1.5 Example Site Layout

SECTION 1: INTRODUCTION

-OR-

CORAYVAC® systems designed shall have recommended radiant pipe length and 1.2 - 1.5 feet per flow unit of tailpipe length. See the CORAYVAC® Design Manual (P/N 127500NA) for minimum and recommended radiant pipe length.

1.5 Example Site Layout

Page 15, Figure 6 is an example layout for a building where ROBERTS GORDON® ULTRAVAC™ will be used to control the infrared heating systems shown. The layout consists of three zones of ROBERTS GORDON® ULTRAVAC™.

1.6Check Installation Materials 1.6.1 Switchable Loads

The controller relays are rated for switching loads no greater than 3 A. The total added current load for all 8 relays must not exceed 25 A.

1.6.2 Control Wiring

Shielded cable (four twisted pairs of stranded 24 AWG minimum wire) is required for use with indoor sensors.

Shielded cable (one twisted pair of stranded 22 AWG minimum wire) is required for the outdoor air sensor, VFD signal wiring, pressure switch and wiring from controller #1 to the PC.

Shielded cable (one twisted pair of stranded 22 AWG minimum wire) is required for RS-485 communications between controllers.

1.6.3 Control Board and Sensor Power

The power supply for all sensors is from the “+32 V” terminal to be found on the board of the controller. Power for the control board is 24 V provided by the relay board.

1.6.4 Programming Details

Every controller is pre-programmed for one pump and up to three heating zones. Use a site layout drawing to identify the heating zones.

1.7 Safety Labels and Their Placement

Product safety signs or labels should be replaced by the product user when they are no longer legible. Please contact Roberts-Gordon LLC or your ROB-
