the boiler at regular intervals to maintain a set temperature,

Some existing thermostats will have a Neutral and/or Earth wire connected. These
are not required by the TP5000 and must NOT be connected to any TP5000 terminals.
Instead they should be made electrically safe and coiled in the recess at the back of
the TP5000.
RX Receiver Wiring (RF models only)
RX1 & RX2
1) For mains voltage operated systems link terminal 2 to mains live supply.
2) Power supply to unit must not be switched by timeswitch.
