Find the Right Manual for Your Honeywell Control: use your browser's built-in search feature such as CTRL-F to search for a keyword (eg. aquastat) or to search for a key model number (eg. CT3200) to find the manual for your Honeywell device on this page.
The Honeywell control free PDF downloads given on this page are listed alphabetically by control name or number. We include at least one photo or image of each control to help you identify these HVAC controls, but
Watch out: there are so many Resideo/Honeywell HVAC controls that it's easy to mix up control names or numbers, so double-check the data tag on your control or check the control part number described in the installation manual for your equipment.
Honeywell TRADELINE CONTROLS CROSS REFERENCE [PDF] This is a cross reference giving direct or functional replacements for abouty 75,000 old and new Honeywell OEM and competitive controls.
Describes control circuits, thermostats, limit controls on air, hot water & steam heating systems, low water cutoffs, oil burner controls, gas burner controls, solenoid valves, motorized gas valves, LP gas controls, and transformers.
Below we list Honeywell controls and manuals and articles alphabetically by the control type or actual control name or number.
STRAP-ON LIMIT CONTROL [Web article] Uses & safety warnings about strap-on type boiler limit controls -
Honeywell L4006, Manual Reset Strap-On Aquastat (high limit control, 100 to 240 °F)
Watch out: we consider strap on controls an out-dated safety device that is less accurate and reliable than immersion type sensor controls;
Strap-on aquastats were commonly found on older heating boilers including the GE series downfired boilers

Honeywell L4026B Aquastat control instructions (contact Honeywell Corporation) Some basic description of the Honeywell L4026B control, also available at www.honeywell.com
The L4029E Reset Limit Control opens a line or low voltage circuit if the air temperature reaches a critical level at a controller location. The primary usage of the L4029E is as a fire thermostat in the duct work of air conditioning and ventilating systems.
If the circulated air reaches a temperature indicative of a fire, the limit control shuts off the fan, preventing the fan from contributing to the spread of fire. It is also suitable for use with any warm air furnace to provide positive lockout of the burner in the event of a fan failure.
HONEYWELL L6006 AND L6007 AQUASTAT CONTROLLERS, [PDF] installation instructions for the trained service technician, these controls combine low or high limit and circulator control, with or without an immersion well depending on the control model A,B, C etc., also available at www.honeywell.com
HONEYWELL L6064 UNIVERSAL TWO SPEED FAN & LIMIT CONTROL MANUAL [PDF] A liquid filled aquastat with two SPDT switches for horizontal or vertical mounting. Breaks on temperature rise. With two single conduit boxes. Quick connect terminals with jumper between controller and limiter. With smaller diameter sensor.
HONEYWELL L7224 AQUASTAT CONTROLLER, oil electronic controls allowing high limit, high limit differential, low limit, and separate low limit differential settings - set to the specifications of your oil heating equipment manufacturer - 69-1957-1 L7224 Series controls, also available at www.honeywell.com
HONEYWELL L7224U OIL ELECTRONIC AQUASTAT CONTROLLER - 69-1720-2 series instructions. These newer"Universal" aquastat controllers are often used to replace the older Honeywell L8124A series that was and remains widely used, also available at www.honeywell.com.
L7224U1002- is a universal electronic aquastat (replacing over 40 other aquastat models) that provides circulator, burner and boiler temperature control with electronic temperature sensing. The L7224U1002 provides status and diagnostic information through an LED display to enhance the diagnostic process.
In "Run" mode the LED displays the boiler temperature followed by the ambient temperature. Buttons inside the control permit the service tech to scan through the control's settings as well as to change them, much like the functions on a programmable room thermostat.
Using the "I" button, the LED display can be cycled through: boiler temperature, high limit, low limit, high differential, low differential, local thermostat status, EnviraCOM thermostat status, Burner status, Circulator status, Zone control, Zone request, Error code, °F/degC.
Five diagnostic LEDs inside the control provide additional diagnostic features, indicating (counterclockwise from upper left) EnviraCOM network active, Thermostat calling for heat, Burner on, Power to zone circulator interrupted (lockout), Circulator powered.
This is a "triple aquastat" providing High, Low, and circulator controls, as well as advanced features permitting electronic configuration and an LED display for diagnostics. This aquastat can provide multiple zone control as well.
The L7224U1002 supports Honeywell's EnviraCOM™ communications that permits remote diagnosis as well as OnWatch diagnostics. The low-limit can be disabled for "cold-start" boiler applications such as where no tankless coil is in use.
Eight error codes:
1=sensor fault (check sensor),
2=ECOM fault, check EnviraCOM wiring,
3=Hardware fault, replace the control,
4=B1 fault, check B1 wiring/voltage,
5=Low line voltage, check L1/L2 110VAC,
6=Fuse, check ECOM wires, replace fuse,
7=EEPROM limit and differential settings, restore to desired settings,
8=Repeated B1 fault, (voltage present at B1 when output is turned off); check B1 wiring/voltage
