  • Horstmann ServicePlus S11R

The ServicePlus range of programmers and timeswitches are designed to carry out a full or partial boiler shutdown once the servicing date has become overdue.

The Installer can set the ServicePlus so that either a full shutdown will occur after a 28 day warning period of the boiler service becoming due or a partial shutdown can be selected where a 15 minute period of heating and hot water will occur every hour. These 15 minute periods will occur every hour but never consecutively from one hour to the next.

If programmed on installation, the 15 minute ‘On’ periods will reduce the effectiveness of the heating system so that it becomes uncomfortable for the occupier without it providing no heating at all. This should have the effect of encouraging the householder to call the service engineer to check the system.


ServicePlus is a range of programmers and time switches developed to facilitate compliance with the Gas Safety (Installation and Use) Regulations 1998. Although not intended to replace the normal servicing regime, ServicePlus can act as a supplementary reminder to enabling compliance.

Features an upgraded back lit display screen and incorporates an automatic GMT/BST clock.
