When the tank temperature and/or 0-10V BMS voltage is
provided by the BAS to the appliance, it is critical that the
values be updated every few seconds. If the appliance does
not receive updated values within a timeout period (installer
adjustable), the control will revert to using its own readings
(if connected). Th e timeout is programmable by accessing
parameter H6 (see the Armor Service Manual for instructions
for setting parameters). Th e timeout is adjustable between 5
and 120 seconds. Th e default timeout is 10 seconds.
When the BAS is not providing any of these values, but is
still controlling the appliance (such as providing an enable
command), the BAS must refresh these commands at least
every 4 minutes. If the commands are not refreshed, the
appliance will revert to operating based on its own inputs.

Communication Board Diagnostics

Th e Communication board is equipped with three LED's for
visual diagnostics: Two yellow LED's and one green. One
yellow LED (D5) is used to indicate transmission of data. Th e
other yellow LED (D6) is used to indicate reception of data.
Th e green LED (D7) is used to show internal faults.

Internal Faults:

Normal Operation = 1 second bright, 1 second dim
Controller Fault = Continuously on
No Burner Control Communication = 0.5 seconds on, 1.5
seconds off
No BACnet Communication = 1.5 seconds on, 0.5 seconds
off .
