Baseload common (i) “BL” for baseload (ii)User
selection 0 – 100 % (d)Use existing timeout,
Done button, and Next button functionality to
enter these parameters. (e)User selections will
be selected by MMI. (i) The local display does
not adhere to the PCB (OEM parameter
selections used by S7999). (5) In normal display
operation the display allows a user to scroll
through a list of temperatures with associated
icons (CH, Inlet, Delta, DHW, Stack, Outdoor)
using the Next button. With LL active the display
will show the header temperature at the end of
the list of temperatures as follows: (a)The
characters “LL” are displayed in the number field
(b)When the next button is pressed again the
temperature is displayed. (c) If the Up or Down
buttons are pressed then the LL set-point is
changed. 5. System Display Configuration – The
following parameters are available for OEM
configuration and may be adjusted through a
System Display or programmed at the OEM
production facility. Master Sola Slave Sola LL

Slave Data Supporting Lead Lag
This data is provided by each slave Sola control
to support operation when a LL master exists.
The illustration below summarizes the slave's
registers and data:
LL Slave
Some slave changes relate to pump control,
frost protection, and also are available to 3
rd
party (non Sola) LL master devices. The generic
LL slave is updated to operate as shown by the
LL slave is updated to operate as shown by the
diagram below:
Frost protection requests
The frost protection in this status register will be
set or cleared to match the status generated by
the frost protection detection functions.

Firing for local frost protection
This
provides indication to the LL master that
although the burner is firing independently, it is
doing so for frost protection and thus is still
available as a lead/lag slave. This is set when 1)
frost protection is controlling the Sola per the
priority scheme (which occurs only if frost
protection is enabled), and 2) burner demand is
true and the burner is currently firing or
preparing to fire to serve that demand.
Otherwise it will be clear.

Aux Pump X, Y, and Z
The pump control in
the Slave can be used by previously existing
command devices to create the same behavior.
However before these bits controlled actions is
specific pump blocks, they are now more
general. The pump X, Y, and Z bits control
actions in any pump block defined to handle
them (see the pump control block definition).
