No wiring is required for the CentaurPlus C17ZW programmer plus thermostat solution. This makes it ideal as a ‘quick fit’ replacement for an old programmer, or programmer plus thermostat. The battery-powered companion wireless thermostat can be placed almost anywhere in the property, without the need for any wiring.
The TPI algorithm utilised by the companion thermostat maximises the efficiency of condensing boilers. In combination with the daily optimisation of heating schedules provided by the programmer, the overall energy saving is well in excess of that offered by a simple timer and basic thermostat.
It provides a 7-day time profile, with up to 3 on/off times for each individual day of the week.
Automatic GMT/BST time adjustment eliminates the need for manual clock adjustments, and a rechargeable backup battery maintains the clock in the event of a power outage.
CentaurPlus C17ZW works with most domestic gas, solid fuel and oil-fired central heating and hot water systems.
