The panel has seven built-in Delay Timers 
that insure safe & reliable operation.

When all zone demands are 
satisfied, the panel will not resume 
the same mode of operation for a 
minimum of   3 minutes.

A built-in timer prevents the system 
from rapidly switching between 
heating and cooling modes. At the 
end of a call, a 4 minute timer is 
started and the panel will not switch to 
the opposing mode until the timer has 
expired.

The STAGING TIMER sets the 
amount of   continuous call time in 1st 
stage, before second stage heat or 
cool is energized. 

NOTE: 

The 

potentiometer also serves as the

 

Outside Air Changeover Setting.

The BMPlus 3000 can inhibit heat 
staging based on a

NOTE:

 

An Optional OAS Sensor is 

required to use the OAS feature.   

NOTE:

 2nd stage cool delay defaults 

to 30 minutes, if OAS is chosen to 
inhibit 2nd stage Heat.

   Delay Timer

A 20 minute delay must expire, or the
active zone(s) must satisfy, before
the panel will honor a thermostat 
demand to changeover to the 
opposite mode of system operation.

 *Supply Air
   Limit
   Delay Timer

The time delay of 3 minutes must 
expire before the BMPlus 3000 will 
re-energize heat or cool mode. This 
delay occurs when the processor 
detects the supply air temperature is 
higher or lower than the High or Low 
temperature limit settings.

The Adjustable 2nd stage heat 
differential potentiometer sets the 2nd 
stage heat supply air temperature, at 
which the heating is cycled off and the 
fan continues to run, allowing the heat 
exchanger or coil to cool down. 

NOTE:

 Allows the supply air sensor to 

be installed in the supply air plenum, 
regardless of the coil/heat exchanger 
configuration. Allows the installer to fine 
tune virtually any multi stage heating 
system!

An On-Board Switch is provided that 
allows the Customer to set the system 
to the Emergency heat mode. 

This switch is shown in the NORMAL 
position.

This switch would be used for Heat

Customer chooses to use Regular

The separate reset buttons on the 
old BMP3000 have been replaced by 
a single button with dual functions. 

Momentarily pressing the  RESET 
button clears the built-in timers 
controlling the Startup delay timer, 
Short cycle timer, W2 timer, Supply air 
sensor timer and the Changeover 
timer. This enables you to test the 
installation faster.

 

Caution should be 

observed when using this button. 

Always reset the CPU 
anytime you make 
dip-switch changes to 
the BMP3000 panel!

DO NOT use a sharp 
object to press the 
button! Your finger tip 
will work fine.

Pressing the RESET button for 7 
seconds will reset the CPU for 
the entire zone system.

*Startup
  Delay
  Timer

The panel will not activate any 
cooling or heating operation until 
the startup delay has expired. This 
occurs after any initial power up or 
power failure. Press the 

Reset

 

button for 1 second to override.

* Start-up Delay Timer = 3 minutes-fixed
* Short Cycle Timer     = 3 minutes-fixed
* Change Over Timer  = 4 minutes-fixed
* Opposing Call Timer = 20minutes-fixed
* Staging Timer = OFF or 7-42 min. -Adj.
* Supply Air Limit Timer = 3minutes-fixed
* Purge Delay Timer  = 90 seconds-fixed

 *Purge Delay 
  Timer

The last Damper(s) will be held Open 
for 90 seconds at the end of every call 
allowing a system purge into the last 
zone that was calling.

Any setting 
below 7 is off!
DO NOT set to off 
if using OAS
