Connecting the Zone 2 Room Sensor
The second zone sensor is used to sense the
temperature in the second heating zone of the dwelling.
All the installation guidelines for the touchscreen apply
to the Zone 2 room sensor- installation height, avoiding
heat sources, etc.
The second zone sensor requires a two core 0.75mm2
cable and it is not polarity sensitive.
The sensor is connected to ‘B4’ and ‘Gnd’ on the
controller.
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.
