WARNING
This Heat-Timer control is strictly an operating control; it should
never be used as a primary limit or safety control. All equipment
must have its own certified limit and safety controls required
by local codes. The installer must verify proper operation and
correct any safety problems prior to the installation of any
Heat-Timer control.

OVERVIEW
The ETS-LT is a pre-piped and pre-wired assembly that includes the ETV Platinum Plus (Electronic Tempering
Valve). The ETV Platinum Plus is a hot water temperature control capable of operating an electronic motorized
mixing valve to regulate the system water temperature. The electronic mixing valve is controlled using a voltage
output modulation signal. Its modulation PID is designed to respond quickly, which makes it suitable for domestic
hot water applications.
The ETS-LT assembly consists of the ETV valve with actuator, ETV Platinum Plus control module and a probe (direct
immersion) sensor on the Mixed Outlet, piping from the valve. The ETV valve, control module and piping assembly
components are mounted on a Unistrut frame that allows mounting on a wall.
For added protection, the ETS-LT assembly is configured that on a loss of power condition the ETV actuator will
power the valve to a full COLD position.
There is an optional ETV/HTLV Plus mode of operation in which on conditions where the mixed outlet temperature
exceeds the Alarm Limit the ETS will power the ETV valve to a full COLD position, powers CLOSE an option
High Temp Limit valve and enters into a manual reset condition. For additional information on the optional High
Temp Limit valve wiring, see page 20 and for the LOCKOUT menu see page 38.
