5.2. P-156 Control Adjustments
The P-156 has a digital control system. The pool heater
(chauffe-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.

5.2.1. MENU/SET Button
The MENU/SET button is used to select POOL or
SPA operation. It allows the user to turn the heater off
electronically. The LCD remains energized and displays
OFF, while continues to show the actual water temperature.
5.2.2. Temp Buttons
If the heater is in POOL or SPA mode, the desired water
temperature (SETPOINT) will be displayed and may be
adjusted using the UP or DOWN buttons.
5.2.3. Operation
In the POOL or SPA modes, the actual water temperature
is displayed along with the desired water temperature
(SETPOINT). When the water temperature is above the
setpoint, “Water Temp” will alternate with “No Demand.”
When the water temperature is below the setpoint and the
heater is firing, “Water Temp” will alternate with “Heating.”
To adjust the setpoint temperature, make sure the control
is in the appropriate mode (POOL or SPA) and push the UP
or DOWN buttons.

Strength indicator, which indicates the pilot flame current
using a bar graph and numerical display. A signal of less
than 4 bars indicates a weak flame signal and may require
service. Refer to the Troubleshooting section for possible
causes and corrections.
