Observation:
If XSol diagnoses an issue with the mains power supply or with the external controls this page may help to determine if the issue is with the internal programmer in conjunction with XSol system diagnostics.
The optional programmer for this boiler operates in the same way as a normal programmer
(e.g. branded controls) and provides a terminal block to wire in additional controls, zone valves etc.
1. Mains power in (from fused spur).
2. CH/DHW ON/OFF from programmer to zone valves / cylinder / room stat.
3. Mains power to boiler (runs to 3 wire terminal block at side of boiler).
By default there is a link between this and HW ON, this will usually need
to be removed unless the system does not have a cylinder thermostat.
4. Gravity link, unless boiler is fitted to a gravity system the link should be removed.
