Control Arrangements
The LMHS single duct and RVE / SVE retrofit units are offered with a wide variety of factory-mounted
controls that regulate the volume of air delivery from the unit and respond to cooling and heating
load requirements of the conditioned space. These devices are available in both pneumatic and
electronic arrangements. Some DDC (Direct Digital Controls) control packages provided by others
are also available for consignment mounting.
The following listings contain the basic function arrangements for each control offering. Circuit
diagrams, operating sequences, and function descriptions are contained in separate Application
Data publications because of the variety of functions available. Refer to the specific control
publication for details.
Direct Digital Electronic Control Arrangement (Field Supplied) - Control packages are field supplied
for factory mounting, unless otherwise noted. All DDC control arrangements include an inlet flow
sensor, 24V transformer (optional), and control enclosure. Contact the factory for details about
mounting field-supplied controls.
Analog Electronic Control Arrangement - Pressure independent control packages are available
without supplemental heat, with on/off hot water or electric heat, proportional hot water heat, or with
cooling/heating automatic changeover control. All analog control arrangements include an inlet flow
sensor, 24V transformer (optional), control enclosure, and wall thermostat with LCD display.
