Important information: Gravity-fed and part-pumped systems
Gravity-fed and part-pumped systems are wired differently to standard
boilers. With these, the hot water relay switches on the boiler, whilst the
heatin relay opens a valve, operates a pump, or both, to divert hot water
to the heatin. If you are installin into a ravity-fed or part pumped system,
complete the wirin and then switch the Hive receiver to ‘ravity-fed’ mode
as follows:
1
Switch off the power to the boiler and receiver
2
Wait at least 5 seconds, then switch the boiler and receiver back on
3
Press and hold the hot water button for at least 10 seconds
The receiver status liht will flash BLUE for 3 seconds when enterin
‘ravity-fed’ mode. Or GREEN for ‘fully pumped’ mode. Fully pumped
mode is the default for new devices.
