LED DIAGNOSTIC LIGHTS
(106-6669 INTERFACE BOARD)
CMP Indicates power from 12V transformer.
24V
Indicates power from 24V transformer.
HI
Indicates output (closed) from latch relay (K4).
HT
Indicates output from heat relay (K3).
AL
Indicates output (open) from latch relay (K4).
The board contains four relays. K3 is the heat relay and K4 is the latch relay. K1 and K2 are only
used in "dual" or "split" pot applications.
