The MK18 range off ers fl exibility and reliability, with an elegant look and some handy features. All models have a slim, modern enclosure and a large LCD with a convenient back light. Employing the latest technology, these versatile heating time controls are reliable and easy to use. They are the installer’s fi rst choice due to their ready interchangeability with most other existing controls. All models have real time and date set in the factory and automatically display the correct time when powered up. The time and date information is used to automatically change between summer and winter time on the right day each year without user intervention, substantially reducing the number of call backs. All products also incorporate an optional installer set service interval timer for use in tenanted properties where the landlord is responsible for gas safety. This feature allows the service due date to be set and starts to remind the user 28 days before the due date. Each model can be confi gured by the installer at time of installation to provide 7 day, 24 hour or 5 day/2 day operation. All models can also be confi gured to provide either 2 ON/OFF’s or 3 ON/OFF’s per day.
