8.3.7 Auto-Manager Transfer
The Auto-Manager Transfer feature, once enabled, automatically transfers WHM Manager
functionality to a new unit if the current WHM Manager fails or loses power.
To use this feature (default = Disabled), go to:
Main Menu
→
Advanced Setup
→
WHM
Cascade
→
Cascade Configuration
on the unite designated as the WHM Manager
and set
Auto-Manager Transfer
to
Enabled
, then choose address of the backup unit in the
Backup
Manager Addr
parameter. You can also specify a delay before transferring manager
functionality in the
Auto-Manager Timer
parameter.
8.3.8 Run Hours and Run Cycles
Run hours and run cycles are monitored to select the Lead unit and Lag unit (next on unit) in a
WHM Cascade. In the event an
Edge
or PMC board is exchanged in the field, this feature will
allow the user to increase but not decrease the run hours or run cycles. Once a user hits enter,
the changes made will be permanent and this feature will not allow changing to the previous
value.
Only AERCO personnel are permitted to change this menu item. To increase the
Run Hours
or
Run Cycles
, go to
Main Menu
→
Advanced Setup
→
Unit
→
Unit Settings
.
8.3.9 High Temperature Governor
The High Temperature Governor is a feature that aggressively prevents the outlet temperature
from exceeding the “Temperature High Limit”. The High Temperature Governor is independent
of the system PID and Feed-Forward control methodology and independently modulates the
Valve Position (Fire Rate) if the outlet temperature dangerously approaches the
Temperature
Hi
Limit
parameter.
This feature has 5 separate temperature bands for more precise control.
This feature is enabled by the
TEMP GOV
parameter in
Main Menu
→
Advanced Setup
→
Performance
→
Temperature Control
→
FFWD Settings
. Once enabled, the 5
“governor”
items,
GOV Limit-5
to
GOV Limit-15
are available. When the Outlet Temperature exceeds the
value of the
Temperature Hi
Limit
parameter (in
Main Menu
→
Advanced Setup
→
Performance
→
Temperature Control
→
Temperature Conformance
) the effective Fire Rate
will be reduced by the value entered in
GOV Limit-5
through
GOV Limit-15
.
