Ordering and technical data

RA-PLUS is a programmable radiator thermostat that enables users to lower the individual room temperature by approx. 3° C during selected periods of the 24 hours of a day, thereby reducing heat consumption without any detrimental e ects on comfort.

The thermostat features two timer programs

– one of them could be used for workdays and the other one for weekends. Up to three heating periods can be preset per day.

The electronics box of the thermostat is easy to remove, thereby allowing access to function buttons and LCD display for clear and convenient checks or modifi cations to programs and heating periods.The integral batteries have a four-year service life.

If the electronics box is turned o or has been removed, the thermostat functions as a normal proportional regulator with a narrow P-band.The thermostat has integral frost protection.

This thermostat is available in versions for new and older Danfoss valves and for valves with M30 x 1.5 connection.

The colour is RAL 9010 (white)

The required room temperature can be obtained

by turning the handle of the thermostat unit.

The room temperatures that correspond to the setting fi gures on the units can be seen from the temperature scales. Indications are for guidance only, since the room temperatures obtained are often a ected by such factors as the conditions of unit integration.

The temperature scales are stated according to European standards at Xp = 0 and Xp = 2° C.

Xp = 0° C is the room temperature at which the valve shuts o , while Xp = 2° C shows the room temperature in the case of a proportional band of 2° C.

The e ective, obtainable room temperature and lowering temperature depend on such factors as the heat installation, the room and the duration of the temperature lowering period.

The electronics box in RA-PLUS can reduce the temperature settings by approx. 3°C if required.
