The Oso hot water surface-mounted thermostat Where stored in a cylinder and heated by a separate boiler, a dual control thermostat is required to avoid the cylinder being overheated. The thermostats are designed to restrict the water temperature to around 65C to provide safety and prevent scalding water running through the pipework. The dual thermostats also have an integrated reset button in the case of one of them tripping out. Some of the older style unvented cylinders would have a single control thermostat and a separate cutout thermostat.
