Note :
• option of connecting a remote "on/off" signal (terminals 1 and 2), with a 2 x 1.5mm
diagram below and wiring diagram (for example: in France: EJP or time delay contact, remote control contact, or
telephone modem contact...),
• the acceptable tolerance of tension variation is ± 10% while working,
• electric cables shall be fixed.

5. USE OF THE CONTROL DISPLAY

5.1 Presentation

The digital regulation thermostat is supplied installed on the heater, 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
heater 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": switch "on/off" for the 1
7. "S2": switch "on/off" for the 2
8. thermostat fuse housing
9. electrical connectors
5.2 Setting the required temperature
Press the "SET" key to display the set temperature, then keep it pressed and press the
increase it or the
temperature display.
