thermostats
A thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint.
Thermostats are used in any device or system that heats or cools to a setpoint temperature, examples include building heating, central heating, air conditioners, HVAC systems, water heaters, as well as kitchen equipment including ovens and refrigerators and medical and scientific incubators. In scientific literature, these devices are often broadly classified as thermostatically controlled loads (TCLs). Thermostatically controlled loads comprise roughly 50% of the overall electricity demand in the United States.A thermostat operates as a "closed loop" control device, as it seeks to reduce the error between the desired and measured temperatures. Sometimes a thermostat combines both the sensing and control action elements of a controlled system, such as in an automotive thermostat.
The word thermostat is derived from the Greek words θερμός thermos, "hot" and στατός statos, "standing, stationary".
I have a thermal store heated by a boiler with its own thermostat. I also have a stove with a back boiler. The stove heats water in a separate tank. There is a thermostat on this second tank that pushes hot water over to the store tank when it's hot. It's a closed loop and goes through a heat...

Hi I have a dual heating system ie separate thermostats for upstairs and down stairs, my question is why does my upstairs bathroom radiator come one when I turn my downstairs heating on ??

Hi all,
Would value your input.

I was curious as I saw these that work with the entire Viessmann control centre and wondered if anyone has installed them. They come in various packs of single, 2, 4, 6 stats.
They connect to the ViCare app and control, not sure what they do and how you control them.
Or how they play if you...

Hi,
We have one programmable thermostat in the landing of our house. This turns on/off all the heating rads and towel rails for the upstairs.

Hi,
I understand that the TSR temperature sensor is in the thermostat stem and not in the head, like with the TSE version - but what is the benefit of TSR over TSE?
Many thanks,
