Water Module Wiring - Dimplex ECS150HP40A-580 Installation And User Instructions Manual

5.9 Water Module Wiring

All wiring must be carried out by a suitably
qualified person and must be fully compliant with
the current release
Regulations. For general wiring configuration see
Figure 7.
The water module has been pre-wired to ensure
minimal additional work is required by the
installer. The following summarises the required
electrical connections which the installer must
make:
 Primary connections, 5.9.1. A three core
cable must be connected between the supply
isolator and the cylinder connector block.
See Figure 7.
 Modbus connection,
communication cable between the cylinder
and heat pump must be installed. See Figure
8Figure 9.
 Zoned connections must be wired via the
cylinder PCB, i.e. circulation pumps and/or
zone valves, 5.9.3. See Figure 9.
 Temperature sensors and digital inputs can
be connected to the PCB, 5.9.4 (DI 01-05),
(NTC-DHW and NTC-Zone 1-4). See Figure
10.

Installation
5.9.1 Primary Electrical Connections
In both retro fit and new build installations, a 3
core cable must be taken from the isolator
[typically a 16Amp double pole fused spur] and
connected to the primary connector block as
illustrated in Figure 7.
 Live connection taken from a fused spur to
the cylinder connector block, [LHS grey
terminal].
 Neutral and Earth wires must be connected
to the blue and green/yellow connectors
respectively, as per Figure 7.
Note: Solid core cable or ferruled multi core
cable must be used
