The optional remote console is shipped separately. Remote consoles include terminal
blocks for wiring. If ordered with a remote console, the toggle switch is mounted on
the console and depending on what gas control option was ordered, the console could
include a temperature selector. If a dirty filter switch is ordered the indicator light is on
the console. See FIGURE 22 for console size.

CAUTION: Supply voltage and 24-volt control wiring cannot be
installed in the same conduit. Maxitrol systems will be adversely
affected if control wiring is in conduit with supply voltage wiring. If
required, field-supplied wiring between any Maxitrol components
must be completed with shielded wiring.
7.3 Control Wiring Refer to FIGURE 21 for location of control wiring connection. Low voltage wiring must
be in individual conduit, separated from primary high voltage wiring.
A 3-position control switch is supplied with each system, either packed loose inside the
unit, or if an optional control console is ordered, the switch is mounted on the console.
Control wiring requirements depend on the options selected. Follow the custom wiring
diagram supplied with the system to connect any remote controls. For additional ref-
erence, the control manufacturer's instructions are included in the owner's envelope.
