TPOne Programmable Room Thermostat platform delivers new levels of user-friendly interaction. The flexible dot matrix display uses easy-to-read icons and text information to provide feedback on status and settings to the installer and user. When the display is activated the backlight illuminates and guides are given on the buttons that will adjust temperatures or navigate the setting menus. Chrono Proportional, Load Compensation control is the default heat regulation system that will deliver increased comfort and improved economy over standard on/off control. Standard On/Off can also be selected. When a chrono-proportional mode is set, the thermostat introduces a fixed cycle rate on the system and then determines the duration of the On and Off periods within each cycle in proportion to load. The control algorithm used to determine the on/ off periods uses a proportional + integral (PI) routine to eliminate offsets normally associated with on/off or simple proportional control. Chrono-proportional control significantly improves comfort and generally improves boiler efficiency by optimizing water temperature. For TPOne we have redesigned the heating startup options. The standard startup is default giving instant heat at the scheduled time. New dynamic Delayed and Optimised start features are also selectable. The delayed start will pause the heating startup at the scheduled time depending on the difference between ambient and required temperature which will decrease energy usage. The optimized start will monitor the difference between ambient and required temperature and will calculate the best time to start heating to hit the setpoint at the scheduled time. Both features dynamically adjust according to performance accuracy each day to ensure the most accurate control and remove the need for manual setting and adjustment.
