Table 4: Schematic codes information
Millbrook House, Grange Drive, Hedge End, Southampton, SO30 2DF
Selecting Next will bring you to the Schematic menu, as shown in figure 16.
The schematic number refers to one of the plumbing schematics described in
the Appendices section.
Please ensure that your plumbing reflects the diagram set up to ensure correct
operation. The schematic coding is explained below.
Numbers that are shaded grey do not change. These are determined by the type
of device being installed.
Numbers not shaded are determined by the type of installation being used.

2: mono-energy (heat pump + electric back-up)
3rd Digit
3: bivalent (heat pump with boiler as back-up)
0: no DHW function
2: using immersion heater (for top-ups above the
4th Digit
maximum achievable temperature of the heat
pump)
number of zones (up to 4 zones with UI and
6th Digit
temperature probe instead of thermostat)
1: space heating only
7th Digit
9: space heating + DHW
The example schematics 1 and 2 (appendix) would
therefore both use the schematic code 10220290, as
they are both;
• mono-energy systems
• using an immersion heater
• two zones
• space heating and DHW functions
The difference between examples 1 and 2 is that
example 1 shows an example of a system requiring an
open by-pass while example 2 requires the installation
of a spring by-pass.
