Optional accessories
• Power supply 230 V AC/24 V DC according to the total electricity consumption of powered wall convectors. Five power
supply unit types are available for 60 W, 100 W, 150 W, 240 W and 480 W. Power supply units are supplied separately for
mounting on the distribution board DIN rail assembly.
• Junction box for mounting 60 W, 100 W and 150 W DC power supply units.
• SIEMENS 24 V DC: RDG (160T) 260T, RDG 260KN thermostats.
• Thermoelectric actuator 24 V DC. Thermostatic LM valves, straight, elbow.
Description of wall mounted with RAB 21-DC or RDG 160T thermostat function
• Wall mounted output is controlled by fan revolutions and by heating/cooling medium flow. Wall convector operating
voltage = 24 V DC.
• RAB 21-DC or RDG (160T) 260T thermostat control the heating/cooling medium valve with a thermoelectric actuator
and in addition control fan speed by controlling voltage of 0–10 V DC. Fan speed may be controlled automatically by
a thermostat or manualy in three speed settings.
• Rated fan revolutions are set at 7 V controling voltage.
Despription of function using BMS (Building Management System)
• Parent BMS system can be used for wall convector control.
• One regulation BMS outlet controls directly valve closing/opening and other outlet of 0–10 V controls fan revolutions.
• Rated output is reached at 7 V DC. Valve and fan supply voltage is 24 V DC.
• Where KNX system is used, the wall convector can be controled with RDG 260KN thermostat. The thermostat comunicates
with KNX system, to which the thermostat sends information and receives order signals for the wall convector.
