Programmable thermostats provide different temperatures at different times of the day. Ideal for combi boilers and floor heating installations. The TP5000 Si range of programmable room thermostats offer easy to install and use 5/2 day thermostats with up to six tie 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 battery powered, hard wired and 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 making time setting or adjustment unnecessary. 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 patter within which boiler on/off percentages are varied to satisfy heating requirements. Chrono-proportional cycling rate 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.
