The EPH C1P Replacement 2-Port Actuator is designed for homeowners and HVAC technicians looking to restore or maintain efficient flow control in their central heating systems.

The main benefit is its broad compatibility and ease of installation, though users should ensure their specific valve body matches the standard 2-port configuration before purchase to avoid compatibility errors.

No, the C1P is strictly designed for 2-port valves only.
Yes, the unit comes with a detachable cable for convenient installation.
It is specifically compatible with Honeywell and Horstmann systems. Always verify your valve manufacturer before installation.
Usually, no. Because the C1P is a replacement head, it can often be swapped while the valve body remains installed on the pipework.
The EPH C1P is covered by a 5-year warranty.
Check the wiring connections at the wiring center and ensure the thermostat is sending a 230V signal to the actuator.
Verify that the valve stem is not seized; if the valve body is stiff, the actuator may struggle to turn it.
Check if the manual override lever on the side of the actuator is stuck in the 'open' position.
To install the EPH C1P, ensure the heating system is fully powered down at the main isolation switch. Use the provided adaptor plate to align the actuator with your current valve body. Once the plate is secured, the actuator head clicks into position. Connect the detachable cable to your system's wiring center according to the manufacturer's color-coding.
Care instructions are straightforward: keep the exterior of the actuator dry and free of dust. During annual boiler servicing, it is recommended to check that the actuator cycles correctly without making grinding or clicking noises, as this indicates a healthy internal gear assembly.
