Horstmann CentaurStat Data Sheet
CentaurStat
Electronic Programmable room thermostat
A single circuit combined time and temperature control
allowing up to six different temperature levels to be
programmed over a 24 hour cycle. The 7 day version allows
different days of the week to have individual programmes
whereas the 24 hour version allows the same programme to
be repeated daily.
Centaurstat is battery powered to allow easy replacement of
an existing room thermostat with no extra wiring needed.
Voltage free contacts make it ideal for the control of Combi
boilers. TPI energy saving software reduces energy usage by
its close temperature control when compared with old style
mechanical thermostats.

Specification
CentaurStat
The Centaurstat can replace any existing room
thermostat without the need to add any additional
cabling. This is because the Centaurstat runs on 3 AA
batteries meaning no separate mains supply is needed.
When used with an existing hot water and heating
programmer the heating programme should be set to
constant with the Centaurstat taking over the time and
temperature programme.
