Optional Remote Key Pad Control Wiring Instructions
for ”Digital Logic” Digital Control Models with Time Clock Override Option Only
The AT800, AT600, & AT400 with “Digital Logic” digital control models having the External
Optional Time Clock Override feature can be retrofitted with our simple, “Remote Key Pad” con-
trol. This Remote Key Pad is identical to the key pad on the heater.
The heater must have the
time clock override option to use the remote key pad !
The Remote Key Pad will perform
the all the same functions as the heater’s key pad: Heater on/off. Pool temperature readout.
Thermostat settings for pool & spa. Activation of two field installed Jandy™ 2440 actuator
motors via pool/spa select buttons. NOTE: The water pump can be activated via the time clock
override button. When spa mode is selected, the water pump will start and stay running con-
stantly while in spa mode. When in pool mode, the time clock override will only run the water
pump when the thermostat calls for heat.
Installation of the Remote Key Pad is as follows: First, the time clock override feature must be
wired to the heater as shown on pages 11 - 13. Next, mount the Remote Key Pad a maximum of
150 feet from the heater in a dry location at least 6 feet away from the pool/spa water. The
Remote Key Pad is not water resistant and therefore must be kept dry ! Next, remove the 3/4”
threaded cap on the low voltage conduit port. To prevent water penetration, attach a 3/4” M.A.,
90 degree compression type fitting and a minimum 6” of flex conduit to the 3/4” female adaptor
on the top right hand side of the heater. Make sure it is pointing it downward. Use epoxy sealer
to seal the conduit. Next, run a 4 wire, #18 gage (minimum wire size) insulated cable from the
Remote Key Pad through this conduit. Attach the Remote Key Pad wires to the heater’s solid state
circuit board as shown on page 15.
WARNING:
Improper connection of the Remote Key
Pad wires will short out the control system BE SURE THIS IS DONE CORRECTLY !!!
Assuming the plumbing is similar to the schematics on page 6 and Jandy brand 3-way valves are
in place, you can install two Jandy actuator valve motors. Install one on the suction valve and one
on the return valve. Label the piping on either side of the motor valves (pool or spa) so the valve
position can be identified by the user. The actuator motor wires should ran through the same
conduit and should be installed (plugged into) the heater’s solid state circuit board as shown on
page 15.
You do not have to have the remote key pad to install Jandy actuator motors.

TIME DELAYS
30 second compressor
delay when switching
pool/spa modes.
5 minute compressor
delay when T.C.O. en-
ables in pool mode.
5 minute T.C.O. off de-
lay when: switching
from spa to pool mode,
when temperature is
reached in pool mode,
or if LF (low water flow)
is displayed on LED.
If water pump loses
prime while motor
valves are rotating there
will be a 3 minute com-
pressor delay.
