3.12.7 Connecting communication cable
Note
>The communication cable must always be connected, otherwise neither
the appliance nor the solar heating system controller will run.
1. Connect the double connector to J16.
2. Fit the cable in the strain relief.
3. Connect the other end of the communication cable to the terminal block of
the appliance. See
-
connecting communication cable to the appliance (3.12.7 "Connecting
communication cable").
- electrical diagram for the appliance (17.3 "Electrical diagram for the
appliance")
- electrical diagram for the solar heating system (17.4 "Electrical
diagram, solar heating system")
4. Connect the optional head pump (3.12.8 "Connecting extra head pump") or
Q/T sensor (3.12.9 "Connecting Q/T sensor").
5. If you do not need to make any more connections:
- Fit the cover over the controller.
3.12.8 Connecting extra head pump
Note
This pump is essential if a greater head is required. When the system has
such a high resistance (>66 kPa) that the pump in the pump station is
insufficient, you can connect a second (ON/OFF) pump to the solar heating
system controller.
1. Connect earth ( ), live and neutral to terminals 7 through 9.
2. Fit the cable in the strain relief.
3. If you need to connect an extra head pump, continue (3.12.9 "Connecting
Q/T sensor"); otherwise:
-
Fit the covers over the controller.
3.12.9 Connecting Q/T sensor
Note
You can optionally add a Q/T sensor to the installation. This enables you to
calculate the energy contribution of the system. For more information or to order
the Q/T sensor, please contact your supplier.
1. Connect the 5V to J12-1.
2. Connect sensor S
4
to J12-2.
3. Connect earth to J12-3.
4. Connect the "flow signal" to J12-4.
5. Fit the cable in the strain relief.
6. If you have no more connections to make:
- Fit the covers over the controller.
