BPE24 Installation Instructions #BPE24

FORM BPE
The BPE24 is a very simple control to troubleshoot,
especially with the LCD Display. The only other device
needed is a simple Volt/Ohm meter.
Almost all problems can be traced to an external component
or wiring to the BPE24. While the BPE24 has been
designed to operate under extreme voltage conditions and is
fuse protected, like any computer the micro-processor can
hang up and not operate properly.
Turn off the power to the panel for several seconds until the
LCD goes out, and then turn the power back on to see if the
panel resets. In many instances this resolves the problem.
The first check is for 24VAC Power to the panel. When
there is power the LCD will be lit. If not check the
transformer and the power supply to it.
Zone(s) Not Closing
If a zone is not closing and there is an active HVAC call it
may be that there is an excessive amount of air being
bypassed into the zone. End all HVAC calls and using the
damper test button on the Main Controller you can check to
see if the dampers are properly cycling.
Damper Motor Checkout Procedure
To check out the dampers, the panel supplies 24VAC to the
COM and OPEN when the damper is to be open and
24VAC to COM and CLOSE when the damper is to be
CLOSED. When any zone is calling and its Green LED is
ON, there is 24VAC across COM and OPEN. The only time
a damper will close is when anther zone is calling and its
zone is not calling. In this instance there will be 24VAC
between COM and CLOSE.
