Optional plug-in controls
Greenstar Highflow CDi floor standing condensing combi boilers are available with a range of easy-to-use controls. These
fascia-mounted controls offer simple plug-in connection to the boiler circuit board.
Mechanical timers
MT10 mechanical timer
The simplest Worcester control device – an easy-to-use analogue clock for setting heating
time periods. It plugs into the boiler fascia via a pre-prepared plug and socket.
MT10RF mechanical RF thermostat
Has an analogue display for setting night and day time periods and temperature. The
receiver plugs into the boiler and is activated remotely by the RF (radio frequency)
controller, which requires no wiring. So installation is clean and simple – no disturbance to
floorboards or carpets. Nor is there any need for a separate room thermostat.
These mechanical timers do not control domestic hot water pre-heat. If this function is
required please select a digital programmer. Alternatively, an additional single channel timer
for hot water control, could be wired in remotely.
Digital and wireless programmers and room thermostats
DT20RF digital RF thermostat with twin channel programmer
A wall-mounted RF room thermostat with digital display, combined with a twin channel
digital timer in the boiler fascia. The fascia mounted programmer benefits from automatic
time and date setup, automatic summer/wintertime changeover and a backlight for use in
low light conditions.
DT20 twin channel digital programmer
A versatile, easy-to-learn, 7 day, digital programmer offering up to 3 on/off settings per day.
The programmer has a host of innovative features including automatic setup, which sets
the correct time and date at power-up, automatic summer/wintertime changeover and a
green backlight for use in low light conditions.
DT10RF digistat
A familiar wall-mounted 24 hour programmable RF digital thermostat combined with a
fascia mounted single channel programmer to time the hot water combi preheat functions.
The programmer includes a built-in receiver for the room thermostat and all of the
functionality of the DT20.
8
DT10RF optimiser
A seven day digital programmable RF thermostat with a seven day programmer/receiver in
the boiler fascia for hot water. The transmitter is the tried and tested Optimiser as
available with other Worcester boilers. The optimum start feature, where the thermostat
delays the firing of the boiler until necessary, is a useful energy-saving option.
TD200 text display*
A seven day programmer with easy-to-use text display with automatic time and date setup,
automatic summer/winter time changeover and a backlight for use in low light conditions.
Three on/off periods can be set per day. The TD200 can be fascia mounted or hard wired
outside the boiler using the optional wall mounting socket. The TD200 features an easy-touse full text display providing more information than standard digital controls. A hard wired
room thermostat is available to provide optimum start functionality.
RT10 room thermostat*
A hard wired optimising room temperature controller with digital display for use with the
TD200. The display shows current and desired temperature and an advance button allows
the user to move to the next heating switch point.
TD200 wall mounting socket*
A Worcester branded wall mounting socket which allows the TD200 to be hard wired away
from the boiler.
*All three of the above are classed as an Intelligent Combi package.
Increased SAP ratings
As well as the Greenstar Highflow CDi appliances achieving
very high SAP ratings for dwellings, the addition of the
optimising temperature controller further increases these
ratings as well as being part of the recommended best
practice, as covered by the CHeSS design standard.

maintenance contracts can be arranged through the
Worcester Customer Service Department.
Showers
When a loose head shower with a flexible hose is used over
a bath or shower tray, the hose must be fixed so that the
head cannot fall closer than 25mm (1in) above the top edge
of the spill over level of the relevant bath or shower tray.
Alternatively, the feed pipes to the shower should
incorporate a double check valve assembly or a check valve
and vacuum breaker.
With fixed head showers no provision is necessary.
The use of a thermostatically controlled shower will give
added comfort and safeguard against high hot water
temperatures.
Bidet
The supply of hot and cold water mains direct to a bidet
is permitted provided that the bidet is of the overrim
water feed type. The outlet(s) should be shrouded and
not have any temporary hand held spray attached. No
other anti-syphonage arrangements are necessary.
