A. 

Underfloor with Aube Thermostat 

The schematic below illustrates the set up for the commissioning steps that follow.  

 

A1.  Check all wiring connections 

  Ensure BT8 (DHW Sensor) and BT9 (Buffer Tank Sensor) remain connected and left 

placed inside the wiring module.  

  Check BT1 and BT2 probes are in the correct pockets. 

  Heating is controlled with the Aube Thermostat. It must be connected to SA1, via a 

relay. The schematic on the next page shows an Omron Relay and the relevant 
connections. Should an alternative relay be used please ensure you check the 
required connections and wire as necessary. 

  It is recommended that a flow switch is installed. Should you not install a flow switch 

then it is necessary to install a bridge between terminals 39 and 40.
