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

Can replace 087N785100?
Yes it can.
Once you have pressed holiday mode is it on that until you press it on your return
When you choose holiday mode, you will need to input how long you are on holiday for. It will bring the heating back on automatically on the day you return.
Hello, We have just had this thermostat installed. We have set the thermostat for two home periods, one in the morning and one in the evening. The heating does not seem to go off when it should do -the display is showing it is still on. I then set it to sleep mode over night to get round this, expecting it to be over ridden in the morning and the heating to come on at the desired time. This didn't happen and it stayed in sleep mode. Please can you help?
Hi. Please call support on 0330 808 6660.
Is this the battery powered programmable thermostat?
Yes it is.
Hi, Can I replace TPone B with TPOne S thermostat? Does TBone B provide control via a mobile App? Regards,
Hi. It would be a fairly involved job as you will need to add a mains power supply. I would recommend the Delta Dore 5000 as an easier install. HCO Code 07A28. It just connects to the same 2 wires as the TPOne-B.
Hello How do I set this thermostat to come on and go off manually. Thank V Holden
Just go into the Menu and then Heating Mode. You can then turn it up and down as required.
how many switchings for each day of week
You can have up to 3 'home' temperature periods per day.
