Frequently asked questions

Can these heaters be used in wet rooms?

The heaters are rated to IP44, meaning they are protected from from splashing water coming from any direction making them suitable for areas with exposure to moderate moisture for example bathrooms and sheltered outdoor areas. They must not be used in high moisture zones, or where jets of water are present, for example sauna's, wash down rooms, laundries, etc.

Can I install the RTH external control in another room?

No, the RTH must be mounted in the same room as the heater it controls.

How do I control the heater from another room?

You will need a thermostat with a remote sensor, capable of measuring up to a maximum of 70C. It will also need to be rated to the full phase current of the heater. With reference to the wiring wiagram it should replace the dotted box marked 'External control'.

Do you supply such a thermostat?

We do not. Every customer's requirements are different, some want devices with timers, digital displays, or to be suitable for building into control panels. So we leave to the customer to source a device that meets their needs.

Can I control the heater remotely simply by switching the supply?

No, the fan needs to run continuously. Switching the supply will disconnect the supply to the fan, causing the protective over heat cut out to operate. You need a remote thermostat as described above.

How long will it take for the room to reach the required temperature?

That depends on the heatloss of the room being heated and the air changes at the required final temperature. It is the responsibility of the system designer or specifier to make sure the heater(s) selected have a big enough output.
