CuproNickel

Cupronickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Cupronickel is highly resistant to corrosion in salt water, because its electrode potential is adjusted to be neutral with regard to salt water. Because of this, it is an ideal choice for swimming pools using salt chlorine generators.

LRZE (Electronic)

  • Digital control of pool and spa set-points
  • Self diagnostics and communication to Jandy AquaLink® RS Systems
  • Polymer headers with CPVC 2/2.5" universal union connections

LRZM (Millivolt)

  • Easy on/off temperature switch control
  • Mechanical thermostat allows users to easily set pool or spa temperatures
  • Polymer headers with CPVC 2/2.5" universal union connections

The Pool Sizing Guide shows the maximum pool surface area our Legacy models will heat based on the temperature difference between the air temperature during the coldest month the pool is used and the desired pool temperature. Figures are based on average wind conditions and average pool depth.

The Spa Sizing Guide details the time required for each model to raise spa temperature by 30°F.

Will a gas heater operate at the low speed of a dual speed motor?
 Reply

A  Answered on 1/16/2012 by InyoPools Product Specialist Patrick P.

Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.

What is the difference between an Electronic and Millivolt ignition?
 Reply

A  Answered on 10/10/2012 by InyoPools Product Specialist Patrick P.

The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.
