PW-DMTD : 2 Pool PoolWarden pool controller system pre-mounted Swimming pool chemical automation refers to the automatic monitoring and control of the sanitizer and pH levels in water, in order to maintain clean, safe water at all times, while achieving significant reductions in the cost of chemicals, maintenance and repairs. Automation is now recognized as a necessity for all commercial and public pools and spas, as well as for quality residential installations. ControlOMatic systems offer the most advanced line of electronic controllers for monitoring and control of water chemistry. The PoolWarden is a water chemistry control system designed to control the pH, sanitizer and temperature on up to two bodies of water at the same time. Using ORP (oxidation reduction potential) technology, the control of sanitizer takes into account the effects of pH. A pH lockout feature is also included for high pH values. 4 Relays are included for each pool: A pH and ORP relay supplying the input voltage and two additional auxiliary dry contact relays can be used to control a heater and a backup sanitizer when the primary sanitizer is a salt system. Water measurements are taken continuously while PoolWarden's internal relay program determines if chemical adjustments are needed. Energy management is supported by providing two setpoints per day for heater control. OPTIONAL Accessories: When ordering, we will contact you to see if you want to add any of the following options: - PW-Lan: Ethernet communication - PW-Pigtail: Short extension cords that bring the relay connections outside the box - TrueDPD: Add colorimetric DPD free chlorine sensor and control on PPM, ORP or both. This option may make the PoolWarden California TITLE 22 compliant (allows for taking readings from the PoolWarden to add to the log books on days the water wasn't manually measured).
