Choose Your Boiler Controller

Need a controller for a new boiler installation? Time for a refresh or upgrade? Here is the easy comparison to help you through Lakewood’s choices for Boiler applications. For boilers, we have three choices: Model 150, Model 1575e, and Nexys controllers. Of course each controller can monitor conductivity and open blowdown per your setpoints. Here are other considerations:

• Output Relays – the number of valves, pumps or other actions the controller can manage.
  • Model 150 – 3 relays.
  • Model 1575e – 4 relays.
  • NexSys – 6 relays upgradeable to 10 relays.
• pH – can the controller also monitor condensate pH?
  • Model 150 – no.
  • Model 1575e – yes.
  • NexSys – yes.
• Water Meters – how many water meters can the controller deal with?
  • Model 150 – one.
  • Model 1575e – two.
  • NexSys – four.
• Display size – what does it show you on its display?
  • Model 150 – two line LCD.
  • Model 1575e – four line LCD.
  • NexSys – color touch screen.
• Sample Hold capability – if your plumbing is prone to steam flash, you can minimize those effects with this sample hold operation.
  • Model 150 – Yes!
  • Model 1575e – no.
  • NexSys – no.
• Connectivity – what info can the controller share with others?
  • Model 150 – conductivity via 4-20 mA analog output
  • Model 1575e – conductivity via 4-20 mA analog output
  • NexSys – all system parameters including graphs, via EZWeb Wireless or BMS integration.
