InputController (O)

activated

deactivated

Sets the function of INPUT X5-03.1. If activated, X5-03.1 must be energized to permit the
LMV5 to fire. This setting is typically used with a hardwired burner on-off switch. On an
LMV5 equipped with an internal load controller (LMV51.1 and higher), the internal load
controller may remove the call for heat and shut down the burner even if X5-03.1 is
energized. If deactivated, X5-03.1 has no function when in any internal load control mode.
The LMV5 can also be given permission to fire via Modbus if X5-03.1 is deactivated.

Config X5-03 (S)

LMV5x std

LMV2/3 std
LMV2/3 inv

DeaO2/Stp36

CoolFctStby

AutoDeactO2

Sets the function of INPUTS X5-03.2 and X5-03.3.
1) LMV5x std - floating bumping load control is retained.
2) LMV2/3 std or LMV2/3 inv - normal or inverted LMV5 2/3 staged oil functionality.
3) DeaO2/Stp36 - energizing terminal X5-03.2 disables O2 trim and de-energizing enables O2
trim (LMV52 only). Also, energizing terminal X5-03.3 allows the LMV5 to progress past phase
36 (de-energizing stops the LMV5 in phase 36 indefinitely).
4) CoolFctStby - only used on an LMV50.
5) AutoDeactO2 - energizing X5-03.2 will deactivate the O2 trim by setting the O2 trim mode
to "auto deact". O2 trim mode must be set to "ConAutoDeac" for the AutoDeactO2 to
function. De-energizing sets trim mode back to "ConAutoDeac".

GasPressureMin (O)

activated

deactivated
deact xOGP

Sets the function of INPUT X9-03.4 for the low gas pressure switch.
1) activated - input is expected to be energized when firing gas, or when using any oil train
that requires a gas pilot.
2) deactivated - terminal has no function.
3) deact xOGP - input is expected to be energized only when firing gas.

GasPressureMax (O)

activated

deactivated

Sets the function of INPUT X9-03.3 for a high gas pressure switch. Activate for gas fired
installations that use a high gas pressure switch.

OilPressureMin (O)

activated

deactivated

act from ts

Sets the function of INPUT X5-01.2 for a low oil pressure switch.
1) activated - input is expected to be energized by phase 38.
2) deactivated - terminal has no function.
3) act from ts - input is expected to be energized by phase 40.

OilPressureMax (O)

activated

deactivated

Sets the function of INPUT X5-02.2 for the high oil pressure switch.
