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
.
Max SP
Boilers
230
140 to 230 F
The Maximum Operational Setpoint for all possible Local and Remote modes.
Min SP
70
60 to 230 F
The Minimum Operational Setpoint is the lower limit for all Local and Remote
modes.
Min BIT
120
60 to 235 F
Low Boiler Inlet Temperature alarm and event setpoint.
Min In H2O
Temp
130
110 to 180 F
Minimum Inlet Water Temperature setpoint used as the Mixing Valve inlet
temperature setpoint.
Only visible when
Mixing Valve
equals
Yes
.
Max H2O
Delta T
50
20 to 50 F
Maximum Water Differential (Boiler Outlet minus Boiler Inlet) Temperature
setpoint used as the Mixing Valve differential temperature setpoint.
Only visible when
Mixing Valve
equals
Yes
.
Max
Delta T
Hold
50
20 to 50 F
Maximum Water Differential (Boiler Outlet minus Boiler Inlet) Temperature used
to hold modulation rate at low fire.
