The STTR-060 W-225 was designed to complement the basic water heater relays in the range, offering additional features and functions. It integrates two different timers: one analog with local control and one Smart relay for remote control.

The device has four control inputs: one analog for NTC thermal sensor, one digital for Dallas DS18B020 thermocouple, and two contacts for remote control and feedback operation.

Through the Smart relay, the creation of scenarios is possible that allow the water heater to be turned off when the water temperature reaches a desired level.

Control of the water heater is achieved through an integrated load relay of 2 x 25A, without the need for extra equipment.

It is the first water heater control device that also disconnects the neutral supply wire.
