Standard Features
- Boiler or Condensate Conductivity input
- Single water meter input
- Boiler status input
- Chemical feed relay
- 5 Key universal keypad
- 2 Line, 16 character backlit display
- Boiler blowdown or condensate diverter relay (solenoid valve or motorized ball valve)
Benefits
- Selectable chemical feed mode: Provides 3 feed modes; feed on volume, blowdown & feed and percentage time.
- Conductivity control: Can be programmed using timed or continuous sampling.
- Water meter input: Allows for chemical to be fed based on water volume versus timed pump control methods generally found on comparably priced controllers.
- What and Why Information: Diagnostics shown on display are a valuable troubleshooting tool. Conductivity valve and chemical pump relays show complete stauts. Shows WHY the relay is on/off.
- Single point calibration: For ease of start up and operation. Warning message immediately detects foulled or faulty sensors.
- Controller run time: Gives total hours per day and total operating days since initial installation.
- Robust diagnostics: Provides complete 24 hour history of blowdown valve operation and chemical relay timing intervals.
- Keypad password: Eliminates unauthorized adjustments.
- Communication options: Includes Ethernet networking, dry contact alarm relay or 4-20mA output on conductivity.
- Optional web browser user interface with networking capability: Provides ability to direct connect to the controller from a portable workstation, such as a laptop computer. Can also view critical processes remotely through the use of a LAN.
