It can provide individual room temperature control as part of a properly configured underfloor heating installation.
Its simple manual operation makes it a useful option for rooms where advanced scheduling and smart controls are not required.
Central Heating and Boiler Control
The DS1 is also suitable for compatible conventional and combi-boiler heating systems.
It can be used with an external heating programmer to provide timed heating operation, while the thermostat regulates the required room temperature.
This makes it a practical option for replacing a traditional room thermostat in a compatible wired heating installation.
