SECTION 6 – ADVANCED SETUP
SH BST Fire Rate Up: Controls the frequency of updates made to the BST Fire
•
Rate sent to all boilers focused on space heating. This feature can be used to slow
down the rate of change of the Fire Rate of the BST System. (Range: 1 to 120 sec.)
SH High-Fire Fire Rate: This parameter specifies the firing rate above which the
•
swing boiler will be requested to support the SH loop application (Range: 75 to 100)
SH Low-Fire Fire Rate: This parameter specifies the firing rate below which the
•
swing boiler will be released to its default state. (Range: 30 to 60)
DHW High-Fire Fire Rate: This parameter specifies the firing rate above which the
•
swing boiler will be requested to support the DHW loop application (Range: 40 to 90)
High Fire Threshold Timer: This parameter specifies the amount of time between
•
when the SH High-Fire Fire Rate or DHW High-Fire Fire Rate condition is met
and the time the swing unit switches over to the secondary application.
(Range: 1 to 30 mins.)
DHW Pump Off Time: The minimum time the DHW pump must stay off before
•
restarting after being turned off. (Range: 0 to 600 sec.)
DHW BST Fire Rate Up: Controls the frequency of updates made to the BST Fire
•
Rate sent to all boilers focused on domestic hot water generation in a combination
plant. Like SH BST Fire Rate Up, this feature can be used to slow down the rate of
change of the Fire Rate of the BST System. (Range: 1 to 120 sec.)
