CONNECTING TO AN AUTOMATION SYSTEM

Remote Operation

The UltraTemp ETi™ Hybrid Heater may be connected
to an automation system via the remote spade
terminals on the back of the control board (see page
17) or via the RS-485 communication connector on
the back of the control board (see page 18). Refer to
the EasyTouch ® Control System Installation and User's
Guide for more information.
Remote connection via the RS-485 connector is only
available on EasyTouch software version 2.169 or
later. All other automation packages must connect
via the ¼ in. "Spade" terminals (spade connector not
supplied).

Relay Remote Controls

Electrical wiring must be in accordance with the latest
edition of the NEC (NFPA 70) in the United States
and CEC (CSA 22.1) in Canada, unless local code
requirements indicate otherwise.
To connect remote control equipment to the
heater, perform the following steps:
1. Turn off the power to both the remote pool/spa
control system and the 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).
