Robertshaw Uni-Kit 780-001 Installation Data

Robertshaw® Universal Ignition Control Uni-Kit
nonlockout (780-001) and lockout (780-002). The 780-003 is lockout
with a prepurge function.
The Universal Ignition Control Uni-Kits feature a flame sense circuit
that automatically detects the presence of a remote sense probe (2
rod system) or it switches to local sense (1 rod system) utilizing the
pilot assembly as a sensing source. If both systems are provided,
failure of one causes automatic reversion to the other.
780-001 (NONLOCKOUT)
The automatic recycle features assure that, in the event of flame
failure, main gas is disabled and the spark repetition sequence is
restarted until pilot gas is ignited. Only after pilot ignition has been
reestablished can main gas be returned to the burner.
780-002 (LOCKOUT)
These kits have a lockout feature to shut off all gas to the furnace,
should pilot ignition fail to occur after a predetermined time period.
The 780-002 provides 3 tries for ignition. Each ignition period is 60
seconds followed by a 5 minute time delay between ignition attempts.
After 3 tries if no pilot flame is sensed, unit goes into lockout and must
be reset at the thermostat.
780-003 (LOCKOUT w/prepUrge)
Same features as the 780-002 above, except it has a 45 second
prepurge function.
