Boiler Manual

Option

Activation conditions

Suggested uses

ALWAYS ON

• Output is always energized whenever the control is powered.

• Hot loop for seasonal boilers that are manually

shut down at end of season and started up at
start of heating season.

EXTERNAL
SWITCH

• The output is energized on closure of an external switch wired to this

input and is de-energized when the external switch opens.

• Hot loop for boilers whose CH is manually

shut down at end of season and started up at
start of heating season, but remain available for
local calls (DHW, etc.).

OUTDOOR
BELOW WWSD

• This output is energized only when outdoor temperature is below the

WWSD setting (see BOILER SETTINGS menu, Figure 70, page 80 ).

• This setting is non-selectable if WWSD is set to OFF or ODT is not

connected at initial boiler power. If Outdoor Below WWSD is already
chosen and WWSD is later set to OFF, Outdoor Below WWSD will
behave as Always On.

• Hot loop for boilers whose CH is automati-

cally shut down based on outdoor temperature
(inferred heat loss), but remain on for local
calls (DHW, etc.).

ANY TT INPUT

• The assigned output is energized if there is an input closure on this boiler.

• The assigned output will de-energize once there are; no input on this

boiler, post-purge has ﬁ nished and post-pump time has expired.

• If the closed input is conﬁ gured for a heat demand, its output will de-

energize after post-purge and post-pump.

• Energize a system pump relay if pump must

run during all heating calls.

ANY TT INPUT
BY ITS PRIORITY
SETTINGS

• The assigned output is energized:

• If there is an input closure on this boiler.

. . .

and

. . .

• RUN AUX PUMP/OUTPUT is set to YES for the priority as-

signed to the closed input.

• The assigned output will de-energize once there are no input closures

on any of the network boilers, post-purge has ﬁ nished, and post-pump
time has expired.

• Energize a system pump relay if pump must

run only on some heat calls (such as systems
with locally-connected DHW heating).

BURNER
DEMAND

• The assigned output is energized when the boiler receives a call for

heat and starts to pre-purge.

• The assigned output is de-energized once the burner is off and post-

purge is complete.

• Use for interlocking with combustion air

damper, ﬂ ow switch, etc.
