tion RT11 if factory

mounted on an

optional console,

Paragraph 8.2)

Control works with either cooling or heating, providing zone tem-

perature sensing, occupied setpoint boost (-3° cooling; 4° heat-

ing) and unoccupied override button, and LED fan and alarm

status for cooling. Provides space temperature identification only

(no space adjustment).

Depending on how it is ordered, the control is shipped separately for field instal-

lation or factory-mounted on a shipped-separate console. Follow the instruc-

Optional Controls used only with System Control Option D12A (FX06 Controller)

The wall or console mounted sensor should be

located on an interior wall (avoid direct place-

ment in the sun) with the wall opening insulated

to prevent cold drafts. Locate the sensor where

it will sample representative space air.
The optional space sensor with setpoint adjust

transfers the data back to the unit controller. The sensor requires 24VAC power

and two wire communication. See the unit wiring diagram for wiring details.
