WARNING
ELECTRICAL SHOCK HAZARD
Due to the potential risk of fire, electric shock, or
injuries to persons, Zodiac
®
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, Zodiac 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
.
3.5.1
Auxiliary Relay Operation
Characteristics
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.
3.5.2
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.
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.
3.5.3
Contact Opening
When going from an RPM above the activation speed to
an RPM below the activation speed, the relay opening is
always immediate.
3.5.4
Dry Contact Operation
Dry contacts can be used as a controller if a Zodiac
controller is not connected to the RS-485 line. By
jumping one of the inputs to common, it will turn on
the pump, prime, and go to a pre-determined speed
indefinitely until the short is broken (See Figure 10 &
11). If no inputs are jumped to common, the RPM is
zero. These speed settings cannot be changed unless
a Zodiac controller is connected. When any Zodiac
controller is connected through RS-485, all dry contact
commands will be ignored.

3.4 Pump DIP Switch Settings
The motor is equipped with an auto sensing power
circuit which illiminates the need for DIP switches
1 and 2. As shown in Figures 9, the 2-position DIP
switch serves the function of pump addressing when
using multiple pumps. If the pump is connected to a
JEP-R controller or iQpump01, DIP switches 3 and 4
must remain in the OFF position. If connecting to an
automation system that supports multiple pumps, use
the DIP switches (See Table 3) to set the address for the
pump and refer to the automation system's manual for
additional instructions.
NOTE
DIP switches 3 and 4 must only be used if your
Zodiac
®
Automation system does NOT have RS-485
auto-addressing capabilities.

3.5 Auxiliary Relay Operation
Jandy pump model numbers ending with "2A" 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 10 and 11 for compartment’s location
details.
