WARNING
This Heat-Timer Motorized Tempering Valve is strictly an operating
valve. It should never be used as a “FailSafe” or “Anti-Scald” valve.
A separate Anti-Scald device can be installed in conjunction with
this motorized tempering valve. All equipment must have their own
certified limit and safety controls required by local codes.

OVERVIEW
The Heat-Timer electronic tempering valves are 3-way valves. They are components of the Heat-Timer ETV control package.
Though the ETV control is used primarily in domestic hot water temperature regulation, it can be used in other applications as
well. Heat-Timer offers two types of electronic tempering valve actuators: an actuator that requires external power (M800) using
a transformer and an actuator that uses the ETV control 24 VAC power (TR1000). The selection of the actuator depends on the
size and type of valve material selected. This manual demonstrates the actuator using the ETV power source (TR1000) only. This
actuator is used with larger size stainless-steel tempering valves (2” and 2 ½”). These stainless-steel tempering valves are primarily
used in areas adhering to strict Lead-Free codes.

ETV OPERATING CONCEPT
The 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 ow in the valve during no
usage periods. The ETV operation requires the use of a circulating loop pump to maintain a circulating loop temperature.
DESIGN CONSIDERATIONS
CIRCULATING RETURN LOOP
The 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 LOOP
The cold water feeding the hot water supply source MUST have a Thermal Heat Loop. This 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 ow
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.

ACTUATOR TO STAINLESS-STEEL VALVE ASSEMBLY
After installing the valve on the piping system, follow
these instruction to mount the actuator to the valve:
1. Close the isolation valve feeding the hot port of the
3-way valve.
2. Manually close the valve by pushing down on its stem.
3. Turn the actuator power Off using the Power Switch.
4. Manually move the actuator to the open position. See
“Actuator Manual Operation” on page 4.
5. Loosen the Actuator Stem Locking Bracket and remove
the Actuator Body Locking Bracket.
6. Mount the actuator to the valve.
7. Install the Actuator Body Locking Bracket making sure
to align the valve groove with the bracket protrusions.
Secure the bracket in place by tightening its two hex
screws.
8. Gradually, bring the actuator stem down until the valve
stem is aligned with Actuator Stem Locking Bracket.
Then, tighten the bracket’s two hex screws.
9. Turn the actuator Power Switch on. Then wait until the
valve nishes it partial calibration.
10. Calibrate the Actuator to the valve. See “Actuator
Calibration” on page 5.
11. Open the isolation valve feeding the hot port.
WARNING
After assembling the actuator to the valve and
wiring the actuator to the ETV, the actuator
MUST be fully calibrated. Failure to CALIBRATE
the actuator motor before operation may
damage the valve and actuator. Heat-Timer
warranty does not cover these damages

WIRING THE ACTUATOR
This actuator accepts a 0-10V modulation signal from the ETV control.
In addition, it requires 24 VAC power that is also supplied by the ETV
control.
ACTUATOR MODULATION SIGNAL WIRING
• Wire actuator terminal (E) to ETV terminal (15).
• Wire actuator terminal (O next to the E) to ETV terminal (16).
ACTUATOR POWER WIRING
• Wire actuator terminal (B) to ETV terminal (4).
• Wire actuator terminal (O next to the B) to ETV terminal (3).
• Failure to observe actuator power polarity may damage equipment.
WARNING
To avoid damage to the equipment, DO NOT replace or install
wires when power is connected to the actuator or the control.

WARNING
After assembling the actuator to the valve and wiring the actuator
to the ETV, the actuator MUST be fully calibrated. Failure to
CALIBRATE the actuator before operation may damage the valve and
actuator. Heat-Timer warranty does not cover these damages
Each time the actuator is assembled to the valve, the actuator must be calibrated using the
following steps:
1. Close the isolation valve feeding the tempering valve hot port.
2. Make sure that the actuator Power Switch is set to On.
3. Power the actuator. See ETV installation manual.
4. Start the calibration by holding down the Calibration Button for over 3 seconds. The
actuator will fully open and then fully close the valve. During this process, both LEDs
will blink at the same time.
5. When the actuator returns to its normal operating position, the calibration has ended.
6. Open the isolation valve feeding the tempering valve hot port.

DIP SWITCHES
The actuator dip switches are preset in the factory. However, it is important to have the
factory settings when troubleshooting.
•. All dip switches are set to Off except for Dip Switch 6 and 8 that are set to ON.

DISPLAY MESSAGES
• This actuator has a 4 letter alphanumeric display.
• Under normal operation, the left most letter will be followed by a number. The
character can be either a “C” or an “F”.
• The letter “C” represents the current input signal. Example: C 97.
• The letter “F” represents the current valve position . Example: F 98.
• The actuator will alternate the display of both C and E values.
• When “ERR “ is displayed, it indicates an error in the actuator positioning. In this
case, the actuator needs to be re-calibrated.
LEDS
• The LEDs indicate the actuator movement direction.
• When the actuator is being calibrated, both LEDS will blink at the same time until
the process ends.
• The White LED is lit when the actuator opens the valve.
• The Red LED is lit when the actuator closes the valve.
LEDs
TROUBLESHOOTING
Valve calibrates but does not move afterwards
• Check the modulation signal wiring to the actuator (terminals O and E). If the modulation signal wiring is not connected or is
wired incorrectly, the valve will not move after calibration. See “Wiring the Actuator” on page 5.
• Check the modulation signal value. It may be that the modulation signal matches the valve location after calibration. See
“Display Messages” on page 6.
• Check the AC voltage going to the actuator. The actuator is designed to work between 19 and 26 VAC. If the voltage above or
below this range the valve may stop responding to the modulation signal.
Valve does not move
• Make sure that there is power going to the actuator (terminals B and O). The actuator power is polarity sensitive.
• The valve may be jammed with debris. This can be tested by removing the actuator and testing the valve movement manually by
pushing and pulling on the valve stem.
• If the previous tests proved no problems, then the actuator may need to be replaced.
Actuator Display Reads ‘ERR’
• Re-calibrate the actuator to the valve. See “Actuator Calibration” on page 5. If the problem persists, contact the factory.
