WARNING
This Heat-Timer Motorized Tempering Valve is strictly an operating
valve. It should never be used as a “Fail Safe“ 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.

01 OVERVIEW
The HTC (Blue Oval) Actuator is available in 2 main configurations—the standard configuration and the configuration
with the Loss of Power (LOP) Capacitor. The HTC is also available with IP 65 rating that allows outdoor installation
of the valve and actuator, but not the Heat Timer controller. The HTC actuator with IP 65 is only available with
the LOP Capacitor. Finally, the HTC actuator can accept either a current voltage input signal or a floating (OPEN/
CLOSE) signal.
The HTC Actuator is a direct replacement of the earlier actuators, M800 and TR1000 models, found on ETV Plus—
electronic tempering valves installations. The HTC Actuator is also found in the valve and actuator only kits used in
dual valve applications for the current ETV Platinum Plus applications. The following is a listing of part numbers on
the HTC Actuator can be ordered:

IP 65 RATED HTC ACTUATOR
When ordering an ETV Platinum PLUS complete assembly or an ETV
Valve and Actuator kit (as describe above) or the HTC actuator as a
replacement only, the following part number extension is required: -65.
Example: If you have an application requiring a 2 inch ETV Platinum
PLUS complete assembly (P/N 915675-00) that is to have the valve and
actuator installed outdoors, then you would order the following:
P/N 915675-65.
NOTE
The kits include ETV stainless
steel valve body, the HTC
actuator and a 24V transformer.
NOTE
An IP 65 rate actuator will allow
the valve and actuator to be
mounted outdoors, The Heat-
Timer controller is NOT approved
for outdoor installations.

MANUAL OVERRIDE OPERATION
1 The HTC Actuator can be manually position by lowering the Manual tab (1) down.
2 Once the Manual tab is lowered (2), rotate the tab to lower or raise the actuator.
3 Prior to mounting the HTC Actuator, the actuator must be in its lowest position.
4 To return the HTC Actuator back to automatic operation simply return the Manual tab to its upward position.
WIRE TERMINAL ACCESS
To gain access to the HTC Actuator wire terminals, dip switches and on those actuators with a LOP Capacitor the
Capacitor Jumper, the cover must be remove.
1 To remove the actuator cover remove the mounting screw (1) using a Phillips screwdriver.
2 Lift the actuator cover and slide toward the mounting screw direction disengaging the actuator cover clip
from the actuator housing.
3 To mount the cover once the wiring, calibration of the actuator, any dip switch and Capacitor Jumper settings
are completed, slide the actuator cover tab into the actuator. Ensure the actuator cover is seated on the
actuator housing and secure with the mounting screw.

1 Disconnect power to the ETV module through a service switch or circuit breaker.
2 Remove the actuator cover to access the wire terminals by unsnapping the front of the black cover and lifting
toward the rear of the actuator.
3 Prior to removing the wires from the terminals, it is a best practice to label the wiring to ensure proper wiring to
the HTC Actuator.
•Label Terminal G wire as 24V
•Label Terminal GO wire as 24V
•Label Terminal MX wire as V(-)
•Label Terminal X1 wire as V(+)
4 Remove the wiring from the bottom of the actuator. If needed remove any electrical NM connector or conduit
attached to the actuator housing.
5 Pull down the Manual Tab on the actuator and manually lower the actuator and valve stem to the lowest position.
6 Loosen and remove the (2) locking nuts from the U-bolt. Then remove the U-bolt from the actuator and valve body.
7 On the bronze valve body it may be require to loosen the jam nut from the U channel on the actuator. See
Figure 3A page 9.
ETV VALVE AND ACTUATOR INSTALLATIONS—DUAL VALVE APPLICATIONS
In applications where the ETV valve and actuator kit is applied in a dual application with an ETV Platinum Plus
complete assembly, reference the ETV Platinum Plus installation manual for guidelines on installing the valve and
the wiring of the actuator and 24V transformer.

WARNING
ELECTRICAL SHOCK HAZARD! Disconnect electrical power to the device before servicing or making any
electrical connections. Failure to do so may result in severe personal injury or death.
Follow all local and state electrical codes when installing the unit. All wiring must meet or exceed local,
state, federal codes and requirements.
WARNING
SCALD HAZARD! To avoid any potential of a scald hazard it is recommended to isolate the valve from the
system by closing at a minimum the isolation valve on the HOT supply to the valve.

1 Disconnect power to the ETV module through a service switch or circuit breaker.
NOTE: Although the TR1000 actuator contains a service switch it is not recommended for this type of
servicing to use it as power will still be present on the wiring from the ETV module and a shock hazard
is still present.
2 Remove the actuator cover to access the wire terminals by removing the (2) mounting screws on the front
red cover.
3 Prior to removing the wires from the terminals, it is a best practice to label the wiring to ensure proper wiring to
the HTC Actuator.
•Label Terminal B wire as 24V.
•Label Terminal O (right of Terminal B) wire as 24V.
•Label Terminal O (left of Terminal E) wire as V(-).
•Label Terminal E wire as V(+).
4 Remove the wiring from the bottom of the actuator. If needed remove any electrical NM connector or conduit
attached to the actuator housing.
5 Push the Red Manual Crank Handle down and lift the lever. With the Crank Handle pushed down, rotate the
handle counterclockwise to lower the actuator and valve stem down to its full position.

1 Disconnect power to the ETV module or control through a service switch or circuit breaker.
2 Route all wiring through the bottom of the actuator. Use the proper NM connector to secure the wiring and
avoid potential damage to the wiring.
NOTE: On HTC Actuator with IP 65 rating the actuator is provided with a Liquid Tight Conduit
Connector fitting, see figure 8. Liquid Tight conduit is required for any outdoor installations. Check
local, state electrical codes for compliance.
3 Terminal designations for current voltage proportional modulation input see ETV and Modulation wiring on
pages17–19.
4 Terminal designations for floating signal input see page 17.
5 Once all wiring is complete return power to the ETV module or control, placing the actuator into service.
6 If the actuator contains a LOP Capacitor it will require about 2 minutes of power being supplied to fully charge.
