Programmable thermostats provide different temperatures at different times of the day, ideal for Combi boiler and floor heating installations. The TP5000 Si range of programmable room thermostats offers easy to install and use 5/2 day thermostats with up to six time and temperature changes each day with different programmes for weekdays and weekends. Mains or battery powered for ease of installation, the TP5000 Si has a large, easy-to-read LCD display. It is easy to programme and operate because of a built-in switching programme that the user can easily change to suit individual heating requirements. The TP5000 Si is also available in wireless (RF) versions. A big plus with the TP5000 Si is that it incorporates a real time clock and calendar function which eliminates the need for time-setting and BST/GMT time changes. Time and date are factory-set. Chrono-proportional control is the standard setting for the TP5000 Si but advanced conventional ON/OFF control is an installer-set option. This modulating control mode uses a cycling pattern within which boiler on/off percentages are varied to satisfy heating requirements. Chrono-proportional cycling rates of 3, 6, 9 or 12 per hour can be selected. The optional Service Interval Function incorporated into the TP5000 Si helps landlords meet the boiler servicing requirements of Gas Safety Regulation 36. The unit provides audible and visual warnings from 28 days before servicing is due and ultimately reduces the heating output should the due date pass. Full heating operation can only be restored by an authorised installer.
