- Page 2 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.

Page 4: Overview
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. -

Page 10: Installation Instructions
INSTALLATION INSTRUCTIONS The installation process for ETS-LT consists of the following basic steps: Initial installation (see “Design Considerations” on page 10). Mounting the ETS-LT assembly (see page 11). Connecting the ETS-LT assembly power wiring (page 15). Upgrade/optional wiring the ETS-LT (see page 40). -
Page 11: Selecting A Location For The Ets-Lt Assembly
• The ETS-LT is too heavy and bulky for a single individual to lift and attempt to mount. It is recommended that a minimum of 3 people are needed. The ETS-LT assembly should be support by 2 individuals while the 3rd individual does the mounting. -
Page 12: Applications Using Wood Studs
Set the ETS-LT assembly down on the floor. Drill a 1/4” diameter by 2” deep hole in the center of each mark. Reposition the ETS-LT assembly on the wall and align with the newly drilled holes. Insert the lag screws and washers through the unistrut frame into the holes and loosely tighten. -
Page 13: General Piping Guidelines
Use unions (provided) to allow for servicing and, if required, removal of the valve and other components. • Include drain valves (provided) to assist in servicing of the ETS-LT assembly. • Use a generous amount of pipe thread sealant. DO NOT use pipe thread tape. When using the valve in a domestic water application, ensure the thread sealant is compliant with domestic water application and meets NSF 61 requirements. -
Page 14: Recirculation Pump Sizing
Stagnant water provides ideal conditions for the growth of bacteria, such as Legionella. The flow switch should be located on the MIXED outlet field piping above the ETS-LT assembly. Activation of the flow switch should be at the lowest potential draw of the system. -
Page 15: Connecting The Ets-Lt Assembly Power Wiring
WARNING ELECTRICAL SHOCK HAZARD! To avoid the risk of electric shock, DO NOT re-connect electrical power until ALL wiring to the ETS-LT is completed. Failure to do so may result in severe personal injury or death. 059327–00 REV. C HEAT-TIMER CORP. -
Page 16: Ets-Lt Optional Field Wiring
Connect one of the 24Vac transformer outputs to the actuator COMMON terminal on Terminal Block F of the Motorized Ball Valve. Connect the second 24Vac transformer output to the HTLV Common terminal (12) on the ETS-LT Control module. Connect the HTLV normally closed (NC) terminal (11) on the ETV module to the Motorized Ball Valve actuator CLOSE terminal on Terminal Block F. -
Page 17: Wiring The Htlv Lockout Alarm (Optional)
WIRING THE HTLV LOCKOUT ALARM (OPTIONAL) NOTE The ETS-LT Control Module does not source power to the HTLV Lockout terminals. An external power source is required and must be connected in series as shown in the diagram. Run the alarm wire and the external power source wire through knockouts located on the bottom of the ETS-LT Control Module enclosure. -
Page 18: Wiring The 4-20Ma Remote Setpoint
WIRING THE 4–20MA REMOTE SETPOINT NOTE The ETS-LT Control Module does not source power to the 4–20mA terminals. The EMS system must provide the excitation voltage. Run the 4–20mA Setpoint wires through a knockout located on the bottom of the ETS-LT Control Module enclosure. -
Page 19: Completing The Wiring
Do not re-install the Enclosure wire cover at this point as access to the PROGRAM/RUN switch is needed for programing of the ETS-LT module. With power supplied to the ETS-LT, the power loss capacitor of the valve actuator requires about 2 minutes to fully charge. -
