TG-VI, MT µP-IV, µP-V, µP-VI, SR-2 or SR-3 Controller
The microprocessor uses relays to operate unit valves and solenoids. Each relay circuit is fuse protected. The relay board also
contains the CYCLE-SENTRY buzzer, remote light fuses, ammeter shunt and jumpers to configure the relay board for proper
operation.
NOTE: Refer to the appropriate Controller Operation and Diagnosis Manual for more specific relay board information for
your unit.
