Gravity-Fed And Part-Pumped Systems; Stand-Alone Installation - Hive Active Heating Installation Manual

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
heating relay opens a valve, operates a pump,
or both, to divert hot water to the heating.
If you are installing into a gravity-fed or part
pumped system, complete the wiring and then
switch the Hive receiver to 'gravity-fed' mode
as follows:
Switch off the power to the boiler and receiver.
1
Wait at least 5 seconds, then switch the
2
boiler and receiver back on.
Press and hold the hot water button for at
3
least 10 seconds.
The receiver status light will show BLUE when
entering 'gravity-fed' mode. Or GREEN for 'fully
pumped' mode. Fully pumped mode is the
default for new devices.

Stand-alone installation

For Hive Active Heating™ a hub, a receiver and a
thermostat are installed together. Where this
service has not been purchased, the thermostat
and receiver can also be installed without a hub.
This is known as 'stand-alone' mode.
In stand-alone mode the thermostat acts as a
normal wireless thermostat with none of the
benefits of Hive Active Heating™.
At any time you can check what mode the
receiver is set to by switching the receiver's
power off then on. When power is restored the
status light will flash for 5 seconds – amber
for Hive Active Heating™, white/pink for
'stand-alone' mode.
