Installation - RX Receiver unit 
1. Mount the RX wallplate onto the wall - cable access 
must be from behind or below the wallplate. 
Typical wiring diagrams, showing the interconnection 
between time controls and zone valves, are shown on 
pages 11-14.
NOTE: Earth connections are for customer use only.
2.  The RX receiver may now be mounted onto the wallplate 
and secured using the two screws on the bottom of the 
wallplate.
!
Important note: Please ensure that when positioning 
the thermostat setting unit that there are no large metal 
obstructions, ie cylinder or boiler case, sitting in between the 
thermostat and the RX receiver unit as these will block radio 
communication and prevent the thermostat from operating 
correctly.
