TPOne Programmable Room Thermostat platform delivers new levels of user friendly interaction. 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 are given on the what buttons 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 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 offset normally associated with on/off or simple proportional control.

Chrono-proportional control significantly improves comfort and generally improves boiler efficiency by optimising water temperature.

For TPOne 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.

Both features dynamically adjust according to performance accuracy each day to ensure most acurate control and remove the need for manual setting and adjustment.

Additional TPOne features include:

  • Seperate User & Installer Setting Menus
  • Holiday Scheduler
  • Upper and Lower Temperature Limits
  • Capacitive Touch Button Control
  • Push Button Lock
  • °C or °F Selectable Display
  • Audible Button Click (selectable)
  • Frost Protect Temperature Setting
  • Independant DHW Channel (Mains Variant only)
  • Clear Text Display (7 Languages)
  • Boiler Service Timer

Great website. Very quick delivery. A very positive description.
Great product, great service. What more can I say.
My heating programmer went U/S AFTER 10 years, that replaced after original installed 36 years ago. My heating engineer tried his suppliers that it could not be obtained but took about 3weeks to tell him. Said would need latest programmer with additional wiring. Could be costly. My electrician man located correct replacement, Delivered to door in 48hrs. Job done same day. House warm again. EXCELLENT SERVICE. SUGGEST USE WITH CONFIDENCE
