Variable-Speed Pumps
®
3.5.5
Aqualink TCX
Aqualink TCX supports a single variable-speed pump.
Dip Switches 3-4 must always be set in the OFF position
when the pump is connected to a TCX Automation
System. This is true even when connected to a TCX
system using the automation pass-through wiring on a
Jandy SpeedSet controller.
3.5.6
All Other Jandy Automation Systems
All other Jandy automation systems support up to 4
variable-speed pumps utilizing Dip Switches 3-4 in the
same manner as defined in section 3.5.3.
3.6
Auxiliary Relay Operation
Pumps models in this manual are equipped with a
terminal bar that provides user access to two built-
in Auxiliary Relays. The normally-open relays are
activated under certain operating conditions and are
intended to be used to control external devices that
require system water flow for proper functioning, such as
booster pumps, salt water chlorinators, etc.
See Figures 12-13 for compartment details and location
of the auxiliary relays and wiring illustrations.
Auxiliary Load Connection Requirements
ELECTRICAL SHOCK HAZARD
Due to the potential risk of fire, electric shock, or injuries
to persons, Jandy
Pumps and any auxiliary loads must
®
be installed in accordance with the National Electrical
Code
(NEC
), all local electrical and safety codes, and
®
®
the Occupational Safety and Health Act (OSHA). Copies
of the NEC may be ordered from the National Protection
Association, 1 Batterymarch Park, Quincy, MA 02169, or
from your local government inspection agency.
In Canada, Jandy Pumps must be installed in accordance
with the Canadian Electrical Code (CEC).
• The Auxiliary Load relay contacts are rated at
230V/115V, 11A RMS. Please ensure the requirements
of the equipment to be connected to the Auxiliary Load
do not exceed this rating.
3.6.1
Auxiliary Relay Operation
Auxiliary Relay contact activation is speed dependent.
Auxiliary Relay 1 has an activation speed of 1725 RPM
and Auxiliary Relay 2 has an activation speed of 2250
RPM.
The Jandy SpeedSet controller provides the ability
to reprogram the Auxiliary Relay open/close speeds
for customization. Open/close speed settings that are
changed using this feature are permanent even if the
SpeedSet controller is disconnected.
Please refer to the "Settings" section in the Jandy
SpeedSet controller I/O manual for additional details.
3.6.2
Contact Closure
From a stopped condition, there is a three-minute delay
before the Auxiliary Relay contact is closed when the
motor speed reaches and maintains the activation speed.

Installation & Operation Manual
WARNING
ENGLISH
Once the three minute run time criteria has been reached,
when going from an RPM below the activation speed to
an RPM above the activation speed, there is a 5-second
delay before the Auxiliary Relay contact is closed.
3.6.3
Contact Opening
When going from an RPM above the activation speed to
an RPM below the activation speed, the relay opening is
always immediate.
Section 4. Dry Contact Operation
External relays or switches can be used with the dry
contacts if a Zodiac controller is not connected to the
RS-485 line. By creating a circuit that runs between the
dry contact, the external switch/relay, and the common
on the dry contact, when the circuit is closed the pump
will turn on, prime at 2750 RPM for 3 minutes, and go to
the pre-determined speed of the dry contact indefinitely
until the circuit is opened by the external relay.
If no inputs are jumped to common, the RPM is zero.
When any Zodiac controller is connected through
RS-485, all dry contact commands will be ignored. Refer
to Figures 12 and 13 for dry contact wiring. Refer to
table 5 for dry contact speed settings.

Dry Contact Speed Settings
Dry contact speed settings were adjusted with motor
serial numbers beginning with the letter B.
