Figure 1. Room Pressurization Controller – Pneumatic Output without Autozero Modules.

3. Mount the enclosure on the screws and tighten

them down with either the drill or hex nut driver.

4. Remove the appropriate knockouts.

5. Place the ESD wrist strap on your wrist and

attach it to a good earth ground.

6. Connect the Local Area Network (LAN) trunk

(Figure 4). Run the wiring through knockout.

CAUTION:

Do not connect an earth ground to

the Shield (S) terminal.

7. Connect the point wiring for the appropriate

application. See Figure 7. See Table 1 for

application descriptions. Run the wiring through

knockout.

CAUTION:

The Controller's Digital Outputs (DOs)

control 24 Vac loads only. The

maximum rating is 12 VA for each DO.

For higher VA requirements, 110 or

220 Vac requirements, separate

transformers used to power the load,

or DC power requirements, use an

interposing 220 V 4-relay module

(TEC Relay Module P/N 540-147).

NOTE: Each DO provides a Normally Open

(NO) and a Common (C) terminal. Terminate

both connections of a 24 Vac load directly to the

controller board.

NOTE: The 24 Vac "H" terminal is switched

through a TRIAC to the NO terminations when

the associated DO is energized.

8. If using a pressure mode switch, then follow the

Room Pressurization Controller (RPC) Pressue

Mode Switch nstallation Instructions (540-719)

included with the switch.

9. After the pressure mode switch is installed, wire

the switch to DO8 and AI3 as described in the

instructions.

10. Plug the Room Temperature Sensor cable into

the RTS port on the controller board. See

Figure 1. Run the cable through knockout.

11. Connect the power trunk as shown in Figure 5.

DO NOT apply power to the controller. Run the

wiring through knockout.

12. Replace the enclosure cover and tighten the

cover screws.
