Elecro IN-LINE+ Installations- Und Bedienungsanleitung Seite 10

Time Switching Delay
To prevent overheating of the switch components within the heater
caused by frequent on and off switching (cycling), the In Line + digital
controller has been pre-programmed with a time delay function. This
prevents rapid fluctuations in temperature or velocity from switching the
heater on and off more than once in a two minute period. The time delay
mode is indicated by the flashing LED next to the word HEAT on the
digital display.
Differential
When the pool water has reached the required temperature the heater
will switch off and will not switch back on until the water temperature has
dropped 0.6˚C. This value is known as the differential and is also in place to
prevent overheating of the switch components caused by cycling.
Pump Interlock Cable
The In-Line + heater is supplied complete with a pump interlock cable that
connects into the left hand side of the heater enclosure, directly below the
power in cable entry gland.
To connect simply remove the rubber protection cap from the female
connector fitted to the heater enclosure, insert the male connector
supplied on the 5m cable. When fully inserted rotate the locking nut onto
the female connector so that the connector is locked in position.
The end of the cable has 2 wires that need to be connected in order to
by-pass the time clock controlling the swimming pool pump.
NOTE: Do NOT connect the pump interlock cable directly to the
swimming pool pump as this will result in overloading the heaters
digital controller. (See circuit diagram at back page).
Maximum permitted load is 5-Amp
