Description
If DHW is the active service controlling the heating system (has heat
demand AND is in control) then this pump will have normal pump-on
demand.
If DHW is calling for heat then this pump will have normal pump-on
demand. A DHW call-for-heat will operate the pump even if some
other service source (e.g. CH) is actually in control of the boiler on
higher priority.
If DHW is the active service controlling the heating system (has heat
demand AND is in control) then this pump will have normal pump-on
demand.
This pump will respond when LL service is currently the highest priority
service for this slave and the Sola LL master has commanded this slave
Sola to start up and fire.
If CH frost protection is active then this pump will have normal pump-
on demand.
If DHW frost protection is active then this pump will have normal
pump-on demand.
If Local demands are enabled, then when the burner has demand (is
firing or preparing to fire, always local) the output will be forced on.
Example, this feature might be used to open a boiler room air damper
(but does NOT implement airflow safety).
If Sola LL Master demand is enabled, then whenever the master is asking
for heat from any slave, this output will be forced on. Example, this
feature might be used to open a boiler room air damper (but does Not
implement airflow safety).
If the local Sola is disabled (e.g. via the burner switch parameter) or
locked out, inhibit local demand sources (are selected) that might
otherwise request the pump to be on. Otherwise these will run the
pump even though the sola cannot fire.
(continued)
The Pump can be turned on manually, or it can be set to operate
automatically. If it is turned on then it remains on until changed back to
Auto. In Auto mode it operates according to the demand sources listed
above and the overrun time.
This parameter allows the Pump function to be disabled or to activate
any of the three pump outputs on terminal strip D.
This time indicates how long the Pump should remain on after demand
from any source ends. That is, whenever the pump has been on, but the
last requests for the pump to be on ends, it always continues to run for
the time given by this parameter.
Enables pump demand from the local Sola: the one which contains this
pump control block. If not enabled then all local Sola pump demands are
ignored by this pump control block.
