The pool lights are a problem. I have two lights. Both come on for a few seconds, then one goes off completely while the second starts blinking like a strobe light.
Possibly a problem with the driver chips.
Unplug the lights from the Aux Relays.
4.1.1 Driver Chips
The driver chips can be thought of as a series of small relays.
When one of the driver chips receives a signal, it closes a contact which passes 24 to 32 VDC to the appropriate relay coil socket, in this case AUX 1.
Each relay driver chip activates a specific set of relay coil sockets (see the chart below). If a driver chip fails, it is usually caused by either shorted relay coil wires, a shorted relay coil, or a relay not designed for the 24 VDC coil voltage (i.e., 24 VAC rather
than 24 VDC).
The relay coil provides resistance (approximately 300 Ohms); if there is no resistance, the driver chip circuit will be damaged.
The driver chips (U6) drive the relays.
They are in a socket, to simplify replacement in case of damage.

5.4 3 HP Relay.
5.4.1 Operation
1. A standard 3 HP Relay's coil is supplied with 24 VDC from the power center PCB via one (1) of the driver chips.
When 24 VDC is received by the relay's coil wires, it closes the contacts that complete the circuit to turn on the equipment (i.e., power supplied to Line 1 goes out Load 1 to the equipment).
2. Standard 3 HP Relays may be wired to activate a 120 VAC circuit (i.e. Line 1/Load 1) or a 240 VAC circuit (i.e. Line 1/Load 1 and Line 2/Load 2).
Note If a relay's coil wires are shortened, or an AC relay coil is plugged into a relay socket, when that circuit is activated, it will
damage one of the relay driver chips on the power center PCB.
