The flexible dot matrix display uses easy 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 the user for adjusting temperatures or navigate through menus.\u003c\/p\u003e\r\n\u003cp\u003eChrono Proportional, Load Compensation control is the default heat regulation algorithm that will deliver increased comfort and improved economy over standard on\/o control. Standard On\/Off can also be selected.\u003c\/p\u003e\r\n\u003cp\u003eWhen chrono-proportional mode is set, the thermostat introduces a xed cycle rate on the system and then determines the duration of the On and Off periods within each cycle in proportion to load.\u003c\/p\u003e\r\n\u003cp\u003eThe control algorithm used to determine the on\/ off periods uses a proportional + integral (PI) routine to eliminate offset normally associated with on\/off or simple proportional control.\u003c\/p\u003e\r\n\u003cp\u003eChrono-proportional control signicantly improves comfort and generally improves boiler efficiency by optimising water temperature.\u003c\/p\u003e\r\n\u003cp\u003eFor TPOne OpenTherm we have redesigned the heating startup options. Standard startup is default giving instant heat at the scheduled time. New dynamic Delayed and Optimised start features are also selectable. Delayed start will pause the heating startup at the scheduled time dependant on the difference between ambient and required temperature which will decrease energy usage. Optimised start will monitor the difference between ambient and required temperature and will calculate the best time to start heating to hit setpoint at the scheduled time.\u003c\/p\u003e\r\n\u003cp\u003eBoth features dynamically adjust according to performance accuracy each day to ensure most acurate control and remove the need for manual setting and adjustment.\u003c\/p\u003e\r\n\u003cp\u003eAdditional TPOne OpenTherm features include:\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eSeperate User \u0026amp; Installer Setting Menus\u003c\/li\u003e\r\n\u003cli\u003eHoliday Scheduler\u003c\/li\u003e\r\n\u003cli\u003eUpper and Lower Temperature Limits\u003c\/li\u003e\r\n\u003cli\u003eCapacitive Touch Button Control\u003c\/li\u003e\r\n\u003cli\u003ePush Button Lock\u003c\/li\u003e\r\n\u003cli\u003e°C or °F Selectable Display\u003c\/li\u003e\r\n\u003cli\u003eAudible Button Click (selectable)\u003c\/li\u003e\r\n\u003cli\u003eFrost Protect Temperature Setting\u003c\/li\u003e\r\n\u003cli\u003eSelectable Domestic Hot Water Channel (Mains Variant only)\u003c\/li\u003e\r\n\u003cli\u003eClear Text Display (7 Languages)\u003c\/li\u003e\r\n\u003cli\u003eExternal Sensor\/Window Switch input\u003c\/li\u003e\r\n\u003cli\u003eBoiler service interval timer (400 days)\u003c\/li\u003e\r\n\u003cli\u003eOpenTherm v. 4.1\/5.0 certied\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cp\u003eTPOne OpenTherm Comfort Modes\u003c\/p\u003e\r\n\u003cp\u003eTPOne OpenTherm Programmable Room Thermostat introduces the quick access Scenario interface. To the left of the display are 4 dedicated user buttons. As a programmable device heating is controlled by a preset schedule but sometimes our schedules change intermittently so we have made it easy for the user to adapt their heating needs.\u003c\/p\u003e\r\n\u003cp\u003eThe Home, Away \u0026amp; Asleep buttons allow the user to quickly change the current setting to either save energy or deliver comfort when needed.

Standby remains until the user chooses to switch back on.\u003c\/p\u003e\r\n\u003cp\u003eTPOne supports OpenTherm boilers. If an OT boiler is connected to TPOne, it automatically starts controlling the boiler by this ecient control algorithm.
