From Lakewood Instruments

Lakewood Model 2855e Multi-Boiler Controller

2855eThe Lakewood Model 2855e Multi-Boiler Controller uses LonWorks® Technology for accurate control of your boiler system. The system will allow control of one to eight boilers using the cycle sample or continuous sample method. Two water meter inputs are available which can be used to feed chemicals. Each conductivity input contains its own microcontroller which talks directly to the relay that controls the motorized ball valve for each boiler. The 2855e can be programmed with LRWS (Lakewood Remote Windows Software) or from the keypad of the controller. LRWS allows data to be accumulated on all boilers, water meter inputs, chemical pump on time and more.


  • Cycle/Sample or Continuous sample control of blowdown, configurable in the field.

  • Two water meter inputs, conductivity input with 20 ft cable, flow switch input, four relay outputs, and Power On/Off switch in a NEMA 4X enclosure are all standard features.

  • Removable power cord and receptacles for simple conduit installations.

  • Includes four relays for blowdown, chemical feed, and alarms; expandable up to 12 relay outputs.

  • Includes three security levels to prevent unauthorized programming access.

  • Includes two languages; English/Spanish are standard.

  • Heavy-duty stainless steel domed numeric keypad and large illuminated graphical display allow for quick and easy programming.  Steel domed switches improve the tactile sensing and life expectancy of the keypad.


  • Accurate control of boiler conductivity.

  • Control results in fuel savings by preventing excessive blowdown.

  • Prevents carryover due to excessive conductivity.

  • One controller can monitor and datalog up to 8 Boilers.
