Oil Electronic
Aquastat® Controllers
APPLICATION
The L7224A,C and L7248A,C,L 2012 Compliant Oil
Electronic Aquastat® Controllers provide electronic
temperature sensing in a UL limit-rated control with a
single sensing probe. The L7224A,C and L7248A,C,L
control the circulator, oil burner and boiler temperature.
The L7224/L7248 is “Outdoor Temperature Reset” ready
which is enabled when connected to the W8735S1000
Outdoor Reset Kit. Outdoor Reset with the L7224/L7248
is intended for all applications except for tankless coil
systems for domestic hot water. Compliance to 2012
DOE regulation ensures efficiency is maximized without
interfering with domestic hot water demand.
The L7224A,C and L7248A,C,L replace the L8124A,
L8124C, L7124A,C, L7148A and L8148A Control ers.
The L7224A,C and L7248A,C,L series controls provide
status and diagnostic information through an LED display
combined with LED lights as well as EnviraCOM™
communications enabled thermostats and diagnostic
tools to enhance the diagnostic process.
L7224/L7248 Aquastat Controllers are intended for use
in residential-type applications.
IMPORTANT
Use of Outdoor Temperature Reset on a tank-
less coil application requiring a Low Limit setting
will result in reduced system effectiveness and
efficiency.
