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.
INSTALLATION GUIDELINES FIGURE 1 ALLOWABLE MOUNTING POSITION FOR THE HTC ACTUATOR STANDARD AND HTC ACTUATOR WITH LOP CAPACITOR NOTE The HTC Actuator with IP 65 Rating can only be mounted in the vertical position to avoid potential penetration of water into the motor circuit.
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.
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. 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 •...

APPLICATIONS REPLACEMENT OF AN EXISTING HTC ACTUATOR 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.

6. Mount the HTC Actuator onto the valve body making sure the Square Nut is in the U-channel of the actuator. Insert the U-bolt aligning the valve body groove with the actuator. If needed adjust the position of the actuator manually.
Ensure the HTC Actuator is at the lowest position by manual positioning it. See page 7. Ensure the valve stem is at its lowest position by pressing down on the stem. Mount the HTC Actuator onto the valve body making sure the U-channel of the actuator aligns with the valve stem groove.
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.
NOTE On existing wiring with a M800 actuator an external 24V transformer provided power to the actuator. This transformer can be eliminated with the HTC actuator and 24V power can be supplied through the ETV panel. 059297-00 REV. H HEAT-TIMER CORP.

CALIBRATION NOTICE Each time the HTC Actuator is mounted onto the valve, the steps outline in HTC Actuator Calibration must be performed to ensure proper operation and to determine optimum stroke of the actuator. Ensure the HOT supply to the valve is isolated by closing the isolation valve on the HOT supply piping.
IP 65 INSULATION KIT To provide additional protection to the HTC Actuator IP 65, an optional insulation boot (P/N 905045-00) is available. The insulation kit consist of a 2 part shell that will Velcro together. The insulation kit only covers the actuator, not the valve body.
