02 DETAILED OPERATION
OVERVIEW
The ETV Platinum Plus (Electronic Tempering Valve) is a hot water temperature control capable of operating one or more electronic
motorized mixing valves to regulate the system water temperature. The electronic mixing valves are controlled using any of its
voltages or current output modulation signals. Its modulation PID is designed to respond quickly, which makes it suitable for
domestic hot water applications.
The ETV Platinum Plus consists of four primary components:
• The ETV Platinum Plus control
• The electronic motorized Actuator
• The 3-way mixing valve
• An immersion temperature sensor
If applicable for added protection, the ETV Platinum contains a power loss capacitor which will close the hot water supply to the
mixing valve on a loss of power. The ETV Platinum Plus control can also 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 HTLV (High Temp Limit Valve) mounted on
the hot water supply.
ETV OPERATING CONCEPT
The ETV Platinum Plus control modulates the electronic motorized mixing valve to maintain a temperature setpoint. It does that
by mixing two different water temperatures from two different sources; a hot water source and a cold-water source. The hot water
source can be a hot water boiler, a hot water coil in a steam boiler, or a hot water storage tank. The cold water comes from the city
water system. The cold water inlet is joined with the circulating loop return pipe to help maintain flow in the valve during periods of
no usage. The ETV Platinum Plus operation requires the use of a circulating loop pump to maintain the loop temperature.
To save on energy, the ETV Platinum Plus provides a 7-day schedule to help reduce the water temperature during periods of
low usage.
HTLV (HIGH TEMP LIMIT VALVE) OPERATING CONCEPT
In addition to maintaining the mixed output setpoint, the ETV Platinum Plus helps protect the system from excessive water
temperatures. It does that by closing a HTLV (High Temp Limit Valve) feeding the mixing valve’s hot water. When the mixed outlet
exceeds the alarming temperature setpoint (See “HTLV Setpoint” on page 49) for the delayed period (See “HTLV Trigger Delay” on
page 49), the control closes the HTLV (High Temp Limit Valve) blocking all hot water flow to the mixing valve and triggers an alarm.
ETV + HTLV OPERATING CONCEPT
The ETV + HTLV mode combines both the ETV and HTLV modes. In this mode, the ETV Platinum Plus controls the valve to maintain
temperature, and monitors the outlet temperature to ensure the specified temperature is not exceeded.

6|HEAT-TIMER CORP. 059305–00 REV. E
ETV PLATINUM PLUS INPUTS
SYSTEM TEMPERATURE SENSOR
The ETV Platinum Plus is designed to connect to the provided Heat-Timer temperature sensor probe with enclosure (P/N 904222–00).
The sensor must be installed within 1 to 3 feet (0.3 to 0.9meters) after the mixed outlet of the motorized mixing valve, and before
any takeoffs.
AUX SENSOR/SWITCH INPUTS—OPTIONAL
Auxiliary inputs connected to the ETV Platinum Plus can configured as temperature sensors or switch sensors. When configured as a
switch sensor, the ETV Platinum Plus detects an open or close switch contact.
When configured as a temperature sensor, the sensor monitors water temperature. When placed in the COLD and HOT inlet of the
valve, the sensor can be configured as Feed-Forward to provide an additional feedback to the control for maintaining the accuracy of
the desired setpoint temperature.
Auxiliary temperature sensors must be installed at least 3 to 6 feet (1.0 to 1.8 meters) from the valve, and after the cold and return
lines join together. When using the Feed-Forward feature it is recommended to install the Auxiliary Temperature Sensors at least 6
feet (1.8 meters) from the valve.
FLOW PROVE—OPTIONAL
The Flow Prove input checks for the flow status before opening the mixing valve. If no flow status exists, the control will keep the
mixing valve closed (fully COLD). However, if the no flow status occurs during normal valve operation, the ETV Platinum Plus will keep
the mixing valve position at its latest opening percent or return the mixing valve to a predetermine position as set by the installer.
4–20MA REMOTE SETPOINT—OPTIONAL
The 4–20mA remote setpoint can be used when it is desirable to set the ETV Platinum Plus setpoint remotely using an EMS system. Any
signal that is less than 2mA or greater than 22mA will close the mixing valve and trigger an alarm (See “Alarm Messages” on page 41).
02 DETAILED OPERATION
NOTE
Alarms for auxiliary sensors are available with RINET communication option only and is accessed via Internet
through BuildingNet.
NOTE
If the current valve position is lower than the preset valve position setting, the valve will remain at the current position.
It is the responsibility of the installer to properly select the flow switch and the gpm flow rate required for the switching
needed for the application.
NOTE
The ETV Platinum Plus does not source power to the 4–20mA terminals. The EMS system must provide the
excitation voltage.

059305–00 REV. E HEAT-TIMER CORP. |7
ETV PLATINUM PLUS OUTPUTS
ACTUATORS
When the Control Mode is set to ETV or ETV + HTLV, the control operates a single or dual motorized mixing valve to maintain the hot
water temperature at the Setpoint. This is done by sending 24Vac power and a modulation signal to the mixing valve.
During loss of power the actuator will automatically position itself and the valve to a full COLD position. Once power is restore the
actuator will return to normal operation.
HTLV (HIGH TEMP LIMIT VALVE)
When the Control Mode is set to HTLV or ETV + HTLV, the ETV Platinum Plus uses a HTLV (High Temp Limit Valve) to close the hot
water feed to the mixing valve when excessive mixed temperatures exceed the Alarm Limit (See “HTLV Setpoint” on page 49) for the
specified Delay Alarm period.
The control can manage either a motorized valve (powered OPEN and powered CLOSED) or a Normally Open (N.O.) or Normally
Closed (N.C.) solenoid type valve. Heat-Timer recommends the use of a motorized ball valve with battery backup HTLV valve for better
performance during power outages.
HTLV LOCKOUT OUTPUT
The HTLV Lockout can be used to provide a notification that the unit has gone into lockout. Devices that can be connected to the ETV
Platinum Plus include: Vis-U-Alarm, audible alarm, Remote Management System, or any other device that requires a switch closure or an
open switch to trigger an alarm.
The HTLV Lockout LED will be lit whenever the control is in lockout. To exit HTLV Lockout mode, the cause of the alarm must end or be
corrected, the System Sensor reading must drop below the HTLV Limit, and the Reset button must be pressed (See “Reset Lockout” on
page 54).
02 DETAILED OPERATION
NOTE
The ETV Platinum Plus does not source power to the HTLV valve terminals. An external power source is required.

02 INSTALLATION INSTRUCTIONS
The ETV Platinum Plus installation process consists of the following basic steps:
1 Initial installation (See “Design Considerations” on page 13).
• General piping—unions, isolation valves...
• Locating and installing the sensor(s).
• Piping the optional HTLV (High Temp Limit Valve). Reference the appropriate HTLV installation manual for additional
instructions
2 Installing the ETV mixing valve(s) (See page 16)
3 Mounting the ETV Platinum Plus Module (See page 20).
4 Mounting the Actuator to the mixing valve
5 Connecting the ETV Platinum Plus wiring (See “Wiring the ETV Platinum Plus” on page 22).
• Power wiring
• Output wiring
• Input wiring
6 Optionally connecting the ETV Platinum Plus to a communications network (See “Communications Wiring” on page 32).
Reference the ETV Platinum Plus Remote Communication manual for addition information.
7 Calibrating the Actuator (Refer to page 35).
8 Completing initial programming of the ETV Platinum Plus (Refer to page 43).
REQUIRED MATERIALS (NOT SUPPLIED)
The following materials/tools are required for installation, but are not supplied:
• General hand tools (screwdrivers, wire strippers, power drill, etc.)
• General plumbing tools (wrenches, pipe cutters, etc.)
• 18 AWG cable (Heat-Timer P/N 703001–01 or equivalent #18/2 cable)—used for ETV Platinum Plus wiring.
DESIGN CONSIDERATIONS
When installing the system, certain design considerations must be taken into account. These include:
• General Piping Guidelines (isolation valves, drain cocks, unions, etc...)
• Sensor Probe Locations
• Optional HTLV (High Temp Limit Valve) Piping
• Building recirculating loop
• Thermal Trap or proper use of check valves
• Dual/Parallel ETV Valve Piping
See “Piping Diagrams” on page 36 for more information.

14 |HEAT-TIMER CORP. 059305–00 REV. E
GENERAL PIPING GUIDELINES
The following guidelines must be observed when piping the system.
1 All piping, including the piping of the ETV valve body, must meet or exceed local, state, and/or federal guidelines, codes,
and regulations.
2 Support all piping using hangers. DO NOT support piping by the unit or its components.
3 Use isolation valves (as shown in Figure 2) to isolate system components.
4 Use unions (as shown in Figure 2) to allow for servicing and, if required, removal of the ETV valve and sensors.
5 Include drain valves (as shown in Figure 2) to assist in servicing of the ETV valve and sensors.
SENSOR PROBE LOCATIONS
Sensor probes must be installed within the flow of water in the pipe (see Figure 2). When possible, use a tee fitting rather than an
elbow fitting where the piping changes direction within the allowable sensor placement distance from the valve. The sensor probe is
then placed in the run of the tee fitting as shown as the System Sensor Probe in Figure 2.
When installing the probe sensor in a tee fitting, perpendicular to a run of piping, the tip of the probe sensor should be position at
the centerline of the piping (see optional HOT or COLD probe sensor in Figure 2). This may require a nipple and coupling in addition
to the tee fitting.
Refer To “ETV Platinum Plus Inputs” on page 5 for more information.
HTLV (HIGH TEMP LIMIT VALVE) PIPING
The optional HTLV is typically piped between the hot water source (a storage tank or boiler coil) and the Hot inlet of the ETV valve.
For an optional HTLV location, refer to “Piping Diagrams” on page 36.
FIGURE 2
PIPING GUIDELINES
04 INSTALLATION INSTRUCTIONS

059305–00 REV. E HEAT-TIMER CORP. |15
04 INSTALLATION INSTRUCTIONS
BUILDING RECIRCULATING LOOP
For proper operation of the ETV Platinum Plus, the ETV valve must be installed in a system with constant recirculation. The building
recirculation must be piped in a manner that allows recirculating flow to the COLD side of the ETV valve and to the water heating
source. Refer to “Piping Diagrams” on page 36.
The recommended size of the recirculation loop and pump should be as follows:
THERMAL TRAP
A thermal trap must be used to prevent the higher temperature water in the hot water supply source from migrating up and entering
the cold-water inlet side of the mixing valve during low or no demand periods. The thermal trap can be installed either up or down.
However, its drop must be a minimum of 32 inches (81.3cm) as measured from pipe-center to pipe-center.
In applications where piping a thermal trap is not feasible, or in applications where there is a recirculating pump between a heating
source and storage tank, a check valve may be used.
MULTIPLE/PARALLEL VALVE PIPING
For high volume applications the ETV Platinum Plus control module can modulate two or more valves piped in parallel while
maintaining a single setpoint temperature.
When piping multiple valves in parallel it is very important to ensure:
• The piping manifold is such that all valves receive balanced flows
• All valves should have isolation valves properly piped in a manner to allow for isolating one valve while maintaining operation
of the remaining valves
Refer to “Piping Diagrams” on page 36.
For optimum valve function, ensure the building recirculation temperature is at least 7°F lower than the desired setpoint temperature.
In addition, it is recommended that the HOT water supplied to the ETV valve is at least 20°F above the desired setpoint.
For applications without constant recirculation it is strongly recommended to add a flow switch. For information on using a flow
switch and the option Flow Prove operation see page 6.
ETV VALVE SIZE MINIMUM FLOW
Up to 1" 5 gpm
1 ¼" and 1 ½" 10 gpm
Over 2" 15 gpm
CAUTION
Heat Timer strongly recommends the use of constant recirculation to minimize the risk of stagment water within the
domestic hot water system which promotes the growth of bacteria such as Legionella.

16 |HEAT-TIMER CORP. 059305–00 REV. E
ETV VALVE INSTALLATION
1 Piping the valve as shown below is considered
the “DEFAULT” configuration.
Ensure to follow the port letter designation or the valve flow direction label.
04 INSTALLATION INSTRUCTIONS
CAUTION
Use a two-wrench method (using one wrench to prevent the valve body from turning or twisting) when tightening piping
onto the valve body connections. Failure to support the valve body in this manner may cause damage to the valve body,
or result in the “B” port coming loose, resulting in water leakage.
NOTE
The valve and actuator can be mounted vertically (upright) or horizontally. DO NOT mount the valve and actuator upside
down. Leave at least 12 inches (30.5cm) service clearance on all sides between the valve/ actuator and any objects (walls,
pipes, controls, etc.).
NOTE
The ETV valve body can be oriented in such a way that the COLD Port A and HOT Port B are interchangeable to
accommodate existing piping. In this “alternate” configuration Port A becomes the HOT port and Port B becomes the
COLD port.

requirements:

• The device can be mounted a maximum of 500 feet (152.4 meters) from the valve location, but should be mounted as near to
the valve as possible to avoid excessive wire runs.
• DO NOT mount the device in a location where it will be exposed to extreme heat, cold, humidity, or moisture.
