R7284B,P,U,G ELECTRONIC OIL PRIMARY, ENVIRACOM™ ENABLED
Lockout Modes
The R7284 has three types of lockout modes that are
entered when an error is encountered:
• Soft Lockout: Caused by a temporary internal error
such as low voltage. The control recovers
automatically after the error is no longer detected.
• Hard Lockout: Caused by a failure internal to the
control or by a system fault such as flame out of
sequence. A Hard Lockout will result in a no heat
condition. To reset from Hard Lockout press and
hold the "i" button for 2 seconds.
• Restricted Lockout: Caused by a number of
consecutive hard lockouts on the same heat cycle.
To reset from a Restricted Lockout press and hold
the "i" button for ten seconds.
Valve-on Delays/Blower Motor-
off Delays
Select models may have fixed or adjustable delays for
valve open or blower motor off. The safety circuits will
check for flame during these delays and, if a flame is
present, will switch the control to lockout.
