Pool heater operating control module
The operating control for the appliance is the SMART
SYSTEM control module. It is located on the inside of the
control panel, behind the front access door. Access to adjust
the temperature set point and other user adjustable points
is made through the Operator Interface located on the front
access door.
The exact temperature set point is based on the system's
requirements. Set the control set point(s) to the desired
operating water temperature.
The maximum temperature set point that can be programmed
into the control module from the Operator Interface on a
pool heater is 105°F (40.5°C). The manual reset high limit
control for a pool heater is adjustable up to a fixed maximum
setting of 200°F (93°C).
