Connection To A Secondary User Interface - Jandy JRT Serie Manuel D'installation

Jandy ® JRT Series Heat Pumps
6. The wires coming from the Jandy JE heat pump
can be "doubled up" on the red terminal bar
with the four (4) wires coming from the indoor
controller.
NOTE If you need to install more than two (2) wires in
each terminal, order a Jandy
Kit, which includes the Multiplex Board (Jandy
Part No. 6584). Never put more than two (2)
wires into each of the pins of the terminal bar.
7. Check all wiring, then apply power to both the
heat pump and the RS control system. Operation
can be verified in either Service or Auto mode. See
the RS Control System manual for instructions
about operation.
When the Jandy JE heat pump is first powered and
there is an RS control connected to the heat pump, the
display on the heat pump will show "JANDY REMOTE
ONLINE PUSH MENU TO DISABLE" . When the
JRT heat pump is online with the RS control, all
functionality of the control on the heat pump is disabled.
The heat pump functions can be controlled only at the
RS unit.
To temporarily use the heat pump controls, press
the button. The message "JANDY REMOTE
MENU
ONLINE PUSH MENU TO DISABLE" will disappear
from the heat pump display. All functionality has now
been returned to the control on the heat pump. In this
mode the RS unit is no longer controlling the heat
pump.
To return the functionality to the RS unit, cycle (turn off
and then turn on) the power to the heat pump, or press
the MENU button for 5 seconds to enter the User Setup
Mode and then enable the Jandy Remote.
NOTE If connecting more than two (2) items to the RS
Power Center red, 4-pin connector, a Multiplex
PCB is required.

Connection to a Secondary User Interface

1. Turn off the power to the heat pump.
2. Remove the three (3) screws that attach the front
panel to the heat pump and remove the front panel.
See Figure 9.
3. Remove the screw on the right side of the control
box.
4. Open the control box.
5. Run four (4) 22 AWG solid copper wires into the
low voltage soft membrane located on the lower
left-hand side of the heat pump. The wires may be
up to 300 feet (91.4 m) in length.
6. Connect the wires to the 4 position terminal on the
lower left-hand corner of the Power Interface PC
Board, labeled "User Interface1". See Figure 8.
The wires will be added to the existing wiring to
the User Interface installed on the heat pump.
