Series 2200 Relative Humidity and

Temperature Room Units For

APOGEE® Controllers

Page 1 of 5

Product Description

These room units measure relative humidity and

temperature in the occupied space in which they are

installed. Models with display allow users to view the

measured temperature value. A version with

temperature setpoint adjustment is also offered.

These devices are intended for use with appropriate

signal input on an APOGEE Controller. The effective

sensing range is 32°F to 122°F (0°C to 50°C), and

the setpoint range is 55°F to 95°F (13°C to 35°C).

These room units can be mounted on electrical

boxes, stud-type mounting brackets, or drywall.

Obtain the necessary mounting hardware and follow

the appropriate mounting procedures for the type of

installation required.

Mounting Information

Always mount the room unit vertically.

Locate the room unit:

•according to design specifications and local

regulations.

•where the air circulates around it freely (not in

recessed areas or behind doors).

•allowing a minimum of 4 inches (10 cm) free

space above and below for proper airflow, the

front cover removal tool, and the computer

communication cable.

•away from drafts caused by doors, windows,

outside walls, air registers, pipes, return air

plenums, etc.

•away from heat sources such as strong lights,

fireplaces, direct sunlight, etc.

•on an inside wall (preferably), about 5 feet

(1.5 m) above the finished floor.

Drywall Mounting (No Rough-in),

Typical

Base Plate Mounting and Wiring

1. Mark the center (cable) hole and the mounting hole

locations, using the room unit base plate as a

template. See Figure 3.

2. Drill two 3/16-inch (4.8 mm) mounting holes and

mount the two plastic wall anchors flush to below the

wall surface for stable mounting of the device.

3. Cut a 1-inch (25 mm) center hole with a hole saw.

NOTE: It is recommended that you use the

optional Insulating Gasket on the back of

the Sensor Base for hollow wall

installations.

When applying the adhesive-backed

gasket to the back of the Sensor Base,

orient the gasket so that the cut-out

arrow portion of the gasket is in the

upper lefthand quadrant of the Sensor

Base. The Sensor Base has an UP arrow

molded into the surface in the same

quadrant location (see Figure 6).

Figure 2. Insulating Gasket.

4. Pull about three inches (75 mm) of the cable through

the hole in the base plate.

5. Mount the room unit base plate on the wall, noting

the UP arrow:

NOTE: If required, position the Back Plate

behind the Room Unit Base, aligning the

top and bottom mounting holes, prior to

mounting to the wall:

a. Install the two mounting screws provided, but

do not tighten.

b. Level the room unit base plate for appearance.

c. Tighten the two mounting screws to the room

unit base plate.

6. Cut the cable, leaving about three inches (75 mm)

on the room unit side of the drywall. Ensure that pin

Number 1 connects to the same wire at each end of

the cable.

NOTE: See Figure 2 for details on optional Gasket

application.

7. Terminate the wires to the termination blocks on the

room unit's base plate. (See Figure 6.)

8. Feed the extra cable back through the hole.

(°F/°C Selector)

Voltage/Current

Selector Switch

Figure 4. Circuit Board

(Located inside Room Unit Cover.

1. If the device has a switch, determine if voltage or

current output is needed.

•For current, set the switch in the down position

(I).

•For voltage, set the switch in the up position (V).

NOTE: The output setting applies to all outputs

(humidity, temperature, and setpoint).

2. If selecting voltage, set the jumper:

•Use the top and middle pins for 0-5V.

•Use the bottom and middle pins for 0-10V.

NOTE: If the jumper is missing or removed, the

output voltage will default to

0-10V.

NOTE: The factory default for displayed temperature

units is °F. To change the display to °C, snip the

wire jumper (0 Ohm resistor R64) on the back of

the PCA.

SEN0588R1

Figure 5. Changing Display to °C.

3. Snap the room unit cover to the room unit base plate

by first hooking the room unit front to the top latches,

and then rotating the cover downward until it latches.

4. Loosen the safety set screw at the bottom of the

base one or two revolutions to lock the cover to the

base. Be careful not to loosen too far as the screw

can be completely removed from the base.

Electrical Box and Rough-in

Mounting, Typical

1. If a locator is attached to the rough-in device,

remove the locator by removing the two screws and

lightly rocking the locator to pull it free.

2. Untie the twist tie and pull about three inches (75

mm) of the room unit cable through the hole in the

base plate.

3. Mount the room unit base plate on the wall, noting

the UP arrow:

a. Install the two room unit mounting screws

provided, but do not tighten.

b. Level the room unit base plate for appearance

only.

c. Tighten the two mounting screws to the room

unit base plate.

CAUTION:

Over-tightening may cause the room unit

base plate to crack or bend.

4. Continue with Drywall Mounting (No Rough-in),

Typical, Steps 6 through 8, and Sensor Set-up.

CAUTION:

To prevent equipment damage, do the

following:

If room unit is powered by AC (See Figure

8.):

•AC Supply must be type NEC Class

2 and earth grounded at the

secondary neutral.

•Room Unit ACN (GND) must be

connected to the controller common.

•If the controller has a floating

common, that common must be

connected to the same earth ground

point as the controller AC supply.

If room unit is powered by isolated DC

(See Figure 7):

•Where power is current limited up to

300 mA, it is not required to earth

ground the controller isolated

common.

•Room Unit DC-(GND) must be

connected to the controller common.

CAUTION:

Follow manufacturer’s Installation

Instructions and Wiring Guidelines for

connecting the controller to the Room

Unit.

•APOGEE Controllers with common

already earth grounded are TXIO used

on PXC Modular, PXC Compact 36

Expansion and P1 BIM or PTM used

on MBC and RBC. These do not

require the earth ground wire to be

connected to the controller as shown in

Figure 8.

•APOGEE Controllers with floating

common are PXC Compact 16/24/36,

MEC, PXM, LON TEC and PPM.

These require the earth ground wire to

be connected to the controller as

shown in Figure 8.

* Not available on “SS” models.

NOTE: If active temperature (0-5V/0-10V/4-20 mA)

(Pin 3) rather than passive/resistive temperature

is used, Passive Temp Common (Pin 6) does

not need to be terminated.

The installation is now complete.
