Boiler water controller, designed to measure the hot boiler water conductivity (sensor SR2) and open or close a motorized ball valve, that will drain water from the boiler. The automatic control of water allows the boiler to operate at safe levels of water concentration with the minimum amount of energy loses. Read article for more details.
The sensor works up to 600 psi and 486 Deg F. Orifice plate needed to assure the integrity of the sensor. Below the available kits
Part Number 1229245 is Automated Kit for 3/4" pipes - Includes 1575e Controller, SR2 Sensor, 3/4" Union, Orifice plate.

FEATURES
• Removable power cord and receptacles for simple conduit installations.
• Scheduled feed, which can use three relays for biocides or other chemicals.
• Two (2) water meter inputs, two (2) drum switch inputs, conductivity input, flow switch input, 4-20 mA output,
and remote conductivity input via 4-20 mA are all standard features.
• Designed with a single circuit board for better reliability and lower cost.
• Large open shallow enclosure for easy wiring.
• Ball valve delay feature allows accurate control of motorized ball valves.
• Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy
programming. Steel domed switches improve the tactile sensing and life expectancy of the keypad.
• LED indicators for power, alarm and relay status.
BENEFITS
Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
• Controller can be used in boiler, cooling tower, or condensate applications when used with the appropriate
conductivity sensor.
• Single circuit board design improves reliability.
• No add-on options. 4-20 mA output and feed schedule clock features are standard.
