TVS43R is an Electronic Tempering valve system used to control domestic hot water. With ModBus Communication as standard.

The TVS43R is similar to the TVS43, however it features an upgraded actuator that will drive the hot port shut automatically on loss of power. The power to the actuator is wired through the relay in the TC250D control so that the power is interrupted during a high temperature condition.

The package ships with a hard copy of the installation instructions printed on waterproof, tear resistant paper that should remain onsite.
