Function
Multibox 4 RTL
From the control aspect, the return temperature limiter
integrated in Multibox 4 RTL is a constant proportional controller
(P-controller) without any auxiliary power. It does not need any
electrical connection or other outside power source.
The temperature change of the fluid flowing through (controlled
variable) is proportional to the change of the valve lift (correcting
variable) and is transferred to the sensor by means of thermal
conduction. Any rise in the return temperature due to, for
instance, to lowered heating output of the floor heating system
as a result of outside thermal effects causes the substance in
the temperature sensor to expand and act on the diaphragm
plunger. By means of the valve spindle, this cuts back on the
supply of water in the floor heating circuit. The procedure is
reversed given a falling fluid temperature.
The valve opens when the set limiting figure is exceeded.

Multibox 4 K-RTL
From the control aspect, the thermostatic valve integrated
in Multibox 4 K-RTL is a constant proportional controller
(P-controller) without any auxiliary power. It does not need any
electrical connection or other outside power source.
The change of the room air temperature (controlled variable) is
proportional to the change of the valve lift (correcting variable). A
rise in the room air temperature e.g. from the sun's rays,
results in an expansion of the liquid in the temperature sensor
of the thermostatic head and it acts on the bellows. By means
of the valve spindle, this cuts back on the supply of water in the
floor heating circuit. The procedure is reversed given a falling
room air temperature.
Multibox 4 K-RTL is additionally provided with a return
temperature limiter (RTL) which stops the set return temperature
from being exceeded. The valve opens when the set limiting
figure is exceeded.
