Connecting the EasyTouch to Heater
1. Turn off the power to both the remote pool/spa
control system and the UltraTemp ETi™ Hybrid
Heater.
2. Remove the side panel of the heater cabinet, (you
do not need to remove the star-head screw at the
top left corner).
3. Remove the four (4) bezel retaining screws from
above the bezel and rotate the bezel downward.
This will allow you to access the Remote terminals
on the back of the heater control board for the
remote control installation.
4. Run the wires from the pool/spa remote control
system into the low voltage box.
5. Connect the wiring from the EasyTouch
Personality Board COM PORT to the RS-485
connection (J1) on the heater control Board.
Connect the green wire to J1 pin 2 and yellow wire
to J1 pin 3. Do NOT use pin 1 (red) or pin 4 (black)
wires. The connections are shown in the image on
page 16.
6. Rotate the bezel back into position and reinstall
the four (4) retaining screws.
7. Replace the side panel.
8. Restore power to the heater and the EasyTouch
control system.
9. Press the MENU SELECT button to scroll to
the Remote Mode screen. Toggle the selection
by pressing one of the arrows until the screen
displays “RS-485.”
10. Once the heater has been correctly configured,
a “heartbeat” indicator will appear on the main
screen each time a message is received from the
automation system.
Note: If the system is put into Service Mode at the
automation control panel the heater will not heat,
although it will remain powered on.
