## Description

Automatically activate extractor fans based on humidity levels, with adjustable run-on timer and manual pull cord control for versatile, moisture-clearing ventilation.

Review: Great module when you understand how to use the connections - I bought one of these alongside the actual iCON fan to replace an existing, failed Aitflow unit. As a drop-in replacement it works great. I also took this opportunity to switch to a humidity module. I can’t think of any cons other than that quieter units from other brands are available. The instructions weren’t exactly clear how you configure the module to run so I’ll add some notes here from my own googling. A key aspect not made explicitly clear in the instructions is that you do not have to connect the T (Live Trigger) terminal which comes from the light switch. It is very likely that existing and new installations will use 3 core cable which have colours: brown, grey and black. A good practice is to use those wires as follows putting a bit of electrician tape on it for future reference to state purpose: Module connections: L - Permanent Live - core brown N - Neutral - core grey (tape it blue) T - Live trigger - core black (tape it brown) If you don’t want to use a timer or humidity function, and just use the light switch, you can have core black going to L. If you don’t want to use the timer (which needs T) - don’t connect T. If you don’t want to use the pull cord I found it can be rolled-up and taped inside the unit. Note that the pull cord is electronic, not a mechanical switch, and is only used to turn the fan ON. Repeated pulling of it resets the timer to start again. If you turn the timer to its minimum setting, that was about 2 minutes in my test. I had no need for the pull cord as I have an isolation switch outside my bathroom which is easier to access. In the rare situation when you want to disable the fan - perhaps you are having a bath listening to music - that isolation switch can be used. I am using the module as humidity detection only and I have not changed the factory set dial. It comes-on three minutes into a shower. If you connect T you get the fan on with the lights every time but the humidity detector will keep it on until steam level drops. I don’t see the point of that mode myself. If you are pondering which module function to use - I would say that when using the toilet at night without turning on the fan, and potentially disturbing others, this is a really good feature of the humidity detector.
Review: Run on timer , good for shower room - Works well with its related extract fan

## Features

- Compatible with iCON 15, 30 & 60 Fans – Designed for seamless integration with the full Icon fan range. Easily upgrade or replace without changing the entire fan unit.
- Adjustable Run-On Timer (2–45 Minutes) – Keeps the fan running after switch-off to clear moisture and odors. Factory pre-set to approx. 15 minutes, adjustable using the included tool.
- Humidity Sensor (40–90% RH) – Automatically activates the fan when humidity rises. Factory pre-set to approx. 70% RH. Adjust sensitivity using the supplied adjustment tool.
- Pull Cord Activation with Timer Control – When installed in an iCON fan, the module allows manual activation via the integrated pull cord. Once triggered, the fan runs according to the adjustable timer settings (2–45 minutes). This module supports two activation methods: humidity sensing and pull cord activation.
- Recommended Humidity Settings for UK Climate – UK indoor humidity often ranges between 70–90% RH. Setting the module to 40% RH may cause the fan to run continuously. If the fan takes too long to switch off, adjust the humidity setting closer to 70–90% RH for better performance.

## Questions & Answers

**Q: What are the iCON Fan Sizes?**
A: The iCON fan range includes 3 sizes: iCON 15 (100mm), iCON 30 (100mm), and iCON 60 (150mm). Installation holes are larger than outlet sizes to fit the housing.

**Q: Who can install my iCON fan?**
A: Only a qualified electrician can install your iCON fan. Installation must follow UK Building Regulations Part P and IET Wiring Regulations, or local standards. Always use the manufacturer’s instructions to ensure correct and safe installation.

**Q: How do I clean my iCON fan?**
A: Always isolate the fan from the power supply first.

**Q: How does the iCON iris/shutter open and close?**
A: The iCON iris/shutter opens via a wax actuator that heats when the fan is on, pushing a clip to open the shutter. After installation, turn off power and wait ~2 mins for the actuator to cool before fitting the cover to ensure proper function.

**Q: What if I buy the fan without a control module?**
A: Without a control module, the fan works as a basic unit with light switch activation. For features like timer, humidity, or motion sensor, a separate control module is required which is available for purchase separately.

### ⭐⭐⭐⭐⭐ Run on timer , good for shower room
*by A***R on 28 December 2025*

Works well with its related extract fan

### ⭐⭐⭐⭐ Reliable?
*by E***3 on 5 January 2019*

Just bought a replacement module for my timer/humidistat Airflow bathroom fan. Original module had lasted 7 years until it needed replacing. Subjective whether you consider this reliable. I have a timer only version which lasted less than that. But as the module is so easy to replace (compared to fitting a new fan) I guess it's worth it. If you were to choose a standard bathroom fan (£20.00 - £30.00), in my experience these can last anywhere between 18 months and 10 years. Thing I really like about these fans is the shutter. No cold drafts in the bathroom. They look good too. On balance worth the money but not brilliant. Just very good.
