4. Electrical Wiring

The Pro Logic Control Center requires both high and low voltage connections. Low voltage connections will be made

to actuators, sensors, remote keypad, etc. High voltage connections will be made to pumps, lights, etc., as well as

providing direct input power to the Control Center. Always:

-Ensure that Power is disconnected prior to doing any wiring

-Follow all local and NEC (CEC if applicable) codes

-Use copper conductors only

Main Service (Power to the Circuit Breaker Subpanel)

The Pro Logic circuit breaker subpanel is rated for 100A service. Run properly rated conductors (L1, L2, N, and

ground) from the primary house electrical panel to the main power connections on the Pro Logic circuit breaker base.

The connection at the main house panel should be to a 240VAC circuit breaker rated at 100A maximum.

Grounding and Bonding

Connect a ground wire from the primary electrical panel to the Pro Logic ground bus bar. Also ground each piece of

high voltage (120 or 240VAC) equipment that is connected to the Pro Logic control relays or circuit breakers. The

Pro Logic should also be connected to the pool bonding system by an 8AWG (6AWG for Canada) wire. A lug for

bonding (2 for Canada) is provided on the outside/bottom of the Pro Logic enclosure.

Circuit Breaker Installation and Wiring

Circuit breakers are to be supplied by the installer. Refer to the circuit breaker chart below for a list of suitable circuit

breakers that can be used. Follow the code and the circuit breaker manufacturer’s rating requirements regarding the

size and temperature rating for wiring. Note that some pool equipment may be required to be connected to ground

fault circuit breakers—check local and NEC (CEC) codes.

Pool/Spa Setup

If “Pool Only” or “Spa Only” are selected, then the pool/spa valves are not needed and pushing the POOL/
SPA button on the display/keypad will have no effect. If “Pool and Spa” is selected, then the pool/spa
suction and return valve actuators should be connected to the Pro Logic. Pressing the POOL/SPA button
on the display/keypad will allow the homeowner to alternate between pool and spa operation.

Spa CountDn

This menu will appear only if Pool/Spa Setup is set to “Pool and Spa”. This setting is the time, after you
manually switch the Pool/Spa valves to “Spa Only”, until the Pro Logic automatically returns the valves to
their previous positions. It is programmed in increments of 5 minutes, from “Manual On/Off” (0 minutes) to
“21:00” (21 hours). The filter is forced on during this time period.

Spa Spillover

When spa spillover is “Enabled” and “Pool and Spa”, the homeowner will be able to rotate through “Pool
Only” (both suction and return valves switched to pool), “Spa Only” (both suction and return valves
switched to spa) and “Spillover” (suction valve switched to pool and return valve switched to spa) by
successive presses of the “Pool/Spa button.

Filter Operation

If “Spa Spillover” is selected, the Pro Logic will automatically switch the pool/spa suction and return
valves to “spillover” at the start of the programmed pool filtering time period or when the super-chlorinate
function is turned on. The valves will remain in this position for the remainder of the super-chlorinate
period. This option is usually preferable because both the pool and spa water will be filtered and sanitized.

If “Pool Only” is selected, then the Pro Logic will switch the pool/spa valves to the “pool only” position
at the start of the programmed pool filtering time period or when the super-chlorinate function is turned on.
This may be desirable on some systems with in-floor cleaners because it allows the cleaner to operate all
the time the pool is being filtered and/or the super chlorinate is running.

V1=Aux1, V2=Aux2

This menu appears only if the Pool/Spa Setup is “Pool Only” or “Spa Only”. When enabled, Valve 1
(return) will follow the Aux1 output and Valve 2 (suction) will follow the Aux2 output. When disabled
(default), the return and suction pool/spa valves function normally.

Filter Off Valve Change

This menu appears only if Pool/Spa setup is set to “Pool and Spa - Std”. When enabled (default), the filter
pump will shut off for 35 seconds whenever the Pool/Spa valves are turning. The pump will NOT shut off
when a heater is in Heater Cooldown mode.
