What it is

The Horstmann AS2 Thermoplus is a room thermostat manufactured by Horstmann Controls. It is used to measure and control the air temperature in a room and to signal the heating system to bring the space up to the set temperature. It sits within the clocks, timers and programmers group of heating controls.

Before you order

  • Check the model reference on the existing thermostat against AS2 Thermoplus before ordering.
  • Confirm the control arrangement of the heating system is compatible with a room thermostat of this type.
  • Have the installation instructions to hand so wiring and mounting are carried out to the manufacturer's guidance.
