Connecting a program-controlled pump
1.Connect phase (L), neutral (N) and earth (
) to terminals 10, 11 and 12 as stated in the table (3.11.2 "Preparation").
2.Fit the cable in the strain relief.
3.If you have no more connections to make:
-Fit the cap on the electrical terminal block.
-Fit the plastic covers onto the appliance.
3.11.7Connecting an extra ON mode switch ("Tank ON")
Tank ON is a facility for connecting an external ON/OFF switch. In the OFF position, the programmed operating mode is active. In the ON position, the programmed operating mode is overruled, and the "ON mode" is active.
1.Connect cables (X3 and X4) to terminals 5 and 6 as indicated in the table (3.11.2 "Preparation").
2.Fit the cable in the strain relief.
3.If you have no more connections to make:
-Fit the cap on the electrical terminal block.
-Fit the plastic covers onto the appliance.
3.11.8Connecting an extra error signal ('Alarm OUT' )
Alarm OUT is a potential free terminal that is switched when an error is detected. This can be used to signal errors, for example with a lamp. A 230 V circuit can be directly powered. Other voltages require a relay prescribed by the manufacturer.
1.Connect the phase cables (X1 and X2) to terminals 13 and 14 according to the table (3.11.2 "Preparation"). If required, connect earth (
) to terminal 15.
2.Fit the cable in the strain relief.
3.If you have no more connections to make:
-Fit the cap on the electrical terminal block.
-Fit the plastic covers onto the appliance.
3.11.9
3.12Electrically connecting the solar heating system controller
Connecting communication cable to solar heating system
You must connect a communication cable between the controllers of the appliance and the solar heating system.
1.Connect the cables (X5 and X6) to terminals 1 and 2 as indicated in the table (3.11.2 "Preparation").
2.Fit the cable in the strain relief.
3.If you have no more connections to make:
-Fit the cap on the electrical terminal block.
-Fit the plastic covers onto the appliance.
