OVERVIEWThe ETV (Electronic Tempering Valve) is a hot water temperature control. It operates one or two electronic motorized mixing valves to regulate the water temperature. It modulates the electronic motorized valves using a variety of voltages or a 4-20mA modulation signal. Its modulation PID is designed to respond quickly in temperature control of domestic hot water applications.The ETV consist of four primary components, the ETV control; the motorized electronic actuator; the 3-way mixing valve; and an immersion temperature sensor. Heat-Timer offers two valve materials, bronze or stainless-steel. Depending on the valve material and valve size selected, the actuator used may vary. See ETV literature for additional information.For added safety, the ETV control can be used with the TMC control (Temperature Monitoring Control). The TMC, using a solenoid valve, shuts the hot water supply to the electronic motorized valve if the hot water temperature became excessively hot. See TMC documentations for additional information.

ETV OPERATING CONCEPTThe ETV control modulates the electronic motorized mixing valve to maintain a temperature set point. 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. On the other hand, 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 no usage periods. The ETV operation requires the use of a circulating loop pump to maintain a circulating loop temperature. The ETV provides Setback features to help reduce the water temperature during low usage periods to save on energy. It has a Setback differential set point and a setback input. In addition, the ETV can accept a remote 4-20mA temperature set point to help integrate into existing BMS systems.

DESIGN CONSIDERATIONSCIRCuLATING LOOPThe ETV is designed to operate in a system that has a circulating return loop with a circulating pump. The circulating return loop temperature must be at least 7°F less than the ETV set point temperature. This temperature differential prevents the mixed temperature from rising continuously. In addition, the temperature of the hot water entering the valve must be at least 20°F hotter than the ETV set point temperature.

VERTICAL LOOPThe cold water line to the hot water supply source MUST have a Thermal heat loop. The Thermal heat loop prevents the higher temperature water in the hot water supply source from backing up and entering the cold water inlet side of the mixing valve during low flow periods. The Thermal heat loop can be installed either up or down, but must be a minimum of 32 inches as measured from pipe-center to pipe-center.

ETV TO ACTuATOR VOLTAGE WIRINGThe ETV control is designed to operate a variety of actuators. Depending on the actuator used and its settings, the ETV can send a 0-10V modulation signal to the actuator. In addition, most actuators can use the 24 VAC power source supplied from the ETV terminals (3) and (4). However, some actuators may require the use of an external power source (Transformer Kit HT# 950023-00). If the actuator requires and external power source, Heat-Timer packages the transformer with the actuator. See the specific actuator installation manual for additional instruction on wiring, calibration, and dip switch settings.

VOLTAGE ACTuATOR uSE ExTERNAL TRANSFORMER1st Actuator Voltage Signal Terminals (15) and (16)2nd Actuator Voltage Signal Terminals (17) and (18)• The Voltage signal for the first actuator uses Terminal (15) (Volt 1 +) on the ETV control. Connect this terminal to the actuator

terminal (X1). Terminal (16) (Volt 1 -) on the ETV control connects to the 1st actuator terminal (MX).• If an additional actuator is used, then connect terminal (17) (Volt 2 +) on the ETV control to the 2nd actuator terminal (X1) and

connect terminal (18)(Volt 2 -) on the ETV control to the 2nd actuator terminal (MX).• This type of actuator requires an external power source. Heat-Timer provides an external transformer with this actuator.• Connect the transformer low voltage wires to the actuator terminals (G) and (GO). Do not share the same transformer with

other equipment.

WARNINGTo avoid damage to the valve and actuator, the actuator MuST BE FuLLy CALIBRATED before operation. Calibration

must be done every time the actuator and the valve are reassembled. See actuator manual for Calibration instructions.

to terminal 1 and 2. Turn the power off and back on.• If unsuccessful, make sure the fuse on the back of the Enclosure

Display Module is working by checking it with a continuity meter. If no continuity exists, replace the fuse with a 20 mm 2.5 amp fuse.

Sensor Reads OPEN or SHORT and Valve is Fully Closed• The ETV will close the valve when the System Sensor reads Short or Open. See “Display Messages” on page 9.

• If the System Sensor reads Open, short the sensor input terminals. The display should read Short. If it does, check the sensor wiring. If it doesn’t, the ETV may be damaged.

• If the System Sensor reads Short, remove the wires from the input terminals. The display should read Open. If it does, check the sensor wiring. If it doesn’t, the ETV may be damaged.

Sensor Reads Incorrect Temperature• Remove the wires from the Sensor input terminals. The display

should change to read Open. If it doesn’t, the ETV may be damaged. Otherwise, take an ohm reading across the detached sensor wires. The ohm reading should correspond to the Temperature Sensor Chart. If the difference is within 5°F adjust the Trim of the sensor. Otherwise, the sensor may need to be replaced.

No Hot Water• Shutdown Shorted - If the ETV displays “Shutdown”, check the

Shutdown terminals. If the Shutdown terminals are shorted, the ETV will close the valve. See “Shutdown” on page 8.

• If the ETV was using an external 4-20mA set point, the signal may be below 2mA or above 22mA. See “4mA and 20mA Set Point” on page 10.

ETV Does Not Move the Floating Motorized Valve• Firstcheckthevalvewiring-Make sure that the wiring to the

actuator power terminals has between 20 to 24 VAC. If the voltage is higher or lower, the actuator may stop moving or get damaged.

• ValveModulatingSignal-Make sure that the ETV Modulating Signal is set to 0-10V to match the actuator’s signal. Press the BACK button to read valve opening %. Your voltage signal meter reading must correspond to that ETV’s %. If the valve-opening % was at 40%, then the signal should read 4VDC. If it did not, the ETV control is damaged. See “Default Display” on page 9.

Outlet Temperature Fluctuates• ChecktheCirculatingLoopPiping-The ETV requires the use

of a circulating pump and a circulating loop. The loop temperature must be at least 7°F lower than the set point. If the loop is insulated, its temperature may not be much lower than the set point. This will cause outlet temperature oscillation. To reduce the oscillation, install an aquastat on the circulating loop to operate the circulating pump. Set the aquastat to at least 10°F below the ETV set point. See “Circulating Loop” on page 4.
