5.2. P-156 Control Adjustments
The P-156 has a digital control system. The pool heater
(chaue-piscine) touchpad, located on the upper front
panel of the heater, allows the user to select either POOL
or SPA operation, and to adjust the setpoint temperature.
The LCD display window indicates the mode (OFF, SPA,
POOL) and the actual water temperature. A manual power
switch provided below the touchpad turns the control
power ON or OFF.
