We engineers love high tech controls. But this little #aquastat
has been a go to control for years. Strap on and remote bulb configurations for controlling pumps to keep domestic water tanks hot or domestic hot water pipes warm. Switches 24 to 240 VAC up to 4.2 amps for low voltage interface to zone managers or directly power a pump or burner.
We sometimes use them to make/break power to a pump if the solar/geo-thermal/wood boiler storage tank has been depleted so we can switch over to a gas #boiler
