General system - explanation for householder
The CentaurPlus ZW is a timeswitch which is connected to its own room thermostat - the
HRT4-ZW - using the latest Z-wave wireless technology.
Where it has been used to replace your existing time control it is likely that there was no
room thermostat fitted previously.
The addition of this room thermostat will make considerable energy savings which
independent tests have shown could be as much as 10% off your energy bills.
The thermostat uses the latest micro-processor controlled energy saving software – known
as TPI - which is a very accurate temperature control method compared to older style
mechanical room thermostats. It runs on two AAA batteries which should last more than
2 years and a battery low indicator will appear in the display of the thermostat when
they need changing.
The CentaurPlus ZW timeswitch is mains powered with a reserve battery to retain its
memory during power cuts. It will allow up to 3 On/Off settings per day for each day of
the week and has a 1 hour boost button and an On/Off advance button.
There is also a programme override allowing the permanent selection of OFF/ON/AUTO/
ALL DAY.
