of data may occur if the

user does not follow

procedure as specified.

Required Tools

 Electro-Static Discharge (ESD) wrist strap

 Small flat-blade screwdriver

 Medium flat-blade screwdriver

 Medium-duty electric drill

 1/4-inch (6.35 mm) hex nut bit

 Portable Operator’s Terminal with Controller

Interface Software (CIS) Rev. 2.0 or higher

(controller replacement only)

Additional tools needed if not using self-tapping option:

 1/4-inch (6.35 mm) hex nut driver

 1/8-inch (3 mm) bit

Prerequisites

 Room temperature sensor installed (optional)

 Air velocity sensors installed in ducts

 24 Vac Class 2 power source

 Supply power to the unit is OFF

 Autozero Modules with brackets are on hand

(optional)

 If required, controller enclosure installed

Expected Installation Time

New controller installation

10 min.

Replacement with removable

terminal blocks

6 min.

Replacement without removable

terminal blocks

16 min.

NOTE: You may require additional time for

database work at the field panel.

New Installation Instructions

NOTE: For Autozero Module installation, refer to

Installation Instructions (540-199).

1. Using the mounting rail as a template (See

Figures 1 and 2), mark the location for the two

screw holes where you will install the controller

assembly.

2. Do one of the following:

 If using the self-tapping screws: Using

the drill and the hex nut bit, fasten the

mounting rail. (Screws do not require starter

holes.)

 If not using the self-tapping screws: Drill

two 1/8-inch (3 mm) pilot holes. Align the

mounting rail with the holes. Using the hex

nut driver, fasten the mounting rail with the

No. 6 or No. 8 screws.

Connect the tubing from the air velocity sensor pickups to the HI and LO ports on the controller, or on the Autozero Modules (if present). Make sure that the “HI” and the “LO” pressure sides of the sensors are connected to the “HI” and “LO” sensor ports on the controller (See Figure 1) or Autozero Modules (See Figure 2). See Table 2 for air velocity sensor connections. b.

Do one of the following:  If you updated the initial values from the old controller at the field panel, then when you set the address and application for the new controller, the field panel will automatically send the initial values down to the new controller. Once this takes place, replacement is complete.  If you manually recorded the initial values in the table, then enter them into the new controller.

Document Number 540-1033 Installation Instructions October 26, 2016 NOTE: Refer to the unit wiring diagrams or consult with the local representative if terminations are missing or are different. NOTE: When wiring any actuator that uses a 0 to 10V control signal and ties AC neutral to DC common, an additional wire must connect the actuator AC neutral to the DC common of the PTEC/TEC AO being used to control the actuator.
