OP-IHTGPW 7 Day Immersion Timer

Description

OP-IHTGPW 7-Day Immersion Heater Timer – Surface Mounted

The OP-IHTGPW is a robust 7-day timer designed for immersion heaters and other high-demand applications, providing reliable weekly scheduling and effective energy management. Built for surface mounting, it operates on a 7-day cycle with 2-hour tappet intervals, allowing precise control to suit varying daily heating requirements.

Rated for 16A resistive and 8A inductive loads, the OP-IHTGPW is well suited to immersion heaters and general-purpose electrical loads where dependable time-based control is essential. Captive tappets ensure secure and straightforward programming, while multiple operating modes — Timed, OFF, and Constant — allow flexible adjustment to match user needs.

The timer is equipped with volt-free SPDT contacts, providing versatile switching options for different control applications (link removable if required). Installation is supported by earth park terminals and cable clamps, enabling secure and tidy wiring during fitting.

Adding weekly time control with the OP-IHTGPW allows immersion heaters to operate only when required, helping to reduce energy consumption and lower electricity costs. This is particularly beneficial in properties using off-peak or variable electricity tariffs, and controlled operation can also help extend the lifespan of the immersion heater by reducing unnecessary run time.

The OP-IHTGPW is intended for use with resistive and inductive loads and is not suitable for discharge or LED lighting without the use of a contactor. Its durable construction and simple tappet programming make it a dependable solution for efficient weekly time control.
