Diagram Selection
Diagrams are provided for both single- and three-phase circuits, and are readily identified in the Selection Table on the following page. The Selection Table enables easy selection of the correct wiring diagram after the electrical components of the unit heater have been determined. The control codes are listed to aid in locating the correct diagram.
Diagram Interchangeability
The 115v/60Hz/1φ diagrams may also be utilized for 230v/60Hz/1φ by substituting 230-volt components in the 115­volt shown.
The 230v/60Hz/3φ diagrams may be modified to 460v/60Hz/3φ by adding a 460v to 230v step down transformer and wiring the unit as shown in the wiring “inset” on all 3-phase wiring diagrams.
The 460v/60Hz/3φ diagrams may be modified to 575v/60Hz/3φ by adding a 575v to 230v transformer and wiring the unit as shown in the wiring “inset” on all 3 phase diagrams.
NOTE:
As indicated in every diagram, all wiring must comply with the national electrical code and all local codes. All components must agree with their respective power source.
To facilitate interpretation and enable simplification the abbreviations and symbols have been selected as recommended by ANSI (American National Standards Institute) and NEMA (National Electrical Manufacturers Association) standards.

WIRING DIAGRAM SELECTION
ii
Wiring Diagram Selection
A. Field and Submittal Wiring Diagram Selection
Wiring in the field changes little when the brand of the controls furnished on the unit heater changes. Select correct wiring diagrams as follows:
1. Determine unit heater model and size.
2. Select control code number from Table 4.
3. Reference unit heater model in the Page Location Index with control code number and determine correct page number for single-phase or three-phase control. Single-phase wiring diagram page numbers are in the upper left of box and three-phase diagrams are in the lower right of box.
4. Wiring diagrams for unit heat accessories are listed in Table 5. Use the accessory diagrams along with the unit wiring diagrams for complete wiring instructions.
B. Service and Troubleshooting
Because internal or factory wiring may vary depending on controls manufacturer, the wiring diagrams must be selected with the series identity number when servicing or troubleshooting unit heater control system. Wiring diagrams in this bulletin are for unit heaters manufactured after April 1995. The series identity number is the 5th through the 7th digits of the unit heater serial number.
EXAMPLE:
Serial no. — 1510101
0495-0098 has a
series identity number of 101.
To select the correct wiring diagram:
1. Determine unit heater model and size from serial plate located on the side of the unit.
2. Determine the control code numbers from box marked
Control Code
, also on the serial plate.
3. Determine the
series identity number
of the unit heater, then proceed with Step 3 of Field and Submittal Wiring Diagram Selection.
Example Selection
Select correct single-phase wiring diagram for a PV 175A Control Code 11, series identity number 101.
Locate the page which shows the wiring diagram number for PV and BV units with series identity number 101 (see page iii). Select the page number where the column for the PV 175 intersects with the line for control code 11. The correct wiring diagram can be found on page 9 as shown in the upper left hand corner of box. If this unit also had a summer/winter switch, the accessory wiring diagram found on page C-1 as per Table 5 would also be required for complete wiring information.
Two-in-One Diagrams
Two wiring diagrams are furnished for each circuit configuration in this manual. Included are a connection diagram at the left for field installation and circuit schematic at the right to aid in continuity and troubleshooting.
The heavier lines in the connection diagram indicate line voltage; the lighter lines indicate low voltage. Solid lines show pre-wiring performed at the factory; dotted lines inform the installer of connections required to put the heater in operation.
