NOTES:

1. If any of the original wire furnished must be replaced, it must be replaced with type 90° C or its equivalent.

2. Three phase motors are protected under primary single phasing conditions.

3. Use copper conductors only.

4. RED jumper wire must be added between R and Wl for Space Temperature mode and temporarily during Ser-

vice Test mode when the heaters need to operate.

5. TRAM1 and 2 are wired for 230 v on 208/230 v units. If unit is to be run with 208 v power supply, disconnect BLK

wire fR)m 230 v terminal and connect to 200 v terminal.
