specifications” for fuse/cable size and for
connection details.
Electrical Connection (Hot Water Cylinder
Electric Heater)
• The electric heater, incorporated in the hot water
cylinder, requires a separate supply to Hydro Unit.
• Connect the hot water cylinder heater electrical
supply in accordance with shown below:
Live conductor: Terminal L on Terminal Block 02
Neutral conductor: Terminal N on Terminal Block 02
Earth Conductor: Earth terminal on Terminal Block
02
• Connect the hot water cylinder heater to the Hydro
Unit as shown below:
Live conductor to hot water cylinder: Terminal 1 on
Terminal Block 03
Neutral conductor to hot water cylinder: Terminal 2
on Terminal Block 03
Earth conductor to hot water cylinder: Earth terminal
on Terminal Block 03

Electrical Connection (Hot Water Cylinder
temperature Sensor)
• Connect the hot water cylinder temperature sensor
as shown below to terminals 1 & 2 on CN20 in the
Hydro Unit.
• Please ensure that the interconnecting cable,
between the Hydro Unit and the hot water cylinder, is
connected to earth at both ends of the cable using
the shiel wire.

3-way mixing valve for 2nd zone
3-way mixing valve connection
Required controller specification:
Electrical specification: 230 V; 50 Hz; <100 mA
The 3-way mixing valve is required in order to achieve the
temperature difference in a 2-zone heating system.
• Connect the 3-way mixing valve with terminals 8, 9 and
10 at CN22 (for mixing valve type 1)
or terminals 7, 8 and 9 at CN22 (for mixing valve type 2).
• Connect the 3-way mixing valve as shown in the
following diagrams:
Electrical connection (electric heating system,
hot water cylinder)
• The electric heating system integrated
in the hot water cylinder requires a dedicated
connection to the hydro unit.
• Connect the hot water cylinder heating system
as follows:
Current-carrying: Terminal L to terminal strip 02
Neutral: Terminal N to terminal strip 02
Grounding: Grounding terminal to terminal strip 02
• Connect the hot water cylinder heating system
to the hydro unit as follows:
Current-carrying line on hot water cylinder:
Terminal 1 to terminal strip 03
Neutral line on hot water cylinder:
Terminal 2 to terminal strip 03
Grounding line on hot water cylinder:
Grounding terminal to terminal strip 03
Electrical connection (temperature sensor,
hot water cylinder)
• Connect the temperature sensor of the hot water
cylinder to terminals 1 & 2 at CN20 in the hydro
unit as shown below.
• Make sure that the connection cable between the
hydro unit and the hot water cylinder is grounded
at both ends with the shielded cable.
