Aptel KTX4 for Terma towel radiators, chrome — control module for electric dry operation

Aptel KTX4 for Terma towel radiators, chrome is an electronic control module developed to enable dry (electric-only) operation of compatible Terma towel radiators. Designed for integration with radiator electronics, the chrome-finish module provides timed switching, temperature control and safe activation of the electric heating element. The unit is intended for use where an electric control solution is needed to operate a towel warmer independently from a central hot-water system.

Advantages

The control module offers precise electronic regulation of heating periods and set temperature, helping maintain a comfortable towel-drying environment while optimising energy use. Built for compatibility with Terma towel radiators, it supports safe activation of the electric element and integrates with radiator functions without modifying the primary heating system. Its chrome appearance matches metallic radiator finishes for a discreet aesthetic.

Suitable for

• Bathrooms where a Terma towel radiator needs independent electric operation
• Situations requiring timed heating cycles or scheduled runtime
• Installations where a chrome-finish control module is preferred for visual match

When it may not be suitable

The module is intended specifically for enabling dry electric operation of compatible Terma towel radiators and may not be suitable for radiators from other manufacturers or models that lack the required electrical interfaces. It is not a substitute for full central-heating control and does not replace hydraulic components or plumbing work needed for water-based radiator systems.

Key specifications

• Function: electronic control module for dry (electric-only) operation
• Control features: temperature regulation and timed runtime control
• Finish: chrome
• Intended mounting: integration with Terma towel radiator electrical interface
• Primary use: safe activation and management of the electric heating element

How to use

Install the Aptel KTX4 control module according to the radiator and module installation instructions, ensuring power is disconnected during fitting. Connect the module to the radiator's designated electrical interface and to the supply as described in the radiator documentation. Use the module controls to set desired temperature and programme heating periods or runtime. Verify proper operation after installation and consult a qualified electrician if wiring or configuration assistance is required.

What to consider before purchase

• Compatibility with your specific Terma towel radiator model and its electrical interface
• Whether dry (electric-only) operation is appropriate for your heating setup
• Required electrical supply specifications and local wiring regulations
• Need for professional installation if you are not experienced with electrical connections

Usage recommendations

For reliable and safe operation, verify compatibility with the Terma radiator manual, follow installation instructions precisely, and have electrical connections performed or checked by a qualified professional. Use scheduled runtime and temperature settings to balance comfort and energy use.
