Range/Choices Description
Operational
SP
180 60 to 230 F
Setpoint used in Local Setpoint Mode when not servicing a Domestic Hot Water
Priority (DHWP) request.
On Point -5 0 to 99 F
The boiler starts when the water temperature drops ‘On Point’ degrees below the
setpoint.
Off Point 15 0 to 99 F
The boiler stops when the water temperature rises ‘Off Point’ degrees above the
setpoint.
High Temp
Stop
Boilers
230
60 to 230 F
The boiler stops when water temperature is above the High Temperature Stop
setpoint. This setpoint is active in every control mode.
DHWP
Setpoint
180
140 to 230 F
The Domestic Hot Water Priority (DHWP) Setpoint is active when DHW Input
(DP) closes and “DHWP” parameter is set to “yes” and Local SP Mode is
selected. When the contact is closed, the boiler outlet is maintained at, or above,
the DHW Setpoint.
Only visible when DHWP equals Yes.
WWSD
Setpoint
70 40 to 90 F
The Warm Weather Shutdown (WWSD) Setpoint used to disable boiler and or
system pump operation when enabled by setting the “WWSD” parameter to
“WWSD of Boiler”, “WWSD of Sys Pump” or “Both”.
Only visible when WWSD does not equal Off.
