop timers work in conjunction with other Start/Stop types but independently as Start/Stop functions. If
the engine is already running from a Start/Stop type when a Start/Stop timer occurs, the Start/Stop timer is
ignored. Once the engine is started by the Start/Stop timer, other Start/Stop types will be ignored until the
timer expires and a controlled shutdown occurs.
Communication
The Communications menu allows the operator to choose the type of RS485 communications such as Modbus
or Local Display. The menu also allows for the operator to choose the RS485 slave address, RS485 Serial
setup and whether or not the controller uses the internal CAN terminating resistor. Review Communication
under the Menu Glossary section of this manual for a full list and definition of each setting.
Auto Start/Stop Functions Defined
There are eight automatic start/stop types in the MPC-20-R2 and are shown relative to the application chosen
as shown in the previous section. Each is detailed below:
Single Contact Start/Stop
The Single Contact Start/Stop occurs when a remote contact is active for auto start and inactive for auto stop.
Think of this as a toggle switch, on or off for remote starting the engine. Requires one digital input for this
start/stop type.
Local Start Key Start/Stop
The Local Start Key Start/Stop is used to remove any other auto start/stop types within the controller, if they
are not needed. This auto start type still allows the controller to run through the auto states of the controller.
