Description
The ETV Plus (Electronic Tempering Valve) is a hot water temperature control. It operates one or two electronic motorized mixing valves to regulate the system water temperature. It operates the electronic mixing valves using any of its voltages or a 4-20mA modulation signals. Its modulation PID is designed to respond quickly, which make it suitable for domestic hot water applications.
The ETV Plus consist of four primary components, the ETV Plus control; the electronic motorized actuator; the 3-way mixing valve; and an immersion temperature sensor. Heat-Timer offers two valve materials, bronze or stainless-steel. However, the ETV Plus package uses the Stainless-Steel valves. Depending on the valve material and valve size selected, the actuator used may vary.
For added protection, the ETV Plus control can be configured to close the hot water supply to the mixing valve if the mixed outlet temperature exceeds the Alarm Limit. It does that by operating a solenoid valve mounted on the hot water supply.
