USE OF THE TEMPERATURE CONTROL
5.1 Presentation
The digital regulation thermostat is supplied installed on the exchanger, including its electrical
connections, and is factory preset for a swimming pool heating application.
Principle
: a regulation sensor placed at the point where the water enters the swimming pool from the
exchanger measures the pool temperature (with the filtration system running), and compares this value
with the set temperature. If the temperature of the pool drops or is below the set temperature, the
thermostat switches the heating on (power to the primary heating circuit circulation pump). The "REG"
indicator flashes then stays on.
1. digital display to see both the pool water temperature and the set temperature,
2. “SET”: key to read or change the set temperature
3.
: touch sensitive button to increase the set temperature
4.
: touch sensitive button to reduce the set temperature (or switch off the “beep” sound indicating a
fault)
5. “REG”: regulation indicator: on = digital thermostat in “on demand” mode or flashing = activation of the
time delay before primary heating circuit pump switched on
6. “S1”: “on/off” switch (+ indicator)

5.2 Setting the required temperature
Press the “SET” key to display the set temperature, then keep it pressed and press the
key to
increase it or the
key to reduce it. Then release the “SET” key in order to return to the pool
temperature display.

6.1 Operating conditions
The temperature of the water circulating in the exchanger must be between 2°C and 40°C (maximum
temperature permissible in the primary circuit: 90
o
C, minimum temperature in the primary circuit 45
o
C for
good power restitution).
Before switching the device on, you need to make sure:
• the hydraulic fittings are correctly tightened,
• there is no leak,
• the appliance is correctly fixed to the wall,
• the connections of the electric cables are correctly tightened.
Incorrectly tightened cables may cause overheating of terminals,
