Page 3: Introduction
Consult representative for more details. Description of Unit MegaTronMT controllers can control single or multiple recirculating water systems, including cooling tower and boiler applications, and may have various features depending on the model number. -
Page 4: Installation
Chemical Feed Timers Chemical feed timers are designed to automate the addition of various chemicals by activating a relay output. Multiple timers can be supplied depending upon the model number and each timer will include a relay output. All timers can be programmed to be one of the following types. Pulse Time - Accepts pulses from a make-up water meter (supplied separately). -
