Cable type
Use the up/down arrows to select HWAT-Y2 or
HWAT-R2 cable used in your installation. Press
Enter.

Use the up/down arrows to select 208 V or 240 V
(applied voltage to the cable). Press Enter.

If your design requires that the ambient temperature
is significantly different from one location to another,
you will need an HWAT-ECO controller for each ambi-
ent condition.

The maintain temperature setpoint is the water tem-
perature that you set for normal use. Use the up/
down arrow keys to select the temperature.
