Laboratory Room Controller and Enclosure

Item Number 546-00330, Rev. BA Page 1 of 6

Product Description

The Laboratory Room Controller (LRC) is a multi-

application equipment controller designed to provide

Direct Digital Control (DDC) for a laboratory room

with a single fume hood controller, or up to four fume

hood controllers through a Fume Hood Flow Module

(FFM). The LRC, which controls room temperature

and pressurization, can operate stand-alone, with a

field panel, or as part of a network.

Required Tools

• Medium slotted screwdriver

• 1/8-inch flat-blade screwdriver

• Medium Phillips head screwdriver

• 1/4-inch nut driver

• Hammer

• Electric drill

• 1/2-inch drill bit

• Four 4-inch spring wing toggle bolts with

mushroom heads

• Four washers (1/4-inch ID, 3/4-inch OD)

• Four anchors (sleeve or stud)

• Level

• Marker

• Tape measure

• Pencil

Expected Installation Time

45 minutes

Prerequisites

• The enclosure should be at least 5 feet away

from large motors and radio equipment.

• Field level network (FLN) with 24-volt wiring

roughed in.

• All damper and valve actuators are installed.

Mounting Instructions

1. Remove the enclosure cover.

2. Remove the appropriate conduit knockouts. See

Figure 1.

3. On the wall or the surface on which you will

mount the enclosure, measure and mark a level

line.

4. Align the top edge of the enclosure on the level

line made in Step 3. Mark the position of the four

mounting holes on the rear panel of the

enclosure.

5. Drill the two mounting holes. Insert the wall

anchors.

CAUTION:

When hanging the controller, it is

recommended that you use the enclosure

mounting holes as a template for marking

the holes on the wall. The metal shavings

from drilling new holes in the controller can

cause severe damage to the controller.

6. Place the washers on the mounting bolts. Mount

the enclosure on the wall.

For applications that use the electronic actuator, connect a certified 24 Vac Class II power source to each unit on terminal block J1. Separate power sources may not be used for the electronic actuator and the LRC. WARNING: This actuator requires a maximum of 20 VA, 24 Vac source. DO NOT connect any other non-isolated devices to the transformer that powers the electronic actuator. 7.
