Frequently Asked Questions

What type of heating systems is the Neomitis RTMA suitable for?

The RTM is a hard wired mechanical room thermostat designed to regulate the temperature of a connected heating or cooling circuit. It is commonly used with central heating systems that operate using a 230V switched live.

What temperature range does the thermostat cover?

The rotary control allows the desired room temperature to be set between 5°C and 30°C. It also includes frost protection at 5°C to help protect the property during cold weather.

Can the RTMA be installed on a standard wall box?

Yes. The thermostat can be mounted on a standard wall box or directly to the wall. The fixing centres are 60mm, and it accepts cable from 0.5mm² to 1.5mm² via screw terminals.

Does this thermostat require batteries?

No. The RTM is a hard wired, mains powered mechanical thermostat, so it does not require batteries for normal operation.

Who should install this room thermostat?

Installation and wiring should be completed by a competent, suitably qualified person. The mains supply must be isolated before the thermostat base is removed or refitted.
