Communication Cable – Heat Pump
to Pre-Plumbed Cylinder unit
The communication cable between the Heat
Pump to Pre-Plumbed Cylinder unit is supplied
in the kit with the Cylinder unit. It is a pre-molded
Ethernet cable and does not require and
alteration.
The connection point on the Heat Pump is the
Ethernet port on the bottom of the unit, on the
front right-hand side.
The communication cable is connected to
‘Rx+’, ‘Rx-’ and ‘Gnd’ on the ‘Field Bus 1’ of the
controller. The cable core colours are clearly
labelled as the communication is polarity
sensitive.
Underfloor Heating Wiring
If the system incorporates underfloor heating
and an external wiring centre/ logic strip
and individual room thermostats, then the
touchscreen is only used to control the hot water
and ventilation functions of the system.
To enable this setup, the Digital Inputs (DIN) on
the controller of the Pre-Plumbed Cylinder unit
must be utilized.
The wiring centre/ logic strip must support a
volt free output via a relay to enable the heating
signal on the controller of the Pre-Plumbed
Cylinder unit.
The heating signal enable is to be wired using a
two core 0.75mm2 cable and it is NOT polarity
sensitive.
The sensor is connected to ‘DI1’ and ‘Gnd’ on
the controller.
