Product Information
Full details
The Manrose T12HP is a remote humidistat transformer designed for 12V low voltage extractor fans, specifically those installed in shower or bath splash areas. It offers crucial safety by powering fans remotely, allowing control via an integrated pull cord or humidity sensor. A key benefit is its flexibility in mounting location, such as in a loft or high on the ceiling, away from direct water exposure. The primary caveat is its reliance on a compatible 12V SELV Manrose extractor fan.

FAQs
What is SELV and why is it important?
SELV stands for Safety Extra Low Voltage. It means the voltage is kept at a very low level (12V in this case) and isolated from the mains supply, making it safe for use in areas where water is present, like showers and baths.
Can I use this transformer with any 12V fan?
No, this transformer is specifically designed for use with 12V SELV Manrose low voltage extractor fans. You must confirm your fan's voltage and power requirements match the T12HP's output (12V AC 50Hz 25VA).
Where is the best place to mount the transformer?
The T12HP can be mounted in a loft space or high on a ceiling, away from direct water splash, ensuring its longevity and safety.
How do I adjust the humidity setting?
The humidity level is adjusted using the adjuster knobs located on the transformer unit. Refer to the product manual for precise adjustment ranges (typically 40-95% RH).
What is the function of the integral timer?
The integral timer allows the fan to continue running for a set period (adjustable between 1 and 20 minutes) after the humidity level has dropped below the set point, ensuring adequate drying of the room.
Does this unit come with a fan?
No, the Manrose T12HP is a remote humidistat transformer and pull cord unit. It requires a separate compatible 12V SELV Manrose extractor fan.
What are the dimensions of the unit?
The unit has dimensions of Height: 82mm, Length: 145mm, and Depth: 65mm. It is fitted on a standard 25mm deep double pattress.
Troubleshooting
Fan does not turn on automatically.
Check that the humidistat is set to a level below the current room humidity. Ensure the 12V fan is correctly connected and powered. Verify the mains power supply to the transformer is active.
Fan does not turn on with the pull cord.
Ensure the pull cord is correctly connected to the override switch. Check the mains power supply to the transformer and the connection to the 12V fan.
Fan runs continuously and does not turn off.
The humidistat may be set too high or the room humidity is consistently above the set point. Check the humidistat setting. Ensure the timer is not set to its maximum duration if the fan is still running after that period.
Neon light is not on.
Check the mains power supply to the transformer. If power is present, the neon indicator itself may be faulty or the transformer may have failed.
Pros and Cons
Pros
- Enhances safety in bathrooms by powering low voltage fans remotely.
- Automatic humidity control reduces moisture buildup effectively.
- Adjustable timer ensures adequate ventilation.
- Manual pull cord override offers user convenience.
- Durable and easy-to-clean ABS construction.
- Flexible installation options suit various bathroom layouts.
Cons
- Requires a compatible 12V Manrose SELV extractor fan to function.
- Transformer itself is not a fan; it's a control and power unit.
- Installation may require professional electrical knowledge for safe wiring.
- Limited to 12V AC 50Hz 25VA output, so fan compatibility must be checked.
- The pull cord switch is located near the transformer, not necessarily at the fan's location.
Setup, Compatibility & Care
Setup: This unit is designed to be wired between the mains power supply and a compatible 12V SELV Manrose extractor fan. It should be installed by a qualified electrician. The transformer can be mounted in a loft space or high on a ceiling, typically alongside a pull cord light switch. Ensure all connections are secure and comply with local electrical regulations. The unit comes complete with a standard 25mm deep double pattress for mounting.
Compatibility: The Manrose T12HP is specifically designed for use with 12V SELV Manrose low voltage extractor fans. It outputs 12V AC 50Hz at 25VA. Always verify that your extractor fan is compatible with these specifications before installation.
Care: The casing is made from impact-resistant, high gloss ABS thermoplastic, making it durable and easy to clean. Disconnect power before cleaning. Wipe the exterior with a soft, damp cloth. Avoid using abrasive cleaners or solvents.
