Thermostats – FAQS:Â
What is a thermostat?
A thermostat is a device that controls the temperature of a heating or cooling system by turning it on or off based on a pre-set temperature.
What does a thermostat do in a boiler system?
A boiler thermostat detects the current temperature and signals the boiler to turn on or off to maintain the desired temperature. Through maintaining consistent temperatures, the thermostat ensures comfort, prevents overheating, and improves energy efficiency in your heating system.
Can I use any thermostat with my boiler?
No, you should check your boiler’s specifications to ensure the thermostat works with your system as not all thermostats are compatible with every boiler.
How often should I replace my thermostat?
Typically, thermostats can last around 10-15 years but could need replacing sooner if they fail, are outdated, or lack features like energy efficiency tracking.
How do I troubleshoot a thermostat?
To trouble shoot a thermostat, you may want to:Â
- Ensure the thermostat has power, if there’s no power, replace batteries or check the circuit breaker for wired models
- Confirm the thermostat is set to the correct settings, including mode and temperature
- Gently clean to remove dust or debris, as it can interfere with sensors
- Test if the boiler responds to adjustments, if not, there may be a communication issue
- Inspect for loose, frayed, or disconnected wires, if the thermostat is wired
- Reset the thermostat to resolve software or calibration issues, if this reset function is availableÂ
If issues persist, consult the manual or call a professional.Â
