Chiltrix CX50 - Connecting a Second Non-PWM Water Pump; Wiring and Relay Requirements

When using a second NON-PWM water pump
When using a second NON-PWM water pump, use terminals L2 and C6L for relay coil
power only. Do not connect a pump directly to L2 and C6L, always use a relay with a 240
vac coil. This pump will only run when the PWM pump is running. Setting P52=0, and
P54=1, will shut C6 off when the chiller reaches its set point.
