Ashby-P Insert
Page 27
Control Board Features
The Control Board controls all functions of the
Ashby-P by monitoring sensors that are in the
system. These sensors serve 2 purposes.
a.
General Operation of the Insert.
b.
Safety Features, to shut the unit down in
the event the sensors detect a problem in the unit.
The
Control
Board
also
has
Diagnostic
Capabilities to help in diagnosing 3 areas in the
Insert. These areas are:
1.
High Temperature Limit.
2.
Proof of Fire Sensor
3.
Vacuum in the Firebox
A closer look at the Control Board to the right in
figure 16 will explain how the board works.
The ON/OFF button, The Auger Feed Button
(used to prime the Pot with Fuel) and the
Heat
Level
and
Draft
Trim
Buttons. The last 2 buttons
have High and Low buttons to advance/adjust
these settings up or down. There is a slide switch
that controls the Thermostat Mode and an LED
Light bar that indicates which of the 5 Heat
Settings the Stove is running on.
Figure 16
The LED Light bar is also used during the Diagnostic process, see page 34 for more details
1. The Heat Level button will advance the setting up and down between level 1 and 5. It will
also be used in the Fine Tuning process of the feed rates if needed.
(See point 4 b
)
2. The Auger Feed button will allow the user to manually auger fuel into the burn pot on start
up when needed. This is particularly helpful in priming the Auger Tube when it is empty (After
the hopper has run out of pellets).
Do not tamper with the Auger Feed button to override the
automated feed system. This may cause the unit to Overheat.
To adjust the Feed-rates:
Hold the Auger Feed Button down and press the Heat Level High/Low button and this will
change the ON Time up or down .25 seconds from the factory setting. Watch the LED lights
to see the setting is on (it will flash the new setting). This new setting will stay in memory
from this point on.
