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 cylinder. The programmer

DT10RF optimiser
A seven day digital programmable RF thermostat with a seven day programmer/ receiver in
the boiler fascia. The transmitter is the tried and tested optimiser as available with other

Greenstar 30CDi System boiler when
used with optional diverter valve kit
Increased SAP ratings
As well as the CDi models 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.
