PUMP CONTROL
There are six identical pump control blocks. Each has a
different name but are entirely equal in features and
capabilities. For example, if the block named CH Pump were
configured to control the DHW pump and vice versa, and the
pumps were hooked up that way, both pumps would work
normally. Each can be configured for any purpose without
regard to the pump name. See Fig. 21.
THERE ARE 6 PUMP CONTROL BLOCKS THAT ARE FUNCTIONALLY IDENTICAL EACH HAS
7 PARAMETERS THAT WORK THE SAME WAY IN EACH BLOCK. SEE PumpControlBlock.evx

Pump Control Block Parameters
Each pump control block implements the parameters
described in Table 30, where "XX" is a placeholder for any of
the six pump names (CH, DHW, Boiler, System, Aux1, or
Aux2).
• Normal pump demand: These bits are in the lower left of
Fig. 22, and each of them enable or disable pump demand
that flows through the start delay and overrun time, to the
"On" connection of the physical device as shown in Fig. 22.
This form of pump demand may be inhibited by Force Off.
The pump names are:
• Boiler
• CH
• DHW
• Aux1
• Aux2
• System
Pump control blocks can operate for a local Falcon, a LL
Master, or both. Some pump demands are always from the
local controller, some from the LL Master and some may come
from either source.
The pump overrun timers for frost protection are part of the
frost protection block, instead of the pump control block.
