To set the Extension to a specific letter, remove the wiring cover and switch the Ext A/Ext B to the
desired letter. DO NOT set both extensions to the same letter to avoid errors.

M4-LHS
HYBRID CONTROL
• The M4-LHS is equipped with a RJ45 socket and a RJ45 to RJ11 Adaptor to connect to extension panels and X-SIG 4-20mA EMS
Interfaces. The Extension is equipped with two RJ11 sockets. It comes packaged with a RJ11 cable to connect to M4-LHS and an
additional Extension. Use the RJ45 to RJ11 Adaptor on the M4-LHS.
• The order in which the control, the extensions, and the interface are wired is not observed.
• Set each Extension to a different letter (EXT-A or EXT-B). The M4-LHS assigns the stage letters based on the extension letter
selected.
• Extension-A operates stages (E - J) and all the LEDs are Green. However, Extension-B operates stages (K - P) and all the LEDs
are Red. .
• Configure the Modulating and Sequencing Output Types after connecting the Extension panels to be able to configure their outputs.
See "Boiler Type" on page 19
• Use the 6-wire RJ11 cable supplied with the extension for proper operation.
