4ETV Platinum Plus Installation and Operation ManualDetailed OperationOverviewThe ETV Platinum Plus (Electronic Tempering Valve) is a hot water temperature control capable of operating oneor more electronic motorized mixing valves to regulate the system water temperature. The electronic mixingvalves are controlled using any of its voltages or current output modulation signals. Its modulation PID isdesigned 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 controlthe electronic motorized Actuatorthe 3-way mixing valvean immersion temperature sensorIf applicable for added protection, the ETV Platinum contains a power loss capacitor which will close thehot water supply to the mixing valve on a loss of power. The ETV Platinum Plus control can also beconfigured to close the hot water supply to the mixing valve if the mixed outlet temperature exceeds theAlarm Limit. It does that by operating a TMC Safety Valve mounted on the hot water supply.ETV Operating ConceptThe ETV Platinum Plus control modulates the electronic motorized mixing valve to maintain atemperature setpoint. It does that by mixing two different water temperatures from two differentsources; 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 citywater system.The cold water inlet is joined with the circulating loop return pipe to help maintain flow in the valve duringperiods of no usage. The ETV Platinum Plus operation requires the use of a circulating loop pump tomaintain the loop temperature.To save on energy, the ETV Platinum Plus provides a 7-day schedule to help reduce thewater temperature during periods of low usage.TMC Operating ConceptIn addition to maintaining the mixed output setpoint, the ETV Platinum Plus helps protect the system fromexcessive water temperatures. It does that by closing a TMC Safety Valve feeding the mixing valve's hot water.When the mixed outlet exceeds the alarming temperature setpoint (see “TMC Setpoint” on page45) for the delayed period (see “TMC Trigger Delay” on page 45), the control closes the TMC valve blocking allhot water flow to the mixing valve and triggers an alarm.ETV TMC Operating ConceptThe ETV TMC mode combines both the ETV and TMC modes. In this mode, the ETV Platinum Plus controlsthe valve to maintain temperature, and monitors the outlet temperature to ensure the specified temperatureis not exceeded.059305-00 Rev. DHeat-Timer Corp.

Detailed Operation5ETV Platinum Plus InputsSystem Temperature SensorThe ETV Platinum Plus is designed to connect to the provided Heat-Timer temperaturesensor 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 ofthe motorized mixing valve, and before any takeoffs.Aux Sensor/Switch Inputs - optionalAuxiliary 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 inthe COLD and HOT inlet of the valve, the sensor can be configured as Feed-Forward to provide anadditional 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 isrecommended to install the Auxiliary Temperature Sensors at least 6 feet (1.8 meters) from the valve.NOTE: Alarms for auxiliary sensors are available with RINET communication option only and is accessedvia internet through BuildingNet.Flow Prove - optionalThe 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 duringnormal valve operation, the ETV Platinum Plus will keep the mixing valve position at its latest openingpercent or return the mixing valve to a predetermine position as set by the installer.NOTE: If the current valve position is lower than the preset valve position setting, the valve will remainat the current position.NOTE: IT is the responsibility of the installer to properly select the flow switch and the gpm flow raterequired for the switching needed for the application.4-20mA Remote Setpoint - optionalThe 4-20mA remote setpoint can be used when it is desirable to set the ETV Platinum Plus setpointremotely using an EMS system. Any signal that is less than 2mA or greater than 22mA will close the mixingvalve and trigger an alarm (see “Alarm Messages” on page 35).NOTE: The ETV Platinum Plus does not source power to the 4-20mA terminals. The EMS system mustprovide the excitation voltage.Heat-Timer Corp.059305-00 Rev. D

6ETV Platinum Plus Installation and Operation ManualETV Platinum Plus OutputsActuatorsWhen the Control Mode is set to ETV or ETV TMC, the control operates a single or dual motorized mixing valveto maintain the hot water temperature at the Setpoint. This is done by sending 24Vac power and amodulation signal to the mixing valve.During loss of power the actuator will automatically position itself and the valve to a full COLD position. Oncepower is restore the actuator will return to normal operation.TMC ValveWhen the Control Mode is set to TMC or ETV TMC, the ETV Platinum Plus uses a TMC Safety Valve to closethe hot water feed to the mixing valve when excessive mixed temperatures exceed the Alarm Limit (see “TMCSetpoint” on page 45) for the specified Delay Alarm period.The control can manage either a motorized ball valve (powered OPEN and powered CLOSED) or aNormally Open (N.O.) or Normally Closed (N.C.) solenoid type valve. Heat-Timer recommends the useof a motorized ball valve with battery backup TMC valve for better performance during poweroutages.NOTE: The ETV Platinum Plus does not source power to the TMC valve terminals. An external power sourceis required.TMC Lockout OutputThe TMC Lockout can be used to provide a notification that the unit has gone into lockout. Devices that canbe connected to the ETV Platinum Plus include: Vis-U-Alarm, audible alarm, Remote Management System, orany other device that requires a switch closure or an open switch to trigger an alarm.NOTE: The ETV Platinum Plus does not source power to the TMC Lockout terminals. An external power source isrequired.The TMC Lockout LED will be lit whenever the control is in lockout. To exit TMC Lockout mode, the cause ofthe alarm must end or be corrected, the System Sensor reading must drop below the TMC Limit, and theReset button must be pressed (see “Reset Lockout” on page 51).059305-00 Rev.

Calibrating the Actuator (refer to page 29).8. Completing initial programming of the ETV Platinum Plus (refer to page 36).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 wiringDesign ConsiderationsWhen installing the system, certain design considerations must be taken into account. These include: General Piping Guidelines (isolation valves, drain cocks, unions, etc.)Sensor Probe LocationsOptional TMC Safety Valve PipingBuilding recirculating loopThermal Trap or proper use of check valvesDual/Parallel ETV Valve PipingSee “Piping Diagrams” on page 30 for more information.Heat-Timer Corp.059305-00 Rev. D

12ETV Platinum Plus Installation and Operation ManualGeneral Piping GuidelinesThe 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/orfederal 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 andsensors.5. Include drain valves (as shown in Figure 2) to assist in servicing of the ETV valve and sensors.Figure 2: Piping GuidelinesSensor Probe LocationsSensor probes must be installed within the flow of water in the pipe (see Figure 2). When possible, use atee fitting rather than an elbow fitting where the piping changes direction within the allowable sensorplacement distance from the valve. The sensor probe is then placed in the run of the tee fitting as shownas 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 probesensor should be position at the centerline of the piping (see optional HOT or COLD probe sensor in Figure2). 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.TMC Safety Valve PipingThe optional TMC Safety Valve is typically piped between the hot water source (a storage tank orboiler coil) and the Hot inlet of the ETV valve. For an optional TMC Safety valve location, refer to“Piping Diagrams” on page 30.059305-00 Rev. DHeat-Timer Corp.

Installation Instructions13Building Recirculating LoopFor proper operation of the ETV Platinum Plus, the ETV valve must be installed in a system with constantrecirculation. The building recirculation must be piped in a manner that allows recirculating flow to theCOLD side of the ETV valve and to the water heating source. Refer to “Piping Diagrams” on page 30.The recommended size of the recirculation loop and pump should be as follows:ETV Valve SizeMinimum FlowUp to 1"1¼" and 1½"over 2"5 gpm10 gpm15 gpmFor optimum valve function, ensure the building recirculation temperature is at least 7 F lower than the desiredsetpoint temperature. In addition, it is recommended that the HOT water supplied to the ETV valve is at least20 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 5.CAUTIONHeat Timer strongly recommends the use of constant recirculation to minimize therisk of stagment water within the domestic hot water system which promotes thegrowth of bacteria such as Legionella.Thermal TrapA thermal trap must be used to prevent the higher temperature water in the hot water supply source frommigrating up and entering the cold-water inlet side of the mixing valve during low or no demand periods. Thethermal 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 recirculatingpump between a heating source and storage tank, a check valve may be used.Multiple/Parallel Valve PipingFor high volume applications the ETV Platinum Plus control module can modulate two or morevalves 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 whilemaintaining operation of the remaining valvesRefer to “Piping Diagrams” on page 30.Heat-Timer Corp.059305-00 Rev. D

14ETV Platinum Plus Installation and Operation ManualETV Valve InstallationCAUTIONUse a two-wrench method (using one wrench to prevent the valve body fromturning or twisting) when tightening piping onto the valve body connections. Failureto support the valve body in this manner may cause damage to the valve body, orresult 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 valveand 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.).Figure 3: Mounting of the ETV valve and actuator1. Piping the valve as shown below is considered the "DEFAULT" configuration.Figure 4: "Default" ETVvalve configurationEnsure to follow the port letter designation or the valve flow direction label.NOTE: The ETV valve body can be oriented in such a way that the COLD Port A and HOT Port B areinterchangeable to accommodate existing piping. In this "alternate" configuration Port Abecomes the HOT port and Port B becomes the COLD port.059305-00 Rev. DHeat-Timer Corp.
