The System 3NX pool and spa controller is a low-cost, high-specification controller combining the ease of use required for day-to-day operation with the features demanded for today’s pools. Stranco® products High Resolution Redox® sensors are utilised
for the System 3NX controller to give a derived PPM pool reading as a bar graph display. The pH, redox and temperature are shown on the alphanumeric
display.
The System 3NX controller provides user-defined high and low level alarms, overfeed protection, an alarm output relay and proportional control. For spas, the remote alarm relay may be reprogrammed to be used for pH up control, converting the controller
to pH up and down operation. The controller and flow cell, complete with electrical junction box and flow switch is offered as an option, pre-mounted on a uPVC board for ease of installation and routine servicing.
Strantrol® Sensors
Patented technology Strantrol® sensors - guaranteed for 2 years - can be expected to last over 5 years in most pools.
Should any control readings fall out of range, failsafe networks with independent feed lockouts provide an extra measure of safety.
Benefits
• Proportional Feed: ensuring a rapid response to changing bathing loads so the water is of consistant quality.
• Overfeed: peace of mind that bathers are protected from chemical overfeed, to user defined parameters.
• Full Display and Alarms: alphanumeric display of pH, redox and temperature alarms and access menus. LED display PPM at a glance with end of range alarm LED’s.
• Temperature: on the standard arrangement,
the System 3NX controller is fitted with a PT100 temperature sensor, temperature
display and high and low temperature alarm set points as standard.
• Warranty: two year warranty on controller and probes.
